: Raypack has been known to heat domestic water with the heating system; but I have some doubts that has been applied to a slab system. you can answer which is fact.
: If you use a boiler for domestic water, then scale is a usual result of having the calcium and magnesium in water harden on the inside of tubing, blocking passage.
: As boilers are more often used in SEALED systems at 15 to 20 psig pressures, no scale enters to do that unless there is a serious leak being made up all the time. Thus scaling doesn't happen in 'normal' slab heat systems.
: So there is some confusion here from inadequate information as to the cause of the problem.
: It is possible the gas regulator has lost some pressure, derating the boiler as a cause and a proper service would restore it. IOW, buying the premise before knowing what is the cause is just guessing in the wind. Replacing a boiler because it needs descaling so the new boiler can scale up again from improper care is a waste of money.
