This oil filled radiator is great. As a 77, year old women I would not like to have to carry it very far, but it's not impossible to move it via it's handles to place where you want it. I'm using it in my lounge which is roughly 17 feet by 13 feet. I set the temperature at 20 when I'm ready to use the room and within minutes the room is feeling warm, after a coup[le of hours it can be turned off and the heater still keeps the room warm for about another hour. At present it means I don't need the central heating on in the rest of the house and am still cosy whilst reading or watching TV. I'm really pleased with this heater. It's sturdy, neat and easy to use as instructions are very clear. I also like the remotes control.
