 CopperHeart Integral Collector Storage (ICS)                                         


The CopperHeart integral collector storage system, or ICS, combines thermal collection and storage in a single unit.  The CopperHeart is designed to meet the international demand for a simple, durable and inexpensive domestic water heating system.  The CopperHeart typically serves as a solar preheater to an existing electric or gas water heater, but may be used as the primary water heater in certain climates. 

ICS units are excellent choices for residential new construction in the U.S. Sunbelt or other mild climates that do not experience hard freeze conditions. Check out the Eaton/Dole freeze protection valves below.

PLEASE NOTE: The CopperHeart heater will far outlast the Eaton/Dole valve, we recommend replacement every six years.

SOLAR BiZ Freeze Protection Valves                                          


Solar Biz Models FP-35 or FP-45

Freeze protection bleed valve utilizes a temperature activated element which does not require any external source of power. The valve opens at 38, or 43 1/2F ( depending on model number) allowing the discharge of near freezing water which is replaced by warmer water. When this warmer water reaches the valve, the port closes. This cycle repeats as often as necessary. The amount of water dispensed depends mainly on ambient air temperature, make up water temperature, the duration of the cold spell and the number and size of collectors. The system is functioning properly when water is being discharged from the valve during near freezing conditions. For water to be discharged at the time of operation, system water pressure must be maintained. High temperature plastic body, 1/2" male threaded connection. 5/8"ID anti-siphon discharge port, 150 PSI maximum operating pressure.
