Great video explaining residential solar heating! My 6x6 unit I built produces 95C of heated air when sunny. I plug the insulated plugs in the morning and click on the duct fan and replace the plugs at supper time trapping the heat inside the house. Best results if house is highly insulated.
I was building and testing these with a engineer years ago that made a national magazine cover. They do work great. Although if they are being built in a south facing window that already exist you don't gain a thing except u.v. protection. So any unit should be installed in addition to current window, the empty wall space or ground mount is best option.
I assume these are really only for desert environments where its really sunny and hot in the day but really cold at night. Winter days where I live are almost always cloudy but summer nights are still hot.
A solar furnace is just a thermal solar collector that uses air as the working fluid. A typical Photovoltaic panel is 200-250 Watts of electricity, same footprint can collect 1000-1400 watts in pure heat(about the same as a small electric water heater). Cloudy days = reduced capacity. There is a company in Canada that uses the solar collector vacuum heat pipes and an insulated central tank(thermal battery) in the basement to do water+whole house heating, only moving part is the circulation pump, and that only draws about 20-40 watts.
You'd be surprised. Even in winter, you can get a surprising amount of heat from it. The best part is that you can use it for convection cooling in summer, if you add an exit valve for that purpose.
you get free heat when the sun is out, in winter.(its cold in winter, usually).... just plug the vents in the summer... and at night if your house cools down, then you need another form of heat because the sun isn't out.........
So folks, here in New Mexico it is very cold and windy in the DAY during the winter but usually lots of sun. So these units are extremely cost effective in the south west. Last week it was about 30 out with 25 MPH wind gusts and very sunny. Red feather is trying to bring heating to extremely poor Native Americans who are living without utilities including water. It is often left to older woman to spend all day collecting fire wood. So for all of us privileged people who have access to electricity, natural gas and running water this is probably not a solution for you if you live where its cloudy. Please don't be upset about regionals specific solutions to improve peoples lives because it is very helpful in the right place.
We really love seeing our heater in this video - red feather continues to impress!
Do you manufacturer these im interested in the purchasing several of these

Hey Tommy, could PV's be used as the heat collectors? If so, you could have duel use systems.
@@frankmeyers7304 yes could certainly make pv + air heating panels for specific projects…
Great however in the UK when you need to heat your home its winter cloudy and not a lot of daylight so I'm guessing no use to uk
Great , now where do you buy this and how much is it Red Feather?
Did u ever try solar heating 🤔 during the day.
Awesome 👏
Thank you. This is great 🌅
looks cool. Is it still better than heating from PV (PV works a bit when cloudy)?
Our heaters will continue to put out some heat even when cloudy, thanks to the UV coming through the cloud layer and into the heater.

💘 love THIS...
You get free heat during the day...when it already hot outside. then you need a separate heating unit for night. What did I miss here?

Very true! @@erickanorris567
Is it enough to get through the night???
We have customers who use our heaters in conjunction with well insulated living spaces and most get through the night with solar air heating alone.
What do you do with it during the summer
Cook!
Use it as a mirror
Turn it on and sweat .
Most of our customers cover them up during the summer
We have been looking
We live in Dennehotso Az will be contacting you
Sounds good!
You should shorten your into significantly 😅
Too much childish ----
What is the purpose of the long winded introduction? So long I lost interest.
