GOULDS WATER TECHNOLOGY Laing Thermotech Autocirc E1 E1-BCANCT1W-06 Series Undersink Instant Hot Water Circulating System with Plug

The autocirc is the most efficient system, turning on only when the system needs to be replenished with hot water. The pump is installed under the sink farthest from the water heater where hot water takes the longest to arrive. No recirculation line is required. Hot water will also be instantly available at all other faucets located on the hot water supply line between the water heater and the faucet where the autocirc is installed.
