potterton promax?

I have to top my promax 24 he plus boiler up every day when the heating is on the pressure goes right up to 4 which means water is running out of the pressure relief and when it cools it is down to under 1 bar

There is no air in the expansion vessel which is either in the boiler or as a separate [red ] tank.To find out how check you tube [recharging an expansion vessel ]
