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.
