Instant hot water - prevent water waste with quick and piping hot water.

Instant Hot water? A hot water recirculation system circulates the hot water in your home so that when you open a fixture the water is warm immediately. There is no need to run water down the drain waiting for hot water to arrive.

Hot water recirculation systems save water, energy and money; the average family of four wastes up to 17,000 gallons of water per year just waiting for hot water to arrive. A hot water recirculation system eliminates this waste, and provides the luxury and convenience of instant hot water. A hot water recirculation system pays for itself through reduced water and sewer charges and reduced water heating costs. As a general rule of thumb a hot water recirculation system will pay for itself if you have to wait 30 seconds or more for hot water to arrive at the fixture.

There are two ways to incorporate a hot water recirculation system into you home, a conventional system with a dedicated return line or an under the sink retrofit system which uses your existing plumbing and no return line is required.

A conventional system is typically a new construction item installed when you are building a home.

The under the sink retrofit systems were designed for existing home applications; since they can easily adapt to your existing plumbing without the need to install a dedicated return line, however these systems can also be used in new construction applications.

It is generally recommended that if you have the ability to install a conventional system with a dedicated return line that this is the best way to go. If you cannot or choose not to install a return line, under the sink units are a viable alternative.

Now you can have hot water in 25-45 seconds (depending on the size of the home and water system) without wasting a single drop and by using only a fraction of a cent's worth of electricity.

Using the existing hot and cold water lines, the Dux readyhot system rapidly displaces the ambient temperature water in the hot water line with hot water coming from the water heater.

It returns this ambient temperature water through the cold water line to the water heater without letting any water run down the drain or bringing new, colder water into the house.

Once hot water has reached the fixture, the sensor closes the valve and turns off the pump not allowing hot water to enter the cold water line. The system is operated on demand, generally running for less than a minute each time it is activated. Because the lines do not have the flow restrictions of the fixtures, less water is drawn from the water heater and it arrives at a hotter temperature more quickly.

How it works:

The Hot Water D'MAND System can be easily retrofitted or installed new on any home (including manufactured homes and large pleasure craft) or business, regardless of how the building is plumbed for hot water. However, in new construction, Structured Plumbing™ should be incorporated into the design, so that the entire hot water distribution system is more effective.

Features:

The Metlund Hot Water D'MAND System consists of a high performance circulating pump, electronic zone valve, electronic control circuit board and various activating controls. It can be installed with any water heating system: gas, electric, propane, tank, solar or tank-less heaters. In most retrofit applications, the Hot Water D'MAND System is installed at the fixture furthest from the water heater.
Its features include:

* Automatic "fail-safe"
* 3-year (S-51, S-71T and S-03) warranty
* Life expectancy 15 to 20 years
* Less than $2.00 a year to operate
* Delivers hot water within seconds to more than one fixture
* Delivers hot water without wasting cold water down the drain
* System only operates when there is a demand for hot water
* Simple installation for new and existing homes
* Works with all standard water heaters (gas, electric, instantaneous, propane and solar hot water)
* "No Sweat" easy installation package available with optional remote control button
* Australian Standards ATS 5200.464-2004
* UL Listed and IAPMO Approved

Savings of energy and water, plus extending the life of water heaters, has a significant return on investment. Building regulations require the use of low flow fixtures (9 litre 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.
