Central Heating Pump

[Big Jim]

well whilst you're going to drain it to put the inhibiter stuff in, now would be the time to fit the t/valves as well.

They're cheap too... you can get reasonable ones for about 7-8 quid...

we've gone through that bit!

you're coming on at the end of a series of posts again without reading the previous ones salty!

Right I've fixed it !!!

 

I put the cleaner stuff in and within a few hours the problem went away, There's still a bit of circulation for a short time after the heating goes off but it soon stops. There must have been a blockage in the water heater section which the cleaner stuff has dissolved.

 

I got a price from my local plumb merchant for thermostatic radiator valves, £36+VAT

 

So I went to Homebase, £17

 

So I got some off the net for £7 each much better (thanks for the link Jim) and will fit them when I drain the cleaner out and put the inhibitor stuff in.

 

Now I can start concentrating on the car again

Well done .

When replacing valve see if the nut and olive from the old one will fit the new one.

Mine did not and had to cut the pipe off and fit a the new nut & olive as valve was bigger? you might have some movement up and down under the flloor as well.

 

 

Glad its sorted

Sorry Jim, had been following but missed that post...

Your probably find theres an anti gravity valve some where in the flow pipe above the boiler that has stuck open. The idea is in summer when boiler fires on its own for hot water with no pump the hot water can rise from the boiler up to the cylinder but not to the rads, then when you want the heating on, the pump overcomes the spring pressure in the valve allowing water to the rads. I would have thought probably the same in yours Jim. But the valves can be buried in the walls and all sorts and near impossible to find let alone change sometimes, so an easy solution is thermostatic rad valves and just switch them off in summer.
