Cirrex® Solar Electric Water Heater System

Cirrex® Solar Electric Water Heater System

Model SACI-02-M200202-000


Cirrex® from A. O. Smith is a leap forward in solar thermal water heating and quite simply one of the greenest solution available to homeowners today. Up to 70% of its energy comes from the sun, not from the power company, which can significantly reduce the homeowner’s utility bills in addition to helping protect the planet. Cirrex is an all-in-one system, which simplifies specification and installation for the contractor. Its solar thermal collectors can generate as much energy as traditional photovoltaic solar panels at one-eighth the cost. The 80- or 120-gallon Cirrex system comes with a one, two or three-panel configuration, which easily meets the needs of a plumbing contractor. In addition, the ENERGY STAR®-qualified Cirrex has Solar Energy Factors up to 10.1 and is eligible for a federal tax credit of 30% of the entire installation cost with no cap. Furthermore, local utility rebates are often available in addition to the federal tax credit.

The SACI-02-M200202-000 is an indirect solar booster water heater with a 120-gallon tank that is specially designed for installation as part of a direct solar water heating system. It provides an energy-efficient supplementary source of water heating power and hot water storage to help maintain consistent water temperature during periods when direct solar components cannot meet system demands.

How it Works

Cirrex® Solar Water Heater Systems utilize energy from the sun to provide hot water. System components include: solar thermal collectors mounted on a south facing roof, solar loop piping, an integrated solar pump station, a solar loop expansion tank, a solar booster tank and a heat exchanger.

The sun heats a transfer fluid flowing through the solar collectors. The heat transfer fluid is a mixture of distilled water and non-toxic propylene glycol to prevent freezing in the winter. The integrated pump station circulates the heat transfer fluid through the solar loop piping to a heat exchanger where the heat energy is transferred to the water inside a solar booster tank.
