Solar Air Heating – Product and Installation Summary

Last fall, we wrote about our evaluation, purchase and installation of the CanSolair Solar Max 240 solar air heater.

Solar air heaters are products which use the direct sun light to generate heat for the home, cottage or any type of building.

As they generate heat, the only form of energy they consume is a minor amount of electricity to run the internal fan to take the cool air from inside the home, push it out to the solar air heater on the south facing wall or roof, cause it to  be heated within the solar air heater and then push it back now heated into the home.

And, some of these products use a small solar panel to run the internal fan.

We had many, many visitors to our site,, throughout the publishing of this series of articles last fall.

So, we thought we would provide on one page all of the links to all of the articles. Since autumn is upon us, now is the time to be planning and ordering such units if you are hoping to have it installed before the snow comes.

And, if you have used a commercially available solar air heater, we would like to hear from your on  your experiences, so do drop us a line to

    Looks like a nice installation job. I am curious how well this heater is performing for you. I thought about buying one of these but due to the high price tag I opted to build one myself. This also allowed me to customize the size and integrated it into the design of my house. I finished the interior venting recently and it has been operating wonderfully. Now I just would like to figure out a way to measure it’s efficiency. For those interested, I have posted all of the details here:

      hi who made the unit in your picks? how many sq feet can it really heat? how much did the unit cost you?

      • Dan says:

        Hi Derrick,
        Our unit was made by CanSolair out of Nfld.

        I forget their actual estimates, but here is their URL where you can find more information about the unit:

        According to the web site “MSRP $2749.00 + shipping and taxes where applicable”

        I hope this helps,

    i have a cansolair on my house in charlottetown, pe, canada. last winter it saved me almost 1000 litres of heating oil.

  3. Dan says:

    Hi David,

    Wow, that’s terrific.

    I still don’t get Natural Resources Canada’s refusal to include suppor for Canadian products like these for residences in their ecoENERGY residential retrofit program.


  4. david lewis says:

    i suppose if it was made in new france it would have the federal governments support.

  5. derrick says:

    wow that sounds great whats the cost of instillation? also where is the best place to install roof or side wall?

  6. Dan says:

    Hi Derrick,
    There was only about $100 installation cost for the small parts, including the insulated flexible duct, etc.

    It is IMO easier to install on a wall, yet it will likely receive more direct sunlight on a south facing roof.

    Are you still happy with the heater? Interested in your thoughts now that its been a few years. Did cutting down the tree make a big difference? I’m in western Alaska at about 60.6 degrees north latitude and have been tempted to either buy or build one of these for years. For heating our home or even to put on the side of my little shipping container garage. Am interested to hear if you would still recommend it and how it is doing for you. thanks. -alaska pete

      It worked great the time we lived in that house, Alaska Pete. We have now moved from that house but I have not heard anything bad about the unit.
