Geothermal Heating and Cooling

A house with a nice climate, while the heating and cooling system is not noticeable. This system operates well but does not require significant management or maintenance.

The air smells fresh; the birds will chirp and the wind moves through the trees gradually. Home shares energies with the World, in the manner in which the roots swap life’s basic elements through their leaves and branches. Doesn’t that sound comfortable?

Geothermal heating and cooling allow the vision a reality. Geothermal HVAC (heating, ventilating, and air conditioning) brings a building in harmony with the earth beneath, taking advantage of underground temperatures to provide heating in the winter and cooling in the summer.

How Geothermal Heating pump Works

The outdoor temperature changes with the changing seasons, but owing to the isolating impact on Earth, the subterranean temperature does not change too significantly. Temperatures remain relatively constant all year round, four to six feet below ground. An earth-loop geothermal device, which usually consists of an indoor handling machine and an entering piping network, and/or pump for re-injection, utilizes these constant temperatures to supply energy free.

The tubing that make up an earth ring typically form of polyethylene and can be placed horizontally or vertically beneath the ground, depending on the site’s characteristics. When a groundwater exists, engineers may recommend the construction of a “open-circuit” system in which an underwater water well is drained. Steam is heated out, pushed over the heat exchanger and the vapor is “reinjected” down to the same aquifer.

In winter fluid circulates or absorbs accumulated heat from the ground into an earth circle, and transfers it indoors. It is the indoor system that compresses and distributes the heat to a higher temperature all over the house, as if it was a reverse air conditioner. During the season, the HVAC geothermal device draws heat out from the house and drains them into the Earth / Aquifer into the Earth loop well for reinjection.

Geothermal HVC systems don’t burn fossil fuels to generate heat, unlike standard heating and cooling systems; they simply transfer energy from and to ground. In general, only the supporter, compressor and pump machine are supplied with electricity.

Little maintenance is expected in geothermal systems. The buried loop will last for generations when properly and strategically mounted. Fans, compressors and pumps of the machine are located inside, protected from the extreme weather environments, and are thus mostly employed for decades to several years. Daily monitoring, filter adjustments and regular belt cleaning are typically the only maintenance necessary.

Advantages of Geothermal Energy

Geothermal Energy is Environment-Friendly

Without using fossil fuel, geothermal energy is extracted from the upper crust. Geothermal systems do not contain pollution or have low emissions. Geothermal capacity may also be beneficial for eliminating up to 80% of traditional energy sources in terms of costs.

Huge Potential

The overall world energy usage, which corresponds to almost 15 terawatts (TW), is far from the massive energy reserves beneath the planet.


The total ability of geothermal energy generated by geothermal power stations is expected to differ between 0.035 and 2 TW. However, most geothermal projects aren’t productive and only a limited part of the total potential can be used.

Renewable Source of Energy

An additional benefit of geothermal energy is that it is a continuous source of energy compared with other renewable energy sources such as wind, solar or bio-mass. This energy does not depend on wind or sun, but is still available.

Geothermal energy, in comparison to traditional energy sources like coal and fossil oil, is a sustainable energy source that can maintain the usage volume. As experts claim, electricity is going to last billions of years in the earth’s geothermal reservoirs.

Highly Efficient

Geothermal energy is one of the main sources of energy when it comes to production. Geothermal heat pump systems use approximately 25% and 50% less fuel than standard heating and cooling systems.

Thanks to their modular nature, geothermal systems may also be adapted to various conditions which need less hardware space than traditional systems.

A Stable Energy Resource 

The performance of a geothermal system is relatively easy to estimate. The energy variations in the wind or the solar system are not the same.

Conventional power projects rely largely on fuel, so cost fluctuate according to the fuel price of the market for electricity produced. Nevertheless, geothermal energy projects are not exposed to the same condition as they do not use fuel.

Unlimited Supply

Unlike conventional energy sources, including coal and fossil fuel, there is no lack of geothermal resources. Geothermal sources are renewable resources that are recharged by themselves.

Cost Savings

Increased geothermal energy use ensures fewer traditional energy use for heating homes and workplaces, which contributes to substantial savings for homeowners.

After the initial construction cost the money is typically recovered in a couple of years, 30-60% savings on heating and 25-5% savings on cooling.

Disadvantages of Geothermal Energy

Greenhouse Emissions

While geothermal energy has been reported to be a environmentally sustainable source of energy, it still causes some pollution problem.

Geothermal energy is collected just under the grounds and greenhouse gases such as carbon dioxide and sulfide hydrogen, methane and ammonia are produced. However, in comparison with fossil oil, the gas levels are significantly smaller.

High Investment Costs 

Geothermal energy production will result in high initial costs for households. The procedures such as drilling and construction are complicated and the costs are very high.

Land Requirements

Installing geothermal systems requires a piece of land close to the house. Due of insufficient land it is particularly challenging for homeowners in large cities to introduce. A vertical heat pump is needed in these cases.

Geothermal heating and cooling cost

The expense of the re-installation of the GSHP can vary based on a variety of variables, including the type of system, your home size and your property’s physical features. By contrast to other methods of heating and cooling, the expense of modularizing will always more than justify the long-term benefits in geothermal systems.

Type of ground loop

There differed costs for three major forms of soil loops–horizontal, vertical, and pond / lake. The easiest alternative is typically a lake / pond chain, but a lot of water on your land is required to ensure that this is a feasible choice.

For GSHP installations, horizontal and vertical ground loops are far larger, so the form of built would depend upon the property’s space accessible. Horizontal geothermal ground loop systems are the most predominant residential geothermal alternative and are usually cheaper than vertical loop systems, owing to lower installation labor costs.
