How Does Passive Air Heating System Work And Is It Reliable? Revisited For A Subzero 12 year report

An information session on a Solar Air Heating product that provides passive solar heating to a 1200 square foot shop building.
Solar Air Heating that requires no electricity from the building but rather operates using a small solar electric panel that runs the fan.
The unit is self-powered. It has a built-in
fan which is powered by an electricity producing Photo Voltaic (PV) panel.
The SolarSheat 1500 connects to a digital temperature control (DC thermostat), which enables the user to set a maximum room temperature.
The SolarSheat 1500 is designed so that it will not allow the internal fan to come on if the air is below roughly 68 degF
(20 degC) inside the collector.

An interesting concept. But it has the same shortcomings as any solar solution... It only works well when there's sunshine. To me, a geothermal solution would be the best. It utilizes the earth's own temperature. Or, if you happen to have access hot springs, you're even better off.

IDK...The sun has been pretty reliable for a long time. :) Seriously though...we have geothermal up at the house and it has been a good system but expensive to install/replace. If I were to revamp the system...I would leave the Solar system alone but would go with an air/air heat pump (mini-split) for the main heating system.

@@Springtailsolutions Would you say the solar solution provided primary or supplemental heat?

Since we are hardly in the shop at this time of year, I would call it "primary" (Since it is the one that runs the most)....as I mentioned in the video, the goal was to keep the temp in the shop above freezing. Which according to the thermometer, the temp has not dropped below 35 degrees (even with a week of -5 to -15 degrees. Those are unusual temps and only occur about 3 weeks out of the year. It is not unusual to have shop temps in the mid/upper-40s for the rest of the winter. I think if the size of the solar system was tripled....one could expect temps in the 50s. In the spring and fall, it definitely evens out the temperatures and we hardly ever use the ceiling heaters. Best part is that after the initial investment....there has been zero cost other than replacing the thermostat once in 12 years.
