Had the service and the engineer said the working pressure is too low. When running at maximum, the pressure at the boiler is 17.5mbar. Pressure at the meter is 17.75mbar.
Standing pressure is 23.5 at meter and 23 at the boiler.
So I fished out the manual for the boiler and it says both standing and working pressure must be at least 20mbar. That doesn't make much sense to me as surely if the standing pressure is 20 then full whack working pressure would be lower than that?
Anyway, is this an issue for the boiler warranty or an issue for the gas supply? There are no other gas appliances like a cooker in use.
Boiler appears to runs fine and hasn't been permanently disconnected at the service but still a bit of a worry.
