The general and basic description of how a convection heater works is that it relies on the circulation of air within the room to heat the room. Air is blown over a heating element and then re-circulated.
These are the factors that decide for or against them…
- They are excellent at heating an entire room over an extended period of time.
- They warm a room much more quickly due to air moving constantly.
- Their heating element is covered by other parts, so even though these heaters get hot, they can’t burn you.
- They usually cost less than radiant heaters.
- These machines act in response to moving air. If a cold draft comes into the machine, then it takes longer to heat a room because the re-circulated air will not be as hot as other air in the room.
- Because they use fans, these heaters can overheat if the fan fails. If you have a model with any plastic in it, it will melt if overheating occurs.
- Objects anywhere near this heater, especially above them, can block the air flow in and out of them.
- There is higher energy loss with these machines because they push hot air up to the ceiling.
