Hardly. All the calculations were done when we had a new boiler fitted. Recomended boiler size for a house with 3+ bathrooms, 20+ radiators and 4+ bedrooms is 27-40 kwh. Mine is within that range. We do have a largish sitting room, about 70 sqare metres floor area with a ceiling height over 15 feet. That takes some heating.[XAP]Bob wrote: ↑5 May 2023, 8:56amSo - you actually haven't even bothered to check how much heat energy you use...pete75 wrote: ↑4 May 2023, 10:47pmIt works from a hive controller so it does whatever that tells it to do. We get a regular oil delivery, pay by direct debit, the same as with electricity. I don't really monitor what either costs, they just get paid when due. If the bills were high I'd notice because they come out of the household expense account and we only put about £1500 a month into it. If that's not enough the bank will write and tell us it's gone overdrawn so we'll just put more in.
I suppose if I was a tight bâtard every cost would be monitored and cut back, but why go to all that trouble, worry and effort. It's only money and you can't take it with you.
You don't need to be tight, you just need to be one of the millions of people who have too much month left over at the end of the money.
With domestic fuel prices having risen to unprecedented levels, and businesses not even protected by the oft mentioned cap... saving energy is important to more and more people. Additionally, since we're screwing the planet over... you'd be better off sending that oil to a power station and using a heat pump - you'd get more heat into your house for the same amount of oil burnt (even ignoring the additional energy costs of delivering that oil to you).
I'd wager that the boiler is oversized by at least a factor of three.
The energy costs of delivering oil are covered in what the supplier charges per litre - I pay that.
I don't want more heat into the house, what we're getting now is quite sufficient. Why would I be better off using a heat pump? The boiler isn't very old, has a lot of years life left, the old boiler was 45 years old when replaced, and the cost of installing a heat pump system runs well into five figures. That'll buy a lot of oil, and the price is falling rapidly. The same can't be said for electricity.
