Instantaneous Steam-to-Hot Water Heater

The EnviroSep Model IWH, Instantaneous Steam-To-Water Heater is a simple and accurate manufactured, ready-to-install system designed to address the requirements of commercial potable water heating systems. Designed to utilize steam as the heat source, the steam is supplied to the heater at a predetermined 2 to 60 psig (depending on required output). Blended Cold Water and Hot Water (Loop) Return is supplied to the heater and the Hot Water Supply is set through a manual Temperature Control Valve. The Model IWH is constructed of Stainless Steel, Copper, and Bronze components suitable for domestic water use. Capable of handling a wide range of water flowrates and temperatures, while being Custom-tailored to your specific site needs, makes this system an ideal choice for either new or retrofit installations.
