Oil radiators or Electric UFH

[Indoctro]

We are rural so no mains gas. We have a oil tank for radiators throughout our house plus the whole of downstairs and all bathrooms upstairs are fitted with warm up electric UFH

Our 1200lt oil tank is on average £500 to fill . Today it's £1500 due to what's going on.

We have never really used the UFH as just always assumed it's very expensive. But actually do you think it would work out cheaper to use at the moment than oil radiators.?

Anyone have a idea.? We don't have a smart meter so can't check that way.

Thanks a lot.

I expect at the moment, yes, it would be more affordable to use. That said, it entirely depends on how full your tank is. If you have plenty of oil, and you won't need to fill up again for the next 2 months or so, I would probably continue to use oil, but limit use and where jumpers. If you are running low and will need to fill up soon, yes, I'd use the UFH. Do you have any other sources of heat? We' also live rurally and we've been using our wood burners regularly as wood for us is cheap/free.

Is £1500 the cost of 1200 litres? I'll assume you usually fill up when there's a bit left in the tank - say you buy 1000 litres when you are down to the last 200 litres or so. If this assumption is wrong, the numbers will vary a bit.

1 litre of heating oil has an energy content of 10.35 kWh.

1000 litres of heating oil has an energy content of about 10.35 * 1000 = 10350 kWh of heat. If that costs £1500 it works out at 14.5 pence per kWh of energy in the oil.

Some of this will be wasted as the boiler isn't 100% efficient. Say it's 90% efficient, you're paying 16 p/kWh for energy from oil.

Electric heating is essentially 100% efficient, so you can compare this figure directly with the cost of electricity on your current tariff.

I'm paying 19.4 p/kWh for electricity, so the oil would still be cheaper for me.

Brilliant reply.

@CasperGutman thank you

It's cheaper to keep using the oil going by your calculations so that's what we will do stick with oil
