Radiators hot even though the central heating isn't on - any idea why?

[Loueytb3]

The past couple of days I've noticed that our radiators have been hot even though the heating has been off for a while. It seems to be while the hot water is on as they go cool after the hot water goes off. Anyone have any idea why and do we need to get a plumber out?

What is off?

Show us pics of your boiler, pipes around the cylinder, timer/programmer and wall thermostat, and of the control knobs on your radiator valves.

Do you have your own gas meter? It is very curious to hear that your neighbour controls your heating.

my radiator has a turn switch which I need to turn on for heat, this is off, I live in a complex of maisonettes, two together, one has control of the central heating so if my neighbour switches it off, I cannot get heat. I have complained about the heat to the Landlord, and he replied that the neighbour would have to stand on a chair to change the settings, one does not need to be Sherlock Holmes to find someone else to stand on a chair and change settings.

No pics?

You are saying that your radiator is hot even though you have turned the knob to off? In the absence of photos I would guess that the radiator valve is faulty, though some can be set with max/min limit stops.

I tried to download a picture, but it won't go through, the switch was working when I first moved into the flat, when my neighbour re gassed her heating is when the problem first occurred, their is a heavy smell, and the heat hits you when you enter the maisonette, even though the bedroom is above the lounge.

Hi, I have just posed this problem to the University of Kwa Zulu Natal, as I know someone who may be able to assist me there, however, I would think that not having control of gas central heating would not pass the building or health and safety inspector in Natal, and of course, one does not need central heating there.

My heating is off but radiators are hot, we are waiting for this to be fixed. In the meantime, is it costing us.
Thanks
