All glass vacuum tube non pressure compact solar water heaters rely on the natural circulation of water between glass tubes and the tank. As water in the vacuum tubes is heated and rises naturally into the tank, while cold water in the tank flows down to the bottom of the vacuum tubes, causing circulation […]
1. Is solar water heating a viable alternative to gas or electricity?
Solar should not be seen as a alternative to gas or electricity, but rather a supplement. Solar cannot totally replace the need for gas or electric heating as there are sometimes days when there is little sunlight. When averaged over a year, a […]
