For most above-ground pool owners, I’d start with the TURBRO Beluga B50V, whose 50,000 BTU inverter heat pump offers a strong middle ground between capacity and controlled operation. The Raypak Crosswind 40i stands out for buyers who want both heating and cooling, while the Intex Solar Pool Water Heater Mat is a simpler, sunlight-dependent option. The main tradeoffs are heating speed, operating conditions, installation needs, and whether your pool’s size suits the unit. Read on for the full breakdown of all 14 picks and how I’d match them to different pools and priorities.

Key Takeaways
- The lineup spans very different pool sizes: compact 18,000 BTU heat pumps are listed for pools around 5,200 to 6,500 gallons, while larger heat pumps and gas models target substantially greater heating demands.
- Inverter heat pumps lead the balance-focused conversation: the TURBRO Beluga B50V combines 50,000 BTU capacity with inverter operation, while the 100,000 BTU Wi-Fi model favors higher capacity and remote control.
- Gas heaters and heat pumps solve different problems: Raypak’s 105,000 BTU natural-gas models and Hayward’s 135,000 BTU propane model emphasize higher output, while electric heat pumps depend more on suitable outdoor conditions.
- Pool-volume claims need a careful match: several compact models specify gallon limits, but two listings describe pool dimensions instead, so buyers should confirm actual water volume and manufacturer compatibility before choosing.
- Special features change the use case, not just convenience: the Crosswind 40i adds cooling, Wi-Fi appears on selected heat pumps, and the Intex solar mat trades independent heating control for a simple solar approach.

More Details on Our Top Picks
TURBRO Beluga B50V 50,000 BTU Inverter Pool Heat Pump
The TURBRO Beluga B50V balances useful capacity with control for owners of above-ground pools up to 15,000 gallons. Its inverter compressor adjusts output rather than simply cycling at full power, which can help maintain steadier water temperatures, while the titanium heat exchanger suits saltwater setups. Wi-Fi control adds remote adjustments and scheduling. Compared with the smaller Raypak Crosswind 30i, the Beluga is better matched to larger pools; the Raypak takes up less space and serves pools up to 7,500 gallons. The tradeoff is a substantial, hardwired unit: professional electrical installation is required, and heating performance falls when outdoor temperatures drop below 60°F. It also needs separate hoses, valves, and filtration equipment, so buyers should plan for a complete installation rather than an all-in-one kit.
Pros:- Inverter output adjusts to help hold a steadier water temperature.
- Titanium heat exchanger is compatible with saltwater and seawater pools.
- Wi-Fi app supports remote control and timer settings.
- Rated for pools up to 15,000 gallons, more capacity than the Raypak Crosswind 30i.
Cons:- Requires a hardwired connection and professional electrical installation.
- Performance decreases when outdoor temperatures fall below 60°F.
- Hoses, valves, and pool filters are not included.
Best for: Owners of above-ground or spa pools up to 15,000 gallons who want inverter-based temperature control, Wi-Fi access, and saltwater compatibility.
Not ideal for: Inflatable-pool owners, buyers seeking a plug-in setup, or swimmers who need dependable heating in outdoor temperatures below 60°F.
- Heating capacity:50,000 BTU; up to 75,000 BTU peak
- Pool capacity:Up to 15,000 gallons
- Voltage:220–240 V
- Heat exchanger:Titanium
- Connectivity:Wi-Fi enabled
- Dimensions:25.9 x 15.7 x 38.5 inches
- Weight:146.7 pounds
- Model:B50V
Our verdict“Choose the Beluga B50V for a larger above-ground pool that needs efficient, app-controlled heating and can support a professionally installed heat pump.”
Swimming Pool Heater for Above Ground and Inground Pools – 20′ x 43′ x 48″ | 100,000 BTU Inverter Heat Pump with WiFi Control
For a buyer prioritizing substantial output and year-round temperature control, this 100,000 BTU inverter heat pump is the high-capacity choice in this group. It can heat or cool water across a stated range of 47°F to 104°F, a broader seasonal role than the heating-focused TURBRO Beluga B50V. Wi-Fi controls and a listed COP of 15.8 give owners remote scheduling and a way to compare energy performance, while the 55 dB operating figure points to quieter use than many conventional heater setups. The compromises are practical: at 116.8 pounds, it is not a casual lift, and its 220V supply and hose-size requirements call for installation planning. Its listed pool dimensions also do not replace checking actual gallons, plumbing, and circulation compatibility before purchase.
Pros:- 100,000 BTU output offers far more capacity than the Raypak Crosswind 30i.
- Heating and cooling modes support use across a wider range of seasons.
- Wi-Fi app control allows remote adjustments and scheduling.
- Listed 55 dB operation and COP of 15.8.
Cons:- The 116.8-pound unit may need professional help to position and install.
- Requires 220V power.
- Installation depends on compatible hose sizes and adapters.
Best for: Owners of larger above-ground or inground pools who want high heating output, app control, and a cooling mode for warm weather.
Not ideal for: Buyers with small pools, 110V-only electrical service, or plumbing that cannot accommodate the specified hose sizes and adapters.
- BTU output:100,000 BTU
- Voltage:220V
- Heating and cooling range:47°F to 104°F
- COP:15.8
- Noise level:55 dB
- Dimensions:39 x 17.32 x 25.6 inches
- Weight:116.8 pounds
- Model:HEX100
- Warranty:3 years
Our verdict“Pick this model when a large pool needs strong heat-pump capacity plus cooling, and the site can accommodate its 220V connection and plumbing requirements.”
Raypak Crosswind 30i 28,000 BTU Electric Pool and Spa Heat Pump
The Raypak Crosswind 30i is the more restrained choice for pools up to 7,500 gallons, with both heating and cooling in a compact, 59.9-pound package. Inverter operation is intended to adjust output around the selected temperature, and its titanium heat exchanger adds saltwater-friendly corrosion resistance. Compared with the TURBRO Beluga B50V, the Crosswind serves a much smaller pool and has substantially less stated heating capacity, but it weighs far less and takes up less width. That makes it a better fit when a large-capacity unit would be excessive. It is not a plug-in shortcut, though: hard wiring is required, and the 208/230V supply needs to suit the installation. Buyers seeking fast heating for a large above-ground pool should look instead at the 100,000 BTU HEX100.
Pros:- Compact design and lower weight than the TURBRO Beluga B50V.
- Provides both heating and cooling.
- Inverter technology adjusts operation around the selected temperature.
- Titanium heat exchanger and Wi-Fi connectivity.
Cons:- Capacity is limited to pools up to 7,500 gallons.
- Requires hard wiring; it is not a plug-in unit.
- 28,000 BTU output is modest compared with the HEX100.
Best for: Owners of above-ground pools or spas up to 7,500 gallons who want a compact, hardwired heat pump with heating and cooling.
Not ideal for: Owners of larger pools or anyone who needs a plug-in heater or higher output for rapid temperature changes.
- Heating capacity:28,000 BTU
- Pool capacity:Up to 7,500 gallons
- Voltage:208/230V
- Installation:Hard-wired; not plug-in
- Functions:Heating and cooling
- Heat exchanger:Titanium
- Connectivity:Wi-Fi
- Dimensions:39.02 x 13.39 x 25.87 inches
- Weight:59.9 pounds
Our verdict“Choose the Crosswind 30i for a smaller pool where compact size and dual-mode operation matter more than high heating capacity.”
Hayward W3H135FDP H-Series Propane Pool Heater, Beige, 135,000 BTU
The Hayward W3H135FDP is the lineup’s propane-fueled, high-output alternative, rated at 135,000 BTU for inground pools and spas. That makes it a different kind of choice from the heat pumps here: the Raypak Crosswind 30i is built around inverter operation and dual heating and cooling, while this Hayward focuses on propane heating for its stated application. Corrosion-resistant components suit outdoor pool environments, and its listed weight is lighter than several heat pumps in this roundup. But the application is the deciding limitation: the product data specifies inground pools and spas, not above-ground pools. I would not treat its high BTU figure as proof of compatibility with an above-ground setup. Buyers should confirm installation and fuel requirements for their pool before choosing it; above-ground owners may be better served by a model explicitly listed for their pool type.
Pros:- 135,000 BTU heating capacity.
- Propane fuel provides an alternative to the electric heat pumps in this roundup.
- Corrosion-resistant components are designed for outdoor pool environments.
- Listed weight is 27.3 pounds.
Cons:- Product data specifies inground pools and spas, not above-ground pools.
- Propane fuel requires a suitable supply and installation.
- Heating only; no cooling mode or listed Wi-Fi control.
Best for: Owners of inground pools or spas seeking a propane heater with substantial stated heating capacity.
Not ideal for: Above-ground pool owners, buyers without a propane supply, or anyone wanting cooling, Wi-Fi, or inverter heat-pump operation.
- Model:W3H135FDP
- Fuel type:Propane
- Heating capacity:135,000 BTU
- Application:Inground pools and spas
- Color:Beige
- Dimensions:21.5 x 30 x 22.5 inches
- Weight:27.3 pounds
- Manufacturer:Hayward
Our verdict“Consider the Hayward for an inground pool or spa with a propane setup, but skip it if you need a heater expressly suited to an above-ground pool.”
18,000 BTU Swimming Pool Heat Pump for Above Ground and Inground Pools up to 6,500 Gallons
This 18,000 BTU heat pump targets smaller pools, with a stated ceiling of 6,500 gallons and a 110V connection that may suit buyers who cannot accommodate the 208/230V hardwired Raypak Crosswind 30i. It also heats and cools, includes auto-defrost, and is listed at 38 dB—useful details for owners who want a quieter unit and more than a summer-only heater. Its 72-pound weight is still substantial for a compact model, so “easy installation” should not be read as effortless lifting. Capacity is the main tradeoff: it is not the choice for larger pools or rapid temperature changes, and its cooling range stops at 83°F. Compared with the TURBRO Beluga B50V, this model is a more accessible small-pool fit, but has far less capacity.
Pros:- 110V power requirement differs from the 208/230V Raypak Crosswind 30i.
- Heating and cooling modes extend seasonal use.
- 38 dB listed noise level is quiet compared with the HEX100’s 55 dB.
- Auto-defrost and included adapters support setup and cold-weather operation.
Cons:- Pool capacity is limited to 6,500 gallons.
- At 72 pounds, it may take two people to position.
- Cooling range is limited to 41–83°F.
Best for: Owners of pools up to 6,500 gallons who want a 110V heat pump with heating, cooling, and auto-defrost.
Not ideal for: Owners of larger pools, shoppers needing deep cooling in very hot climates, or anyone unable to position a 72-pound unit.
- Heating capacity:18,000 BTU
- Maximum pool size:6,500 gallons
- Voltage:110V
- COP:5.5
- Heating range:41–104°F
- Cooling range:41–83°F
- Noise level:38 dB
- Weight:72 pounds
- Warranty:3-year comprehensive warranty
Our verdict“Choose this model for a small pool when 110V power, quiet operation, and dual-mode use outweigh the limited capacity.”
NATURAQUELL 18,000 BTU Swimming Pool Heat Pump for Pools up to 5,200 Gallons
The NATURAQUELL is a good fit when an above-ground pool is modest in size and the owner wants active temperature control without switching to gas. Its 18,000 BTU inverter heat pump can heat or cool pools up to 5,200 gallons, while the stated COP of up to 4.1 offers an efficiency-focused alternative to gas models such as the Raypak 106A. Wi-Fi and touch-panel controls make adjustments more convenient than the Raypak’s analog dial. The titanium heat exchanger is designed to resist pool-water corrosion, and standard 110–120V power may suit some residential setups. The tradeoff is capacity: it is not the pick for larger pools, where the Raypak WeatherKing TWPH-6560 has far more output. Check electrical and pump-flow requirements before installation.
Pros:- Heats and cools, giving more seasonal control than a heating-only setup.
- Inverter operation and a stated COP of up to 4.1 support an efficiency-focused choice.
- Wi-Fi app and touch-panel controls allow remote or on-site adjustments.
- Titanium heat exchanger is designed for corrosion resistance.
Cons:- Recommended pool capacity is limited to 5,200 gallons.
- Electrical supply, breaker, and pump-flow requirements need to be checked before installation.
- At 73.8 pounds, it may take planning to position and connect.
Best for: Owners of above-ground pools up to 5,200 gallons who want app control and both heating and cooling on residential voltage.
Not ideal for: Owners of larger pools or buyers who cannot verify suitable electrical service, breaker capacity, and pump flow before installation.
- Heating and cooling capacity:18,000 BTU
- Recommended pool capacity:Up to 5,200 gallons
- COP:Up to 4.1
- Voltage:110–120V
- Controls:Wi-Fi app and touch panel
- Heat exchanger:Titanium
- Dimensions:16.65 x 15.35 x 17.21 inches
- Weight:73.8 pounds
- Warranty support:8 years
Our verdict“Choose the NATURAQUELL for a smaller above-ground pool if you want app-controlled heating and cooling without a natural-gas connection.”
Intex Solar Pool Water Heater Mat for Above-Ground Pools
The Intex solar mat is the simplest route in this group for buyers who want to use sunlight rather than a powered heat pump or gas burner. Its 11-square-foot UV-stabilized PVC surface circulates pool water for a stated temperature increase of about 5–9°F, though actual results depend on weather. That makes it a lower-complexity complement to a small above-ground pool, not a dependable substitute for the NATURAQUELL when heat needs to be controlled on cloudy days or cooling is desired. It supports pools up to 8,000 gallons, but the pump must stay within the listed flow and power limits. The mat’s foldable design helps with off-season storage; the tradeoff is modest, variable heating rather than the stronger, actively controlled output of the gas-fired Raypak 106A.
Pros:- Uses sunlight rather than gas or a dedicated heater power supply.
- Stated warming range is approximately 5–9°F, depending on conditions.
- Folds for compact winter storage.
- Includes a bypass valve and adapters for 1.25-inch and 1.5-inch hose connections.
Cons:- Heating performance depends on sunlight and weather.
- Requires a compatible pump rated up to 2,000 GPH and up to 1/3 HP.
- The small heating surface offers less active temperature control than powered heaters.
Best for: Above-ground pool owners in sunny locations who want a basic solar warming aid and have a compatible pump.
Not ideal for: Swimmers who need consistent temperature increases regardless of sun, or owners whose pump exceeds the mat’s flow or power limits.
- Model:28685E
- Heating surface area:11 square feet
- Water temperature increase:Approximately 5–9°F
- Maximum pool capacity:8,000 gallons
- Compatible pump flow rate:Up to 2,000 GPH
- Compatible pump power:Up to 1/3 HP
- Material:UV-stabilized PVC
- Dimensions:47.25 x 47.25 x 0.5 inches
- Weight:5.3 pounds
Our verdict“Pick the Intex mat if your priority is low-complexity solar warming and you can accept weather-dependent results.”
Raypak 106A 105,000 BTU Natural Gas Pool and Spa Heater
For an owner with a natural-gas connection who values straightforward controls, the Raypak 106A offers a different kind of heating setup from the electric heat pumps in this roundup. Its 105,000 BTU output is far higher than the NATURAQUELL’s 18,000 BTU, making the Raypak the more powerful choice for buyers who want gas-fired heating for an above-ground pool or spa. The analog thermostat keeps operation simple, while corrosion-resistant polymer headers and serviceable components are practical design features. The tradeoffs are equally clear: it runs on natural gas only, and the product is aimed at smaller pools and spas rather than larger swimming pools. Compared with the solar Intex mat, it offers active fuel-fired heating, but requires gas service and appropriate installation.
Pros:- 105,000 BTU natural-gas output offers substantially more heating capacity than the NATURAQUELL heat pump.
- Analog thermostat dial provides simple on-unit temperature setting.
- Corrosion-resistant polymer headers are designed for pool-heater use.
- Serviceable components can suit owners prioritizing repair access.
Cons:- Natural gas is the only listed fuel type.
- Intended for smaller pools and spas rather than larger pools.
- Product information lists conflicting dimensions, so installation clearance should be confirmed.
Best for: Owners of smaller above-ground pools or spas with natural-gas service who prefer a simple analog thermostat and serviceable components.
Not ideal for: Buyers without natural-gas access, owners of larger pools, or anyone seeking app-based controls or a solar-powered setup.
- Model:PR106AENC
- Heating capacity:105,000 BTU
- Fuel type:Natural gas
- Voltage:120V or 240V
- Thermostat:Analog dial
- Gas connection:1/2 in. NPT
- Headers:Corrosion-resistant polymer
- Weight:102 lbs
Our verdict“Choose the Raypak 106A if you have natural gas and need a higher-output, analog-controlled heater for a smaller pool or spa.”
Raypak PR106AENC 105,000 BTU Natural Gas Pool and Spa Heater
This Raypak PR106AENC suits above-ground pool owners who want a natural-gas heater with electronic ignition rather than the more basic operating approach of the Raypak 106A listing. Both offer 105,000 BTU and analog temperature controls, but this model’s pilot operates only while the heater is in use, and its listed elevation range is 0–4,999 feet. A single-piece extruded copper fin-tube heat exchanger and polymer headers distinguish its construction; the headers are designed to help avoid rust staining around the pool or spa. It remains a gas-only choice, so it cannot match the fuel flexibility of an electric heat pump such as the Raypak WeatherKing TWPH-6560. Buyers should also confirm elevation suitability and installation requirements before choosing it.
Pros:- Electronic ignition and a pilot that operates only while the heater is in use.
- 105,000 BTU capacity for above-ground pools and spas.
- Single-piece extruded copper fin-tube heat exchanger.
- Polymer headers are designed to help prevent rust stains on pool or spa surfaces.
Cons:- Natural gas only, unlike electric heat-pump options.
- Listed elevation range ends at 4,999 feet.
- Analog dial offers less control convenience than digital or Wi-Fi models.
Best for: Owners of above-ground pools or spas below 5,000 feet who have natural gas and want electronic ignition with an analog dial.
Not ideal for: Owners at elevations of 5,000 feet or higher, buyers without natural-gas service, or those wanting digital or app controls.
- Fuel type:Natural gas
- Heating capacity:105,000 BTU
- Intended use:Above-ground pools and spas
- Elevation range:0–4,999 ft
- Heat exchanger:Single-piece extruded copper fin-tube
- Ignition:Electronic
- Controls:Analog dial
- Dimensions:30 x 27 x 16 inches
- Weight:78.8 pounds
Our verdict“Choose this PR106AENC if your pool is within its elevation range and you want a natural-gas heater with electronic ignition.”
Raypak WeatherKing TWPH-6560 118,000 BTU Pool and Spa Heat Pump
The WeatherKing is the high-capacity heat-pump choice here, with 118,000 BTU and compatibility with both above-ground and in-ground pools. Compared with the NATURAQUELL’s 18,000 BTU output, it is intended for a much larger heating task, although the product data does not specify a pool-volume limit. Its titanium tube heat exchanger and scroll compressor are aimed at durable, quieter operation, while digital controls offer a more current interface than the analog dials on the two Raypak gas heaters. That broader capacity comes with a substantial footprint: at 38.75 inches square and 42.5 inches high, it needs dedicated space. It is a better match for buyers prioritizing heat-pump operation and larger pools than for owners of compact above-ground setups.
Pros:- 118,000 BTU output is the highest listed heat-pump capacity in this batch.
- Works with both above-ground and in-ground pools.
- Titanium tube heat exchanger is designed for pool-water service.
- Scroll compressor is designed for quiet operation, with digital controls for adjustments.
Cons:- Large 38.75 x 38.75 x 42.5-inch footprint requires substantial space.
- Product data does not state a recommended pool-volume limit.
- Warranty coverage differs by component, with two years of labor and seven years of parts.
Best for: Owners of larger above-ground or in-ground pools who want a high-capacity heat pump, digital controls, and titanium heat-exchanger construction.
Not ideal for: Owners with limited equipment-pad space or small above-ground pools that do not need 118,000 BTU of listed heating capacity.
- Model:TWPH-6560EHT01
- Heating capacity:118,000 BTU
- Pool compatibility:In-ground and above-ground pools
- Heat exchanger:Titanium tube
- Controls:Digital
- Compressor:Scroll
- Dimensions:38.75 x 38.75 x 42.5 inches
- Labor warranty:2 years
- Parts warranty:7 years
Our verdict“Choose the WeatherKing when you need a high-capacity heat pump and have room for its large outdoor footprint.”
Vidapool 75,000 BTU Electric Pool Heat Pump for Pools up to 21,000 Gallons
With a stated capacity of 75,000 BTU for pools up to 21,000 gallons, this Vidapool is the strongest fit here for owners with a larger above-ground setup. Its inverter control can reduce output as the water approaches the target temperature, while Wi-Fi scheduling makes routine adjustments easier than relying on manual controls. It also heats and cools, a useful pairing if you want temperature control beyond extending the swimming season. Compared with the smaller Varpoolfaye 30,000 BTU, it is built for substantially more water, but the tradeoff is a 220 V supply and a much heavier 214-pound body. The connection adapters offer flexibility for hose or PVC plumbing; still, plan for a pool cover in extreme conditions to help limit heat loss.
Pros:- 75,000 BTU capacity is suited to larger pools than the 30,000 BTU Varpoolfaye.
- Inverter control adjusts output as water approaches the set temperature.
- Wi-Fi app supports temperature changes and scheduling.
- Heating and cooling modes plus hose and PVC connection options offer setup flexibility.
Cons:- At 214 pounds, it is difficult to move into position.
- Requires a 220 V power supply.
- A pool cover is recommended in extreme temperatures to help retain heat.
Best for: Owners of larger above-ground pools, up to the stated 21,000-gallon limit, who want app scheduling and both heating and cooling.

Swimming Pool Heater for Above Ground and Inground Pools 12′ x 14′ x 48″
This 16,000 BTU heat pump takes a lower-capacity, quieter approach than the lineup’s larger units. Its 38 dB operating sound may suit a compact backyard where a louder heater would be distracting, and heating plus cooling gives owners a way to manage water temperature across more of the season. At 72 pounds, it is also far easier to position than the 214-pound Vidapool 75,000 BTU. The tradeoff is capacity: the provided specifications do not state a maximum pool volume, and the product is described primarily for above-ground pools, so I would not choose it for a large pool or assume it will perform similarly in an inground installation. Its 110 V supply and included adapters make setup approachable, but its 5.5 COP is below the 5.8 listed for the Varpoolfaye 30,000 BTU.
Pros:- 38 dB operating sound is quieter than the listed 52 dB Varpoolfaye.
- Heating and cooling modes support use across seasons.
- 110 V power and included hose adapters can simplify installation.
- At 72 pounds, it is lighter than the larger Vidapool and Varpoolfaye units.
Cons:- The 16,000 BTU rating is modest compared with larger-capacity options.
- No maximum pool volume is supplied in the provided specifications.
- The product is described primarily for above-ground pools, so inground performance may vary.
Best for: Owners of smaller above-ground pools who prioritize quiet operation, a 110 V supply, and both heating and cooling.
Not ideal for: Owners of large pools or buyers who need a clearly stated pool-capacity limit; the listed specifications provide no maximum gallon rating.
- Heating capacity:16,000 BTU
- Power supply:110 V
- COP:5.5
- Operating sound level:38 dB
- Weight:72 pounds
- Dimensions:21 x 19.5 x 19.5 inches
- Operating modes:Heating and cooling
- Model:HEX016
Our verdict“Pick this model for a smaller above-ground pool where low noise matters more than high heating capacity or a specified gallon limit.”
30,000 BTU Pool Heat Pump with Wi-Fi Control for Pools up to 7,000 Gallons
The titanium heat exchanger is the distinguishing reason to consider this 30,000 BTU model: it is specified for both freshwater and saltwater pools, giving saltwater owners a clear compatibility point to compare against other heaters. It also offers Wi-Fi control, heating and cooling, and a 5.8 COP, while its stated pool limit of 7,000 gallons makes the intended scale more concrete than the 16,000 BTU HEX016, which has no gallon capacity listed. That capacity is also its main boundary: buyers with larger pools should look to the 75,000 BTU Vidapool instead. At 115.8 pounds, this unit is not easy to move, and its 52 dB noise rating is higher than the HEX016’s 38 dB. The listing also notes condensation can emerge from the bottom during heat exchange and defrosting.
Pros:- Titanium heat exchanger is specified for freshwater and saltwater pools.
- 30,000 BTU capacity is matched to a stated limit of up to 7,000 gallons.
- Wi-Fi app supports temperature and schedule adjustments.
- Heating and cooling modes broaden its seasonal use.
Cons:- The 7,000-gallon limit rules it out for larger pools.
- At 52 dB, it is louder than the HEX016’s listed 38 dB.
- The unit weighs 115.8 pounds, and condensation may emerge from its bottom during operation.
Best for: Owners of freshwater or saltwater above-ground pools up to 7,000 gallons who want app control and heating and cooling modes.
Not ideal for: Owners of larger pools, noise-sensitive yards, or buyers who need a lightweight unit; its stated capacity is limited and it weighs 115.8 pounds.
- Maximum output:30,000 BTU
- Recommended pool capacity:Up to 7,000 gallons
- COP:5.8
- Power supply:110 V, 60 Hz
- Heat exchanger:Titanium
- Pool compatibility:Freshwater and saltwater
- Noise level:52 dB
- Weight:115.8 pounds
Our verdict“Choose this heat pump for a saltwater or freshwater pool within 7,000 gallons when app control matters, but look elsewhere for a larger or quieter setup.”
Raypak Crosswind 40i 33,000 BTU Electric Pool Heat Pump and Chiller
The Crosswind 40i suits buyers who want one hardwired heat pump for pool or spa heating and cooling, rather than a plug-in appliance for a straightforward above-ground setup. Its inverter technology adjusts output to maintain the set temperature, and the spiral titanium heat exchanger is designed to transfer heat to the water. The stated capacity is up to 9,000 gallons, placing it above the 7,000-gallon Varpoolfaye on paper, though below the much larger Vidapool’s 21,000-gallon limit. Raypak lists the heating output as 33,000 BTU in the title and 33,500 BTU in the description, so I would treat that figure as approximate. The LCD display is a direct control option rather than app-based convenience. Most importantly, hardwiring and a recommendation to consult a pool professional make installation more involved than the 110 V HEX016.
Pros:- Heats and cools pools and spas.
- Inverter technology adjusts output to maintain the set temperature.
- Spiral titanium heat exchanger is designed for heat transfer to pool water.
- Stated capacity reaches up to 9,000 gallons, more than the Varpoolfaye’s 7,000-gallon limit.

- Weight:124 pounds
Our verdict“Choose the Crosswind 40i if you need a hardwired pool-and-spa heater with cooling and professional installation, not if you want a plug-in setup.”
How We Picked
I compared these above-ground pool heaters by heating approach, stated BTU output, listed pool capacity or dimensions, and the practical demands each design places on the owner. I also looked at features that can change daily use—such as inverter operation, Wi-Fi control, cooling, and the choice of gas, electric heat pump, or solar heating—alongside fit and likely installation complexity. A larger BTU figure is not automatically a better choice: it only helps if the unit suits the pool, available fuel or power, and expected swimming conditions.
The ranking favors clearer matches between capacity and buyer needs, then separates picks by role rather than treating every heater as interchangeable. Models with more specific pool-size guidance are easier to evaluate for smaller pools; higher-output gas units suit buyers who prioritize heating power and have the right fuel setup. Where product listings provide limited sizing detail, I treat that as a reason for buyers to verify compatibility, not as proof the heater will fit any pool.

Factors to Consider When Choosing Above Ground Pool Heaters
Before choosing among these heaters, I’d work backward from the pool and the conditions where it sits. A heater that looks powerful on paper can disappoint if the pool’s water volume, electrical supply, fuel source, or local weather does not fit its requirements. These broader checks help avoid buying more capacity—or more installation work—than your setup can use.
Match heater capacity to actual water volume
Start with the pool’s actual water volume, not just its advertised diameter or footprint. Water depth changes the gallons substantially, and two pools with similar dimensions can have different heating loads. Compare the manufacturer’s stated pool-size guidance with your pool’s filled capacity, then ask whether the unit is intended for above-ground use and your plumbing arrangement. A high BTU rating does not replace a suitable capacity match; an undersized heater may struggle to reach your target, while an oversized choice can add cost and installation demands without solving other limits. If a listing gives dimensions instead of gallons, calculate the approximate volume and confirm the heater’s permitted pool range before ordering.
Choose the heating method around your climate and routine
Heat pumps, gas heaters, and solar mats behave differently, so the best fit depends on when and how you swim. Heat pumps draw warmth from outdoor air and generally make more sense where conditions support that process; cooler air can reduce their heating performance. Gas heaters can be a better fit when faster heat or more flexible operation matters, but they require the correct fuel connection and safe installation. Solar mats rely on available sunlight and are a modest approach rather than a dependable way to command a precise temperature on a set schedule. Think about whether you want to maintain warmth over many days or heat the pool for occasional use.
Check power, fuel, plumbing, and installation before buying
Installation compatibility can decide the purchase before heating capacity does. Confirm the heater’s electrical requirements or fuel type, the pool’s pump and flow needs, and the space available for safe placement and ventilation. A propane model is not a drop-in alternative to a natural-gas heater, and a gas connection may require qualified installation. Heat pumps also need suitable outdoor clearance and a compatible electrical circuit; Wi-Fi control does not remove those requirements. Check the manual and local rules before ordering, and include any needed plumbing fittings or professional work in your plan.
Account for weather, wind, and heat loss
A heater does not work alone: heat loss from the pool can erase gains, especially overnight or in windy conditions. A pool cover can help retain warmth and reduce the amount of work the heater must do, while placement out of strong wind can support more consistent operation. Owners in cooler areas should be realistic about how much a heat pump can raise water temperature and how long that may take. If your swimming schedule is occasional and weather varies, a cover and a practical temperature target may matter as much as moving to a higher BTU class. Compare expected season and local conditions, not only a best-case heating claim.
Decide which convenience features earn their keep
Wi-Fi, inverter operation, and cooling are useful only when they match how you use the pool. Remote controls can help owners adjust settings without visiting the equipment, while inverter designs can vary output rather than running at one fixed level. A heat-and-chill model offers a distinct benefit where summer water can become uncomfortably warm, but that feature may be unnecessary if your goal is heating alone. Solar heating has fewer control expectations, so it suits owners comfortable with sunlight-dependent results. I’d prioritize reliable size fit and installation compatibility first, then pay for added controls or modes that solve a real routine problem.
Compare total ownership demands, not just the heater
Plan for maintenance, operating needs, and seasonal care as part of the choice. Gas equipment needs attention to fuel connections and combustion safety, while heat pumps require clear airflow and routine care around their outdoor components. Solar mats need a suitable position and enough sun, and their output can vary with the weather. Check how the manufacturer describes winterizing, service access, warranty coverage, and required water flow before settling on a model. A heater that is easy to install but poorly matched to your climate or pool can be a worse long-term fit than one with a higher setup burden.
Frequently Asked Questions
How do I choose between a heat pump and a gas heater for an above-ground pool?
I’d base the decision on climate, swimming schedule, and available connections rather than BTU figures alone. Heat pumps draw warmth from outdoor air, so their performance depends on suitable conditions and they may be less effective in colder weather. Gas heaters use propane or natural gas and can suit buyers who want higher output or more flexible heating, but the fuel supply and installation must match the model. If you swim regularly in a mild climate, a heat pump may fit your routine; for occasional heating or cooler conditions, compare gas options and the full installation requirements.
Can I use a heater listed for both above-ground and inground pools with my pool?
Possibly, but the broad label does not confirm that the heater fits your specific pool or equipment. Check the unit’s permitted water volume, required flow rate, plumbing connections, and electrical or fuel needs against your setup. Above-ground pools can have different pump and hose arrangements from permanent inground systems, so compatibility should be confirmed in the manufacturer’s instructions. Also verify whether any fittings or bypass components are required. If a listing gives pool dimensions rather than gallons, calculate the filled volume and ask the manufacturer to confirm the match.
Will a 50,000 BTU heater warm my pool faster than an 18,000 BTU model?
Greater stated output can provide more heating capacity, but it does not by itself predict the time needed to warm your pool. Water volume, starting temperature, outdoor conditions, wind, and heat loss all affect results. The 18,000 BTU models in this lineup are specified for smaller pools, while the 50,000 BTU TURBRO is a different capacity class; choosing based on a number alone could lead to a poor fit. Compare the heater’s stated pool range with your actual gallons, and use a cover to reduce heat loss when practical. Ask the maker for expected performance under conditions similar to yours.
Is a solar pool heater mat enough to heat an above-ground pool?
A solar mat can contribute heat when it receives adequate sunlight, but its output is weather-dependent and offers less control than a powered heater. It is a better match for owners with a small pool, a sunny location, and flexible expectations than for someone who needs a specific temperature on a set date. Shade, cloudy spells, and cool nights can limit the benefit. Check the mat’s pool and pump compatibility, along with the manufacturer’s guidance on how many mats may be needed. A pool cover can help retain the warmth it adds.
What should I verify before ordering a Wi-Fi pool heat pump?
First verify the pool-size range, required electrical supply, water-flow requirements, and outdoor placement rules; remote control cannot compensate for a mismatch in those basics. Check whether the Wi-Fi feature works with your home network and whether the app offers the controls you actually want. Confirm that the heat pump is approved for your pool type and plumbing setup, and review installation and winterizing instructions. If the listing gives dimensions rather than gallon capacity, confirm the unit’s intended pool volume with the manufacturer. I’d treat connectivity as a convenience feature, not a substitute for a suitable heater.
Conclusion
For a balanced choice, I’d recommend the TURBRO Beluga B50V as best overall: its 50,000 BTU inverter design sits between the compact heat pumps and the higher-output equipment. The 18,000 BTU Swimming Pool Heat Pump for pools up to 6,500 gallons is my value-oriented pick for a smaller pool that fits its stated range; the NATURAQUELL is another compact option with a lower listed pool limit of 5,200 gallons. For a premium, higher-capacity direction, compare the 100,000 BTU Wi-Fi heat pump with Raypak’s natural-gas models and Hayward’s propane heater, choosing by climate, fuel access, and pool volume rather than output alone. Beginners may prefer the Intex solar mat only if they are comfortable with sunlight-dependent heating and modest control. For a specific need, the Raypak Crosswind 40i is the standout for buyers seeking both heating and cooling. Before choosing any model, confirm the pool’s gallons, connections, and installation requirements.
