This Site Might Help You. RE: pros and cons of active solar heating? plz help
I'm using active solar to heat my house. I have 4 solar water heater collectors heating 120 gallons of water. That water is pumped through a wall mounted fan coil heater, but it could alternatively be used to heat a radiant floor or for forced hot air with a water to air heat exchanger. The pros are that I use less fossil fuel to heat my house, the sun provides free heat, and I just need a little bit of electricity to power the pumps and fan. My electric bill has dropped significantly. The con is that when we have a long stretch of bad weather, I don't get free heat, my backup electric heater has to come on. But at least it comes on much much less than it used to. It also doesn't get hot enough to use with a radiator heater that needs 180 degrees F. With solar, I can make about 130 degrees max in the winter, so low temperature heating systems are required (as mentioned above).
