Radiators not hot!

Hi All,

Firstly, I'm a bit of a dunce when it comes to plumbing so go easy on me.

I have just tested my heating & noticed a few of my radiators are not working great. I live in a townhouse & the radiators on the bottom floor are fines, one on the middle floor is cold at the top & two on the top floor are the same. A third radiator on the top floor is completely cold. I have tried bleeding but although air comes out no water does, which suggests the pressure isn't high enough. Any ideas?

One thing I have noticed is that is that there is what appears to be a grey plastic cistern on top of the boiler but seperate from it. This is completely empty. Should it have water in it?

Thanks for any help,

Gareth

Yes it needs water.
Read the manual.
Or down load one from the link posted on here.

Hi
to start, you have to find the filling loom ( prob. close to your Gars Boiler in the kitchen?) the pressure should be at least 1 bar maximum 1.5. ( after bleeding the radiators, water comes out of the bleeding point! do the top floor radiators firs)
And yes your Gray top tank should have water in it, the level should be maximum to the middle rim of this gray tank.
