Most energy efficient electric heater?

    Hi all, I'm just after moving into the coldest and oldest house ever. My room is quite small though so I think a smallish electric radiator wouldn't break the bank to run. What's the most energy efficient/cheapest electric radiator out there?

    Hmmm I'd not bother with a rad they take their sweet time to heat and become effective
    spreading the heat, look for a fan assisted convector heater.

    You asked for a recommendation for an 'energy efficient' heater, I don't think there's any such thing as an inefficient electric heater - what you spend on electrical energy you get out as heat, there's nowhere else for the energy to go. It's not like a gas central heating boiler where a large % of the heat can go up the chimney and be wasted.

    Actually, a fire insert type electric heater, looses a % of it's produced heat to the chimney, hardly as efficient as a free standing electric heater? So, in fact, there is a difference.

    The innefficiency is due to location rather than the heater though. So assuming the OP gets a heater thats not in the chimney, the running cost will be the same for a given kw heater over time.

    Any inefficiencies are caused by heat escaping, house insulation etc, rather than by the heaters heat production efficiency.

    Absolutely, no argument from me there.

    Just to remember I was replying to this comment
    ....It's not like a gas central heating boiler where a large % of the heat can go up the chimney and be wasted.
    by saying that a large % of the heat produced by a particular electrical heater can also go up the chimney and be wasted.

    Another point I would like to clarify here is that this point
    what you spend on electrical energy you get out as heat, there's nowhere else for the energy to go.
    strictly speaking is not entirely accurate. For example, if you have a fan assisted electrical heater, some of the electrical energy spent is used to keep the fan operating instead of producing heat.

    Yes id agree with all that.
