I assume they are I think the heating engineer would know that bit ?
If the main hot water pipe sends hot water to the rads and then returns, would the return pipe be hot or cold if it is hot how does it miss the downstairs rads?

Hi
It only has the thermostat on the boiler, all trv's etc on all rads checked and working, the hot to cold happened straight away it was not gradual

Hi Guys
Thanks for the replies.
I don't think it is split, upstairs/down stairs.
The fault happened when one rad was cold down stairs, everything else working, we closed every thing down and flushed it through there was no water restriction through the vales, heat came to it, two hours later...
Hi All
I hope you can help.
The hot water is fine, the heating upstairs is fine, but rads cold down stairs.
We have flushed it through, put cleaner in it and flushed through, have had two heating engineers on it and none of them has fixed the problem.
Pump checked and working, no leaks...
