What are we up to? So we want comfort? Do we want something to do online? Do we want to save the planet? Do we want to have the utility companies to pay us. to live/heat/cool? We know this type of system works if properly designed and installed. Why are we here doing this? Why are you here? This is why I am here: I like it. It is fun for me. What a hoot I get to making my hobby into my livelyhood.
