Hello,
I have a 28 year old IDEAL gravity-fed boiler system, which we just had serviced. However, I now have great downstairs heat through the rads but no rads at all working upstairs. I've checked header tank (full) and closed off all downstairs rads, but upstairs barely gets warm. With downstairs rads open, upstairs all cold. I've also turned off all locking valves downstairs and still no heat upstairs.
I can't find a 'gravity valve?', only thermostat is on the boiler itself. Pump is turning, but I'm wondering whether this is faulty and not able to pump upstairs.
Any thoughts on what to try next?
thanks
Nick.
