Our Indirect Water Heaters are the most user friendly units in the industry. All pipe connections are located on the top for clean, easy installation and maintenance. Tanks are shipped with drain valve, T&P relief valve, and a welded stainless steel cold water dip tube factory installed and pressure tested. A Honeywell temperature control is offered as standard equipment with all single coil Indirect Water Heaters and Hot Water Storage Tanks.

Hot Water Heating System Storage Tanks are designed with dedicated heat source supply/return dip tubes located to result in precise temperature control. The supply and return from the heat source is hydraulically decoupled from cold and hot connections and flow variations.
