Raypak Digital Control Swimming Pool Heaters

The Raypak Digital Heater replaced the Raypak RP2100 in 2004. All Raypak Digital heaters retrofit perfectly with the older model RP2100 heaters.

Total Control

The Raypak Digital swimming pool heater is equipped with a microprocessor-based control center. This control allows you to set your swimming pool or spa temperature precisely at your preferred setting just by pressing an up or down temperature control button. The digital display gives you a constant readout of your water temperature. Just set it and forget it! It is that easy!


Troubleshooting a Raypak Digital swimming pool 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 pool heater at all times. In the unlikely event that a problem develops, the digital display easily points out the problem and the probable cause. It’s like having a service technician built into every Raypak Digital swimming pool heater.


The Raypak Digital is compatible with most major brand swimming pool control and remote systems on the market today. Any two- or three-wire remote can connect to the Raypak Digital swimming pool heater and be integrated into the pool control system of your choice.

Wind Resistant

The Raypak Digital has the best outdoor design on the market today. Raypak has put its over 50 years of experience into the design of its latest swimming pool heater. No need for fans to combat drafting problems, the Raypak digital 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 swimming 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.

Heat Exchanger

Condensation-Free Operation

Both water temperature and flow rate inside the swimming pool heater are controlled to help eliminate condensation, sooting and scale buildup that can shorten the life of a pool heater. Raypak engineered the Unitherm Governor Specifically for pool heater applications, regulating low-temperature incoming water to help reduce condensation. Raypak has led the industry for over 30 years, setting the standard for condensation protection.

Rust-Free Waterways

The Raypak Digital Swimming Pool Heater, with polymer headers, is equipped with an integral copper finned-tube heat exchanger and stainless steel tube sheets. This unique construction guarantees rust-free operation, especially important when heating spas and smaller swimming pools. Even the smallest details such as the studs and nuts are made out of stainless steel. The Payoff? A swimming pool heater that will last year after year and can easily be serviced if the need should ever arise.


Stainless Steel Burners

Burner design is a critical component in any gas swimming pool 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.

Fan-Assisted Combustion

Not all swimming pool heaters are made the same. The Raypak design uses a fan to provide cool, controlled combustion air to the burners. Other brands use a fan to pull hot flue gases through the heater. The Raypak design allows the heater to outperform all others during cold starts and provide longer component life.

Pilot Ignition

Raypak Digital swimming pool 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 your swimming pool heater’s gas usage by not having a standard pilot. This is the most reliable and robust ignition system available, an industry-proven standard for over 20 years.
