Product description of geothermal heating and cooling systems DC inverter water to water heat pump
Lower cost: A geothermal heat pump saves homeowners between 30-60% on heating costs and between 20-50% on cooling costs.
Fast return on investment: While geothermal systems can have higher initial costs than most other HVAC units, the overall cost savings will be seen within only a couple of years of your unit’s new construction.
Environmentally friendly: A geothermal system is one of the most eco-friendly ways to generate heat in and out of your home. Using less energy to operate, heat pumps lower your carbon footprint and lower air pollution caused by harmful greenhouse gases used in other systems. Quiet operation: There is no annoying noise when a heat pump turns on and off like with other types of units for heating and cooling.
Safe for you and your home: Since no combustive materials are used, a geothermal heat pump is safe to use and clean.
More comfortable: Geothermal heat pumps have been proven to improve the air quality in your home. If someone in your household has allergies or asthma, a heat pump unit will be much more pleasant as it operates to create an ideal balance of dehumidification and air purification.
Long lifespan: Indoor components of the heat pump can last up to 25 years, while the ground loop system can last up to 50 years. This significantly surpasses the lifespan of other HVAC units. Can be installed in all homes: Whether you install your heat pump in a new construction home or retrofit situations where there is existing ductwork, your home improvement efforts of installing a geothermal system will be well suited to any home environment.

Working principle of geothermal heating and cooling systems DC inverter water to water heat pump
Geothermal heat pumps are much like the heat pump in the refrigerator – its purpose is to absorb the heat from the earth loop and concentrate it to a high enough temperature so that it can be effectively transmitted to the condition spaces within the building.
Just like the refrigerator, it has a series of closed-loop tubing through which a refrigerant fluid is recirculated. The ground loop piping comes into close contact with cold – evaporator – side of the heat pump, transmitting some of its heat to refrigerant causing it to boil and vaporize and its temperature to rise slightly. The vaporized fluid is then compressed which concentrates its heat, raising its temperature dramatically as it passes to the condenser side of heat pump. Now the fluid is hot enough to transmit its heat to conditioned spaces within the building. Before the fluid returns to the evaporator, it passes through an expansion valve which drops its temperature below 30oF so that it can absorb more heat from the ground loop.
A series of by-pass valves (not shown in the schematic) enables the evaporator and the condenser to switch positions, converting the heat pump to air-conditioning mode.
Installation types of geothermal heating and cooling systems DC inverter water to water heat pump
There are several types of geothermal heat pump installations. Which type of unit will work best for your home will depend on the climate where you live, soil conditions, the size of your home that needs to be heated and cooled, and the local costs for the installation process.
Horizontal ground loops, vertical systems, and pond or lake loops are closed-loop systems that circulate heat through underground pipes. Open loop system pipes use a nearby water source like a well to circulate heat.
Horizontal system: Horizontal ground loops of layered coils and polyethylene pipes are buried in six-foot-deep trenches. This type of heat pump installation is ideal for approximately 2,000 square foot homes that have large ground space of up to 400 feet to build the trenches.
Vertical system: On properties with a limited amount of ground space, a vertical ground loop installation requires four-inch diameter holes to be drilled at 100 to 400 feet deep into the earth.
Pond/lake loop: Draws heat from a nearby lake or pond through a blanket of water that covers 10-foot-deep coils that are anchored onto racks to generate through the closed loop system.
Open loop: Open-loop pumps are water source heat pumps that use a nearby water source like a well. The pipe system cleans ground water to generate through the system and transform it into heat for your home.
