Quietside DPW Dual Purpose Gas Fired Heaters

Posted at 9:28 PM


The Quietside DPW-099A, DPW-120A and DPW-199A Dual Purpose Water Heaters provide both closed loop heating water, for radiant fan coil, and other hydronic application plus with the convenience and efficiency of on-demand domestic hot water. Three capacities-99,000 ,120,000 and 199,000Btu/h available. These Units have efficiency levels of 90% AFUE on the heating operation and an energy factor of up to 0.85 for DHW production. These outstanding efficiency levels are achieved by utilizing 2 heating exchangers, including a wet recuperative heat exchanger. This heat exchanger condenses extra energy from the hot flue gas to provide additional performance and energy. These units are capable of being vented in schedule 40 PVC.
