"Fredericton man builds $300 solar furnace, decreases heating bill"

[FLson]

14. I use an integrated multi-source

system. It's very elaborate and I used a lot of surplus electronics and stuff. Set up a few different solar panels and couple small wind turbines to power it. Uses a heating coil system and a piped plumbing system (metal exterior, plastic interior) that cycles the heated water throughout the attic allowing passive heat buildup. The raccoons love it and it doesn't supply all the heat but it does reduce the power bill immensely in the winter, and it's also rigged up to a solar heating system for my pool.

The one time I tested it without using my A/C, it kept the house as warm as 64 degrees while it was 32 degrees outside. If I improved it to run pipes down the wall spaces with additional small heating units, I could probably get it far warmer. I use a sophisticated insulation, temperature control, and monitoring system.
