We enclosed our south facing front porch with five sets of glass sliding door units. On the coldest winter days that are sunny,the porch heats our entire home...
Here in Colorado they are talking about our ulitilies going up by 25 percent. I don't know about you but I can't afford to pay more to heat my home. I have Fibromyalsia and to get cold can knock me off my feet for days at a time. So my husband and I did a search on the internet for something that was cheap, could be made ourselves and could help out with the heating bills. Here we have a lot of days when we do have sunshine so we thought solar would be the way to go.
