Pool Heating

What good is a swimming pool if the water is just too cold?

Propane gas pool heaters

Swimming in a cold pool might be okay when you are 10 years old, but after making a large investment in your home’s pool and the very short swimming season we have here in the Northeast, many people want to get the best out of every day.


CES has been heating swimming pools of all sizes for decades with service backing every sale to make sure you get the most for your pool heater.


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 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 pool and spa heaters!

Raypak Pool and Spa Heaters

Raypak offers a complete line of gas heaters to fit almost every application. Inside and out, the Raypak Digital is the result of over 50 years experience in the design, engineering and manufacturing of all types of residential and commercial pool, and water heaters.

Technical Data

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.

Digital Controls Microprocessor Controlled Thermostat  The Raypak Digital 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 pool water temperature. Just set it, and forget it! Truly simple.

Self Diagnostic Troubleshooting a gas heater has never been easier. The Raypak Digital 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 The Raypak Digital is compatible with most major pool control and remote systems on the market today. Any two-wire or three-wire remote can connect to the Raypak Digital and be integrated into the pool control system of your choice.

Electronic Ignition Raypak Digital heaters come standard with intermittent spark ignition pilot safety controls. What this means is that the pilot only comes on when there is a call for heat. This is a more energy efficient way to control you heaters gas usage by not having a standing pilot. Raypak has been using the same reliable electronic pilot ignition design for over 20 years.

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.

Non-Corrosive Waterways Polymer Header The Raypak Millivolt incorporates the latest in header design technology. Raypak’s state-of-the-art engineering department utilized the latest in 3-D computer aided design to engineer the part for optimal performance. Polymer resin headers prevent rust stains from harming your pools surface giving you years of trouble-free swimming pleasure

All Copper Fin Tube Heat Exchanger  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 we use in our large gas commercial boilers.

Stainless Steel Tube Sheet  Stainless steel tube sheets are used on all Raypak Millivolt heaters that use the Polymer resin headers. This allows for a completely nonferrous waterway leaving your pool truly rust-free.

CPVC 2″ Water Connections Standard with every Raypak Millivolt is a set of 2″ slip fit CPVC water connections to make your installation secure and effortless.

Condensation Protection Standard on all Raypak Millivolt models is 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.

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.

Fuel Efficient   Efficient? You bet. Energy-smart Raypak heaters consistently achieve the highest efficiency ratings and the Raypak Millivolt is no exception. It exceeds all federal and state standards.

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.
