Solar Heater or Solar Furnace for home heating
This video shows some details of the results of my home made solar home heater I built from ideas i got from the web and other youtubers. …

gehngus , you can use a thermostat in the house and control the switch of the fan with it. With the thermostat you control a relais, which on its turn switches the fan on and/or off. You can also use a thermostat in the solar funnel, use it in combination with the thermostat in the house. So when it is too hot in the house, or the air too cold in the funnel, the fan will not blow air into the house.
Very Nice!
does the fan come on only if it is hot? or is it manual?
I have seen some one use a solar cell panel to power a fan so it only works if there is enough light.
Also, how do you turn it off in the summer when its roasting inside and out?
many thanks
i would be curious to hear how your solar furnace performed through the winter?
great video ~ would like to see another!
The structure of the pipe itself provoques some turbulence as it is not a smooth surface. Painting the tubes black could increase the efficiency too.
Thank you for sharing; the idea of recycling air from inside is great.
What do you think about the following: I would change exhaust and inlet from position. Hot air rises; having the hot air coming in from below enables the natural heating process from low to high. I am impressed with the results of your design. Thank you for sharing : - )
Yours works and looks great, congrats on good job.
There is nothing in the pipes. That was not something i thought of.
Did you put anything inside the pipes to create airflow turbulence to improve heat transfer between pipes and the flow of air.
Just an update.
It has been around -20 celcius for about 3 days now with clear blue skies.
I am getting about 44 Celcius inside the heater and the house gets up to about 22 celcius over the day.
I have a couple ideas to try for the fan etc.
i will post updates as i get them.
Very nice project!
Was the outer part of the frame the only part that warped? Warping is something that I am trying to prevent…. I just saw a note below that you switched to aluminum flashing. I’ll have to use that.
I’m planning something similar for next year. I think I’ll use smaller air vents to prevent heat loss at night. Do you have insulation plugs for those holes?
Also, this is a passive solar heater. A solar furnace involves concentration of light by reflection or refraction.
You are correct.
The 3″ aluminum tube is it.
I used bbq paint on it.
I am in the process of building one myself.
What exactly is them material that you use instead of the tin cans. I saw some aluminum expandable tubing at home depot . expands out to 8 feet and cost about 9 bucks ….3 inch diameter …is that the stuff..they had some other stuff but it seem like it was covered in a very thing plastic
Nice panel!How did you fasten lexan on to panel?does being flat,make lexan move in the wind?I made mine curved,but it made it harder to build.might make next one flat.thnx in advance;
My lexan did not warp. The warped plastic is the black crap i had to use to cover the headers. I have since changed it out for aluminum flashing. Works much better. Thanks for the comment.
nice to see a variation from the can concept, my perspex warped to, I used 4mm, will upgrade to 6mm & give that a try.. enjoy the heat..
No matter the heating method, I have to believe, there will be stratification. Personally I find counter flow the most comfortable, again no matter the heating method. To me an a central heating system with the outlets in the ceiling. Anyway you are doing something, and experimenting. Thanks for sharing the results
I first used the fan sucking in at the floor and blowing up to the ceiling. A guy recommended that way to “destratisfy” the room. I have since swapped it to suck from the ceiling and push it to the floor. Both work about the same overall but i can feel the heat go across the floor passed my couch using the counter flow method.
Thanks, I got the meter at wallmart. I hate wallmart but I was there and saw it. It does both celcius and fahrenheit. I used the outside probe to detect inside the unit. It went up to 67 degrees Celcius then the next reading said HI. I guess it is out of range at that point.
Nice job…
I would like to find a thermometer like that to check my numbers.
Your house has great southern exposure too. That should help keep those utility bills down.
Nice work…
Counter flow as in forcing the heated air to travel in direction it doesn’t want to go naturally. Using a fan to force the heated air to exit out the bottom vent. That way the heated air warms at the floor level first before it rises to the ceiling.
I am using a fan.
Without a fan it get too hot inside the unit.
I must admit i do not understand what a counter flow configuration is…
Sounds like it has a fan. In the event you are using a fan, is there a reason why you didn’t use it in a counter flow configuration?
The tubes are 3″ aluminum dryer vent.
Keep it simple.
Where are you located?
I want to build one. Did you use plastic tubes? Any tips? Is there pretty good constant heat flow?
