Metlund® Hot Water D'MAND® Systems


Do you have to run your water a long time to get hot water? I did and it concerned me that I was not only wasting a lot of water that my well pump had pumped 600 feet to the surface, but I was using a lot of energy and over-taxing my septic system as well.

Now you can have hot water in 15-30 seconds (depending on the size of the home and water system) without wasting a single drop and by using only a fraction of electricity.

The Metlund® Hot Water D'MAND® System (a high performance pump, integrated controller and electronic zone valve), requires no special plumbing. It is designed for use with any hot water heating system to provide energy and water savings. It's easy to install in new or existing homes or businesses.

Savings of energy and water, plus extending the life of water heaters, has a significant return on investment. Federal regulations require the use of low flow fixtures (1˝ gallon restrictors on fixtures and 2˝ gallon restrictors on showers). Since eight out of ten homes have long waits for hot water at one or more fixtures, it is easy to see the added convenience and cost savings of instant hot water delivery.

Metlund Systems are approved and/or certified by The Department of Energy, Underwriters Laboratories, The HandyMan Club of America, BCHydro PowerSmart and the Uniform Plumbing Code.

The Hot Water Demand system (HWDS) is an electric water pumping system that quickly (typically within 30 seconds) brings hot water to the fixture by drawing water from the hot water tank and returning ambient house temperature water back to the hot water tank where it is heated. The HWDS is usually installed under the sink farthest from the water heater. At the push of a button, it circulates the ambient house temperature water normally discarded down the drain, back to the water heater through the cold water line. At the same time, the HWDS pumps hot water rapidly from the hot water heater to the fixture. When a predetermined set point temperature (usually 5°F above room temperature) in the line near the fixture is reached the pump stops automatically and hot water is subsequently available at the faucet. The pump may be operated by a switch placed next to the fixture or by a remote control
