At present Carrier has designed the kit to fit a three room maximum. A two room splitter may be added to a three room kit, with extra ducting and outlet grille to move air to another room. This will not provide as efficient a system as the three room kit, however it can and has been done successfully.
Carrier recommend adhering to the specified kit measurements for best results, however we recognise that many houses are designed differently. There have been a number of installations involving moving heat up to 18m away from the heat source and working almost as efficiently. Adding extra ducting means the hot air has to move further, hence a small heat loss. Any further than 18m is strongly discouraged.
Although the Heat Transfer Kit is designed to move heat, there will be a temperature drop in the process. It should be remembered that you require your rooms to be comfortable, hence the Heat Transfer Kit is designed to warm the rooms rather than make them hot.
It is possible to duct up and down. Depending on the application, moving heat up occurs naturally and with the help of the in-line duct fan the hot air will move downwards just as effectively.
Because the fan is installed in the ceiling roof space, the noise level is cut down significantly to a constant hum which can be heard. Carrier have installed over 1000 kits without any noise complaints.
Carrier has put together a well balanced system. If a more powerful fan is used, there is the possibility of more noise and gales of air. A smaller fan results in a limited volume of hot air passed through.
Yes, you can purchase an accessory thermostat. The thermostat is installed in your living room/lounge area. Once set at the required temperature, and the ceiling space reaches this temperature, the Heat Transfer Kit automatically switches on. A thermostat is a good idea to prevent the Heat Kit being turned on too early before you living room is well heated.
A speed controller is designed to reduce the airflow, especially when the kit is used as a ventilation system (explained later). It has been noted that when the kit is used as a ventilation system the air movement is more noticeable and a speed controller is useful to reduce these drafts.
All the kits come standard with easy, fully adjustable outlet grilles that can reduce or even shut off air to one or more rooms.
Just as the kit is designed to transfer heat during winter, it can also be used to transfer cool air during summer. Simply by opening windows in the living area a fresh air source is provided and once moving, the fresh air feels cool. By opening windows in the bedrooms there is a continual cycle of air keeping the house cool.
The Heat Transfer Kit is not a dehumidifier, however it does reduce the risk of dampness because it provides a constant air movement, therefore preventing moisture settling on cool surfaces.
The 1, 2 and 3 room kits will all use the same power (or less) as a 100w light bulb.
The in-line duct fan comes with a 12 month warranty.
Degrees Ahead have suppliers that have designed a well balanced system that has undergone extensive trials before being introduced to the market. The fan motors are powerful and reliable and all ducting is insulated to reduce heat loss. Some other kits provide under-powered fans and uninsulated ducting, obviously to save on costs at the expense of providing a superior product.
