Home Solar Heating System, Version 1
This is a short video about my original solar home heating system. It was based upon a Harbor Freight solar greenhouse cooling fan to move solar heated air out of an enclosed patio into the house. The system worked well for a number of years and worked off of 100% solar energy, both for heat and for air handling.
I am re-using some of the components of the original system in my current heating system. I’ll describe that in a follow-up video. A keen observer might note that the fan is now mounted to exhaust air from the house rather than blow air inside. I’ll cover that in the version 2 video.
This system, installed in 2007, was my first introduction to solar power. The modest 30 watts of solar panel and small 12VDC fan performed quite well and would warm the house up on a sunny winter day.
Living in the SF Bay Area of California, winters are fairly mild, so this was enough heat most of the time. The main weakness of the system was on cold, windy days, when the enclosed patio space would not heat up much and that would kill any heat gain that day. The other downside was the air handling was limited with the single fan.
The system could warm my house up 5-7*F and a few good days I recall it raising the temperature 10*F, although that was likely in the late spring.
Here is a link to someone who installed the same HF cooling fan in their greenhouse, so you can get an idea of its intended application:
