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.

Baxi boiler 80E low pressure on boiler how to fix it?


Silver flex hose may be the (correct) filling loop. There may be a valve at each end of it, maybe just one at one end.
Open the single valve slowly and LISTEN for the sound of water entering the system, and LOOK for signs of the pressure gauge rising.
On the dual valve version open the first, then open the second slowly as above. Close both valves when pressure is adequate. Adequate is determined by the specifics of your system, but note that more pressure DOES NOT mean better showers, etc.
It should only take a few seconds to top-up, any longer indicates a significant loss of fluid from the system.

My pressure is low on my halstead eden cbx24 boiler, i can find the loop to fill it up but dont know where to put the water in, can anyone help?


Do you have a sight glass that shows water level in boiler on this loop? If so is it marked where normal water level is supposed to be? There should be a water line connected to boiler with a valve on it. This will be a manually operated valve unless it has auto fill control. Locate this valve and slowly add water until level in sight glass is back where it should be,then shut valve.While you are doing this the boiler should be at operating temperature because hot water expands and you don't want to overfill. There should be a temperature and pressure relief valve on top of your boiler to prevent unsafe conditions but I wouldn't count on it working properly if it is very old. My main concern is for your safety so if you are unsure of something don't do it. If your boiler has a automatic water make-up on it then you need to have a service tech. find out if it's not working,and repair or replace it. I hope this helps you. Thanks

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.
