Ducted Solar
Heating System
|
Solectair is a new way of
transferring stored heat from
your roof space into your home living areas.
Direct sunshine
on your roof's surface causes it to heat up.
This heat is
transferred into the roof space, creating a large readily available
heat source.
This warm air is then drawn from
the roof space and transferred
via ducting and
ceiling vents to each room in your home, thereby raising living room
temperatures at minimum cost.

Free Heat from the Sun - save
Hundreds of dollars on Home Heating!
"The use of Solectair will almost totally alleviate the need to
use conventional heating
During Autumn and Spring,
with a reduced need for conventional heating during Winter."

costs of the Solectair system are extremely low when compared to other
forms of heating, and for the test house with 7 outlets please refer to

House Suitability:
suitable (please check with your dealer) however, for good performance
the preferred home
1.
Any
roof cladding other than white tiles. (darker colours work better)
2.
A
large part of the roof exposed to the sun (minimal shading – e.g.
trees)
3.
Good
quality insulation on the ceiling and no insulation/membrane directly
under the roof cladding.
4.
A
level ceiling with an unventilated ceiling void for most of the home.
5.
Some
brick/masonry construction as this increases thermal mass to store
solar heat.
How
to Maximise Heating Performance:
1.
Because
Solectair utilises the available daytime solar energy, it is preferable
to transfer as much of this free heat into the thermal mass of the
house as is comfortably possible. This is achieved
by setting the controller to its maximum setting.
Due to the higher levels of solar heat often
available up to around the middle of autumn and after mid spring, the
maximum setting may need to be reduced so as not to become too hot in
the house, if occupied during the day. Some daytime discomfort can be
offset by warmer night time temperatures.
2.
To
allow the warm air entering the house to be increased further in
temperature (by passing back into the roof space via the ceiling return
air vent for reheating) and prevent entry of cooler outside air, keep
external doors and windows closed during the day.
3.
To
warm rooms not fitted with outlet vents, e.g. bathrooms & laundry,
leave their internal doors open during the day.
4.
To
prevent heat loss after sundown, close curtains & blinds, also
bathroom & laundry doors.
