Universal H-Series Low NOx heater has an industry-leading thermal efficiency and complies with all current California air quality emission standards. The low NOx emission makes it a perfect choice for the environmentally concerned pool owner.

Its hydraulic performance also saves energy by reducing the circulation time of the pump and it can raise the temperature of an 800 gallon pool 30 degrees in less than an hour.

Other advances include stainless steel burners, corrosion-resistant heat exchangers and insulated Fire Tile combustion chambers. This traps the heat unlike other forms of insulation delivering the highest degree of performance from every BTU. Equipped with an LED control panel, it monitors heater performance for added convenience and maximum comfort with minimum effort. The ignition system delivers dependable lighting and reliable operations with just a touch of a button. The forced draft system constantly moves air through the combustion chamber to eliminate all outside weather variables affecting heating performance, such as wind conditions, eliminating the need to install a high-wind stack.
