transfer HEAT
Airflow Heat Transfer Systems allows full use to be made of the many
effective and economical heating systems, now available on the
market. The hotter the air that leaves a heating appliance, the lighter
it is, so hot air quickly rises and hovers where it does little good. Airflow
Heat Transfer is the answer to a lot of household heating problems, by
taking the chill off cold bedrooms and creating an airflow and warmth that in turn, reduce
the likelihood of condensation and dampness.
There are several ways air transfer kits can be used. Some situations can be straight forward
while other situations may require further products to ensure that the right outcome is
achieved for the individual customer’s requirements.
That is why we at Airflow – The HVAC Shop have a wide range of products available to
custom tailor your individual system to your personal needs and satisfaction.
Ducting fitted with a fan can be used to transfer warm air
from a heated room to unheated parts of a house. This
system is termed a “heat transfer system”
Heat transfer systems are most effective at providing back-
up heating for rooms not normally requiring constant
heating, such as bedrooms.
By connecting a heated living area with a
bedroom, a heat transfer system enables
residual heat from the heated room to be
passed to the bedroom. A heat transfer system
can also be used to improve the warm air
circulation throughout a home.
Heat transfer systems can be installed in several ways.
They are useful in transferring heat from one end of the
house to another and from one room to an adjacent
room. Where warm air from a downstairs heat collects
upstairs, a heat transfer can be used to help bring the
warm air back downstairs.
Choose from our standard kits, and accessories, or have
a kit designed around your specific needs.
Although a 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.

transfer HEAT
"Heat", in a domestic dwelling context, usually means warmed air. Unless air has a
compelling reason to circulate throughout your home, then you will typically have rooms
or areas within your house which are quite warm and other areas which are quite cool.
Effectively, air transfer systems create a slow circulation of warm, dry air around the house,
displacing moist, cool, stale air with warm dry air from the ducting.
Heat Transfer systems work very well with wood heaters and non-ducted "Heat Pumps"
(reverse-cycle air conditioners). Typically, these systems effectively only heat "pockets" of
the house, so air transfer systems help to more equally distribute the air, particularly to
bedrooms, to more uniformly spread the heat.
As air is removed from the heated room, replacement air is drawn from adjacent rooms, creating
a natural re-circulation; hence warm, dry air is constantly being circulated throughout the home.
You can control which rooms you want the heat transferred to. The round
outlet diffusers can be fully adjusted in each room. If you require more
heated air entering one room than another, then simply adjust the diffusers
to your requirements. You can also completely shut off a diffuser if you do
not wish to deliver the heated air to a particular room (perfect for guest
bedroom).
Airflow Transfer Systems use high quality components our fans are the absolute best quality.
Airflow has over 27 years’ experience in providing ventilation solutions and will always select
the best fan for the application. Each kit incorporates a different fan which is designed to
provide the correct air flow and pressure requirements for the situation.
With our Airflow products, as with our other products, price is not the most important
principle in deciding what we can sell to our customers. You might sometimes be able to
buy cheaper products elsewhere, but we guarantee the quality of our products - we
purchase from premium manufacturers. We believe that in this industry, quality and
reliability really matter.

frequent QUESTIONS
1. How many rooms can heat be transferred to?
Airflow – The HVAC Shop has designed our Heat Transfer Systems to transfer heat to four rooms,
although we size our fans and ducting to use your requirements, five rooms would be about the limit
of efficiency.
2. Can extra ducting be added to transfer system?
We recommend that extra ducting is not added to a specified kit inventory, as these systems have
fans to suit the measurement of ducting included in the systems. For best results, we would prefer to
design and offer a fan to suit your requirements.
3. Does the system heat up the bedroom to the same temperature in the living room?
Although Airflow Transfer Systems are designed to move heat, there will be a temperature drop in
the process. It should be remembered these systems are most effective at providing background
warmth for rooms not normally requiring constant heating, such as bedrooms.
4. Is it possible to duct to an upstairs area?
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.
5. How much power do the Airflow Heat Transfer Systems use?
Power consumption for the one room kit is a low 40W; this is equivalent to half the power
consumption of an average sized light bulb. The one-room system uses up to 40W, the three room
system up to 54W and the four room 128W.
6. Where should the fan be located?
The fan may be in any section of the ducting, but before any ‘Y’ branches. Try to locate the fan as
far away from quiet spaces as practical.
7. How does the thermostat work?
The thermostat is installed in the heat source room. Set the required temperature you wish the fan
to turn on to transfer the heat when the air at ceiling level reaches this temperature the Heat Transfer
System will automatically switch on.
8. Is it possible to close off heat to one or more rooms?
All the kits come with fully adjustable outlet grilles that can reduce or even shut off air to one or
more rooms.
9. Is it necessary to suspend the fan?
Since all fans make slight vibrations while running, it is advised that you not mount the fan on an
inflexible wooden or metal structure. As an alternative, try hanging the fan from straps or bungee
cords or laying it atop or cradling a rubber or felt mat. It is recommended that a registered
electrician wire the fan.
10. There are cheaper Heat Transfer Systems available, why is this?
Airflow – The HVAC Shop design systems that suit the system resistance, the fans are powerful and
reliable; ducting is insulated to reduce heat loss. Airflow – The HVAC Shop will design a system for
your needs, not just supply an off the shelf unit.

our FANS
The reason our Airflow Transfer Systems Are Unique are because we select the fans in the
system to suit the amount of duct. These heat transfer systems 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 2-4 air changes per hour in each destination
room, assuming approximately 20-25m³ per room. The heat source and a heat transfer kit
will work quite well in most situations but remember it is only heat transfer, it is very unlikely
to be as effective as a central heating system.

NOISE RATINGS
Sound is measured in decibels; most fan brochures include a noise level (say xx dB). If you
are comparing different brands or models, the distance from the fan that the reading is
taken makes a big difference. A reading taken at 1 metre is going to be louder than one
at 3 metres. Carpet on the floor and curtains help to reduce some of the reflections off the
walls, and hence it appears quieter than a hard room.
The fan should be no closer than 2 duct diameters from the end grille, in order to give the
airflow a chance to straighten out and reduce turbulence losses. Fan noise is largely
dependent on the air velocity through the grilles, so most solutions involve reducing the air
speed, and larger ducting and grilles, or multiple inlets usually do this. Generally, the noise
is also proportional to the amount of airflow and the fan speed
OUTLET GRILLES
Round Downjet Diffusers are constructed from A.B.S polymers providing long term strength
and rigidity. The diffusers consist of a series of concentric rings that deliver the air downwards
at a slight angle to the vertical. The external exposed surfaces have an etched finish. A
centre knob can be pushed and turned by hand to adjust an integrated butterfly flap. The
flap impedes the airflow allowing individual control of airflow for an area. Total shut-off is
possible
DUCT INSTALLATION
Airflows through your duct work much like water flows through a garden hose. As long as
there are no kinks in the hose, you get a good volume of water flowing out of the end of
the hose. When you kink the end of the hose (for example by bending it near the nozzle)
suddenly you have much greater pressure. The water may seem to squirt farther, but the
reality is much less water is delivered. Always opt for the minimum length of flexible duct.
Any necessary bends should be made with not less than one duct diameter centerline
radius. When you do bend the duct, be careful not to compress it. Support flex duct
horizontally at intervals of not more than 1.5m. Support straps or other support material
should be at least 75mm wide.
ADDING EXTRA DUCTING
We do recommend adhering to the supplied ducting within the kit for best results; however,
we recognise that many houses are designed differently. There have been a number of
installations moving heat up to 21m away from the heat source and working as
efficiently. Adding extra duct means the hot air has to move further, hence a small heat
loss. Any further than 21m is strongly discouraged.
All our kits can be extended with extra ducting.

Sharp bends can greatly reduce the airflow and should be
avoided, the use of an Adjustable Metal Bend is recommended,
and these bends are adjustable for attachment for flex or metal
ductwork. Their rigid properties will keep flexible duct from
collapsing.

galvanised sheet metal for ease of joining two pieces of flex
ducting together.
A Speed Controller may be installed to eliminate draft and adjust
system to your needs. Where a fan is making a lot of noise due to
excessive airflow, this can be reduced in a controlled manner, until
such point as the noise becomes minimal and the airflow still
adequate. It is best to size a correct fan for the application and
eliminate the need for a speed controller.

Before buying any equipment, inspect the roof space to ensure enough clearance exists
between roofing and the ceiling lining, especially at the point where the fan and discharge
grilles are to be installed.
Before commencing work make a note of where the grilles are to be mounted and the
best possible route for the ducting avoiding as many bends as possible. Obstructions to the
ducting route must be noted and enough ducting purchased to by-pass roof stays and
rafters.
The heat transfer kit is most effective when the primary heat sources are a wood burner,
gas fireplace or reverse cycle air-conditioner. This is an energy efficient way of transferring
the excess heat from these heat sources.
The fan may be in any section of the duct run. This has the advantage of reducing the fan
noise away from living areas.
We recommend placing the inlet grille on the opposite side of the room to the heat source.
This allows the room to warm first before transferring excess heat.
Control
You can control which rooms you want the heat transferred to. The round outlet diffusers
can be fully adjusted in each room. If you require more heated air entering one room than
another, then simply adjust the diffusers to your requirements.
You can also completely shut off a diffuser if you do not wish to deliver the heated air to a
room. The outlet grilles should be installed in the ceiling at the furthest point from the door
(to encourage complete air circulation).
Duct
Avoid installing flex duct where it will be subjected to direct sunlight, such as under turbine
vents. Sunlight can degrade the vapor barrier. Avoid bending flex duct across or around
framing members, pipes and other objects. Such bends can decrease the size of the duct
at the bend point, restricting airflow and increasing air friction.
Over time, the duct inner core can continue to collapse at the bend point further restricting
airflow. This is a common installation error. Use an adjustable metal bend.
Electrical
ANY ELECTRICAL WORK SHOULD ONLY BE CARRIED OUT BY A LICENSED ELECTRICIAN
Doing electrical work, yourself can be dangerous. People have been killed doing electrical
work unsafely.
By law, any electrical installation work must be done by a licensed electrician. They must
test the work and give you a uniquely numbered Certificate of Compliance Electrical Work
to show it has been tested and ensure it complies with the regulations.
