What is so good about an oil filled heater?
In a couple of words – durability and control. Yes they are relatively large and heavy, however as they are in fact small vessels full of oil, they have to be made of steel and are very tough. There is no reason why they won’t last for decades. Depending on the model they are also very controllable. A 24 hour timer and thermostatic control provides a far greater degree of control than, say, only two or three heat settings. With frost protection setting they are ideal for long term protection of heating systems in dormant properties, as well as furniture and other contents. With this sort of control (i.e. stable warmth vs. harsh on and off heating) comes operating economy.
