upstairs radiators not heating

gambit83

any advice welcome: the radiators upstairs aren't heating but are downstairs

they were working upstairs a few weeks ago when they were first put on after the summer

when i looked at the pressure valve it was low so i brought it up hoping that this would fix the problem but it hasn't, nor has bleeding and balancing the radiators and the pump

any other ideas how to fix it before i ring the plumber

main on/off switch

then a separate upstairs/downstairs switch

thermostat radiators

Have you checked the thermostat is calling for heat if turned up high enough?

Can you manually override the switch that's controlled by the thermostat?

there should be a small lever on it that can be manually opened. try that.

Example image just from google

Assuming you have been getting water when bleeding upstairs rads, find the motorised valve that the upstairs switch controls and use the manual lever to turn it on.
Turn on all your zones and the valve that gives a lot of resistance on the manual lever will most likely be the upstairs one.

The motorized valve will look like one above or have a white or yellow plastic cover instead of the metal one above.

thanks for your replies

tried that but still no joy

Is there a light on the motorised valve?

When you turn the thermostat up to full does it come on?

it heats when the radiators are heated (from the oil)
yes the hot water cylinder is upstairs

Does the copper cylinder water heat when you turn on the upstairs zone.You will know if the flow and return pipes to the copper cylinder are getting hot.There should be a balance valve on one of these pipes

apologies for my late reply, was away with work

it would appear to be

another problem now, the water isn't getting hot anymore, tried to attach pics of the pipework upstairs and downstairs but not linking properly

any suggestions most welcome, I'm thinking its prob best at this stage to call a plumber

It's a problem, call a plumber, I don't think any online advise can help you at this point.
