Solar Water Heater

Well it has been interesting watching Carl trying to figure out what the best glass is for the solar water heater. Glass is not just glass as I have found out. There is low E, reflective properties, glass filled with weird chemicals...you name it. Black glass is not good, and I would have thought it perfect, heat is what we want, and black glass gets might hot, but alas the reflective property on the inside it not good...the wrong rays are reflected back...or not allowed in at all. It is enough to make ones head explode. Anyway the fact that we need a source of constant hot water for our use and to heat the floor is kind o' necessary. We want to go off the grid and the heater has to be function perfectly...showers and laundry as well as a warm floor are not options!!! This is going to be our summer holiday...making a solar water heater. So, all you campers out there enjoy the summer and may a tree not fall on your tent, or may you not be swallowed up by a raging creek after a freak thunder storm, but enjoy nature in peace, joy and love. Man that sounds like a hippie thing to say! Kumb-by-ya, ya'll!!
