Heating and hot water - best case £4.68 per day, worst case £9.03 per day.
Electric, £3 a day.
So, best case £238 pm, worst £372 per month.
Plus wood, kindling and firelighters. Idk how long those will last as we have changed our heating patterns. Those cost £148. Might last two months, I guess, maybe three? Wood is currently £100 per cubic metre bag, and last winter we got through four.
Yeah, let's not add those to the total.
We are in a 2400 sq ft detached house on oil. It's 11 years old. We have VERY high winds. We are both at home all day.
The price of heating oil fluctuates between 72p and 86p at the moment. We use twice as much to heat the water in winter than we do in summer. We use 40% more on heating in January than we do in November.
Heating our water uses 2/3rds of the oil cost because we are heating an entire hot water cylinder instead of using a combi. In winter it has to be heated twice a day instead of once.
Half the ground floor is heated to 21 degrees for six hours a day (no, we can't leave it on lower all the time, our house and systems are designed stupidly and it literally sets the ground floor on fire as soon as winds pick up, which is very often).
Half the upstairs heats to 20 whenever the TRVs get below that. The other half we don't have switched on. All the bathroom radiators (x3) are switched off.
... There are two of us! BUT, we are both at home all day, which generally adds about 40% to a heating bill, in terms of how an EPC is calculated anyway.
I don't own a tumble dryer and do about six washing loads a week.
We can only cook on electric.
Got romantic notions of moving to the countryside in a big open space? I hope you have deep pockets. The grand total for last year was 3.8k including a huge amount of wood and fire supplies, but probably £600 of that was through having the immersion permanently turned on for the first two months we lived here.
Don't do that.
I fantasise about combi boilers and gas supplies.
