Recent research has been conducted over in the US into the difference in efficiency of hard and soft water and the subsequent impact on plumbing and heating systems.
The study has been conducted by the Water Quality Association, which recorded the drop in efficiency caused by hard water in both stored and tankless gas water heaters. The study found that for every 86ppm (parts per million) of hardness in the water (with 150ppm the common measure of hard water) there was a resultant drop in the efficiency of the systems of 4 per cent when using 190 litres a day.
So for those living in hard water areas the reduction in efficiency could amount to just under 10 per cent, whilst individuals in very hard water areas could experience a decrease in efficiency of 20 per cent. The research also found that hard water and subsequent build up of lime scale could damage water heaters, leading some to fail in less than two years.
This inefficiency increases energy bills, which many households are struggling to pay with the economy in such a sad state. There are however some excellent systems on the market that can protect your hot water systems from limescale and corrosion and increase the efficiency of the system along with its likely lifespan.
Most of these soft water systems use a patented zinc sacrificial anode system, which releases and combines zinc ions and calcium/magnesium ions together to from aragonite, which is a non-adhering lime. Once treated the water is perfectly drinkable and still contains the natural minerals that occur in water naturally.
