Climate Heat Transfer

Sharing the heat from your wood fire

Heat transfer systems utilise heat from your wood fire to warm up other rooms in your home. A heat transfer system is not a central heating system, but rather a way to use heat that would otherwise be wasted. The heat that moves through the system won’t be enough to completely heat other rooms in your home, but it will be enough to take the chill off.

How heat transfer systems work

Wood fires don’t have a thermostat to regulate their heat output, making them an uncontrolled heat source. As heat rises, it accumulates at ceiling height. The accumulated heat can reach temperatures of 35°C and serves very little purpose at this height. A heat transfer uses ducting, which is installed in your ceiling space, to move the trapped heat into other rooms of your home. This type of system is most efficient when it is used to heat no more than three additional rooms.

Components of an efficient heat transfer system

Not all heat transfer systems are created equal. At Climate we pride ourselves on providing the best products to our customers, which is why we only sell and install certain types of heat transfer systems. The best heat transfer systems have the following components:

  • Thermostat: The thermostat will be set to a switch-on temperature (for example, 21°C). When the air in the room heated by the fire reaches that temperature, a fan switches on to draw the excess warm air out of the room. If the room drops below the switch-on temperature, the system stops transferring heat until the room heats up again.
  • Insulated ducting: Quality insulated ducting is a key component in a high performance heat transfer system. This prevents warm air from cooling down before it reaches the other rooms.
  • Ceiling grilles: It’s important that the rooms being heated have the appropriate type of ceiling grilles installed, as this helps warm air mix with cold air more successfully.
  • Fan: A system with a high quality fan will help transfer warm air quickly and efficiently. The fan must also be the right size to handle the amount of air that needs to be moved through the system.
  • Fan speed controller: This allows you to regulate the speed of the warm air as it travels through your system.
