Australian Geothermal Heating - Commercial Renewable Energy Water Heating

Commercial Renewable Energy Water Heating

Geothermal Renewable Energy Commercial Water Heating reduces the cost of heating large quantities of water up to 75%. With a certified coefficiency of between 3.5 and over 5.0, it is the only system verified by U.S. EPA to achieve 400% electrical efficiency and it does so every hour of the year by delivering renewable energy.

Cost Benefits of Renewable Energy Water Heating

EarthLinked® delivers up to 400% electrical efficiency. For every Watt of electricity consumed by the EarthLinked® compressor, the system delivers three to four times that amount of heat energy to the water tank because it is primarily transporting renewable energy.

Even though the installed cost of the EarthLinked® heat pump system is greater than traditional water heaters, the monthly energy savings in commercial applications are so large that the system quickly pays for itself.

A commercial user with an EarthLinked® water heating system installed at a cost of $15,000, using 2,000 gallons of hot water per day, an electric rate of $0.1/kWh, a temperature to 115 ^oF and the electric resistance element raises it to 125 ^oF, in comparison with an electric water heater saves $6,681 annually.

The cost recovery period in that case is 2.2 years, for a Return On Investment of 45.4%. Even if the installation cost was $20,000, payback would be within 3 years and Return On Investment would be 33.9%.

Environmental Benefits

Burning fuels to create heat wastes diminishing natural resources and can never achieve 100% efficiency. The process pollutes the environment with carbon dioxide and nitrogen oxides that are greenhouse gases. The U.S. EPA and DOE have determined that, in most applications, geothermal heat pumps are the most energy efficient and environmentally friendly heating systems.

Constantly Available Renewable Energy Source

The constant renewable energy from the earth is always available and is not dependent upon sunlight hours or temperate climate. This creates the ability to use heat pumps to deliver heat in cold climates, shift demand off-peak and thereby use lower electric rates for water heating, including pools, radiant hydronic heating and thermal storage.

Benefits of EarthLinked® Over Electric Water Heating

Up to 75% energy savings due to reduced electricity consumption
Environmentally friendly renewable energy
Reduced electric demand and possible reduced demand charge
Decreased energy dependence

Benefits of EarthLinked® Over Gas Water Heating

Reduced operating cost up to 50%
Environmentally friendly renewable energy
No on-site fossil fuel firing
No combustion air supply needed
No flue gas venting
No explosion or asphyxiation hazard
No gas main needed

Benefits of EarthLinked® Over Air Source Heat Pump Water Heating

Higher efficiency due to constantly favourable renewable energy earth heat source
Can be located in mechanical room because of no need to circulate air over an exterior coil
Quiet operation resulting from total system enclosure and elimination of exterior fan and motor
Eliminates the exterior coil, fan, fan motor and capacitor, defrost timer, and ancillary wiring, making it mechanically and electrically simpler
Has greatly improved reliability and service life because of its simplicity and the stable temperature of this form of renewable energy

Application of the EarthLinked® System

The most economic application of the EarthLinked® system is to preheat large quantities of cold water.

Typically, the system provides pre-heated water to standard 120-gallon water heater tanks. As hot water is used, the preheated water is transferred to one or more commercial water heaters that further heat the water to the required use temperature, maintain that level, and provide redundancy. EarthLinked® thus becomes a powerful hybrid that increases system capacity and reliability.

How the Renewable Energy System Works

EarthLinked® transfers heat by circulating ozone friendly refrigerant in copper earth loops that are trenched or bored into the earth. The liquid refrigerant transfers heat from the constant temperature of the ground, through a patented flow control device to the compressor.

The compressor raises the refrigerant pressure and temperature, and routes the hot vapour to the heat exchanger. The refrigerant vapour, passing through sealed channels, transfers heat to circulating water. The water is heated and delivered to the hot water storage tank.

Proven Performance

Field testing by U.S. EPA verified up to 75% energy savings and avoidance of the emission of up to 7,000 pounds of NOx per ton of heat pump capacity each year, as compared to electric resistance water heating (up to 42,000 pounds of CO2 and NOx each year by a 6 ton system).

The EarthLinked® Water Heating system delivers the highest efficiency of any powered water heating system. It is a heat pump that harvests abundant renewable energy directly from the earth. The systems have been heating water since 1983, primarily as an option feature of heat pumps for space heating and cooling.

Their most economic water heating application is to heat or preheat water for large users such as motels, multi-family dwellings, healthcare facilities, food processors and restaurants.
