The CopperHeart integral collector storage system, or ICS, combines thermal collection and storage in a single unit.  The CopperHeart is engineered to meet the international demand for a simple, durable and inexpensive domestic solar water heating system. 

The retrofit CopperHeart installation typically serves as a solar preheater to the existing electric or gas water heater. 

For new construction, the backup heater of choice is most often a compatible tankless gas water heater.  In non-freeze climates, the CopperHeart may be used as the primary water heater.   For durability, reliability, and simplicity of installation and operation the CopperHeart ICS has no peers.

If properly installed and maintained the CopperHeart ICS can safely be deployed in areas that experience occasional mild freeze conditions.  ICC-SRCC Rated Freeze Tolerance:  20° F for 18 hours.
