My wife has a garden studio for her work. The cost of heating the studio in the winter is truly grim these days. Albeit well insulated it gets very cold. Usually she uses a 2Kw 'blower' heater; very good but the moment the door is opened, the studio gets cold again. This small oil filled radiator (on lockable wheels) is absolutely ideal. Reason being; the radiator stays hot for quite some time instead of just going off and the cold returning! Great bit of kit and well priced for what it does. Absolutely love it. Now where's my £500? I am a poor pensioner you know!!
