Solar Storage Tanks – 80 Gallon Solar Hot Water Storage Tank

The electric element assists the system only when the solar energy cannot maintain the desired temperature or during periods of peak demand. Automatic temperature control thermostat keeps stored water at desired temperature. Our 80 gallon unit has two internal heat exchangers for systems that use heat transfer fluids.

Brass drain valve

  • Threaded stud located near the outlet for attachment of tank sensors
  • Temperature and pressure relief valve included
  • Collector feed and return fittings located at front of tank for convenient installation
  • 2.5″ thick polyurethane foam insulation reduces heat loss
  • Cold water inlet brings cold water to tank bottom to prevent mixing with heated water
  • Tanks can be horizontally mounted

A typical family of four in the U.S. uses about 80 gallons of hot water each day. To heat that water with electricity takes about 16 pounds of coal. In sunny Colorado, a standard solar hot water system can supply 60% – 95% of this energy, pollution free from the sun, while saving its owners about $250 per year.

Solar heated water may be stored in a tank that also houses an electric backup heating element (a “one-tank” system), or in a separate tank that feeds into the tank of a conventional gas or electric water heater (a “two-tank” system). The tanks are approximately the same size as modern hot water tanks, around 80 gallons or 300 liters. Solar energy preheats the household water.
