Heating does not work in one room

To clarify - Intention was not to blame or accuse the vendor - Sorry if it sounded like that. But given that estate agent wouldn't let us check the heating / hot water arrangement made me slightly suspicious.

What on earth does it have to do with the estate agent? If you wanted to check the heating, you could have arranged that with the vendor. You weren't buying a house from an estate agent.

I did not attempt "bleeding" the radiator because I thought it needs to be done when the radiator is hot.

you think incorrectly. If the entire radiator is full of air it will be cold, if the inlet or outlet valve is turned off or stuck (for reasons unknown) it will be cold.

as a new homeowner perhaps add a basic DIY manual to your Christmas present list

This solved mine, my thermostatic radiator valve pin was stuck when I unscrewed it as per video:

When I got my place I was told the fridge(white goods) works. It doesn't. I'll just get a new one, got the house at a good price and its not worth the bother.

If your heating and hot water works I wouldn't worry about one radiator. If it were the whole heating system that would be a different matter.

Our 'fully working boiler' was condemned within a week of us moving in. Upsetting, but just one of those things.

However, on a more helpful note, try this first - even before bleeding the radiators.

Turn all the radiators off, except the cold one - make sure the valves are fully open on that one. Turn the heating on. There may be a simple air bubble that can be 'moved' this way.

I'm not sure of the exact terminology or science behind this, but within 5 minutes our - previously stone cold - radiator was toasty hot with no problems since.

It might be worth a shot?

Thermostatic radiator valves can get stuck - especially over the summer when they are not used for a long time. It's a common problem, which is often easy to fix in 5 mins.

Try googling 'stuck trv'.

Here's an example of what you'll find: https://www.youtube.com/watch?v=phFW-IIsH54

This was my first thought too, one of the radiators in our old house died about 5 years ago and this was the cause.

We actually had this sort of issue in our new build house and it was a combination of the thermostatic valve needing replacing and the rad was furthest away so low pressure. But just replacing the valve got it heating up again, just not very hot due to the pressure issue. Might not be too costly to fix

Don't wait for christmas. Get one now.

I got a RD DIY manual 40 years ago with my first flat and still use it (though in areas it's a bit dated!). Utube is pretty great for solving all sorts of things nowadays.

Take the head off the TRV and make sure the pin isn't stuck

And if this works, look at balancing the system. I bet the cold radiator is furthest from the boiler (in pipe run/resistance terms).


By closing down radiators to restrict flow on the ones nearest the boiler, you free up more capacity for the water to get to the further ones. Most plumbers only understand the basic concept of balancing but basically you want a 10-12C temperature drop across each radiator to allow maximum efficiency (and lower bills). Radiators that are close to the boiler but wound fully open tend to "hog" the water, returning it to the boiler at too high a temperature, not having dissipated the energy into your house instead and causing the boiler to cycle more frequently.

It is very time consuming (adjusting one radiator throws all the others out) which is why most plumbers don't bother, but the end result is worth it. I found my bills reduced and my house was warmer after carrying out balancing.
