Smart Water

A small SmartWater® box can be installed by any plumber. Installation instructions are in the packaging and available here. The box is placed near the tap (hidden under the counter or in a vanity unit or cupboard) at the end of the hot water supply pipe. The hot water supply pipes are diverted through the box. When a person wants hot water they just press a button installed on the counter top – it shows blue whilst cold water sitting in the hot water pipe is drawn down. A valve in the box diverts the cold water to a tank that can be installed anywhere in the system. As soon as the hot water supply arrives the valve closes and the button turns red. The person then opens their hot tap and gets instant hot water. The hot water arrives just as quickly as it always did, but now no cold potable water is wasted.

If just one person uses a hot tap three times a day: they will save up to 20,500 litres of water per person per annum – 40.6% saving; They will save up to 585 kw of energy – 33.8% saving; and they will save up to 272 kg of CO2 – 34.08% saving.

Designed by plumbers, for plumbers. The University of Valencia has run tests and evaluated the benefits of this amazing device that can be installed by any qualified plumber. It works by saving and recycling on-site the cold water run-off that happens when someone opens a hot tap at a basin or shower, diverting it to a small expansion vessel. It stops all that beautiful, clean, potable water being sent down the sink and wasted and with a ROI of just two to three years, it makes financial sense too.
