When after filling the hydronic heating system do you need to have the city supply turned on into the system?
Does the system use water and need refilling?
If you have a leak wouldn't it be better to let the system run down and shut down the system?
there a 2 schools of thought on this:
if you automatically refill your system, the homeowner may have a leak and it could remain undetected, with replacement water( with its own oxygen supply,which is bad) taking care of keeping sysyem filled.
if no auto refill,then a leak means your system pressure drops, and eventually the homeowner is aware there is a defect
