Imagine you have a household in which the temperature is just right, but the heating and cooling system is nowhere to be found. Not in the kitchen, not at the back. The system is highly effective while requiring little to no maintenance, which makes it a little attractive. It does not even require the owners or any members of your household to know anything about it. And yet, it perfectly suits your home.
According to drill rig companies, that idea is not a figment of the imagination anymore because it has finally become a reality, owing to geothermal heating and cooling.
Geothermal HVAC (heating, ventilation, and air conditioning) unites a structure (in this case, your house) with the ground underneath it, utilizing subterranean temperatures to deliver heating in the winter months. But come summertime, it provides cooling features instead.
As part of the rising green construction revolution, geothermal HVAC systems are fast becoming typical components of eco-friendly homes. Last year, green environmental buildings accounted for 20% of all newly built dwellings in the United States alone.
But it is kind of disturbing that most of the information available about geothermal heating and cooling is out of date, or simply a myth. Therefore, they are not worthy of belief and thus we need to debunk them once and for all.
Here are some of the busted geothermal HVAC myths you need to know now.
Myth: Because geothermal HVAC systems use energy, they are not considered renewable technology.
Fact: Geothermal HVAC systems require only a single unit of power to transfer up to five units of heating or cooling from the underground to a structure, building, or your house.
Myth: In comparison to geothermal HVAC systems, wind and photovoltaic electricity are more economical renewable technologies.
Fact: Top drill rig companies assert that geothermal HVAC systems eliminate 4 folds more kilowatt-hours from the electrical grid for every dollar used in the system compared to wind and solar generation.
Sure, other technologies can help, but geothermal HVAC systems are usually the most cost-effective approach to decreasing the impact on the environment as far as cooling/warming space is concerned.
Myth: To support the polyethylene pipe earth loops, geothermal HVAC requires a large amount of real estate or backyard space.
Fact: With regard to the features of the site, the earth loop can be vertically sunk. This will make it require only a small amount of above-ground surface. Alternatively, if it is at all possible to tap into an existing aquifer, it will only take several square feet of above-ground space.
Understand that the water is returned to the aquifer from which it came after passing through a heat exchanger. Therefore, technically speaking, it is erroneous to say that it “used up the water” or otherwise adversely impacted the water.
Myth: Geothermal HVAC systems are solely capable of providing heating mechanism.
Fact: Geothermal HVAC is just as effective at cooling as they are at heating, and they can be designed in such a way that they do not require a backup heat source if that is what the customer prefers. However, some customers find that it is more economically viable to have a small backup system intended for use only during the coldest days if it means that their loop can be smaller in overall size.
Myth: Geothermal HVAC systems can’t simultaneously heat water, swimming pool equipment, and a dwelling.
Fact: This system can handle all that, plus more. It can take in a number of loads all at the same time.
Myth: Geothermal HVAC systems consume a huge amount of water.
Fact: Geothermal systems do not even require water to operate. If aquifers are being used for heat exchange purposes with the earth, any water that is extracted from the earth is restored to the same aquifer.
Before there were the “pump and dump” procedures that culminated in water being lost after going through the heat exchanger, fortunately, these are becoming scarce now. Standard HVAC systems evaporate millions of gallons of water every single year.
Now compare that to geothermal HVAC solutions, this water wastage is avoided by utilizing geothermal heat pumps rather than cooling towers.
