The resistance heating
element on our Quick B3 40 liter hot water
boiler got all calcified and scaly last year, leading the water
to have a sickly sweet / sour smell. I replace the element and after only one year, the same problem reoccurred. I suppose we have hard water, but I would have hoped for more than a year. Any ideas as to why the problem recurs so frequently and what, if anything, can be done about it? Thanks.
