Bio Diesel Supply House 400 Liter Solar Water Heater Hot Water Tank Dual Coil & Electric Backup
The closed heating system uses anti-freeze as the working fluid inside. Once heated, this will circulate through the tank and heat the standing water. Because it is anti-freeze, it will be able to manage extreme temperatures year round. The tank itself is made from food grade stainless steel, with a galvanized steel exterior to withstand any pressure build up. Solar heating systems will often generate temperatures of 158 degrees. This can crack glass lined storage tanks, and once cracked, they will continue to deteriorate until permanent loss is formed. Designed more for commercial use, this 100-gallon solar-powered hot water heater will work great provided you have enough sun to keep it hot. If not, their electric backup generator will take care of the rest.
