Hot Water
We mean “free” literally. Yes, you’ll spend money up front to install the heating system, but your home equity will increase instantly, often enough to offset the cost of installation. You’ll also pay reduced utility bills — saving more money every time rates rise. Within a few years, you’ll recover the initial expense. Experts agree, a solar water heater is far and away the easiest initial investment in renewable energy. Perhaps best of all, you’ll enjoy hot baths or showers with the satisfaction of knowing the energy comes directly from the sun.
Many people have the false belief that Solar Energy cannot work in the Northeast – states like New York, New Jersey, Connecticut, Massachusetts, and others, because the winters are too cold, too long, days are too short and it is too cloudy there too often.The truth is, Solar Thermal, or Solar Hot Water, is incredibly efficient and cost-effective in the Northeast. This is because of a newer technology – Evacuated Tube Solar Collectors. Evacuated-tube collectors involve literally a visible set of parallel glass tubes (solar tubes). “Evacuated”, in this case, means a “vacuum” layer within the tubes, where it is also located heat pipes to absorb solar energy and to transfer it to a liquid medium. The vacuum allows very small heat losses and eliminates the impact of ambient temperatures, making evacuated-tube technology particularly suitable for colder climates.

Inside the glass tube is the copper heat pipe. It is a sealed hollow copper tube that contains a small amount of proprietary liquid, which under low pressure boils at a very low temperature. In fact the liquid contained in the heat pipe boils at only 86 °F (30 °C).This heat pipe rapidly and efficiently transfers the captured thermal energy through the evacuated tube and delivers it to the manifold (header) as the liquid boils and rises. As the heat is removed from the heat pipe by the copper header, the liquid condenses and gravity returns it to the base of the heat pipe so that the process is continually repeated.

Flat Panel Collectors
An alternative to evacuated tubes is the flat panel collector. It is an insulated weatherproof enclosure with an absorber plate, flow tubes, and a transparent cover. The transparent cover allows solar energy to pass through and be absorbed by the flow tubes. The heat generated is then transferred to the fluid circulating through the flow tubes. An indirect system pumps heat-transfer fluids (usually a non-toxic propylene glycol-water antifreeze mixture) through collectors, and then transfers the heated fluid from the collectors to a storage tank. Heat exchangers transfer the heat from the fluid to the household water stored in the tank.
