"I have had these heaters for a few years now and ordered another two for my elderly parents. They are really good for taking the chill off a room and extremely reasonable to run. I would statethat most normal size rooms need two heaters and they need to be on for a few hours before you are using the room to benefit from them; obvioulsy a timer could be fitted to the plug. Screw fix are by far the cheapest for this product"
"Mounted on wall below north facing window - fitted a room thermostat by the door to the kitchen .Comes on overnight and is perfect when the temperature drops - much better with the additional thermostat! Neat and unobtrusive, sound purchase ."
