To reduce the pressure there is a dark red knob at the bottom of the boiler to the right turn this and the pressure will start to reduce . but this is not a fix there is a reason for the pressure increasing and needs to be addressed .

As is the case with mostyou can not decrease it...if it gets to high the t&p should come open and drow the pressure with out you doing anything. But just in case post the name and model of you unit and I can give more exact info on it.

AMTROL WH7P-41 GAL TANK. 12 YRS OLD. BOILER PRESSURE IS INCREASING ABOVE 30PSI, AND DUMPING SMALL AMOUTS OF WATER FROM RELIEF VALVE ON BOILER. Do I replace coil?, or buy a new tank? Thank you


do you have a pressure tank as part of your water heater and water pipes? if yes, check to make sure tank pressure matches your incoming water pressure from your municipal hook up

Why does the pressure rise to over 3bar when the central heating is in operation ?


3 Bar = 43.5 PSI When you heat water it always expands increasing pressure.
In a closed vessel volume can increase by 2-3%. Either expansion tanks allow for this and PSI is maintain or without an expansion outlet the PSI will increase in proportion to heat supplied.
Is this a low temp hydronic boiler operating at or <140F, a hi temp hydronic boiler @ >180F or steam boiler?

Hi, your boilers pressure should be holding 1.5 bar with the relief set about 3. If the pressure is below this the flow switch will cause the boiler to stop as theirs not enough pressure to operate. Another thing, does your boiler have an auto fill system or do you need to plug a hose in to fill it? If its an auto fill system and you lose pressure you could have a leak.

Your boiler has an expansion vessel that is like a bladder full of air. Yours has lost it's air pressure. Check your manual for this vessel and where the valve is to re-inflate it and what pressure to inflate to. It should have a simple tyre valve, pump it back up (usually to about 1 bar after releasing the water pressure) and should be all fixed. If you can't re-inflate the bladder is holed and the expansion vessel will need replacing.

Pressure is ok? at 1 bar or above
I think on this one there should be a reset button [red] on the left hand top of the casing - or lower the control panel [ phillips screw on each side] and the button is on the left of the base plate. Press this and try the heating.or hot tap
P.S. if you're on a prepayment meter check you have gas.

Sounds like the expansion vessel in the boiler has lost pressure or is faulty. If you have a tyre pressure gauge, locate the expansion vessl and check the pressure via the schraeder valve. It should be around 1.5 bar. If there is no pressure you can re pressurise it with a bicycle pump. Should it not pressurise then you will need a new one. The pressure relief pipework outside is damp because the system is over pressurising at relieving pressure at 3 bar. This obviously causes a system pressure drop. You can install a pressure vesel into the heating return pipework should accessing the boiler be difficult.

I can't turn the bar pressure up on my Vaillant VCW 221 Boiler


on the pipework below there may be a silver braided hose with one or two valves on the end. turn the valve(s) so the handle is inline with the pipe this will allow water from the mains supply into the heating circuit , remember to keep an eye on the pressure gauge. fill the system to 1bar cold then shut down the valve(s). turn on the boiler and it should be ok, if you lose pressure again then you may have a leak somewhere which needs to be found.
