Millivolt Models

• Mechanical Thermostat - The Raypak Millivolt gas heater comes with one mechanical thermostat. This control allows you to set your pool or spa temperature precisely at your favorite setting.
• Millivolt Controls - No power source is required for the Raypak Millivolt heater. All operating electricity is supplied by the pilot thermocouple.

Stainless Steel Burners
Burner design is a critical component in any gas heater. The stainless steel burner system used in the Raypak Digital is inherently forgiving and extremely robust. The burner is self-adjusting to compensate for gas pressure fluctuations, allowing the heater to always burn clean and safe.

Smooth Light Off
 The soft-opening gas valve ensures smooth turn-on; no “Hard Light” to worry about. The easily removable burner tray and pilot assembly make service and maintenance a simple task.

Pilot Ignition
The Raypak Digital uses a spark-to-pilot ignition system. This is the most reliable and robust ignition system available–an industry proven standard for over 30 years.

Condensation-Free Operation
Both water temperature and flow rate inside the heater are controlled to help eliminate condensation, sooting and scale buildup that can shorten the life of a heater. Raypak engineered the Unitherm Governor specifically for pool heater applications, regulating low-temperature incoming water to help reduce condensation. The built-in automatic bypass helps prevent scaling and erosion by balancing the flow going into the heat exchanger.

Rust-Free Waterways
The Raypak Digital, with polymer headers, is equipped with an integral copper finned-tube heat exchanger and stainless steel tube sheets. Even the smallest details such as the studs and nuts are made out of stainless steel.  A heater that will last year after year and can easily be serviced if the need should ever arise.
