Radiators not heating up

[terryplumb]

It goes to 400 ,but the way it works is... Engineer arrives ,diagnoses and advises you of time it will take / and the price bracket .At which point you can say go ahead or no thanks.However ,you must pay the half hour charge come what may . which is fair enough.

oddly it has come on now... but only lukewarm and very slowly heating up

 

[cbrand]

in over 20 mins only the radiator is in the hallway has become lukewarm. But the hot water from hot is very very hot

 

[terryplumb]

Yes ,its obviously restricted. Probably a bit of cruds got in there from draining down maybe ,just unlucky !!
Ps a mate of mine just had BG out ,fitted new diverter service kit ,twenty mins and , 90 quid. On their one off boiler repair. Not same boiler as yours ,cant remember what his is ,think its a biasi. Anyway good luck with it.

And you say you have a combi, so no hot water cylinder?

 

[cbrand]

I have a combi boiler yes, a baxi combi 80e.
Thinking whether to try fitting a new complete diverter assembly.

 

[cbrand]

What is the best way for me to flush out the boiler and central heating system of all/any luck please?

From British Gas website...
"Things we don't cover
Removing sludge or scale or repairing the damage it causes if we tell you it might be a problem for your system or boiler"

That might leave me a bit stuck might it not??

Got it sorted, called a plumber and he talked through how to best to remove the nut on the diverter manifold and try replacing the push rods inside the manifold. I could not previously remove that nut. I put in a new rod with some grease and it did the trick... woohoo!!
