Convector heaters are cheap to install, but they tend to be an expensive method of heating your home – whether filled with oil or not. Air passes-over the electrically-heated elements in the heater. The warm air then fills the room, either naturally by convection, or with an electrically powered fan. Convector heaters are costly to run, but they can provide heat quickly. They do not, of course, provide hot water and therefore a standard immersion heater or other water heating system would be required to run alongside them.
Pros: Relatively cheap to install.
Cons: Expensive for homes that need to be heated a good portion of the day or that have a poor energy rating.
