Very roughly - the kWh rating of the rads x the number of hours that they'll need to be on.How do I calculate the likely cost of running electric rads or electric heaters?
Back of envelope calc, take your current oil spend and double it, minimumHi. My oil boiler is very old and will need replacing soon.
I would like to get rid of oil altogether. The house is old and not fit for a heat pump. So I was looking at electric rads or the Aeno electric heater or similar.
How do I calculate the likely cost of running electric rads or electric heaters? It us a 4 bed semi-d house, so would need electric rads or electric heater in 4 bedrooms, hall, and 3 downstairs rooms.
Thanks in advance for any help.

You know how much batteries cost, right? Few can justify buying them, unless they are willing to endure a 20-30 year payback.If you do want to stick with electrical, get solar and a battery installed and get a long term payback towards electrical heat
Don't - the size of an electric radiator big enough to heat a room would consume far more energy. The only way to use it efficiently is via devices with an inverter like air-to-water heat pumps which produce more heat than they consume. Some air conditioning companies have multi split systems but these are not cheap.Hi. My oil boiler is very old and will need replacing soon.

He could also look at multi split air conditioning systems primed for heating such as those from Hitchai or Daiken. They work similarly to heat pumps but still would fear there would be huge difficulties in heating a house so large sufficiently.Check out "EV Puzzle" youtube channel, he's ran a winter test using electric heaters and not using oil for a month to see how he fared.
He has gone air to air more recently, you can check out those videos too....Electric vs oil heating - No central heating all winter. Results of my full winter test
A full winter without a boiler using just electric heaters.Time to summarise the test and results. A fruitful exercise to learn what it's like without a cent...youtu.be
An air to air heat pump might be still worth checking out as it's a lot more efficient and there are models which can do hot water too but small tanks like 90l/120l as these are targetted at apartments. But given the size of house, it's probably going to be disruptive getting them installed where they need to go? You will pay more for electric heaters in the long run - vs up front A2A.
If your boiler is old but still working, i would focus any investment right now on acheiving the maximum level of insulation possible.Hi. My oil boiler is very old and will need replacing soon.

Replace the boiler and put in more insulation in the house. Changed an oil burner there in a house down the country a few years ago and saved at least one amd a half to oil fills per year. Did not use sei scheme and saved about €2k.Hi. My oil boiler is very old and will need replacing soon.
