Dimplex Duoheat DUO400I Radiator Heater

Very expensive to run, they dont hold the heat as long as the old type, the day time front panel needs to be left on all the time in temperatures below + 5 degrees. we bought this product because it was maintenance free. Runnig costs not to bad down to temperatures of +5 degrees. Have had the old type storage heaters without the front panel heat and found these to be better, heat wise and running costs.
