Laundry operations require substantial quantities of hot water on very short notice. The water is supplied to an open loop directly from municipal sources which are typically at a temperature of about 50F. Unlike many other boiler brands, Gasmaster Industries boilers require no tempering of the water before it enters the heat exchanger.

The stainless steel heat exchanger will never add any impurities to the water being heated. The high efficiencies mean that the operator maximizes its income by minimizing operating costs and the instantaneous supply of hot water leads to other savings, such as tanks etc., in the mechanical design of the plant.
