    i hope this is on the right forum - just wondering if anyone has done the sums on comparing the use of oil heating versus electric fires and a coal fire to heat a three bed standard house. We currenly use a coal fire (with no back boiler) and oil heating to heat children's rooms. Trying to work out if we would be better just using electric fires and the coal fire economically or just oil altogether...any ideas

    there is 10kwh of power in litre of oil assuming 70 cent a litre and old boiler working at 70 percent efficiency =10 cent per kwh esb =16 cent per kwh if you have a new boiler the efficiency could be 90 percent which would drive the cost down even more oil will always be cheaper

    Yeah, oil is definately cheaper. SEI (or is it SEAI now?!) have a comparison table somewhere amidst the mass of stuff on their website. Think of it this way -> electricity in this country at least is mostly generated by burning fuel in the first place which has losses associated with it and then it gets distributed everywhere with further losses involved. Burning the fuel directly in your own boiler is the way to go... Interestingly though, central heating systems have their own losses through pipes etc. etc. but I presume these are minimal.

    I'm using about 11litres/day of oil in this weather especially with the kids off school. That equates to about €7/day in oil plus the energy required to run the system.

    Not sure how that equates to electrical power

    FYI I would think the electrical power consumption for running a system is typically 100-200W (boiler and pump). Are you actually measuring the oil consumption? If so, what product are you using out of curiousity?
