A small increase in pressure is completely normal in your heating system, however, sometimes a system can become over pressurised. As your boiler heats up the water for your radiators and taps, the water expands. This is why you'll notice that your boiler pressure is different when the heating is off compared to when it is on.Get Price
The division of megapascal pressure (MPa) determines whether a boiler is low and high pressure. Boilers that produce pressure above 80 MPa are considered to be high pressure. Low pressure boilers have a MPa below 80 MPa. Water circulation can be forced or natural. If the water is pumped, it is forced.Get Price

One of the prime reasons why a boiler's pressure may keep rising is a fault in the expansion vessel itself. As touched on above, an expansion vessel is there to maintain pressure due to the expansion of gas and water whenever the system is heated. If there's a fault with the expansion vessel, the pressure in the system will not be regulated.Get Price
