We understand how profitable the geothermal heating of a private house

Imagine having a home heating system that not only keeps you warm during the coldest winters, but also helps the environment and saves you money. That’s precisely what geothermal heating provides: an affordable, environmentally friendly way to harness the heat that naturally exists on Earth. In this piece, we examine the benefits of geothermal heating for individual homes and investigate the reasons behind its growing popularity among homeowners seeking to modernize their heating systems.

Geothermal heating uses the constant temperature of the Earth beneath our feet as opposed to conventional heating techniques, which rely on burning fossil fuels or electricity. Geothermal systems provide year-round comfort by extracting heat from the ground in the winter and returning any excess heat to it in the summer through the circulation of a water and antifreeze mixture through a network of subterranean pipes known as a "ground loop."

The exceptional energy efficiency of geothermal heating is one of the strongest arguments in favor of this technology. Geothermal heating systems function reliably in all weather conditions above ground, whereas conventional heating systems find it difficult to remain efficient in extremely high or low temperatures. Geothermal systems have the potential to save homeowners up to 50-70% on their heating and cooling expenses when compared to conventional systems; this stability translates into substantial energy savings.

Furthermore, compared to traditional heating techniques, geothermal heating systems have a negligible negative environmental impact. Homeowners can significantly lower their carbon footprint and help to mitigate climate change by using renewable geothermal energy. Furthermore, since geothermal systems don’t emit any emissions locally, they help to improve air quality and lessen reliance on finite fossil fuels.

In addition to its financial and environmental advantages, geothermal heating provides homeowners with increased dependability and comfort. Geothermal systems function quietly and have fewer moving parts than furnaces or air-source heat pumps, which can be noisy and need frequent maintenance.As a result, homeowners can have more peace of mind and pay less for maintenance.

The use of geothermal heating in private homes is expected to significantly contribute to lowering energy costs and halting global warming as we move toward a more sustainable future. For many years to come, homeowners can benefit from affordable, dependable, and eco-friendly heating solutions by utilizing the Earth’s inherent heat.

Advantages and disadvantages of geothermal heat pumps

Heat pumps have been used extensively and—most importantly—for a long time in Russia. Users were split into two opposing groups: those who commend the heating system (which also includes sellers and installers) and those who are against it because of malfunctions or dishonest installation firms.

We can make judgments about the benefits and drawbacks of heat pumps based on the reviews.

The benefits are demonstrated by excellent design, wise equipment selection, and adherence to installation guidelines.

Choosing geothermal heating for your house is a wise decision. You can lower your carbon footprint and energy costs by harnessing the Earth’s natural heat. Geothermal systems need less upkeep and are much more efficient than conventional heating techniques. In addition, they consistently provide warmth throughout the year, regardless of the outside temperature. Investing in geothermal heating is an environmentally friendly and sustainable choice in addition to being economical. Bid adieu to erratic energy bills and welcome to comfortable, environmentally responsible living.

Device and principle of operation of geothermal heating

Using a split system or domestic refrigerator as an example, you can see how the heat pump functions. The freezer’s walls will be cooling while the refrigerator’s rear radiator, which is heated to the touch, remains hot.

Similar to this, the air conditioners arranged throughout the area function: the outer block drops the street onto the street, while the inner unit cools and provides a source of coolness. The split system heats the room’s air when it is in reverse mode.

When a thermal pump is used for heating, heat is extracted from the air, soil, or water by the external unit, which is connected to external contours laid in the pipes. Pumping water is possible in water circuits; in this instance, the input and output are situated roughly 20 meters apart. Heat enters the house after changes in the central block.

The following are the components of the geothermal heating system:

1. Directly the heat pump with a compressor, evaporator, condenser and throttle valve.
2. The contour of low -temperature heat.
3. The contours of the heating of the premises (water or liquid) and water heating.

The work is based on the research of Nicolas Leonar Sadi Carno, a well-known scientist who examined thermodynamics early in the field’s development. The work’s algorithm is as follows in detail:

1. The coolant of the outer circuit is pumped through the pipes. During movement, the liquid heats up several degrees from the heat of the earth, water or air.
2. The outer circuit passes through the heat exchanger, where the refrigerant heats up, for example, Freon, which evaporates. In addition, the refrigerant enters the evaporator through the capillary hole and expands sharply, which also helps heating.
3. The compressor compresses the heated refrigerant, increasing the temperature of the freon.
4. Hot compressed refrigerant enters the capacitor, where, cooling and turning from steam into liquid, it gives heat to the heating system to the coolant, which is already circulating through heating pipes. Another option – heats the air that is distributed through the premises.
5. Further, the refrigerant again enters the evaporator, where it is heated by a new portion of the coolant circulating in the outer circuit.

People frequently wonder where heat pumps’ 300–700% efficiency comes from. This is because soil (water, air) heats the coolant of the outer circuit, which "picks up" some of the energy from outside sources, from -15 to +7 degrees Celsius when it exits the pump. The heat from the outside causes the refrigerant in the pump to evaporate in addition to costing the compressor.

Crucial! The precise temperature of the coolant in the outer circuit may vary depending on the equipment used, but the coolant needs to be heated by a minimum of 2-4 degrees in order for the heat pump to function. If not, there is no economic impact or perhaps a negative one.

Methods of organizing geothermal heating

Several indicators are used to categorize geothermal heating systems:

1. Combinations of the environment of the external circuit and the type of coolant of the internal circuit.
2. The method of laying thermal probes (contours) in soil or water – vertical or horizontal.

The equipment manufacturer specifies the first parameter. For instance, a standard split system falls under the air-to-air category and transfers heat from the outside air to the building.

The liquid coolant in the heating system is heated by the "soil-water" pump, which harnesses the heat from the earth. The "Water-Athos" parameter suggests a design solution where the house’s heat is dispersed by heated air streams and the outer circuit is submerged in water (an external pond or a well).

The operating conditions determine which method is best.

Rationale for the choice of class class

When purchasing heat pumps, one of the primary factors considered is the coefficient of transformation, or COP (COEFFICIENT OPERANCE). In other words, one kilowatt of electricity can be converted into one to seven kilowatts of thermal power. It is crucial to realize that the actual coefficient of the geothermal thermal pumps will be lower than the one stated in the passport because the longer the project takes, the more electricity will be needed to pump the coolant along the outer contour.

In actuality, users report that if you record for the full duration of operation, you should expect a burden of 2.5–3.2. This is because the temperature of the water and soil varies gradually based on the weather.

The location of the environment—from which heat will rise—depends primarily on the region’s climate and the geology of the construction site.

It is best to select equipment with an exterior contour situated in the water if:

• The reservoir is a private pond;
• The depth of the well to groundwater does not exceed 20 meters (in some regions up to 45 meters).

If these terms are not followed, a license is required in order to use subsurface. When regulatory bodies check for a license, the equipment will need to stop and pay a fine of up to several million rubles.

Furthermore, the distance between the reservoir and the house is crucial; if it is greater than 25 to 30 meters, the efficiency will be significantly decreased, necessitating the expenditure of additional coolant pumping and pipeline insulation.

It is not forbidden to install the outer circuit in the designated area of soil, but you must arrange the pipes correctly, either vertically or horizontally.

Up to 50 watts of thermal power can be extracted from one meter of horizontal pipe, depending on the makeup of the soil. This is accurate for clay soils, though. Sandstones and loams can provide 12 to 25 W/m, and an external horizontal circuit with a length of 200 to 700 m may be required for a heat pump with a 10 kW capacity. You will need a plot of 450 m 2 for its placement. Ring-shaped pipes are ineffective because the coolant cools the soil around them, making it impossible for the rings next to them to warm up.

Crucial! Since the coolant is already less heated in the winter, the soil gradually freezes, gets colder, and the grade drops by February or March.

After a few years of operation, the owners of the sites where the thermal pump’s horizontal circuit is located report that the soil structure has changed, vegetable plants have grown worse, and the area is only used for lawns. Strong root systems discourage trees from planting where they could damage the pipes.

The best puncture or well system is thought to be vertical, with multiple contours positioned to diverge in various directions. The Earth’s temperature is more stable and less dependent on the climate at great depths. Collectors are positioned in a well that is equipped for the pipe ends. The wells are positioned around the circle and drilled at an angle to the horizon; this reduces the impact of each circuit on the others.

Can everything be done with your own hands

In theory, it is possible to put together a geothermal heating system, but in reality, it is challenging, if not impossible.

A significant amount of earthwork will be required for the contour to be laid horizontally. The pipes are positioned at least 0.5 meters below the soil’s freezing point, i.e. You must excavate the ground to a total depth of two to three meters. Throughout the pipe-laying process, the soil needs to be kept in storage.

It is not feasible to drill wells with a total depth of up to 200 meters without specialized, pricey equipment; this amount of work cannot be completed by hand. Only if you have the technical means to use an excavator, dump truck, bulldozer, or drilling rig should you begin laying the contour on your own.

There are many advantages to switching to geothermal heating for your home, both environmentally and financially. Geothermal systems eliminate the need for extra energy sources by using the earth’s stable subsurface temperature to provide reliable heating all year round.

The long-term cost-effectiveness of geothermal heating is among its most alluring benefits. In comparison to conventional heating systems, there may be a higher upfront cost, but there may be substantial long-term energy bill savings. Homeowners can save a lot of money on their heating bills thanks to lower operating costs and less maintenance requirements.

Furthermore, by drastically lowering carbon emissions, geothermal heating systems help to create a more environmentally friendly world. Geothermal systems use the heat from the earth as a renewable energy source, so they have a smaller ecological footprint and produce fewer greenhouse gas emissions than fossil fuel-based heating methods. Homeowners can actively contribute to lowering their carbon footprint and mitigating climate change by switching to geothermal heating.

In addition to being more cost-effective and environmentally friendly, geothermal heating provides homeowners with increased dependability and comfort. In contrast to conventional heating systems, which might have temperature swings or need frequent adjustments, geothermal systems offer reliable, even heating throughout the house. Regardless of the outside weather, a comfortable living environment is guaranteed by this steady temperature control.

The benefits of geothermal heating for individual homes are evident and strong, to sum up. Geothermal systems are a wise investment for homeowners because of their many advantages, which range from cost savings and environmental sustainability to improved comfort and dependability. Geothermal heating uses the earth’s natural heat energy to lower energy costs while also making the planet a healthier and cleaner place for coming generations.
