We all imagine a house with a comfortable temperature, thanks to a proper heating and cooling system. Ideally, this system should efficiently work without the hassle of extensive maintenance. There are two ways of achieving this – installing Electrical Heat Pumps and Geothermal HVAC systems. Both have their usefulness, but it is efficiency that matters the most. Over the years, Geothermal HVACs are more efficient compared to Electrical Heat Pumps. Therefore, the real debate is over Geothermal HVAC’s efficiency versus the inefficiency of an Electrical Heat Pump.
Before moving ahead, one must be aware of some basic differences between the two.
Geothermal HVACs: The change in the seasons causes fluctuation in the temperature, but the change in temperature underground is less drastic due to the earth’s ability to insulate. Throughout the year, the temperature is more or less constant few feet below the ground because the earth absorbs a great amount of solar energy. Geothermal HVACs (Heating, Ventilating, and Air Conditioning Systems) are structured to take advantage of this. Through the indoor unit and a system of pipes buried underground called the ‘earth loop’ or a ‘pump to reinjection well’, the system exchanges free energy with the earth, thereby providing Geothermal heating and cooling atmosphere to the homes with incredible efficiency.
Electrical Heat Pumps: They basically function as a furnace, which provides heat during the chilly weather. These pumps are also capable of maintaining heat during the winter, thanks to the air conditioning system. They generally operate either on gas or electricity.
Once both the concepts are cleared, we can analyze the efficiency of Geothermal HVACs versus the inefficiency of Electrical Heat Pumps.
Cost: The first thing that makes the Geothermal HVAC the preferable option is its cost. Electrical Heat Pumps are quite expensive to purchase and maintain over a period of time. A Geothermal HVAC, on the other hand, will cut up to 80% of hot water, cooling and heating costs.
Maintenance: Maintenance is another issue when it comes to Electrical Heat Pumps. They require constant attention and maintenance. A Geothermal HVAC can last for generations with little maintenance, once installed properly.
Environmental concerns: In Electrical Heat Pumps, some fluids that are used for transferring heat are not entirely environmentally friendly. Plus, since these pumps solely run on electricity, they can never be carbon neutral. Compared to this, Geothermal HVACs use one unit of electricity from underground to the building. Also, Geothermal HVACs utilize the heat from below the ground, a naturally inexhaustible and environmentally friendly resource.
