EarthLinked^® is not just about heating and cooling your home. EarthLinked^® heat pump technology has also produced the most efficient water heater ever tested at the Florida Solar Energy Center.

Heating water from renewable energy for residential use can be accomplished in two different ways:  through integrated full-time water preheating or through "desuperheating" water heating.

Integrated Renewable Energy Water Heating

Desuperheating water heating reclaims heat from the A/C cycle to heat water. Its first cost is lower. Savings are realized in the cooling season by transferring waste heat to your hot water storage tank. Even in the heating mode the desuperheater often provides pre-heating to the water heater, reducing the work required of the electric resistance elements.

Increased Capacity and Reliability

Adding the EarthLinked^® system to the traditional water heater creates a hybrid system with increased system capacity and reliability.

EarthLinked^® heat pumps have been operating since 1983 and are located in 15 countries, including northern and southern extremes. The systems are engineered for mechanical simplicity and reliability. They transfer renewable energy from a heat source that has been stable for millions of years. Just set the desired water temperature on the traditional water heater tank and forget it. If the heat pump should ever require service, the traditional water heater storage tank serves as a back-up source which assures a constant supply of hot water at the set temperature.

Safe and Renewable Energy

Because there is no fossil fuel firing required by the EarthLinked^® system, there is no risk of fuel leaks, explosion, fumes or asphyxiation. Geothermal energy is a safe and renewable form of energy.

Unobtrusive Installation

The EarthLinked^® heat pump is located in a single cabinet that contains the high efficiency scroll compressor, the refrigerant-to-water heat exchanger and a small, quiet and dependable water circulating pump. The cabinet size is 17”x 21”x 28", which is the size of a two drawer file cabinet. It can be located adjacent to the traditional water heater tank.

Versatile Earth Loop Installation

Because of high efficiency thermal exchange with its heat source in the earth, only 100 feet of earth loop per ton of heat pump capacity is needed, and a three inch diameter bore hole is optimal. Therefore the system is easily adapted to retrofit applications and new construction. The earth loops can be installed vertically, diagonally, or horizontally by trenching, drilling, excavation or directional boring even under a parking lot.

Serviceability

The system is designed for dependability and ease of service. It includes industry-standard threaded water piping connections, pump unions, and refrigerant service valves. In addition to the refrigerant management controls, the key internal components include a high efficiency, brazed plate heat exchanger and a readily accessible bronze body water circulating pump.
