I watched with interest the "power saving" item on One News, 31/5. however I was somewhat aghast at the few seconds on heating, specifically the comment that the "fan heater was the most innefficient" and that "for a room this size an oil heater would be better".
I suggest that the reporter AND the so called expert take high school physics again. By definition, all electric heaters are 100% efficient, that is all the electricty in eventually comes out as heat. No exception. For the same amount of net heat given, an oil heater and a fan heater will use exactly the same amount of electricity. To say otherwise is stupid beyond words.
If they'd suggested a heat pump that would have been fine, heat pumps are not electric heaters and can move heat into a room more efficiently than a heater can create heat.
