Hi.
We have a conventional boiler - boiler, hot water cylinder, cold water tank and expansion /header tank (both in loft). The boiler has one motorised valve. I need to replace a leaking valve on a towel radiator - which only comes on when the hot water is switched on. I assume this is on the pipe run between the motorised valve and hot water cylinder. I don't know if the return from the tail goes back onto this pipe, or back into the radiator return loop, if that's makes sense.
I've drained down the radiators before without issue (drain point on radiator, stop valve on loft tank to stop the rads from re-filling), but what do I need to do to drain water from the hot water loop/stop the flow?
Boiler photo - hot water goes right of motorised valve.
Tank - left pipes don't have any stop valves. Right pipes at top (hot - hot tap water right?) don't really have any valves either.
Is it done in the same way as the central heating?
Thanks
