Water Softener Efficiency and Part G Building Regulations

Water softeners have proven benefits on the environment especially regarding  saving energy. – Studies have shown that 0.8mm of limescale increases fuel costs by 10%.  Soft water means a reduction in use of detergents and soaps which contain chemicals that pose a threat to the environment.

A water softener produces a carbon benefit as they actually reduce carbon emissions.

Water conservation is a growing environmental concern.  The Part G Building Regulations cover water efficiency and the requirement to use appliances that use water efficiently.

The good practice guidance for a water softener is it should not use more than 4% of its capacity for regeneration.

The calculations below show Tapworks water softeners are well within the guideline.

The figures below are based on a UK average water hardness of 300ppm

Ultra 9 water softener will use a maximum  of 45 litres of water to regenerate after creating 1690 litres of softened water.

= 2.66% of its capacity

AD11 water softener will use a maximum of 49 litres of water to regenerate after creating 2266 litres of softened water.

= 2.16% of its capacity

Infinity water softener will use a maximum of 52 litres of water to regenerate after creating 2648 litres of softened water.

= 1.96% of its capacity

The good news is that because of the Tapworks Genius Chip and our proportional regeneration – our water softeners work in a way that makes them even more efficiently that the statistics show.
