I don.t think you get fumes from electric storage heaters, you may be suffering a little dryness of the skin etc, it is common with all sorts of heating when they are on for long periods of time like the long winter we i having at present, up to a point central heating is not healthy. Years ago you had one coal fire in your main room, if you could afford the coal that is, the rest of the house was freezing but a lot less colds and flu around, turn the heat down wear a jumper and also save money.
