We have a combi boiler, heating is set for morning and evening. I may pop it on in the afternoon for an hour if cold.What kind of heating have you got?
Do you have the heating on a lot?
Do you use the oven/tumble dryer a lot?
Do you run hot water for baths or showers a lot?
Try turning the heaters on each room off unless desperately needed - we don’t have any of the bathroom heaters on in our house and rarely have the kitchen one on. We don’t have a tumble dryer and don’t have baths very often.
We only have showers. No bath on the property.
My oven is used but not excessively. Just to cook dinner.
Yes my washer is on daily. My dryer is only used in winter mnths. But my other house was much later. Makes no sense.
