Hi everyone :)

I just moved house and on the first night in the property I activated the heating using a Honeywell thermostat. Didn't take note of which radiators worked but downstairs definitely heated up. Yesterday downstairs hall was working but living room wasn't. Upstairs hall wasn't working so I took off the knob (not very technical sorry!) and pressed the pin up and down. This got it working. Today there's heating upstairs including upstairs hall but nothing downstairs. Pipe going into radiators downstairs are warm but not as hot as radiators upstairs.

Any ideas? Really could do without added expense this month ::b

Could several things.

Make and model of the boiler first.

Is it a combi or do you have a cylinder.

What is the boiler pressure when cold.

Where is the boiler.

In that case it may just be a balancing job, first check all the TRVs are working and on full or remove the heads. This time of year they may be closing from the room heat.

Check for air in the radiators and top the pressure back to where it is if it falls below 1.2 bar

Could also turn the upstairs rads off to see if any air moves in the pipes.

Have you turned off all the working radiators.

If so turn the rest off bar one and see if it clears.

Has the property been empty for a while, still sounds like air or dirty system

you need all the up off, swap the one on down in turn.

You may want to drain the system and re-fill, perhaps flush it with a hose pipe if your happy to do it..

Are you sure the TRVs and lockshield valves are open.

What size pipes are feeding the radiators.
