A review of Raypak pool and spa heaters for residential applications, including popular and top-selling models, features to look for, and benefits they bring to homeowners. With the great selection of quality models that use gas, electricity, and heat pump technology, homeowners can easily find a water heater that will fit their needs.
The Raypak manufacturer offers heaters for both above-ground and in-ground pools, no matter the pool size, and with the variety of options and price range.
To choose the best water heater for your swimming pool, it is recommended to size the heater based on the total pool surface area. You can use different calculations with different pool shapes, as explained in the article about swimming pool heaters.
Raypak produces three main types of pool heaters for residential homes; gas-powered, electric type, and heat pumps.
Smaller devices, such as electric and some gas-type are designed for smaller pools and spas, while heat pumps and gas models with more power are meant for larger pools.
The pool heaters allow you to open a pool earlier and close it later, so you can enjoy it longer, even when the weather is cooler.
Selecting the correct pool heater type depends on the climate, weather, pool size, and user habits.
For example, you want a gas pool heater if you desire fast water heating, reliable temperature controls no matter the weather conditions, consistently high performance, and if planning to use it occasionally.
If you live in warmer areas and using the pool daily, get a heat pump as the most cost-effective solution. Heat pumps utilize the surrounding warmer air for heating and electrical heating elements if it is needed to increase the power.
Heat pumps are reliable and efficient while heating the water slower than the gas type.
Electric pool heaters are cheaper than the above two types, but they cost more to operate. They are recommended for smaller pools and spas.
There are three types of gas-powered pool heaters for home use:
Raypak gas pool heaters (available on amazon.com) for the above-ground pools are designed to use both natural gas and propane, offering two sizes; the 106A model, which is designed to provide the power of up to 105,000 BTU, and the 156A model with 156,000 BTU of power - both high efficient (82%) but not low NOx compliant.
The models use quality elements such as the ceramic fiber combustion box, stainless steel gas burner, and copper heat exchanger, allowing maximum heat transfer and corrosion-free operation for many years.
Model 106A is the smallest unit of all gas types, equipped with a simple control panel with the ON/OFF button and analog thermostat, allowing users to change the temperature easily.
Raypak 156A is more advanced, as it comes with the AFT digital control system so users can take advantage of the microprocessor-controlled thermostat, control buttons, digital display, optional remote control for temperature control, and self-diagnostics system for troubleshooting.
Both models are designed for outdoor installation using the atmospheric vent system, and due to its low-profile construction, the risk of wind affecting the gas-burning process is minimized.
They utilize the spark-to-pilot ignition system using the 120 VAC and 240 VAC, which activates only when there is demand, and a water bypass system to easily handle different water flows and control the condensation better.
Raypak Digital pool heaters come in several sizes: P-R206A, P-R266A, P-R336A, and P-R406A models, with the BTU input ranging from 199,500 to 399,000 BTU, when the heaters are equipped with the standard copper heat exchangers.
Users have an option to order models with stronger and durable cupro-nickel heat exchangers, which is more resistant to water chemistry, or ASME copper fin tube for commercial applications. The total BTU gas input is slightly different.
Raypak Digital heaters are also found with the low NOx gas emission: P-R207A, P-R267A, P-R337A, and P-R407A models, and the power of up to 399,000 BTU.
All the models are equipped with digital controls that feature the microprocessor-controlled thermostat and control buttons to adjust the temperature - accurately.
The onboard diagnostics system allows users to check the heater's status and get a notification when there is a problem. Users also have an option to check the flame strength and run time of the heater.
The heaters use two different ignition systems; digital electronic ignition, which requires 120 or 240VAC to generate the pilot on-demand, and millivolt design that does not require any external power as it uses the thermocouple and continuously burning pilot.
The gas burner is made of stainless steel and can self-adjust the flame for cleaner and efficient gas burning.
Raypak heat pumps can be purchased from one of the three groups:
The heat pumps from the Compact series are available as 2450, 3450, 4450 and are recommended to homeowners who live in warmer areas for daily pool heating, where the solar energy can be used as the primary source, or gas as a booster, automatically.
The most powerful model in this group is R4450ti, designed to provide up to 80,000 BTU power, but the most efficient of all Raypak heat pumps is the model R2450ti, which has a COP of 6.2.
Models are built strong so that they can resist harsh weather, corrosion, and damages from objects. Its sturdy cabinet, base, and scroll compressor can keep the sound level to its minimum without disturbing the surrounding.
Except for the long-lasting scroll compressor, which is more efficient than the piston-type found in cheaper versions, models also use the spiral titanium heat exchanger that can resist damaging pool chemistry that we use non-stop for cleaning the pool. The manufacturer provides a warranty of 10 years.
The heat pumps come with advanced electronics so you can easily set the temperature and forget about it, control with the optional remote, and use the diagnostics if something happens to the heater.
Raypak heat pumps from the Classic series, R5450, R6450, and R8450, are similar to the above models from the Compact series, while the R8450 models have an option to heat and cool, including the model R6450, which also has an option for the power defrost. By looking at the size and gas burner specs, you will see that models from the Compact series are bigger and more powerful - reaching high 140,000 BTU and COP of 6.0.
While the heat pumps from the Professional series are designed for commercial applications mostly, they can also be used in large homes with luxury pools, primarily due to the high BTU output of up to 170,000.
They are reliable and efficient, that contain professional-grade components such as stainless steel cabinets and titanium heat exchangers, including the microprocessor control, heat/cool, and defrost function. High-quality elements make them a favorite in areas with coastal weather conditions.
Raypak electric heaters come from the E3T Digital series and are designed for smaller pools and spas. They are small and lightweight, designed with quality components such as titanium heating elements and stainless steel cabinets to withstand extreme weather conditions and pool chemicals, and of course, last longer.
All these electric models include a digital control center where you can set and control the temperature (temperature knob), check the parameters on the large screen, so as the diagnostic code when the problem occurs.
The E3T heaters are available in four sizes ranging from 5.5 to 27 kW.
Most of the Raypak heat pumps come with the Copeland scroll compressor type, which is more reliable, durable, and has a reduced noise level than the piston type.
Look for the heat pump with the reversing valve as it allows not only heating but cooling too. Since icing up is the problem that occurs on the heat pump's condenser coils frequently, rapid defrost is something to consider.
Heat exchangers made of titanium and designed with spiral tubes make them last longer, corrode much less, resist damaging water chemicals and reduce deposit build-up.
Digital control and diagnostics systems allow users easier temperature control, better accuracy, simpler troubleshooting, and savings.
Buying a pool heater with a powder-coated or stainless steel cabinet ensures superior rust prevention and long life, even in harsh climates.
Environment-friendly design in gas pool heaters allows low NOx gas emission and reduced pollution.
Look for the pool heaters with either cupro-nickel or titanium heat exchangers and get one as it will provide years of reliable and well-performing operation.
Buying a pool heater is the long-term investment that will, with the pool, increase the value of your home and bring a lot of fun, joy, and comfort during hot days.
Raypak pool heaters are the perfect choice for homeowners who would like to extend the swimming season and enjoy pool parties not only in the summer but when most people are closing their pools. You will have your pool water ready, and at the temperature you set, no matter did you buy a gas type, electric, or heat pump. The right and accurate temperatures are easy to set, and if you want to have a heater with superior features, state-of-the-art design, and top performance, Raypak has it, and we have reviewed it.
Just look for the professional-grade components, energy-efficient features, high efficient and environment-friendly operation.
