Everyone deserves a warm comfortable home
that's the Deflecto difference
Keep warm this winter with our Heat Transfer Kit

Our Heat Transfer Kits

The Heat Transfer Kit utilises and redistributes existing warm air from a room that has a single heat source (such as a fireplace or potbelly stove), to colder rooms around the home using an inline fan.
Gradually the Inline fan will warm the colder rooms creating a more temperature balanced house.

We strongly suggest that a qualified electrician install one of our heat transfer kits.


Provides a warm environment throughout winter for you and your family.


Fan costs under 5¢ to run per kWh *based on HTK2 inline fan


The inline fan shuts off in the event of an electrical fault.


3 kits available

Designed for safety, the kits come supplied with Australian Standards (AS/NZS 4859.1) approved fire-rated insulated ducting and the inline-fan shuts off in case of electrical fault.

The fan should be positioned 2/3 distance from the inlet, making sure the air flow arrow is pointing towards the outlets.

For optimum efficiency the inlet should be located 2 metres away from the heat source.

No – the kits are only designed to transfer existing warm air from a room and should not be directly connected to the heat source itself.
