Laing ACT-303-BTRW AutoCirc Retro-Fit Circulator Pump

Laing ACT-303-BTRW AutoCirc Retro-Fit Circulator Pump

The Laing ACT-303-BTRW AutoCirc Retro-Fit Circulator Pump for Domestic Hot Water* is installed under the sink or faucet farthest from the water heater - where hot water usually takes the longest amount of time to arrive. A built-in temperature sensor automatically turns the Laing ACT-303-BTRW AutoCirc Retro-Fit Circulator Pump on when the water temperature in the hot water supply line cools down to 85° F. This cool water in the hot water supply line is then pumped into the cold water line and back into the water heater.

The Laing ACT-303-BTRW AutoCirc Retro-Fit Circulator Pump turns off automatically when the hot water supply line to the faucet reaches 95° F, ensuring the instant availability of shower warm water with maximum temperature hot water only seconds behind. When the pump is automatically turned off by the built-in thermostat, an auto closure device prevents hot or cold water from mixing in either supply line. Hot water will also be instantly available at all other faucets in the supply line between the water heater and the faucet where the AutoCirc pump is installed.

Note: At the sink under where the Laing ACT-303-BTRW AutoCirc Retro-Fit Circulator Pump is installed some "warmish" water will appear in the cold water line due to the transfer of water from the hot supply line to the cold supply line. This warmish water will, however dissipate in a very short time once the cold water faucet is opened.
