One of my radiators started leaking yesterday evening. Looks like it's
around the thermostatic valve or the connection to the pipe below.
Probably something simple like a washer. We've got central heating
cover but the engineer may be a couple of days they say.
We had to bleed the radiator system last night to stop the leak, we
turned the main water supply off and bled the lowest radiator in the
house till it stopped.
We have an expansion tank in the loft (this is in addition to the cold
water tank that feeds the hot water cylinder). I believe the expansion
tank is used to refill the radiator system, is this correct? I've
identified a stop tap from the rising main into the loft - so this is
obviously the feed to the expansion tank, I've closed it.
So I presume it would now be safe to turn the water back on? Also
would it be safe to use the boiler for hot water (not heating
obviously). Or does it use the same circuit for hot water as for the
radiators, or does it depend on the type of system I have?
