If l install the system under my sink, will my shower have hot water too?
In most cases yes; by filling the main line with hot water, it will quickly deliver hot water to any fixture plumbed directly off of the main line.
Do l have to install the system at the furthest fixture from the water heater?
In most situations, it is best to install the D’MAND® Kontrol® System at the furthest point. By doing this, it will always fill the main line with hot water providing hot water to all fixtures plumbed off of the main line.
How much space will l lose under my sink? What are the dimensions?
20 cm long by 13.8 cm deep by 17.5 cm tall. In most cases, the D’MAND® Kontrol® System is installed behind the sink trap.
What if someone presses the button and hot water is already in the line?
The lockout feature will register that there is already hot water in the line and will prevent the D’MAND® Kontrol® System from activating.
How long does it take?
In most cases, hot water will arrive at least twice as quick. This can vary depending upon piping material, inside diameter, water pressure and the length of run from water heater to point of installation.
Where does the cold water go?
The cold or ambient temperature water standing in the hot water line is recirculated into the cold water side back to the water heater during the pumping process.
Can l install the system myself?
YES, but it is recommended to consult a Plumber if unsure.
Is a System needed for each fixture?
No. As long as all fixtures are plumed off the main line, one D’MANS® Kontrol® System will service your entire home.
How can l determine how my home is plumbed, or where my furthest fixture is in my home?
Turn hot water on at the furthest most perceived location and wait for water to arrive; then shut the water off. Now go back through your home towards the water heater testing other locations to see how long it takes to receive hot water. If you received hot water quicker than before, this is the benefit your will receive from the D’MAND® Kontrol® System. (This test must be performed when both the hot and cold water lines are at ambient temperatures).
Will it work with solar heating?
Yes, as long as there are no check valves restricting flow back to the water heater in the cold water line.
Will it work with water softeners?
Yes. When hot water is demanded, the cold water line will be purged out because we always mix hot with cold to reach a comfortable temperature.
What size system do l need?
a) Conventional Water Heaters (Gas or electric storage or Solar with Electric Boost) if you are waiting 2 minute or less for hot water at your furthest fixture, the S-71T is recommended but if the furthest distance is over 20 metres or over 2 minutes delivery time you will need to upgrade to the GS-03T -B3S model.
b) Instantaneous/Tankless Water Heaters or Solar with a Gas Instantaneous/Tankless Booster. You need the GS-03T-B3S model. The S-71T series is not recommended for Instantaneous/tankless or Solar with gas Boosted Instantaneous/tankless water heaters.
Can l turn my water heater to a lower setting?
Yes, but not below 60°C in accordance with the Australian Plumbing Code. By installing the D’MAND® Kontrol® System, the circulator delivers hot water to the fixtures very quickly without heat loss during travel time.
Can l install multiple buttons?
Yes. You may install as many D’MAND® Kontrol® System buttons into the low voltage wire as needed.
What are other ways to activate the D’MAND® Kontrol® System?
Activation buttons, remote transmitters, wired and wireless motion sensors are just a few options available to you. To receive more details contact, firstname.lastname@example.org.
Can l use remote and buttons at the same time?
What effect will the D’MAND® Kontrol® System have on city water flow?
None whatsoever. Outside city water pressure is unable to enter into a closed looped system unless fixture is opened.
Does the system heat water?
No. It is a pumping system the D’MAND® Kontrol® System works in conjunction with your current water heating system moving water quickly to the farthest fixture without the loss or waste of water as well as reducing energy losses.
Do l need an electric outlet installed for the system?
A standard 240V outlet is required to power the D’MAND ® Kontrol® System although it only draws 1 amp maximum for the larger GS-03T-B3S Model.
Does the system require special wiring?
No. The D’MAND® Kontrol® System operates off any standard 240V outlet. The S-70T/GS-03T-B3S System comes pre-wired for your convenience. Low voltage wiring may be required for additional push buttons or wired motion sensors.
How much will the system increase my electrical bill?
The cost to operate the D’MAND® Kontrol® System is around $2.00 a year.
How much pressure will be added to my water line?
There is no added pressure to your water lines. As hot water is being drawn to the furthest fixture, the cold water is returned to the water heater. There is a recalculating loop formed which creates no additional pressure.
Will it work on all water heating systems?
Yes. The D’MAND® Kontrol® System will work with oil, LPG/propane, solar, gas, electric and instantaneous/tankless mains pressure hot water systems.
How long or how much will it cost me to have a plumber install the system?
Most plumbers can install the D’MAND® Kontrol® System in around one and a half hours. The GS-03T-B3S may take slightly longer. If an electrical outlet is needed, this time must be included in your installation costs. The cost will vary on your plumber’s hourly rate.
Is major plumbing involved?
To install the D’MAND® Kontrol® System on a retrofit simply connect your hot and cold water supplies together at the furthest fixture underneath the sink using our custom “Universal Retro Fit Kit”. Or on a dedicated return line, simply remove the old pump and replace with your new D’MAND® Kontrol® unit.
Do l need to run a return line back to the water heater?
No. The D’MAND® Kontrol® System is designed to operate without additional plumbing. However, the D’MAND® Kontrol® System is adaptable to existing recirculation return line systems.
Should l put it on a timer?
No. the D’MAND® Kontrol® System allows hot water to arrive in seconds although several homes have used timers in cold weather climates to prevent pipes from freezing. Contact email@example.com for further information on this subject.
Do you have a plumber in my area you can recommend?
Experience has shown that in Australia most Plumbers are proficient enough to install the D’MAND® Kontrol® System, you should ask your local Plumber first. If problems exist please contact: firstname.lastname@example.org
How does this system save money?
By operating only on demand. The D’MAND® Kontrol® System allows you to reduce the water heater temperature setting as the D’MAND® reduces heat loss in the delivery of hot water to the fixtures Returning ambient temperature water back to the water heater and not allowing outside cold water to enter, prevents your water heater from cycling again.
How does the system save water?
By allowing hot water to arrive before turning on a tap, reducing cost of water and sewage. Average savings are 40 to 50 litres of water per day or around 15,000 + litres per year depending on size of family and/or family habits.
What effect will it have on my Rainwater Tank system?
It will reduce the amount of water pumped from the Tank and will also increase the life of the Tank pump.
How noisy is the system?
The System is extremely quiet.
How long can l expect the system to last?
Life expectancy is approximately fifteen (15) to (20) twenty years.
What is the warranty?
Five (5) year manufacturer’s warranty on pump and a one (1) year warranty on accessories.
If something happens after the warranty expires, are parts still available?
Yes. Contact your supplier at email@example.com
