NOTE
In certain areas, water supplies may have a high mineral content. This will lead to lime build-up
in the coil and blockage depending on the mineral content, boiler temperature, and the amount
of water passing through the coil. Coils should be cleaned or replaced as soon as there is any in-
dication that the hot water supply is being restricted. Coils can be cleaned with hydrochloric
acid, but is very dangerous and should be attempted only by qualified and experienced person.
