For those few days when the sun isn't quite strong enough, your Solahart is equipped with an electric booster. However, for even greater economy you have the option of a natural gas booster. It's called the Natural Wonder. Without a doubt, the Solahart L Series is the finest direct heating solar hot water system available. The L Series effectively heats your water via solar collection panels which are exposed to the sun.
Cold water is introduced into the solar collector panels.
Radiation from the sun is then absorbed by the collectors and in turn by the water. This means that hot water rises up through the solar collector and feeds into the system's fully insulated storage tank. More cooler water circulates back into the collector panels and the cycle starts again. No pumps or moving parts are required which means less water and lower maintenance. To further ensure long life durability, the storage cylinder is double coated with ceramic lining.
