BOILER RE PRESSURISING

[altafica]

My boiler needs replacing, I know, but due to finances I have been trying to keep it going. I have to repressurise it every night, to ensure it starts in the morning. The heating is on all day.
Question is, does repressurising use significant more gas? The units I have used this quarter have more than doubled from this time last year, with the same timed usage.
I have a Heatline boiler I can hear the groans from here I inhereted it I may add, and had a PV ? valve fitted about 2.5 mths ago. This
Thanks

Re pressurising uses no gas at all

Have you investigated why it is loosing pressure? Could be you have a leak.
