The Precision Boilers Model 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.
