AUTOCIRC

Instant HOT Water on Tap

Every tap in the house

Introducing Autocirc ® - The Autocirc ® pump will ensure that you no longer have to watch your water go down the drain while you are waiting for it to heat up. The water will be instantly hot and will cost the average home a mere 90c to run per month. Easy to install, Autocirc is the best solution for an existing home that would like to take advantage of having instant hot water on tap all the time.

TYPICAL INSTALL

Shown here is a typical installation of the Autocirc in the family home. The Autocirc is installed underneath the sink and requires only a single power point to operate. Installation is simple, just disconnect the pipes to the two taps, connect the pump and reconnect the pipes from the taps to the pump, set the timer and the jobs done.

The autocirc is not affected by the tempering valve, in fact when connected to a system using a tempering valve, it is even more economical. The Autocirc will pump through most non-return valves, however it cannot pump against a pressure gradient. If there is a pressure reducing valve immediately before your water heater, or between the cold water take-off and the water heater, this pressure reducing valve must be moved back to before the cold water take-off. Autocirc requires that both the hot and cold water pipes in the house be at the same pressure.

HOW IT WORKS

Autocirc senses the temperature in the hot water line, at the furthest extreme from your hot water heater. When the water temperature reaches a predetermined minimum it turns on and pumps water slowly from the hot water line back to the water heater, through the cold water line, and through a check valve, until the hot water again reaches the pump. At which time it switches off. It keeps doing this each time the water cools off during the time period you’ve set. The pump is only 33W, so it costs only 1 cent to run it for 8 hours (30% duty cycle). Far less than 1 light bulb and you have the pleasure of hot water when you turn on the tap.

MONEY SAVINGS

Not only are you saving water when using the Autocirc, you also reduce the running costs of your home. The graph on the left shows an example of a typical home and the amount of savings that can be achieved.

Having hot water on tap helps all around the house in many ways. The dishwasher will not need to heat the water. You can fill the jug with hot water and get a cup of coffee quicker and cheaper. This all saves you on your electricity bill by using your cheaper off peak electricity to heat water. On gas it’s even more economical.
