The space saving Hatco C12 12 kW compact booster water heater has a 6 gallon capacity to provide plenty of hot final rinse water required to properly sanitize and flash-dry dishes and flatware. The Hatco C12 electric booster heater is factory pre-plumbed and pre-wired with a calibrated immersion thermostat and high-temperature limit switch. Fiberglass insulation minimizes heat loss, while the stainless steel front panel and powder coated body provide long-lasting durability. Swing-away front panels with low-water cut-off, control fuses, and transformer allow quick access to probes and elements for easier servicing. Water Quality Requirements: Incoming water exceeding 3.0 grains of hardness per gallon (GPG) must be treated and softened before being supplied to the booster heater. Water containing over 3.0 GPG will decrease the efficiency and reduce the operating life of the unit.
