We have a Baxi solo 3 PFL 30 boiler. The hot water is working ok and the boiler fires up for this no problems. The problem is that we cant get any heat to the radiators. They have all been bled so there is no air lock. Our boiler doesn't have a pressure gauge that i can see. Has anybody else had this problem and if so how was it cured ? This is the first boiler I have seen that doesn't have an obvious pressure gauge.
