All Indirect water heaters have a problem accurately controlling the output water temperature. The location of the sensor, the rate at which the tank heats, and the overall accuracy of the thermostat, all contribute to outlet water temperatures 20 degrees or MORE above the setting on the thermostat. This can lead to unsafe installations or require expensive mixing valves.

TPI eliminates this danger and cost by using microprocessor intelligence to safely control the outlet water temperature to within 2 degrees of the set point.

The temperature at which you set the thermostat is the temperature of the water coming out of the tank. No other thermostat can make that claim.

Mounts directly to any tank for lower profile, more secure installation.

Fits any standard immersion well...no special adapter required.

Green Indicator light blinks when thermostat is calling, solid when satisfied.

Red Indicator light indicates a fault.
