I love to build and tinker when I can. Buying a house for 18K is for sure a tinkerer's paradise...
Anyway to keep the house warm (cause the place had ZERO insulation when we bought it) I built a small solar collector (about 2' X 4') and it would raise the temp of the air by about 40 degrees in full direct sunlight but the airflow was heavily restricted. When I upgraded I built a 4' X 8' version increased the input and output holes by about an inch and made larger channels for the air to flow through. The results are Amazing as the fan only uses about 100 watts of power or about 20 cents per day to run. Did I mention it can increase the air temp by about 80 degrees? Not bad for about 100 bucks worth of material.
It's been in use for two years now and while it got a few scuffs in the plexiglass it has held together pretty well for an experiment. The input and output are made using a toilet flange and a pair of them are also mounted to an insulated board that is put into the window and one is on the inside as well so the fan can blow the air in. You can see a small wire with a silver section in the upper right which is one of the temperature sensors that reads the output/in box temperature with another that is not visible in the input line that reads the temp from the air flowing from inside the house. Everything is piped into HomeAssistant and the fan goes on and off based on the temperature settings in Node RED using a Sonoff Basic. The override is a simple switch in HomeAssistant that I can use to keep the fan running even if it's a bit warmer in the house but will be cooler in the coming days.
On a sunny but cool day (around 40 F) it will raise 60 degree air near the floor to around 130 degrees and raise the temp of the entire house by about 10 degrees and that was with zero insulation in the roof/upstairs.
So anyone else like to do less computer related things DIY? I enjoy sharing and helping others with things like this so if I have done something that is interesting and you want more detailed plans or help let me know. I am probably going to write up something a little more in depth and post it on my site for anyone interested as long as the admins have no issue with the links. I would also enjoy seeing other's projects if they have them.
