Boiler scale occurs when hard water (water with higher levels of, among other things, calcium and magnesium) is heated and leaves deposits. The deposits are like a film and are unfortunately very poor at conducting heat, some say up to 37 times worse than steel. This means that the water heater needs more energy to heat the water, which in turn uses more electricity which causes the cost to increase for the household. If it gets really bad, the heating elements can also overheat, which in the worst case can damage or break it. If the boiler stone settles in the pipes, this will mean reduced flow and impair function.

Dissolve the scaleIt 

It is possible to dissolve scale with acid, for example vinegar. The problem is getting the acid down to the bottom and then getting out the solution and the dissolved deposit that looks like sand. To avoid the formation of scale, you can use an electric scale remover that creates an electric field, which means that the lime creates small crystals in the water and does not have the opportunity to form deposits.
