Simple Controls
• 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. Just set it, and forget it! Truly simple.

Wind Resistant
• Built-in Wind Resistant Design
The Raypak Millivolt has the best outdoor design in the market today. With over 50 years in designing and building gas heaters, Raypak has put all that experience into its newest design. No need for fans to combat drafting problems, the Raypak millivolt was designed for outdoor installations with its exclusive low profile design. It is so thoughtfully and carefully designed it actually protects itself from the things that tend to stifle ordinary pool and spa heaters: falling leaves, wind, airborne debris, rain, downdrafts, updrafts, sleet, snow, etc. In fact it is so efficiently designed it ensures uninterrupted heating performance regardless of all but the most extreme weather conditions. Built Raypak tough. Built to last.

 Cabinet

• Smart Design

One look will tell you that the Raypak Millivolt is different! The look is contemporary. The design is advanced. And inside and out it's engineered to last. The attractive forest green and charcoal gray panels complement the latest pool and spa equipment designs. Raypak's original "pagoda top" design will keep the heater operating even in extreme wind conditions and downdrafts. 

• Polytuff Powder Coating

The Raypak Millivolt has a polyester coated, non-corrosive cabinet that is more durable than solventborne and waterborne coated metal cabinets. Every piece of sheet metal that gets powder coated goes through a 7-stage wash system making certain the powder paint has a perfect bond. Underneath the tough and beautiful finish you will find galvanized metal that offers superior rust prevention and years of durable service.

Combustion Chamber
• Burner Tray
Every Raypak Millivolt burner tray is built to last. From the stainless steel burners to the aluminized metal used in the heat sensitive areas. In the event that anything should happen to your burners they can be quickly and easily serviced. One more reason why the Raypak Millivolt is made to take the work load year after year.

• Fire Tile

A ceramic fiber combustion box keeps your Raypak Millivolt running efficiently and keeps the outside jacket cool. By using this space-age material the heater won't retain residual heat after it is turned off, allowing it to be installed without the use of costly metal heat sinks.

Quality

• ISO 9001

Raypak is proud to be a ISO 9001 registered manufacturing plant. One more reason why Raypak is number one in the heater industry today. 

• End-of-Line Test

Every Raypak gas pool heater is plumbed and test fired before it is put in the carton. This ensures that your heater will fire right out of the box and continue to give you years of trouble-free operation. 

• Quality Checkpoints

The Raypak assembly process includes 6 final assembly quality checkpoints that help to ensure that each and every Raypak Millivolt is built correctly, and built to last. 

• CSA Certified

All of Raypaks products are CSA certified. The Raypak Millivolt is tested by CSA to the ANSI Z21.56 standard.
