The Raypak Raytherm is a gas-fired hydronic boiler with an efficiency of up to 84.0 AFUE. It uses a copper finned tube heat exchanger for greater heat transfer, and an electronic intermittent pilot ignition which improves efficiency by using fuel only when there is a call for heat. Stainless steel burners provide longer durability, and a built-in draft diverter helps increase the unit’s efficiency. Safety features include manual reset safety sensors which shut down the boiler if there is a flame roll-out or flue gas spillage and a fast response temperature sensor which shuts down the boiler if it overheats due to a low flow condition. All gas, plumbing, wiring and controls are located at the front of the Raytherm boiler for easy installation and serviceability.
