Radiators dont heat up very well

So as the radiators dont get hot it sounds like it definatly needs flushing or at worse new radiators

Thats not necessarily the case yet.

How warm is the house? I can't imagine needing the radiators hot at this time of year to be comfortable. Maybe the room thermostat has decided the room is warm enough and switched the radiators off. Also, if the house is nearly warm enough, it should only make the radiators warm, not hot.

Hi Yes i realise this and we dont have it on but would like to get it sorted in the warmer weather before the winter sets in and plumbers might charge more. When we want hot water for having a bath we switch the heating on just for the duration of the bath then its switched off again.

Hi thanks for getting back to me. Yes its a combi boiler. Its a 3 bed detatched house. The radiators dont have anything fancy on them like the ones you ve shown unfortunatly dont even have numbers on them. They are 30 years old apart from 3. There are 9 radiators altogether but the one in the kitchen is switched off.

Its not a small fluctuation in pressure it goes from normal to nothing but usually on the coldest day when we need the heating the most, dont know why.

Good morning: you have a two year WB Greenstar Junior combi and your system did not have TRVs installed when the appliance was installed or a functioning room thermostat...sounds as if the install was on the 'cheap' side i.e. lots of corners cut tbh.

Did you receive a Building Compliance certificate from CORGI and did the RGI complete the Benchmark Log? I suspect the CH system was not chemically flushed when the WB was installed:eek: You can look forward to further problems.

Call in a RGI, recommended to you by a source you trust, to investigate.

I agree with CH - you need to get someone in and have a proper look at this system for you as it sounds as though the install may have been bodged.

I suspect it wasn't flushed at all!

Thank you for all replies. Do any of you know approximatly how much it would cost for them to be chemically flushed before we go down the road of having new radiators.

Isn't a WB Greenstar covered by a 2 year warranty (as long as the 1st year annual service has been carried out by an WB approved RGI)? If so isn't it worth getting WB out on a warranty repair basis to establish if there is a fault on the boiler itself?
Assuming that the install was properly done and registered and that it's not yet gone out of warranty of course.

I'm fairly sure that the boiler won't provide hot water and heat the radiators at the same time. Have you tried the heating on its own?

Four of our radiators are from when our original system was put in in 1969 (Rayburn Rhapsody)

We now have a Combi (There were two boilers in between them) and never had a problem.
