SOURCE: heating pressure gauge goes up

yes tami
there should be a pressure rellief valve fitted.
it also sounds like the heat exchanger is blocked if the hot water is not as good as it used to be and the boiler reaches temperature too quickly then there is scale in the heat exchanger and needs to be cleaned or replaced

SOURCE: 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.

How do I decrease the pressure on an heat line monza 24 boiler


There will be a pressure release inside the boiler cabinet......but the easiest way would be to bleed the radiators till the pressure is at the right level!

My boiler loosing pressure when off and pressure keeps rising when heating on


The system is low on water. So now instead of water you have air in radiators which is easily compressed when it heats up. Then pressure loss when it cools down.

Add some water to your system until you have 15lb pressure and bleed out upstairs radiators at the same time.

Loud noisy boiler what's wrong with it ?


Hi. I'm not an expert but most of my boilers in the past get noisy when they get air in the system. Underneath your boiler will be an inlet tap to top up the sysem with water. Make sure you bleed all of your radiators of air till they squirt water then keeb topping up the system and bleeding till no air remains in any of the radiators. There should be a pressure dial on the front of your boiler and there is usually a red fixed needle which shows what the opperating pressure is. I would do this before anything else and see if this solves the problem. :-)

Hi there. Our valiant boiler doesn't seem


Lack of pressure in the primary circuit [radiators] Look for a pressure gauge should read between 0.5 & 1.5 bar
Somewhere there is a tap/valve/pipe connection to refill & looks like a small thumb turn or a screwdriver turn on a connection on the mains water inlet pipe. turn on until you get the right pressure then off

Low pressure on recently serviced Vokera 14/48se.


Identify the cold feed to the boiler, then look for a tap/service valve which when turned lets water into the boiler via a fill loop to pressurise it. 1-1.5 bar is ok

I have a Glowworm 30 cxi and the light is flashing, the pressure is 0.4.... i have no water or heating...help please


Under the boiler a little right of center there is a blue/other colour knob. Turn this anticlockwise [as you look up] [twist from right to left] This is the mains inlet tap to let water into the boiler and create the pressure shown on the guage 0.5 bar is the absolute nin.
allow the water to flow in until the guage reads about 1 bar then turn off the knob -not too tight as these are plastic
If you allow too much pressure- do not worry, there is an automatic relief valve.
If the boiler persists in loosing pressure, look for a leak in all pipes to & from radiators. If no leak then check the pressure relief valve outlet pipe, it usually goes through the wall to the outside. Look at the end for water drips & if there are drips replace valve

Boiler keeps losing pressure when the heatings off


Hi Leehardcast,

Yes the problems are related. The system is low on water. So now instead of water you have air in radiators which is easily compressed when it heats up. Then pressure loss when it cools down.

Add some water to your system until you have 15lb pressure and bleed out upstairs radiators at the same time.

Please rate this response and Good luck, Phil
