Extend your swim season! Your pool and spa are a long-term investment and an added attraction that your guests enjoy. 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! The Raypak Millivolt pool and spa heaters will help you and your patrons get more enjoyment from your pool or spa.
Simple Controls - Mechanical Thermostat. Each 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!
Built-in Wind Resistant Design. The best outdoor design in the market today! No need for fans to combat drafting problems, the Raypak Millivolt was designed for outdoor installations with its exclusive low profile design. It actually protects itself from the things that tend to stifle ordinary pool and spa heaters: falling leaves, wind, airborne debris, rain, snow, etc. It ensures uninterrupted heating performance regardless of all but the most extreme weather conditions.
Cabinet Smart Design and Polytuff Powder Coating. The look and design is contemporary and advanced. Raypak's original pagoda top design will keep the heater operating. It has a polyester coated, non-corrosive cabinet that is more durable than solventborne and waterborne coated metal cabinets. Underneath the tough finish, you will find galvanized metal that offers superior rust prevention and years of durable service.
Non-Corrosive Waterways and All Copper Fin Tube Heat Exchanger. Polymer resin headers prevent rust stains from harming your pools surface giving you years of trouble-free swimming pleasure. Raypak's state-of-the-art engineering department utilized the latest in 3-D computer aided design to engineer the part for optimal performance. All Raypak Millivolt gas heaters come standard with integral copper finned tube. This means that the fin tubing is made from one piece of extruded copper tube. Since the fins are integral to the tube, maximum heat transfer is attained.
Every Raypak Millivolt has the same robust design tube bundle that they use in the large gas commercial boilers. Standard with every Millivolt is a set of 2 inch slip fit CPVC water connections to make your installation secure and effortless. The Millivolt models also include Raypak's Unitherm Governor which helps reduce condensation from low inlet water temperatures. The Unitherm Governor automatically regulates the water flow to help keep the water temperature in the heat exchanger above 105°. Both water temperature and water flow rate are controlled to eliminate condensation, sooting, and scale buildup that can shorten heater life. 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 inch plumbing systems. More hot water moves through faster and more efficiently.
Energy-smart Raypak heaters consistently achieve the highest efficiency ratings and the Raypak Millivolt is no exception. It exceeds all federal and state standards. And 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. All Raypak products are CSA certified. The Raypak Millivolt is tested by CSA to the ANSI Z21.56 standard.
