Passive Solar Air Heater Heating System Alternative Energy

This is a video of the Passive Solar Heating System in use at www.envirosponsible.com in Whitby, Ontario, Canada. It provides a great deal of heat, and the installer, Chris, will be making it more effecient by adding a second computer fan to push the warm air at the top, painting the inside better and taping the duct work. Also, the duct work will be directed into the office where the door can be closed and used in a smaller air mass. This kind of heater is ideal for urban survival and bugging in, since it requires no power input and is cheap and easy to make. It’s not just for strawbale, cob, cabins, cottages, earth ships or businesses. They can be installed on a home, and they look great when done right. Ragnar Benson would be proud.

    thanks for info I have been thinking about making one for my roof using antifreeze and two radiators and a pump ran by solar cells

    Nice, I’m a thermodynamics guy too. I would say run your duct as short and straight as possible, or the PC fan will be useless. In fact you may be seeing convection right now, not fan forced. If you use a fan force the air to the floor so you can sense the benefit. Supplying to the ceiling only works well when removing heat (AC). Good luck.

    AMAZING AND AWESOME IDEA….THANKS FOR SHARING.

    @sircygnus Then that’d be “Solar Water Heating”, ne?

    @envirosponsible hi done one myself, on a similar baciss, but made to fit on the inside of my window. cannot put it outside/dam/ but with20 tin cans got 80 degrees out of the top pc ventilator, 20 dollar solar panell that kicks in at 40 degrees,= 20 dollars,and free tin cans, =80 degrees if I am correct fantastic rooaaarrr,lol regards chris keep it going bro.

    @zehboss FAIL :)

    @brotherkantutta You are the idiot… He is doing a good job. The panel is heating an interior room, without creating a cooling problem in the summer. It is people like you that keep people like him from sharing ideas with the world, therefore making it a better place. You run your mouth, and make the world a worse place. If you cant improve on peoples work, let them be, instead of givin’ them grief.

    I want to do it on my place.

    Chad, I like it. Not sure if you still have it installed but if you do, think about putting a one way baffle on the intakes. This way when the sun drops cold air doesn’t come back out through them. Remember the convection effect you are trying to take advantage of works both ways, the heat rising when the sun is up, the cold dropping when the sun is down, so you could in fact cancel all heat you captured during the day but cooling the building at night. It’s a cool project.

  10. Shinertheantizionist says:

    @ everyone who thinks the outlet belongs on the floor… Look at the heater outlet in any modern house, they are all on the wall near the ceiling. The intake should be near the floor and the outflow above so the cold air will be forced through the system. Also I forgot to mention below you need to have both the intake and outflow in the room being heated so the warmed air can recirculate through the system.

  11. Shinertheantizionist says:

    The fan should be sucking the air through the outlet instead of blowing in. You are losing over half the fans energy. Otherwise you did a great job, I like how you used an existing window.

  12. brotherkantutta says:

    Just let the sunshine come in you idiot.

  13. sircygnus says:

    @taruchansun; heat up a fluid such as water, and run it through baseboards. simple, effective, and is greatly more efficient.

  14. taruchansun says:

    @sircygnus so what would your suggestion be?
    how would they make it go below?

  15. sircygnus says:

    why would you pump heat from the ceiling down into the room? you need to pump the heat into the room from a vent in the floor as heat will rise. all you are doing is warming the ceiling.

  16. Thunderhook715 says:

    The color white reflects heat
    and black absorbs heat the absorbed heat is transferred to the air flow
    and moved to someplace with little to no heat  a passive heat pump

    @WasHighPingDuck having worked with concrete i can tell you it only has an R-value of one…no matter it’s thickness. Concrete is a terrible material to store heat or insulate from it.

  18. czarnianq says:

    @magicyte any municipality can have bi-laws on store front design. In Beamsville, ON a new pharmacy being built was having a legal fight with the town over a 40% windowed storefront law.

    i got a better idea lets go over to the oil guys and kick some ass take all the oil and heat the house with oil …oil for everyone in the usa

    REAL Free energy technology exists!But some very powerfull ppl don’t want you and me to be free from energy costs,Find a motor that needs no fuel or input at LT-MAGNET-MOTORdotCOM ,Be part of the revolution!

    Your site came up as an Attack Page on my anti-virus software; why???

  22. egn83b says:

    I think this idea is novel but it lacks common sense here’s why. Most rooms are cold at the bottom because cold falls and heat rises so why would you force warm air from above the room why not the bottom first to get the bitter chill out because as the bottom will warm so will the top as well. Plus the fan for that setup is way under powered but being free to use is awsome.

    @crazymonkeyVII The amount of energy that goes through the window is not a fuction of what is on the other side of the window. How that energy is managed is a function of what is on the inside of the window. Additional energy cannot be created. The energy can be concentrated, collected, moved, and repurposed but not created. Very little thermal energy is in the visible spectrum. IR spectrum is where most of the thermal energy is. You can reduce the energy lost out the window with insulation.

  24. crazymonkeyVII says:

    @zehboss not really true: a good solar air heater will concentrate the solar energy to make more heat. it converts the light to heat. if you just let it go through your window, the light will partly be used to lit up the objects in the room.
    on the downside, if you have that massive thing in front of you’re window, so you’ll have to light up the room with an light bolt…… therefor, it would indeed be more practical to place it on the roof or somewhere where it’s not blocking the window….

    @Umaxen Gain access?! The window has freaking bars blocking entry and exit.
