Central heating is much more effective at maintaining a stable temperature over a longer period, whereas the heat from an electric heater will soon dissipate if the rest of your home is cold. Nearly all have some kind of carry handle for moving about and many have a safety cut-out feature, which will switch off the heater if it gets dangerously hot. They tend to be cheap to run, but some can be really slow to heat up. Most oil-filled heaters are also fairly heavy and cumbersome, so look out for models that come with wheels.

Cold air setting Some fan heaters can help cool you down too. They're not nearly as effective as a dedicated air conditioner, but a light breeze of cold air is better than nothing.
