Enjoy your pool......Extend your swim season
Your pool and spa is a long-term investment that you, your family and friends will enjoy year after year. Now, there’s an easier way to enjoy that investment more often, more reliably and more efficiently throughout the year...the Raypak Millivolt pool and spa heater.

Think about being able to use your pool or spa at the perfect comfort level even when Fall arrives...or when the first chill of Winter is felt in the wind...or in the Spring or Summer when evenings can turn chilly in a minute! Helping you get more enjoyment from your pool or spa is the smart idea behind the Raypak Millivolt.  

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.

• High Flow Rates
No need to worry about large pumps or high flow systems. The Raypak Millivolt comes with an automatic bypass built into the header. You'll find that the Raypak Millivolt delivers the industry's lowest pressure drop and highest water flow rate - up to 125 gallons per minute - exceeding the maximum recommended for 2" plumbing systems. More hot water moves through faster and more efficiently.
