Short Description

Pool Heater Features:

  • Digital LCD for temperature control and heater settings
  • 2" glass-lined Cast Iron headers

  • ANSI Z21.56 design certified
  • Altitudes from Sea Level to 9,000 ft.


ASME rated heaters are intended for use when local codes mandate the use of ASME-certified equipment in commercial installations, such as apartment, condominium and public pools and spas. NOx jointly refers to nitric oxide (NO) and nitrogen dioxide (NO2), two oxides of nitrogen that most affect pollution. Low NOx heaters produce less harmful emissions than regular heaters and are ideal for any eco-friendly application. The Raypak commercial digital heater is factory equipped with ASME waterways for commercial use and comes with a microprocessor based thermostat control. This allows the user to set the pool or spa temperature at a precise temperature using the up or down button. The digital display provides a constant reading of the pool's water temperature.

Pool Heater Highlights:

Cast Iron Glass-lined Header

Controlled Thermostat

The Raypak Digital Low NOx gas heater comes with a microprocessor based thermostat control. This control allows you to set your pool or spa temperature precisely at your favorite setting just by pressing an up or down temperature control button. The digital display gives you a constant read out of your swimming pool water temperature.
Self Diagnostic

Self Diagnostic

Troubleshooting a gas heater has never been easier. The Raypak Digital Low NOx has on-board diagnostic controls that let the user and the service professional know what is going on with the heater at all times. In the event that you would ever have a problem with the heater, the digital display will show where the problem is in the control circuit. It's like having a service technician built into every heater.
Remote Compatible

Remote Compatible

The Raypak Digital Low NOx is compatible with most major swimming pool control and remote systems on the market today. Any two-wire or three-wire remote can connect to the heater and be integrated into the swimming pool control system of your choice.
Copper Fin Tube Heat Exchanger

Copper Heat Exchanger

All Raypak ASME gas heaters come standard with .065" wall integral copper finned tubes. This tubing is over 50% thicker in wall thickness than standard tubing. Since the fins are integral to the tube, maximum heat transfer is attained. The fin tubing is made from one piece of extruded copper tube, not from separate fins attached to the copper tubes. Every Raypak ASME has the same robust design tube bundle that is used in Raypak's large gas commercial boilers.
