Not too long ago nobody had even heard of geothermal energy, but it has recently increased in popularity as many homeowners are looking for ways to keep their homes cool and comfortable for less.
If you have been considering swapping out your conventional HVAC system with geothermal heat and cooling system, there are some important things that you should know. To begin with, let’s take a closer look at some of the “pros” and “cons” of this type of setup.
Highly efficient heating and cooling
Geothermal heating and cooling are not about producing heat or cooling the air. Instead, it is based on the concept of moving heat and this means it can operate anywhere between 300% and 500% efficiency. In other words, for every single unit of electricity used by the Geothermal heat pump, it can move three to five units of heat. This means that you can save as much as 30% to 60% on energy and as much as 50% on the costs of cooling.
Low environmental impact
As one of the world’s greenest forms of heating and cooling, Geothermal energy is completely emission-free. No fuels like gas, oil, electricity, or combustible fuels are required. A geothermal system still requires electricity, so it is not 100% eco-friendly. On the other hand, the geothermal system can be connected to a solar power plant making it even more environmentally friendly.
Renewable heating and cooling
The world has been dependent on the use of fossil fuels for powering every aspect of our technological and industrious civilization. But the geothermal system doesn’t work the same. As its name implies, geothermal energy extracts heat from the earth, because the temperature of the earth is more or less consistent throughout the changing seasons. As long as the earth is here and warm, geothermal energy will remain in use.
Not weather dependent
Solar and wind power are great because they are also sources of renewable energy, but neither of these sources of power is as reliable as geothermal energy. When the sun sets or the wind dies down, the power from solar and wind generators will be gone. But the earth is ever-present and will provide power to a geothermal system.
The major components of a geothermal heat pump will be installed below the ground. This means that there will be no noisy compressors or other mechanical components that will disturb the calm of your home. You will enjoy the peace and serenity of silent air conditioning in your comfortably acclimatized home.
CONS OF GEOTHERMAL ENERGY
Higher upfront cost than Conventional HVAC
You can expect to pay a considerably higher upfront cost for your geothermal heating and cooling system than you will for a regular HVAC. But because of the immense energy-saving value of the geothermal unit, you will be able to recoup your investment in as little as 5 to 10 years.
Most suitable for new home
It is more advantageous to have a geothermal system installed while the home is being built, to try and retrofit a geothermal system into an existing home can be a considerable task involving considerable excavation work.
If the subterranean features of your geothermal system have become damaged in any way, the costs to repair these components will be high. In some situations, shifting soil, tree roots and even the activities of burrowing rodents can cause problems that will result in a considerable financial setback.
How long do geothermal heat pumps last?
To be worth the price, a geothermal pump must be able to last long enough for the consumer to recoup their investment. The good news is that this can be accomplished in as little as 5 to 10 years and most geothermal systems will last up to 25 years with proper care and maintenance. The average HVAC has a service life of around 10 to 20 years depending on a variety of factors.
There are two reasons that a geothermal system lasts this long. First of all, the way these systems are set up allows for the costly components to be well-protected from the wind, rain, and attrition of the elements.
Because there is no combustion, the system itself is protected from the strain and attrition caused by open flames. Is that was a helpful solution?
