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
Jan 09, 2011 · Boilers - Home Heating Steam and Hot Water Systems - What should the pressure be on a Buderus boiler when heating up - A couple of weeks ago I woke to my wife telling me the boiler was leaking, it turns out the relief valve was leaking.

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
