Choosing the right wood heater

Major factors to consider when it comes to choosing a wood heater are:

  • Size of your home
  • Building layout
  • Number of rooms you’d like to heat
  • Your priorities between aesthetics and efficiency


Designed with an air cavity between the firebox and the outer skin. This means that the air in the avity heats up, expands and rises, drawing more air in from below and forcing the hot air out through the top of the heater. A good clean burn convection heater can produce over 3 cubic metres of heated air per minute.


Radiant wood heaters have all sides of the firebox exposed. They are designed for heating large open areas where heat can travel in straight lines. Ideal for rumpus room areas or large open plan homes.


Fans will help circulate larger volumes of warm air, breaking down the layers of hot air that collect at ceiling level. Consequently a wood heater with a fan will heat a room faster than a conventional heater.


Check the construction quality of the firebox, as this is the engine of any wood heater.
