RayPak Heaters

Raypak Heaters

Raypak has a few product lines of heaters. Raypak residential pool and spa gas heaters include above ground heater models; in-ground heater models from 200K to 400K BTU; and low NOX versions of the in-ground heatrs from 200K to 400K BTU.

Raypak also has a product line of residential pool and spa heat pumps with five models from 48K BTUs to 140K BTUs. The higher BTU heat pumps are available in a model with heating and cooling.

The Raypak Professional series heat pump pool heaters, from 140K BTUs to 170K BTUs, are designed specifically for commercial properties such as apartments, condos, hotels, motels, schools, parks, community and high-end private pools. It’s also appropriate in tough coastal weather conditions where salt air challenges durability.

Raypak also has a wide range of commercial gas pool heaters with BTUs up to 2,340,000 BTUs.

Rapak is a Rheem company and most HVAC companies know their way around the units and can get parts. You are not locked into installation and service through pool store channels. Raypak has a good warranty for heaters purchased separately and installed by a professional contractor, not necessary a pool company.

Low NOx Heater Model

Low NOx heaters normally have somewhat higher efficiencies and exhibit much lower NOx emissions.

They were developed to satisfy low NOx emissions requirements as first imposed by the South Coast Air Quality Management District in California. Your area might require a low NOx heater. You should consider a low NOx heater in any case.

Heater Hits Max Temperature before Actual Temperature

When automation is controlling the heater the automation temperature and the Raypak heater temperature can be different and the heater can hit its maximum temperature while the water is not yet to that temperature.

The default maximum temperature for the pool and spa can be raised.

See page 28 of the Raypak INSTALLATION AND OPERATION MANUAL

Spa Max Temp – Spa Setpoint Maximum Adjustment

Refer to step one on page 28 to access the program screen. Press the MODE button until SPA MAX TEMP appears on the digital display. Using the UP and DOWN buttons will change the Maximum Temperature Setting to your desired value. The control can be set for a maximum of 107°F (42°C).

Pool Max Temp – Pool Setpoint Maximum Adjustment

Refer to step one on page 28 to access into the program screen. Press the MODE button until POOL MAX TEMP appears on the digital display. Using the UP and DOWN buttons will change the Maximum Temperature Setting to your desired value. The control can be set for a maximum of 107°F (42°C).

Altitude Adjustments

Air is thinner and less dense as the altitude increases. A natural gas or propane heater needs an optimum mixture of air and gas. If the air/gas mixture is incorrect you will have an orange yellow flame instead of a good blue flame.

At higher latitudes the gas needs to be adjusted for the proper air/gas mixture.

• The Raypak Standard Digital is good to 2,000 feet.
• The Raypak Digital low NOx is good to 5,000 feet.

Atmospheric heaters: Rated inputs are suitable for up to 2,000 feet elevation. For elevations above 2000 feet, reduce gas input 4% for each 1,000 feet above sea level, as high elevation reduces combustion performance.

Lo NOx heaters: Rated inputs are suitable for up to 5,000 feet elevation. For elevations above 5000 feet, consult the factory.
