“… The vacuum between the tubes prevents heat loss during cold weather. Other solar heaters need antifreeze to keep working in winter. The Solar Quest system of tubes keeps working even at temperatures of minus 40 degrees F without any chemicals added to the purer water.

Another advantage of the new system is it integrates the function of hot water storage and solar energy collection into one unit. Evacuated tube collectors produce hotter water. The heated water keeps circulating through the tubes by a passive convection current. This eliminates the need and cost for a pump to circulate water between a storage tank and a heat collector. The storage tank is stainless steel with a polyurethane coating to insulate it from the outside weather. …”
