Geothermal heating and cooling
The power of nature is unimaginably large. Heat pumps for heating and cooling have too much to offer to the market, and there’s no end in sight to the technical developments. Today, the heating market is on the move. While solar thermal collectors are not competitive in space heating, geothermal heat pumps demonstrate the high application in comfortable living.
For most homeowners, heating and cooling are based on large energy expenditures, and just one geothermal heat pump can diminish it all, avoiding any distortion caused by different outdoor temperature levels.
How does a heat pump work?
Heat pumps are taking energy from the external environment. Therefore, input in a heat pump is the temperature that will be converted into lower or higher, depending on if it is used to cool down or heat your space. When external thermal energy enters the pump evaporator, the gas, that is becoming a medium, accepts that energy and flow towards a compressor that raises its pressure and temperature. In the heat exchanger, the gas transmits the temperature to the system, and it cools down and returns to the beginning of the process. The heat circulates through the floor or radiator heating system and heats the space. In the case of the cooling work system, the heat pump is delivering cooling energy to the system.
Some types of heat pumps have a special feature – the system controller’s ability to evaluate the information that is continuously collected on user behavior and the weather and to adjust itself correspondingly.
Heat pumps are bringing back energy efficiency on the big door while improving home living throughout all seasons. Heat pumps are considered the most efficient electrical device. The main characteristic is that for every 1kW of electrical/temperature energy input, heat pumps are delivering 5 kW of heating or cooling energy. No matter how hot summer days are, or chilly in winter, the heat pump will make it pleasant inside, without astronomical electricity bills at the end of the month.

Types of heat pumps
Heat pumps are using existing temperature level from three outdoor sources:
- air
- groundwater or surface water
- earth
Unlike air temperatures, which fluctuate depending on the time of year and time of day, the temperatures of underground water, surface water, and from the earth are mostly constant, and their values range from 53 ⁰F to 57 ⁰F, in every season. This feature makes air heat pumps less energy efficient than water or earth heat pumps. Air heat pump utilization coefficient is lower, and every air temperature that is lower than 5⁰F converts a heat pump into an ordinary electric boiler.
Symbol of the energy revolution
In numbers, heating or cooling an indoor space with a heat pump enables up to 50% lower energy consumption, while improving the quality of living. Geothermal heat pumps are considered a renewable energy source, and, unlike solar, their energy source is always constant.
Geothermal heat pumps have what it takes for long-term attractive benefits – performance stability, durability, reliable and silent work. The lifespan of a heat pump is mostly 20 years, and installed pipes could last for up to 50 years.
Determination to grow more independent of energy imports are driving the expansion of renewable energies. A geothermal heat pump can provide energy efficiency that you can feel.
