The PHWS indirect fired water heater uses existing thermal energy sources to heat domestic hot water. The vessel is fitted with a shell-and-tube heat exchanger that accepts either process steam or high temperature hot water to heat the potable water stored inside the NSF-61 compliant vessel. For ease of installation, the water heater is shipped fully assembled and ready to use with all the accessories factory-sized, pre-piped and pre-wired. The PHWS saves time, money and manpower that would otherwise be used to install a separate fuel-burning device inside the facility.
Features & Benefits
Storage capacities range from 125 gallons to 4,000 gallons of actual capacity.
Precision Seal, our two-part epoxy alternative to glass lining, is suitable for storing water up to 180°F; unlike glass, it can be repaired in the field.
PS-lined vessels include a five-year warranty; the last two years are pro-rated.
Cement-lined vessels are suitable for tanks larger than 36 inches in diameter and for higher temperature service, up to 250°F.
Cement-lined vessels include a ten-year warranty; the last five years are prorated.
Potable water is heated by a single-wall or double-wall shell-&-tube heat exchanger(s) equipped with either copper or copper-nickel tubes and selected to fit the unique recovery requirements of each application.
