Heat Transfer Kit Features Overview:

Installation Typically in Ceiling Cavity
Extraction Rate 580 m3/hr
Noise 45 dB(A)

Ductable 18m of 150mm insulated duct

The Heat Transfer Kit system uses a ceiling vent in a particularly warm room and an inline fan to transfer it, through insulated ducting, to a vent that opens onto the room that requires further warming. The Heat Transfer Kit provides an energy and cost-efficient way of moving heat around your home. These kits can also be used to circulate cool air in the summer.

How the Heat Transfer Kit works

Warm air is picked up, usually at a high point, using a ceiling vent in the source room and the fan transfers it to the vents in the destination room or rooms. The fan is usually turned on via a wall switch (not provided) in the source room. An alternative is to use a thermostat (optional) so the fan comes on after the source room has reached the set temperature, and will go off if the temperature drops below the set temperature or if manually turned off. Vents in the destination room (or rooms) are ideally placed furthest from the door. This way the cold air is displaced out of the room and ideally will return to the source room to be heated, then transferred to the destination rooms and the cycle is repeated.


The kits can be installed by the client as it is relatively easy to install. Some handyman skills are required to make holes in the plaster, etc. An electrician is needed to provide power to then fan (or a power point) and a switch, also to install a thermostat if required. The electrician can also install the system at the same time. The fan is provided with a lead and plug, so it can be plugged in to an available power point which an electrician could install independent of the system installation. An optional thermostat is available (see accessories below). PLEASE NOTE: an electrician is required to instal a thermostat.

The thermostat is usually placed in the room with the warm air and will turn on the fan once the room has reached the user set temperature. At this point the room is assumed to be “too warm” and it is time to transfer warm air to other rooms. The fan will stop running if the temperature drops below the set temperature. The thermostat can also be used when transferring cold air, in that case settings and behaviour will be in reverse ie once the room is too cold, the fan will operate and transfer cold air to the other rooms.

Please Note:

These heat transfer kits are designed to move air slowly from a warm room to other, colder rooms and the aim is to take the chill out of the destination rooms. We aim to achieve about 6 changes per hour in each destination room, assuming a 25m3 per room. The idea of a heat transfer system is to take the excess heat, not all of the heat. Taking too much warm air from the room with the heater will most likely make it cold, as the heater is generally over-sized for the room but not designed to do many more rooms. A heater and heat transfer kit will work quite well in most situations but it is very unlikely to be as effective as a central heating system.

    Ducting needs to be longer, my house isn’t that big but the bedrooms are spread out.
