In-ground models run on 240V single-phase power with a 15-amp maximum breaker and 5.5 circuit amps. The 135K BTU above-ground models use 120V. Clearance requirements are 6 inches rear and 12 inches on each side. In-ground units connect via 2\" x 2-1\/2\" CPVC union fittings, which makes replacement on an existing equipment pad straightforward. All models use a cupro nickel heat exchanger and low NOx combustion, and none require a high-wind stack for outdoor installation.\u003c\/p\u003e\n\n\u003ch2\u003eChoosing the Right BTU for Your Pool\u003c\/h2\u003e\n\u003cp\u003eGas heater BTU sizing is primarily about recovery speed - how fast the heater can bring a cold pool up to temperature - rather than whether it can heat the pool at all.

The units are identical in output, dimensions, electrical requirements, and warranty - the only difference is fuel type, and the two are not field-interchangeable without a licensed conversion. Natural gas is generally cheaper to run per BTU in most US markets, so if your home or property already has a natural gas line, that is the lower-cost choice over time. Propane makes sense when natural gas is not available at the installation site.\u003c\/p\u003e\n\n\u003ch2\u003ePool Gas Heater vs. Heat Pump - What Is the Right Fit?\u003c\/h2\u003e\n\u003cp\u003eGas heaters heat water faster than heat pumps and maintain full output regardless of air temperature. That makes them the better choice for pools that sit unused for long periods, pools in cold climates, spas that need fast recovery, or any setup where time-to-temperature matters more than energy cost. Heat pumps move heat from the air rather than burning fuel, which makes them significantly more efficient in moderate climates for day-to-day temperature maintenance. For Florida pools used regularly through a long swim season, a heat pump often has lower operating costs. For large pools, spas, or pools in colder regions, a gas heater - or a gas heater paired with a heat pump - is usually the better fit.

It delivers 135,000 BTU\/hr of heating output, operates in low ambient temperatures down to 40 degrees F, and uses a cupro nickel heat exchanger built to handle demanding pool water conditions. At 100 lb and 21.4\" wide, it is the most compact model in the H-Series natural gas lineup - easy to position and straightforward to service.\u003c\/p\u003e\n\n\u003ch2\u003eW3H135FDN H-Series Above-Ground Natural Gas Pool Heater - Specs and Features\u003c\/h2\u003e\n\u003cp\u003eThe W3H135FDN runs on 120V single-phase, 60 Hz power and draws 5.5 circuit amps with a 15-amp maximum breaker. This model is 120V only - it does not have the field-conversion option found on the larger in-ground Universal H-Series models. It supports water flow between 20 and 125 GPM and uses an induced draft combustion design. The cabinet measures 22.6\" H x 21.4\" W x 30.3\" L and weighs 100 lb.\u003c\/p\u003e\n\n\u003ch3\u003eW3H135FDN Installation and Clearance Requirements\u003c\/h3\u003e\n\u003cp\u003eThe W3H135FDN requires 6 inches of rear clearance and 12 inches on each side. The induced draft system controls combustion airflow internally, so no high-wind stack is required for outdoor installations. Before setting the unit, confirm your natural gas meter capacity and supply line sizing are sufficient - undersized piping or a low-capacity meter will cause startup and performance problems regardless of how well everything else is installed. This model is designed for outdoor above-ground pool installations; confirm local code requirements for any semi-enclosed equipment areas.\u003c\/p\u003e\n\n\u003ch2\u003eH-Series Combustion System and Pool Sizing\u003c\/h2\u003e\n\u003cp\u003eThe W3H135FDN uses an induced draft design that moves combustion air through the chamber at a controlled rate, keeping heat output consistent across varying outdoor conditions. Hayward's hydraulic design maintains uniform water velocity across all heat exchanger tubes, which produces faster heat-up times and reduced pump run time. At 135,000 BTU\/hr, this unit is well matched for above-ground pools in the 5,000 to 15,000 gallon range and spas where fast warm-up is the priority. It can handle up to around 25,000 gallons in warm climates where heat loss is minimal, but the sweet spot is smaller water volumes where it heats quickly and efficiently.

It delivers 135,000 BTU\/hr of heating output, operates in low ambient temperatures down to 40 degrees F, and uses a cupro nickel heat exchanger built to handle demanding pool water conditions. At 100 lb and 21.4\" wide, it is the most compact model in the H-Series propane lineup - easy to position and straightforward to service.\u003c\/p\u003e\n\n\u003ch2\u003eW3H135FDP H-Series Above-Ground Propane Pool Heater - Specs and Features\u003c\/h2\u003e\n\u003cp\u003eThe W3H135FDP runs on 120V single-phase, 60 Hz power and draws 5.5 circuit amps with a 15-amp maximum breaker. Unlike the larger in-ground H-Series models, this unit is 120V only - no field conversion to 240V. It supports water flow between 20 and 125 GPM and uses an induced draft combustion design. The cabinet measures 22.6\" H x 21.4\" W x 30.3\" L and weighs 100 lb.\u003c\/p\u003e\n\n\u003ch3\u003eW3H135FDP Installation and Clearance Requirements\u003c\/h3\u003e\n\u003cp\u003eThe W3H135FDP requires 6 inches of rear clearance and 12 inches on each side. The induced draft system controls combustion airflow internally, so no high-wind stack is required for outdoor installations. Before setting the unit, confirm your propane supply line sizing and regulator output match the fuel requirements - undersized supply lines will cause startup and performance problems regardless of how well everything else is installed. This model is designed for outdoor above-ground pool installations; confirm local code requirements for any semi-enclosed equipment areas.\u003c\/p\u003e\n\n\u003ch2\u003eH-Series Combustion System and Pool Sizing\u003c\/h2\u003e\n\u003cp\u003eThe W3H135FDP uses an induced draft design that moves combustion air through the chamber at a controlled rate, keeping heat output consistent across varying outdoor conditions. Hayward's hydraulic design maintains uniform water velocity across all heat exchanger tubes, which produces faster heat-up times and reduced pump run time. At 135,000 BTU\/hr, this unit is well matched for above-ground pools in the 5,000 to 15,000 gallon range and spas where fast warm-up is the priority. It can handle up to around 25,000 gallons in warm climates where heat loss is minimal, but the sweet spot is smaller water volumes where it heats quickly and efficiently.\u003c\/p\u003e\n\n\u003ch3\u003eCupro Nickel Heat Exchanger and Water Chemistry Durability\u003c\/h3\u003e\n\u003cp\u003eThe W3H135FDP uses a cupro nickel heat exchanger with Hayward's managed water flow design, which keeps the same water velocity through all tubes for consistent heat transfer. Cupro nickel handles salt water and aggressive pool chemistry better than standard copper alternatives - a meaningful spec even on above-ground pools running salt systems or higher sanitizer levels. Heat exchanger corrosion is one of the more common long-term failure points on gas heaters, so the material choice matters regardless of pool type.\u003c\/p\u003e\n\n\u003ch3\u003eW3H135FDP vs. In-Ground H-Series Models - Key Differences\u003c\/h3\u003e\n\u003cp\u003eThe W3H135FDP is purpose-built for above-ground pools and differs from the in-ground Universal H-Series line in a few important ways.

It delivers 150,000 BTU\/hr of heating output, operates in low ambient temperatures down to 40 degrees F, and connects via 2\" x 2-1\/2\" CPVC union fittings that simplify new installs and replacement jobs. The forced-draft combustion system and low NOx design also qualify it for use in stricter air quality regions including SCAQMD Rule 1146.2 jurisdictions.\u003c\/p\u003e\n\u003ch2\u003eW3H150FDN Universal H-Series Natural Gas Pool Heater - Specs and Features\u003c\/h2\u003e\n\u003cp\u003eThe W3H150FDN ships factory-wired for 240V single-phase, 60 Hz power but can be field-converted to 120V by swapping a jumper on the ignition control board. It draws only 5.5 circuit amps with a 15-amp maximum breaker - a minimal electrical footprint for any gas heater. It supports water flow between 20 and 125 GPM and uses a cupro nickel heat exchanger rated for salt water and chemically demanding pool environments. At 135 lb and 19\" wide, it is the smallest and lightest model in the Universal H-Series natural gas lineup - a practical advantage on tight equipment pads and straightforward replacement jobs.\u003c\/p\u003e\n\u003ch3\u003eW3H150FDN Installation and Clearance Requirements\u003c\/h3\u003e\n\u003cp\u003eThe W3H150FDN requires 6 inches of rear clearance and 12 inches on each side. The forced-draft design eliminates the need for a high-wind stack, which simplifies positioning in enclosed or semi-enclosed equipment areas. Plumbing connects via 2\" x 2-1\/2\" CPVC union fittings. Before setting the pad, confirm your natural gas meter capacity and supply line sizing are sufficient - undersized piping or a low-capacity meter will cause startup and performance issues regardless of how well everything else is installed.\u003c\/p\u003e\n\u003ch2\u003eUniversal H-Series Combustion System and Pool Sizing\u003c\/h2\u003e\n\u003cp\u003eThe Universal H-Series platform uses a forced-draft combustion design that pushes air through the chamber at a controlled rate regardless of wind conditions. That removes stack dependency and keeps combustion consistent across installation environments. Hayward's hydraulic design maintains uniform water velocity across all heat exchanger tubes, which produces faster heat-up times and reduced pump run time - Hayward rates that efficiency advantage at up to 18% compared with less efficient gas heater designs. At 150,000 BTU\/hr, this unit is well matched for pools in the 10,000 to 35,000 gallon range, with the upper end being most realistic in warmer climates where the pool holds heat well.

It draws only 5.5 circuit amps with a 15-amp maximum breaker - a minimal electrical footprint for any gas heater. It supports water flow between 20 and 125 GPM and uses a cupro nickel heat exchanger rated for salt water and chemically demanding pool environments. At 135 lb and 19\" wide, it is the smallest and lightest model in the Universal H-Series propane lineup - a practical advantage on tight equipment pads and straightforward replacement jobs.\u003c\/p\u003e\n\u003ch3\u003eW3H150FDP Installation and Clearance Requirements\u003c\/h3\u003e\n\u003cp\u003eThe W3H150FDP requires 6 inches of rear clearance and 12 inches on each side. The forced-draft design eliminates the need for a high-wind stack, which simplifies positioning in enclosed or semi-enclosed equipment areas. Plumbing connects via 2\" x 2-1\/2\" CPVC union fittings. Before setting the pad, confirm your propane supply line sizing and regulator output match the unit's fuel requirements - undersized supply lines will cause startup and performance issues regardless of how well everything else is installed.\u003c\/p\u003e\n\u003ch2\u003eUniversal H-Series Combustion System and Pool Sizing\u003c\/h2\u003e\n\u003cp\u003eThe Universal H-Series platform uses a forced-draft combustion design that pushes air through the chamber at a controlled rate regardless of wind conditions. That removes stack dependency and keeps combustion consistent across installation environments. Hayward's hydraulic design maintains uniform water velocity across all heat exchanger tubes, which produces faster heat-up times and reduced pump run time - Hayward rates that efficiency advantage at up to 18% compared with less efficient gas heater designs. At 150,000 BTU\/hr, this unit is well matched for pools in the 10,000 to 35,000 gallon range, with the upper end being most realistic in warmer climates where the pool holds heat well.

It draws only 5.5 circuit amps with a 15-amp maximum breaker - a minimal electrical footprint for a 200K BTU unit. It supports water flow between 20 and 125 GPM and uses a cupro nickel heat exchanger rated for salt water and chemically demanding pool environments. The cabinet measures 24\" H x 22\" W x 29.5\" L and weighs 140 lb - the most compact and lightest model in the Universal H-Series natural gas lineup, which makes it easy to work with on tight equipment pads and replacement jobs.\u003c\/p\u003e\n\n\u003ch3\u003eW3H200FDN Installation and Clearance Requirements\u003c\/h3\u003e\n\u003cp\u003eThe W3H200FDN requires 6 inches of rear clearance and 12 inches on each side. The forced-draft design eliminates the need for a high-wind stack, which simplifies positioning in enclosed or semi-enclosed equipment areas. Plumbing connects via 2\" x 2-1\/2\" CPVC union fittings. Before setting the pad, confirm your natural gas meter capacity and supply line sizing are sufficient - a 200K BTU heater draws meaningful gas volume, and undersized piping or a low-capacity meter will cause startup and performance issues.\u003c\/p\u003e\n\n\u003ch2\u003eUniversal H-Series Combustion System and Pool Sizing\u003c\/h2\u003e\n\u003cp\u003eThe Universal H-Series platform uses a forced-draft combustion design that pushes air through the chamber at a controlled rate regardless of wind conditions. That removes stack dependency and keeps combustion consistent across installation environments. Hayward's hydraulic design maintains uniform water velocity across all heat exchanger tubes, which produces faster heat-up times and reduced pump run time - Hayward rates that efficiency advantage at up to 18% compared with less efficient gas heater designs. At 200,000 BTU\/hr, this unit is well matched for pools in the 15,000 to 45,000 gallon range, with the upper end being most realistic in warmer climates where the pool holds heat well.

It draws only 5.5 circuit amps with a 15-amp maximum breaker - a minimal electrical footprint for a 200K BTU unit. It supports water flow between 20 and 125 GPM and uses a cupro nickel heat exchanger rated for salt water and chemically demanding pool environments. The cabinet measures 24\" H x 22\" W x 29.5\" L and weighs 140 lb - the most compact and lightest model in the Universal H-Series propane lineup, which makes it easy to work with on tight equipment pads and replacement jobs.\u003c\/p\u003e\n\n\u003ch3\u003eW3H200FDP Installation and Clearance Requirements\u003c\/h3\u003e\n\u003cp\u003eThe W3H200FDP requires 6 inches of rear clearance and 12 inches on each side. The forced-draft design eliminates the need for a high-wind stack, which simplifies positioning in enclosed or semi-enclosed equipment areas. Plumbing connects via 2\" x 2-1\/2\" CPVC union fittings. Before setting the pad, confirm your propane supply line sizing and regulator output match the unit's fuel requirements - undersized supply lines will cause startup and performance issues regardless of how well everything else is installed.\u003c\/p\u003e\n\n\u003ch2\u003eUniversal H-Series Combustion System and Pool Sizing\u003c\/h2\u003e\n\u003cp\u003eThe Universal H-Series platform uses a forced-draft combustion design that pushes air through the chamber at a controlled rate regardless of wind conditions. That removes stack dependency and keeps combustion consistent across installation environments. Hayward's hydraulic design maintains uniform water velocity across all heat exchanger tubes, which produces faster heat-up times and reduced pump run time - Hayward rates that efficiency advantage at up to 18% compared with less efficient gas heater designs. At 200,000 BTU\/hr, this unit is well matched for pools in the 15,000 to 45,000 gallon range, with the upper end being most realistic in warmer climates where the pool holds heat well.

It draws only 5.5 circuit amps with a 15-amp maximum breaker - a minimal electrical footprint for a 250K BTU unit. It supports water flow between 25 and 125 GPM and uses a cupro nickel heat exchanger rated for salt water and chemically demanding pool environments. The cabinet measures 24\" H x 25\" W x 29.5\" L and weighs 165 lb - noticeably lighter and narrower than the 400K BTU model, which helps on tighter equipment pads.\u003c\/p\u003e\n\n\u003ch3\u003eW3H250FDN Installation and Clearance Requirements\u003c\/h3\u003e\n\u003cp\u003eThe W3H250FDN requires 6 inches of rear clearance and 12 inches on each side. The forced-draft design eliminates the need for a high-wind stack, which simplifies positioning in enclosed or semi-enclosed equipment areas. Plumbing connects via 2\" x 2-1\/2\" CPVC union fittings. Before setting the pad, confirm your natural gas meter capacity and supply line sizing are sufficient - a 250K BTU heater draws significant gas volume, and undersized piping or a low-capacity meter will cause performance problems at startup.\u003c\/p\u003e\n\n\u003ch2\u003eUniversal H-Series Combustion System and Pool Sizing\u003c\/h2\u003e\n\u003cp\u003eThe Universal H-Series platform uses a forced-draft combustion design that pushes air through the chamber at a controlled rate regardless of wind conditions. That removes stack dependency and keeps combustion consistent across installation environments. Hayward's hydraulic design maintains uniform water velocity across all heat exchanger tubes, which produces faster heat-up times and reduced pump run time - Hayward rates that advantage at up to 18% compared with less efficient gas heater designs. At 250,000 BTU\/hr, this unit is well matched for pools in the 20,000 to 50,000 gallon range in moderate climates, with longer heat-up times on the larger end.\u003c\/p\u003e\n\n\u003ch3\u003eCupro Nickel Heat Exchanger and Salt Water Resistance\u003c\/h3\u003e\n\u003cp\u003eThe W3H250FDN uses a standard cupro nickel heat exchanger, which handles salt water and aggressive pool chemistry better than standard copper alternatives.

It delivers 250,000 BTU\/hr of heating output, operates in low ambient temperatures down to 40 degrees F, and connects via 2\" x 2-1\/2\" CPVC union fittings that simplify new installs and replacement jobs.

It draws only 5.5 circuit amps with a 15-amp maximum breaker - a minimal electrical footprint for a 250K BTU unit. It supports water flow between 25 and 125 GPM and uses a cupro nickel heat exchanger rated for salt water and chemically demanding pool environments. The cabinet measures 24\" H x 25\" W x 29.5\" L and weighs 165 lb - noticeably lighter and narrower than the 400K BTU model, which helps on tighter equipment pads.\u003c\/p\u003e\n\n\u003ch3\u003eW3H250FDP Installation and Clearance Requirements\u003c\/h3\u003e\n\u003cp\u003eThe W3H250FDP requires 6 inches of rear clearance and 12 inches on each side. The forced-draft design eliminates the need for a high-wind stack, which simplifies positioning in enclosed or semi-enclosed equipment areas. Plumbing connects via 2\" x 2-1\/2\" CPVC union fittings. Before setting the pad, confirm your propane supply line sizing and regulator output match the unit's fuel requirements - gas heaters are sensitive to inlet pressure, and undersized supply lines will cause startup and performance issues.\u003c\/p\u003e\n\n\u003ch2\u003eUniversal H-Series Combustion System and Pool Sizing\u003c\/h2\u003e\n\u003cp\u003eThe Universal H-Series platform uses a forced-draft combustion design that pushes air through the chamber at a controlled rate regardless of wind conditions. That removes stack dependency and keeps combustion consistent across installation environments. Hayward's hydraulic design maintains uniform water velocity across all heat exchanger tubes, which produces faster heat-up times and reduced pump run time - Hayward rates that advantage at up to 18% compared with less efficient gas heater designs. At 250,000 BTU\/hr, this unit is well matched for pools in the 20,000 to 50,000 gallon range in moderate climates, with longer heat-up times on the larger end.\u003c\/p\u003e\n\n\u003ch3\u003eCupro Nickel Heat Exchanger and Salt Water Resistance\u003c\/h3\u003e\n\u003cp\u003eThe W3H250FDP uses a standard cupro nickel heat exchanger, which handles salt water and aggressive pool chemistry better than standard copper alternatives.

It delivers 400,000 BTU\/hr of heating output, operates in low ambient temperatures down to 40 degrees F, and connects via 2\" x 2-1\/2\" CPVC union fittings that simplify replacement and retrofit installs.

It draws only 5.5 circuit amps with a 15-amp maximum breaker - a minimal electrical footprint for a 400K BTU unit. It supports water flow between 30 and 125 GPM and uses a cupro nickel heat exchanger rated for salt water and chemically demanding pool environments. The cabinet measures 24\" H x 34\" W x 29.5\" L and weighs 195 lb.\u003c\/p\u003e\n\u003ch3\u003eW3H400FDN Installation and Clearance Requirements\u003c\/h3\u003e\n\u003cp\u003eThe W3H400FDN requires 6 inches of rear clearance and 12 inches on each side. The forced-draft design eliminates the need for a high-wind stack, which simplifies positioning on tight equipment pads. Plumbing connects via 2\" x 2-1\/2\" CPVC union fittings. Before setting the pad, confirm your natural gas meter capacity and supply line sizing are sufficient - a 400K BTU heater draws significant gas volume, and undersized piping or a low-capacity meter will cause performance problems at startup.\u003c\/p\u003e\n\u003ch2\u003eUniversal H-Series Combustion System and Efficiency\u003c\/h2\u003e\n\u003cp\u003eThe Universal H-Series platform uses a forced-draft combustion design that pushes air through the chamber at a controlled rate regardless of wind conditions. That removes stack dependency and keeps combustion consistent across installation environments. Hayward's hydraulic design maintains uniform water velocity across all heat exchanger tubes, which produces faster heat-up times and reduces pump run time. Hayward rates the efficiency advantage at up to 18% compared with less efficient gas heater designs.\u003c\/p\u003e\n\u003ch3\u003eCupro Nickel Heat Exchanger and Chemical Resistance\u003c\/h3\u003e\n\u003cp\u003eThe W3H400FDN uses a standard cupro nickel heat exchanger, which handles salt water and aggressive pool chemistry better than standard copper alternatives. For pools running salt chlorine generators or elevated sanitizer levels, this is a meaningful spec - heat exchanger corrosion is one of the more common failure points on gas heaters over time. The cupro nickel material also holds up well in coastal installs where airborne salt adds to the chemical load on the unit.\u003c\/p\u003e\n\u003ch3\u003eW3H400FDN Natural Gas Heater vs. Heat Pump - Which Is Right for Your Pool?\u003c\/h3\u003e\n\u003cp\u003eGas heaters like the W3H400FDN heat water faster than heat pumps and maintain full output regardless of air temperature. That makes them the better choice for pools that sit unused for long stretches and need to heat up quickly, or for year-round pools in cold climates where heat pump efficiency drops off. The tradeoff is operating cost: natural gas burns continuously during use, while heat pumps move heat from the air and use far less energy per BTU delivered in moderate weather. Natural gas is generally cheaper to run than propane, which gives the W3H400FDN a cost advantage over the LP version in most markets. For pools in mild climates used regularly, a heat pump handles day-to-day heating more efficiently - but for large pools, spas, or any setup where fast recovery matters more than efficiency, a 400K BTU gas heater is hard to beat.\u003c\/p\u003e\n\u003ctable\u003e\n\u003ccaption\u003e\u003cstrong\u003eFull Specifications - Hayward W3H400FDN Natural Gas Pool Heater\u003c\/strong\u003e\u003c\/caption\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003cth\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eHayward\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eModel \/ SKU\u003c\/td\u003e\n\u003ctd\u003eW3H400FDN\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSeries\u003c\/td\u003e\n\u003ctd\u003eUniversal H-Series\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFuel Type\u003c\/td\u003e\n\u003ctd\u003eNatural Gas\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eApplication\u003c\/td\u003e\n\u003ctd\u003eNew Construction, Renovation\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePool Type\u003c\/td\u003e\n\u003ctd\u003eIn Ground\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHeating Capacity\u003c\/td\u003e\n\u003ctd\u003e400,000 BTU\/hr\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eKilowatts\u003c\/td\u003e\n\u003ctd\u003e117 kW\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHeat Exchanger\u003c\/td\u003e\n\u003ctd\u003eStandard cupro nickel\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLow NOx\u003c\/td\u003e\n\u003ctd\u003eYes\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCooling Capability\u003c\/td\u003e\n\u003ctd\u003eNo\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLow Ambient Operation\u003c\/td\u003e\n\u003ctd\u003eYes\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMinimum Operating Temperature\u003c\/td\u003e\n\u003ctd\u003e40 degrees F\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eVoltage\u003c\/td\u003e\n\u003ctd\u003e120\/240V (ships 240V; field-convertible to 120V)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePhase\u003c\/td\u003e\n\u003ctd\u003eSingle\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFrequency\u003c\/td\u003e\n\u003ctd\u003e60 Hz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCircuit Amps\u003c\/td\u003e\n\u003ctd\u003e5.5\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaximum Breaker Size\u003c\/td\u003e\n\u003ctd\u003e15 Amps\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWater Flow Rate\u003c\/td\u003e\n\u003ctd\u003e30 to 125 GPM\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePlumbing Connections\u003c\/td\u003e\n\u003ctd\u003e2\" x 2-1\/2\" CPVC union\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRear Clearance\u003c\/td\u003e\n\u003ctd\u003e6\"\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSide Clearance\u003c\/td\u003e\n\u003ctd\u003e12\"\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Dimensions (H x W x L)\u003c\/td\u003e\n\u003ctd\u003e24\" x 34\" x 29.5\"\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Weight\u003c\/td\u003e\n\u003ctd\u003e195 lb\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eShipping Dimensions\u003c\/td\u003e\n\u003ctd\u003e30.6\" x 32.8\" x 39.6\"\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eShipping Weight\u003c\/td\u003e\n\u003ctd\u003e214 lb\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRefrigerant\u003c\/td\u003e\n\u003ctd\u003eNo\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eActive Defrost\u003c\/td\u003e\n\u003ctd\u003eNo\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBoost Mode\u003c\/td\u003e\n\u003ctd\u003eNo\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSilent Mode\u003c\/td\u003e\n\u003ctd\u003eNo\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eChannel\u003c\/td\u003e\n\u003ctd\u003eOpen Line\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eGTIN\u003c\/td\u003e\n\u003ctd\u003e610377387255\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003cdetails\u003e\n\u003csummary\u003eIs this heater natural gas or propane?\u003c\/summary\u003e\n\u003cp\u003eNatural gas.

It delivers 400,000 BTU\/hr of heating output, runs on low ambient temperatures down to 40 degrees F, and connects via 2\" x 2-1\/2\" CPVC union fittings that make replacement and retrofit installs straightforward. The forced-draft combustion system and low NOx design also qualify it for use in stricter air quality regions including SCAQMD Rule 1146.2 jurisdictions.\u003c\/p\u003e\n\u003ch2\u003eW3H400FDP Universal H-Series Gas Pool Heater - Specs and Features\u003c\/h2\u003e\n\u003cp\u003eThe W3H400FDP runs on 120\/240V single-phase, 60 Hz power and draws only 5.5 circuit amps with a 15-amp maximum breaker - a minimal electrical footprint for a 400K BTU unit. It supports water flow between 30 and 125 GPM and uses a cupro nickel heat exchanger rated for salt water and chemically demanding pool environments.

There is no vertical clearance listed, but the forced-draft design eliminates the need for a high-wind stack, which simplifies positioning on tight equipment pads. Plumbing connects via 2\" x 2-1\/2\" CPVC union fittings. Confirm your propane supply line sizing and regulator output match the unit's fuel requirements before setting the pad - gas heaters are sensitive to inlet pressure in ways that heat pumps are not.\u003c\/p\u003e\n\u003ch2\u003eUniversal H-Series Combustion System and Efficiency\u003c\/h2\u003e\n\u003cp\u003eThe Universal H-Series platform uses a forced-draft combustion design that pushes air through the chamber at a controlled rate regardless of wind conditions. That removes stack dependency and keeps combustion consistent across installation environments. Hayward's hydraulic design also maintains uniform water velocity across all heat exchanger tubes, which translates to faster heat-up times and reduced pump run time. Hayward rates the efficiency advantage at up to 18% compared with less efficient gas heater designs.\u003c\/p\u003e\n\u003ch3\u003eCupro Nickel Heat Exchanger and Chemical Resistance\u003c\/h3\u003e\n\u003cp\u003eThe W3H400FDP uses a standard cupro nickel heat exchanger, which handles salt water and aggressive pool chemistry better than standard copper alternatives. For pools running salt chlorine generators or elevated sanitizer levels, this is a meaningful spec - heat exchanger corrosion is one of the more common failure points on gas heaters over time. The cupro nickel material also holds up well in coastal installs where airborne salt adds to the chemical load on the unit.\u003c\/p\u003e\n\u003ch3\u003eW3H400FDP Propane Gas Heater vs. Heat Pump - Which Is Right for Your Pool?\u003c\/h3\u003e\n\u003cp\u003eGas heaters like the W3H400FDP heat water faster than heat pumps and maintain full output regardless of air temperature. That makes them the better choice for pools that sit unused for long stretches and need to heat up quickly, or for year-round pools in cold climates where heat pump efficiency drops off. The tradeoff is operating cost: propane burns continuously during use, while heat pumps move heat from the air and use far less energy per BTU delivered in moderate weather. For pools in Florida or similarly warm climates, a heat pump handles day-to-day heating more cheaply, and a gas heater like this one is best used as a primary heater for large pools, spas, or any setup where fast recovery matters more than efficiency.\u003c\/p\u003e\n\u003ctable\u003e\n\u003ccaption\u003e\u003cstrong\u003eFull Specifications - Hayward W3H400FDP Propane Pool Heater\u003c\/strong\u003e\u003c\/caption\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003cth\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eHayward\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eModel \/ SKU\u003c\/td\u003e\n\u003ctd\u003eW3H400FDP\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSeries\u003c\/td\u003e\n\u003ctd\u003eUniversal H-Series\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFuel Type\u003c\/td\u003e\n\u003ctd\u003ePropane (LP)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eApplication\u003c\/td\u003e\n\u003ctd\u003eNew Construction, Existing Pool or Spa\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePool Type\u003c\/td\u003e\n\u003ctd\u003eIn Ground\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHeating Capacity\u003c\/td\u003e\n\u003ctd\u003e400,000 BTU\/hr\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eKilowatts\u003c\/td\u003e\n\u003ctd\u003e117 kW\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHeat Exchanger\u003c\/td\u003e\n\u003ctd\u003eStandard cupro nickel\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLow NOx\u003c\/td\u003e\n\u003ctd\u003eYes\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCooling Capability\u003c\/td\u003e\n\u003ctd\u003eNo\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLow Ambient Operation\u003c\/td\u003e\n\u003ctd\u003eYes\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMinimum Operating Temperature\u003c\/td\u003e\n\u003ctd\u003e40 degrees F\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eVoltage\u003c\/td\u003e\n\u003ctd\u003e120\/240V\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePhase\u003c\/td\u003e\n\u003ctd\u003eSingle\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFrequency\u003c\/td\u003e\n\u003ctd\u003e60 Hz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCircuit Amps\u003c\/td\u003e\n\u003ctd\u003e5.5\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaximum Breaker Size\u003c\/td\u003e\n\u003ctd\u003e15 Amps\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWater Flow Rate\u003c\/td\u003e\n\u003ctd\u003e30 to 125 GPM\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePlumbing Connections\u003c\/td\u003e\n\u003ctd\u003e2\" x 2-1\/2\" CPVC union\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRear Clearance\u003c\/td\u003e\n\u003ctd\u003e6\"\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSide Clearance\u003c\/td\u003e\n\u003ctd\u003e12\"\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Dimensions (H x W x L)\u003c\/td\u003e\n\u003ctd\u003e24\" x 34\" x 29.5\"\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Weight\u003c\/td\u003e\n\u003ctd\u003e195 lb\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eShipping Dimensions\u003c\/td\u003e\n\u003ctd\u003e30.6\" x 32.8\" x 39.6\"\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eShipping Weight\u003c\/td\u003e\n\u003ctd\u003e214 lb\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRefrigerant\u003c\/td\u003e\n\u003ctd\u003eNo\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eActive Defrost\u003c\/td\u003e\n\u003ctd\u003eNo\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBoost Mode\u003c\/td\u003e\n\u003ctd\u003eNo\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSilent Mode\u003c\/td\u003e\n\u003ctd\u003eNo\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eChannel\u003c\/td\u003e\n\u003ctd\u003eOpen Line\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eGTIN\u003c\/td\u003e\n\u003ctd\u003e610377387279\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003cdetails\u003e\n\u003csummary\u003eIs this unit propane or natural gas?\u003c\/summary\u003e\n\u003cp\u003ePropane.
