RE: [GBlist] Heat Sources

[JOHN SALMEN <terrain@shaw.ca>]

I think what John describes here the right approach. I'm doing something
similar to condition a basement area that has an envelope separation from
the main dwelling.

A couple of things to keep in mind
- every additional insulationg and weatherproofing that basement will be
represented in energy savings.
- if the basement contains laundry, freezer, hotwater tanks, lights and
energetic people it is effectively being heated to some degree, the question
to answer is what additional heat may be required.
- A home needs a ventilation plan and this typically means exhausting heat
to the outdoors or utilizing some form of heat recovery. The upperpoint of a
house 'may' be a good exhaust point (especially with wood heat) and the
ground floor entry (basement) 'may' be a good entry point for replacement or
make-up air. Blending the incoming air with a % of heated exhaust air is one
scenario or recovering the heat from the exhausted air and introducing it to
the incoming air at ground level is another approach. It is also possible to
recover that heat as hot water which may or may not work in with your
geothermal.

First make sure that you have a combustion air source to prevent drawing a
vacuum on your structure. This would greatly increase infiltration and a
chilling of the entire perimeter. You can also suck in RADON gas with its
lovely daughter CESIUM.

I would then put in a high efficiency blower to draw air from high inside
the upstairs and discharge it thru a duct down to the lower level.
Grainger has several variable speed inline blowers that are well worth the
money on efficiency and quiet. If you wish a variable speed triac switch
and perhaps a relay and Thermostat.

There are possbilities with a reversable blower for a/c destratify.

A pleat filter on the upper end will catch all those escapees from your
stove.

Just another snorkel..
