It's a combination boiler.

That's how they work.

Sorry my heating is not working at the moment but the hot water is pressure is on 1bar (black arrow) but the red arrow is on 3 is this causing it?

 

[Dan Robinson]

No.

So which is it?

Your boiler can only do one thing at a time.

Sorry my hot water is working but my central heating is not, my pressure is fine and I am using a Honeywell thermostat which is set on continuous running for both at the moment

Usually leaked water from the spindle of the hot water proving switch into the microswitch causing a permanent demand for hot water.

Thanks does it mean I would need a callout or is this something I can fix myself?

 

[Dan Robinson]

Judging by how this thread has developed I would say call someone in.

Do let us know what the fault was though!

 

[Hpsauce83]

Ollski how do I fix the constant demand for hot water? Would I need to change my zone valve actuators for the heating?

 

[Dan Robinson]

 

[Hpsauce83]

I changed the valve but still the valve for the heating doesn't open

Help?

 

[ollski]

What valve?, compact is a combi boiler
