Cold air convection system
Forced cold-air convection
heating system
Principles
To heat
a building with a radiant heat source and a high ceiling, convection is
all-important.
Cold, stale air sinks to the bottom of a
building like water sinks to the bottom of a container. To heat/freshen a room, it is much more
effective to drain/evacuate the sunken cold air from that room than to inject
desirable (hot/fresh) air. Draining
undesirable air pulls desirable air from adjacent rooms into the room being
drained.
Procedure
Start
with a radiant heat source like a wood stove
Connect
coldest area(s) of house to hottest with 2Ó plastic pipe
Install thermostatically-controlled fan(s) at the end(s) of the
pipe(s) in cold area(s)
Push
coldest air into hottest area(s).
Cold incoming air will mix with the hot air and make warm air.
Distance
ÒkÓ should be as great as possible while still creating mild turbulence in the
hottest area(s).
Requirements
Wood
stove or other radiant heat source.
Tight
envelope. Random cold (outside) air
entry points must be sealed for convection to be effective.
Advantages
Huge
savings in cost over forced hot air systems. 1/5 the cost of
installation, 1/3 the cost of operation.
Zone
control. Remote rooms can be left
alone, or each can have its own drain.
Can be
installed easily into existing buildings.
