Combi boiler advice

Combi boiler pressure gauge reading zero
Hot water and heating system works fine. Pressure gauge reads 1.5-2 bar when heating is on.
Should I get this checked out :?:

Different boilers / system sizes work on slightly different pressures.

Rough average is 1 to 1.25 bar cold. It will go up a bit as the water heats up and go back down a bit when it cools down.

If you are topping the pressure up again within a week then it needs looking at.
Prob either a pressure vessel pressure top up or if it keeps going down then a new pressure vessel.

Can be other things but thats the likely cause.

Standard call out to top up the pressure, probably £150 to £230 ish to renew it depending on model.

Sounds to me like it's just a duff gauge display. For safety a combi boiler will turn itself off at under 0.5 bar so if your's is truly at 0 bar it would never come on.
