Our heat transfer systems are made to the highest standards with high quality components, including European VENTS fans.
Use the excess capacity of your heat source to warm other rooms in your home. An average size lounge requires 2-4 kw of heating, yet heating appliances such as log burners and pellet fires* can generate 10-20kw. That’s 5 times the amount of heat required for a lounge room. This leaves an excess of 8-16 kw of heat available to warm other rooms in your home. Air trapped at ceiling level can reach temperatures in excess of 30°C so .
- Improves energy efficiency.
- Easily installed by a handy person.**
- Thermostat or speed controllable.
- Constant Air Movement reduces the risk of dampness.
- Quiet powerful fan.
- One, two, three or four room kits available.
- Low power consumption (80 watt).*
* Please talk to us before using with a Heat pump, or scroll down for more information.
** We recommend using a registered electrician to wire the fan.

Operation
A ceiling diffuser is installed in the ceiling at the highest point or near the opposite side of the room to the heat source if ceiling is flat (and not within 1m above heat source).
Ceiling diffuser/s are installed in the room/s requiring heat, to distribute the warm air.
A fan with ducting moves the air from the heat source room to the cooler areas of the house.
A wall thermostat (optional) is installed in the same room as the heat source, approximately 1.7m above the floor. As the thermostat can be adjusted to suit the room and the occupants, positioning is not too critical. It is usual to place the switch or thermostat above an existing switch, so as to use the wiring pathway inside the wall.
This thermostat is set at a temperature level that allows the heated room to warm up before any heat is extracted. Once up to temperature the thermostat switches on and transfers excess heat to the cold areas of the house.
To make better use of larger heat transfer systems (eg for 3 to 4 room systems) and to slow heat loss from the heat source room, a speed controller (purchased separately) may be fitted to the fan. This can be set at a low speed when the area with the fire is occupied. Upon leaving the area (eg going to bed) turn the fan speed up to gain immediate advantage of the unused heat generated by the heat source. The thermostat will turn the fan off once the heat source room cools down.
Detailed installation instructions are provided with the heat transfer kit.
Can I use a Heat Transfer Unit with a Heat Pump?
This is not recommended because:
- It makes the Heat Pump work too hard. This is because Heat Pumps are sized to heat the room they are installed in. They work by pushing air into the room and circulating the air back through themselves, increasing the air temperature each time it goes through the pump until the desired temperature is reached in the room.
- By fitting a heat transfer unit, the Heat Pump is always heating new air and the heat pump room never gets up to temperature.
- By running the Heat Pump continuously at full output the power bill increases.
- This high running of the Heat Pump also shortens its life.
- Rooms heated with a Heat Pump have a more even air temperature distribution. Less hot air gathers at ceiling level, so transferred air is at a lower temperature than from a log burner and therefore less effective in heating the secondary area.
