Boiler Pressure - Free Heating Advice
If the boiler pressure is only raised to 1½ bar, with the system cold no water enters the expansion vessel as the water pressure is not enough to compress the air within the expansion vessel. However, as the system heats up, the water pressure will increase and water will start to enter the expansion vessel, compressing the air pocket on the other side of the diaphragm.
