| New hot water circulation pumps from Laing Thermotech  Laing Thermotech offers an innovative line of hot water circulation pumps that give consumers the convenience of instantly having hot water at every faucet in their home. With these hot water delivery products, homeowners no longer have to wait for water to heat up at their shower or faucet. The Autocirc is geared for retrofit applications, while the UltraCirc is designed for new construction. Both systems integrate easily with the existing hot water supply line. The Autocirc1 pump installs under the sink or faucet farthest from the water heater-where hot water has to travel for the longest time.A built-in temperature sensor automatically turns the pump on when the water temperature in the hot water supply line cools down to 85ºF. The cool water in the hot water supply line is then pumped back into the cold water line and back into the water heater. 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. The Autocirc2 works in a similar fashion to the Autocirc1, except it has two components: a pump and valve. The Autocirc2 pump is installed at the water heater and controlled by a timer, while the valve is mounted under the sink farthest from the water heater. When the hot water supply line becomes cool, the adjustable thermostatic valve allows the cool water in the hot water supply line to flow into the cold water supply line, replacing it with hot water. The UltraCirc is a compact recirculation system that includes a timer-controlled pump and several valves. A return line is run from the last tap on the hot water supply line back to the water heater. Hot water is circulated in the supply line and immediately becomes available whenever someone turns on the faucet. write your comments about the article :: © 2006 Construction News :: home page |
