Unvented Heating system pressure increase | DIY

2008-11-21·I have an unvented heating system installed (in house when bought it) and it has developed a strange problem. Turned off boiler, left hot tank refill open (normal operation), removed cold fill to boiler system and watched the pressure in the boiler system increase from 1 bar to 3 bar when the pressure relief kicks in.

How do I adjust my boiler pressure properly?

Your boiler must be at the correct pressure for the hot water to circulate properly between the radiators, especially if they are on different floors.Generally, the ideal pressure is between 1 and 2 bars, but this may vary from boiler to boiler.Ask your heating engineer. Check the pressure gauge. A quick look at the pressure gauge is enough to check your boilers pressure.

My hot water boiler keeps increasing pressure when it

My hotwater boiler keeps increasing pressure when it runs. Normal pressure is 12psi but it has risen to as high as 40psi though the max pressure is indicated as 30psi on the gauge. I rcently replaced the flow control value which I set to the normal 12psi prior to use of the heater. The house is dual zoned and the problem occurs in bith zones.

Boiler Losing pressure? | Specialist Boiler Services

If your boiler/heating system is losing pressure, there are some things you can check to diagnose the problem for yourself. Check around your radiator valves and bleed screw for any signs of water, while your at it bleed them, as air in a system can cause your water level to drop. Check for any stains on the ceiling, as this is evidence that water is leaking through pipework.

How to Reduce the Water Pressure to a Boiler | eHow

2019-7-23·How to Reduce the Water Pressure to a Boiler. The normal water pressure of a boiler should be between 1 bar (a unit of pressure) and 2.5 bar. The boiler pressure will normally rest at 1 bar when cold and rise to 2.5 bar when in full use. On many newer models, the boiler will be equipped with a cutoff switch to prevent damage to the heating system;
