Higher solar heating fractions???
I find it hard to believe that with today’s building and insulating technologies, that most or even all of a home’s space and hot water heating can not be provided by solar… I realize that the issues of heat storage and controlling the release of this heat need to be dealt with. I am intrigued by Robert Starr’s (www.radiantsolar.com) ideas for an insulated earth bed storage system. Read the DOE’s report on this system…they seem to be rather enthusiastic. (note that it was done in the 80’s). They really seem impressed with the systems ability to harvest and store heat at much lower temps, thereby significantly improving the efficiency. In his book “Solar Water Heating”, author Bob Ramlow briefly discusses the sand bed (high mass) storage system and he seems to think that it works well, although it does require some user input to control the system well. Any thoughts ???
