I had a new boiler and in-direct water heater put in. The water heater is a Pure-pro by amtrol and the boiler is a buderus. It was installed about 1yr 9m ago. After about a year we found if we took a shower for 30min, we'd lose hot water. So my hot water guy got amtrol to give a new tank under warranty. After switching it, we checked the coiled and he said it was spoiled. It was covered in some scaly build up after a year and a half. No one on my street has had this problem and they have had their tank for about 10yrs. The development is 10yrs old. Can this happen in such a short amount of time? What can I do?
thanks for any help
