OK here's a question probably for the more mature central heating expert.
I live in a block of flats from the mid 1970s which had communal heating installed at the outset - obviously the boilers have been changed but the pipework, radiators and controls in the flats are basically original. My flat happens to be above the boiler room so is generally pretty warm - never dropping below about 21-22C, so I've always had the heating turned off using the master heating stop valve. As I have some Australians visiting over the winter, and in case it turns very cold, I thought perhaps I should check if the heating works. It doesn't.
The problem looks as if it is with the 'regulator' (no idea if that's the right word) - which is connected to a Danfoss control knob in the hall marked 1 to 5 via long length of unsheathed flexible metal wire - which doesn't look as if carries a current. The hot water is reaching the 'regulator' (ie pipework is very hot up to it) but not going beyond - whichever way the control knob points. Basically I'd like to figure out if there's a way of opening this device all the time so that hot water will flow around the system whenever the stop valve is open.
First pic shows the 'regulator' in situ, the second removed from the device, the third the control knob.
Thanks guys and gals.
