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 engineered to meet the international demand for a simple, durable and inexpensive domestic 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.
In addition to reducing your electrical or gas usage for water heating, you can receive up to a 40% solar tax credit which can help reduce the cost of your passive solar heating system. Reduce your energy bills and let Sun-Tech Services, Inc., install your CopperHeart system today!
If properly installed and maintained the CopperHeart ICS can safely be deployed in areas that experience occasional mild freeze conditons. SRCC Rated Freeze Tolerance: 20° F for 18 hours.
CopperHeart SRCC G300 System Ratings
The Solar Rating & Certification Corporation OG-300 systems level rating is an independent assessment of both system reliability and performance. Systems that receive this rating must meet HUD minimum property standards in addition to a rigorous review performed by SRCC staff and design review team. Once the system has passed these quality assurance checks it undergoes a full performance analysis to estimate the actual solar contribution of the system towards an average hot water load. This contribution, as defined by the Solar Energy Factor is listed alongside the different variants of each system type.

How it works


The all copper collector/storage tank absorbs solar radiation through its selective surface coating by raising the temperature of the water stored in the collector. It is well insulated with closed cell foam and double-glazed for increased heat retention.
The 4” diameter copper tubes are welded into a series flow pattern so that the top of the lower tube feeds the bottom of the next tube. This allows the collector to contain the colder replacement water in the lower tubes where is is heated by the sun as if flows from one tube to the next. Each time hot water is used, the innovative design eliminates the cooling down of the remaining heated water that normally occurs in other types of solar water heating systems.
Not only does this design ensure the delivery of the hottest water, but it also provides more hot water at a higher temperature and with a faster recovery time than solar systems of similar capacity.
