A fan heater can heat a room quickly. This is because the heat produced by the heater is pushed into the room by a fan. This heats up a room much faster than other types of heaters. This makes a fan heater perfect to have on hand for quick access when it is cold.
Thanks to its built-in fan, a fan heater can heat up a room at lightning speed. One drawback is the noise the fan makes. This is obviously not nice to hear all day long. This makes fan heaters especially nice to turn on briefly to quickly heat up the room. A fan heater is therefore ideal as additional heating.
One type of heater that does well to be on all day to continuously heat the room is a convector heater. This is heat just like from the central heating system, but electric!
