Description for Lochinvar SIT030

**NOTE: Compatible Honeywell L4006A1967 Aquastat Controller available

The Squire uses the power and efficiency of the boiler that heats the home to generate domestic hot water for showers, dish washing, clothes washing - any hot water demand required. The efficiency of the boiler used to heat the home can be as much as 20% higher than a direct-fired tank-type water heater. So why not use that efficiency to "indirectly" provide hot water for all domestic applications?

The Squire passes the boiler water used to heat the home through a uniquely designed internal helical coil that is immersed in the water heater tank. The super heated coil then passes its energy directly to the potable water. The end result is hot water for domestic use from boiler water already being used to heat the home. By using the Squire, to indirectly heat the domestic water, you eliminate the additional gas line, electrical connections and vent ducts needed with direct-fired tank-type water heaters.

Comments about 27 Gallon, Squire SIT030 Indirect Water Heater:

Well insulated and nice build quality. When full of 140 degree water the outside isn't even slightly warm to the touch.

    Is the energy factor greater than .61?

      Indirect water heaters do not have Energy Factor ratings. They are only as efficient as the boilers used to operate them.
