We're in the process of building a log home and are incorporating some
interesting Earth-friendly technology.
First of all, we're using a prodect called "Warmboard"
http://www.warmboard.com that is a special radiant heat subfloor. It
consists of 1 1/8" plywood with a 1/2" groove for the crosslinked
Polyethylene tubing. It has an aluminum coating to distribute the heat
evenly. This eliminates the use of concrete for the radiant heat and
is much more efficient than just stapling the pex under the floor.
We will use a high-efficiency propane hot water heater for the heat
source (Polaris) which has 94% Recovery Efficiency, Stainless Steel
Tank and Combustion Chamber/Flue, Sealed Combustion Vents (Intake and
Exhaust) with 2" PVC ABS or CPVC Schedule 40 Plastic Pipe, 2" Non-CFC
Polyurethane Foam to prevent heat loss & reduce energy costs,
Electronic Hot Surface Ignition and is tested and listed with CSA
International in accordance with the latest addition of ANSI Z21.10.3
• CSA 4.3, ASHRAE Standard 90. 1 b-1992 - thermal efficiency
requirements are met or exceeded.
The next step will be to add some solar collectors. The home has been
constructed to face due south, so the roof is a good location.
We're also installing a Manabloc water distribution system, which I'll
detail later.
