Low Pressure In Heat Only Boiler

HarryG1995

Hi all, wondering if anyone can help me to identify the filling loop in my boiler setup.

The Glow worm heat only boiler is located in a cupboard in the kitchen and has an external pressure gauge which is showing a value of around 0.6 bars. There is only 1 yellow valve on the bottom of the boiler and no clear filling loop.

We also have 2 tanks in the hot press upstairs but no clear valves that I can identify.

Any help would be greatly appreciated, thanks.

I would have expected to see a dial gauge in there on the pipe as when you turn on the tap it adds more water and then turn off water.

Okay thanks for taking a look, a dial gauge in the hot press itself?

Yes as on that pipe in hot pipe are 2 levers which i open and dial gauge rises due to water pressure filling it up more. Then where my gas boiler is another gauge which should match the same pressure.

Okay thanks. Upon further investigating there are additional black circular handles on the pipes circled on the left and right. The pipe beside the pipe with the black valve on the right seems to be the warm water tap. Could not find a pressure gauge though

I wonder if any of those taps are turned off ? Normally feed pipes are 1/2" and connected to a mains pipe possibly from a split up to the cold water tank.
