Gas boiler low pressure

masterboy123

Our gas boiler is not due for service for another 3 months.

But today I noticed pressure is 0.7 bar during functioning and when it's fully warm.

Manual says optimum pressure should be between 1 and 2.

Is there a valve that I could rotate until the pressure reaches 1.2 or so?

Pictures attached below highlighting the type of boiler and different valves.

Should be a fill loop or valve in your hot press, if you have one.

Mine looks a bit like this, blue plastic valve that's normally closed.

Thanks.

Our hotpress is on first floor and gas boiler downstairs in the utility room.

I can't seem to locate the "fill loop".

I turned off the boiler and waited 2 hours until all the pipes were cool. I opened up the valves (at the bottom of the boiler) but pressure wasn't moving at all 😔

The fill pipe will never be warm OP, my fill pipe runs up the side of the boiler like the one in the far right of your second pic, does that have a valve on it somewhere?

I checked the pipe on the extreme right, it is indeed cold and made of some plastic-rubber material, all other pipes are metallic.

But unfortunately no valve attached to this cold pipe. I followed it and it actually goes outside of the house (maybe for condensation or cooling).

I read the manual and according to that "filling valve" is located at the base of the Ideal Logic boiler. I tried those valves already and no luck 😕

When my boiler pressure goes low i open up the valve in hotpress and turn on the tap in the bathroom nearby and let the water run for 30 secs. This works for me every time. Pressure in boiler goes back up.

Thanks. Is your boiler located in the hotpress?

Thanks, its for me, gas boiler in the kitchen and hotpress upstairs.

could you tell me a little more about the valve you open in the hotpress? There are 3 red coloured levers, but I don't see any pressure-changing valve here.

Some pictures showing the pipework in the hotpress might help us to guide you.

I am attaching pictures from the hotpress.

I can't see enough of the pipework to help.

Need further out view of the all pipework.
