i want to use abs elbows and horizontal runs 36″ long , the runs i was thinking of using heat capture recover units , they use copper tubes about 3″ wide and then wrap 3/4″ tubing a round that for water to flow through . i would fill this with glycal (plumbers antifreez ) . i live in eastern canada . burr.
painted flat black , the copper should heat the fluid and by way of a siphing cold in hot out at the top .and using a thermostore exchange could preheat all most all my water needs .
but the inner core that the air can flow through needs to be slowed , by way of disterbance finns of some kind made of again copper not to react with the tube , and also conduct the heat better . i am think not a spiral but something more random is need for those finns . more like a propeller shape on a boat prop.
any way . this i want to hanh on a wall not the roof because of snow .
and it will be in a box insulated at the back and sides ,top and bottom with 1″ pollysteren and foil cover to reflect light energy
also because of the space between tub will be about 4″ and the same deep . i want to make a ^ shaped piece out of allumium flashing and cover it with allumium foil to reflect even more light energy to the tubes .
and this box will have a thermal pane of glass over it . the one i am starting with will be 5′ high x 7′ wide .
the only thing i need now is to power the fan for the air tubes 50 cfm i think . i want to power that from a photovallic solar panel .
no need to use grid for a solar panel , to power a fan .
i would like any advice good or bad , i will build it my self , and the cost is just the materials . i have three thermal panels thats the cheap part .
if the heat recovery tubes are to exspencive i mite try pex over abs or maybe inside abs pipe ?
i need a littel help with the math , how mant btus of water heat and the how do i measure the btus that the air provides .
thanks for reading my rambels . kier.

A study in Newfoundland showed a 40% decrease in fuel usage. That is pretty cool. Active solar heating can very cost effective and I’m surprised I don’t see more of it.

We installed in on the south wall of our walkout basement and it was easier than originally anticipated, even for a non-experienced person like myself. We have measured temperature gain (or 'rise') of between 60 and 70 degrees F from the unit, with a maximum temperature reading of between 130 and 140 degrees coming out of the heating vent connected with an insulated flexible duct 24 feet away which was more than what I had thought. Folks can read about our evaluation and installation experiences, with pictures, here if interested to find out more. http://dailyhomerenotips.com/2008/10/24/solar-air-space-heating-part-1-another-type-of-solar-energy/ It would be great if there were more government subsidies for the home owner for these devices which consume zero home heating oil or natural gas when generating heat. The one we purchased simply plugs into an existing electrical outlet. Dan We installed a solar air heater this November and it is working quite well.
