Downstairs rads not heating

ra0044

Hi all,

Hope someone can help me out with a problem i am having with our heating.

Basically we have a three storey house with rads on 2 zones. Zone 1 is kitchen and hallway and zone 2 is first and second floors. Both zones are controlled by thermostats and control valves. Boiler is a Potterton and is in the kitchen

The problem is that I cannot get the kitchen and hallway rads to heat if the rads on the top floor are on. I have tried turning all the rads off and starting with the kitchen turning it on and letting it heat up before moving on to the hall and the next etc. and they will all heat up but the next time the heating comes on the rads in the kitchen and hall stay cold.

I have also removed the control valves to ensure the valves are fully open.

We haven't used the rads in the kitchen or hall for a couple of years as the kitchen overheats with the oven on and cooking etc but the wife now feels the hall is to cold and wants at least that one on.

Really hope someone has some ideas.

THanks

You need a plumber to balance the system and fit a stronger pump
