Raypak pool heaters are produced by Raypak inc. a California based company specializing in water heating systems including commercial boilers, water heaters and control systems, pool and spa heaters, and residential boilers. Founded in 1947 the company has grown rapidly and now supplies its products worldwide. Its goals have always been to achieve high quality, reliability and energy efficiency. The company was pleased to become the first boiler manufacturer to achieve ISO 9001 registration in 1996.
The current range includes:
- Raypak Digital Heater – This is often referred to as the RP2100 although that is actually an older model. With models ranging from 200 to 399 BTU/hr, the Raypak digital heater is designed to minimize condensation and provide rust free waterways. It will provide years of trouble free use and be unaffected by all except the most extreme weather conditions. It is microprocessor controlled with electronic ignition and on-board diagnostic controls. Basically you just have to set the required temperature and the heater does the rest. There is also a low NOx version of this heater which exceeds all NOx emission requirements.
- Raypak Millivolt Heater – This is very similar to the Digital heater except that it has a standing pilot light to provide ignition, uses a mechanical thermostat and has no diagnostics.
- Raypak Heat Pumps – For 2019 Raypak have revised their lineup of heat pumps (details on the Raypak Heat Pump page) but most of those on sale are still the 2018 models – the Compact Series, the Classic Series, the Specialty Series and the Quiet Series. All feature a titanium heat exchanger to withstand corrosion. There is a choice of analog or digital controls but in both cases you can control pool and spa temperature separately. Some of the Specialty models can be switched into reverse to provide pool cooling in summer and also feature a defrost mode to prevent ice forming on the condenser.
Of these Raypak pool heaters which is best for you? Well the first thing to decide is whether you want a gas heater or a heat pump. Assuming that getting electricity to the pool location is not a problem, a heat pump will be best if you keep your pool heated most of the season. Although the purchase price is higher than a gas heater, a heat pump has much lower running costs. You might prefer a gas heater if you only heat your pool occasionally because gas heaters are more powerful and can get a pool up to the required temperature more quickly. They are also cheaper to buy and if they are not used a great deal then this advantage will not be wiped out by the higher running costs.
Assuming you are looking at a gas heater then you would go for the digital heater (or the low NOx version) if you can provide an electricity supply to the heater. If not you will have to go for the Millivolt heater.
Either way you will find that one of the Raypak pool heaters meets your needs.
