Hi, have an ideal Combi boiler, we believe is only a couple of years old, the pressure had dropped on the CH system so the wife attempted to fill the system, unfortunately she opened and shut every valve under the boiler until something worked, the pressure is now good and the boiler appears to be working fine but we have no heating, one double rad gets reasonably warm, the rest in the bungalow stay cold, I’m guessing that the water isn’t circulating around the system to warm all the rads? Can someone clarify, if stood looking at the boiler, there is a pipe going in to the far left that carries the pressure gauge and a shut off valve, should this valve be permanently open or shut?
Ps. I’ve attempted to bleed all the rads but there seems to be no air in any of them.
