Schüco Solar Electric Backup Storage Tanks
Standard Solar Tank S WW 75-1 E / 115-1 E
Schüco Solar Electric Backup Storage Tank
The Schüco Solar 75 and 115 gallon electric backup water heaters are specially designed for optimum energy efficiency as well as ease of installation. These tanks have an immersed double wall 1½” O.D. enameled steel heat exchanger ensuring separation of potable water and the solar heat transfer fluid. In addition, these tanks can be easily connected to the solar station with a prefabricated mounting bracket and piping kit.
Other features
- Tanks are shipped with two pre-wired PT-1000 sensors (installed at top and bottom of tank) which permit a quick and easy connection to any of the Schüco differential controllers
- A cold water inlet sediment reducing dip tube helps prevent sediment build up and increases first hour delivery of hot water while minimizing temperature build up in tank
- Units ship with T&P valve as well as an ASSE 1017 approved thermostatic mixing valve
