I have repressurised my Baxi Combi Condensing boiler (thanks to Stan). What I forgot to mention is that when my boiler begins heating the pressure gauge falls and then returns to normal when the boiler switches off. Baxi told me that the pressure gauge should in fact rise when the boiler is heating as the water expands.
Can any kind person suggest a reason why the pressure gauge falls instead of rising?
Very many thanks in anticipation.
