Your Guide to Residential Geothermal Heating

When we talk about “residential geothermal” we talk of the electricity in the rock and waters of the Earth’s crust. Geothermal energy is commonly used in two ways: for heating or for generating electricity.

A geothermal heat pump, also known as GSHP, works in many ways as the usual heat pump, with a difference only: instead of transferring power between a building and the outside environment, there is a transfer of energy from the building to the ground. Geothermal heat pumps transfer heat energy from the heat source (the ground) when heating is needed. Like normal heat pumps, when we want cooling, this cycle can be reversed. Geothermal heating is the technically correct concept to use, because when the building is cooled in theory, the earth is heated immediately. Among other factors, efficiency is calculated by differences in temperature.

High temperatures are not dependent on geothermal heat. Therefore, geothermal heat pumps are much more economical than geothermal power stations requiring a high-temperature water and steam to generate electricity.

Geothermal heating and cooling systems could therefore be found almost anywhere, they used in homes and they called residential geothermal.

Is geothermal energy available everywhere?

Almost anywhere you can find geothermal energy, but in a few areas, it is definitely easier to access than others. Regions rich in hot springs and other natural hot water sources can find and use geothermal, particularly to a larger extent, more easily. But, can we use geothermal energy as residential geothermal in our houses?

Residential Geothermal

Geothermal home system can be an ideal way to heat and substitute a furnace, which are classified as savers of energy. Problem is, is the excitement worth it?

The earth’s temperature from depths of 6-10 meters no longer is influenced by surface temperature variations, but remains fairly stable at about 8-10 C. The basic principle of Geothermical Heating and Cooling is to use this constant temperature inside the planet to produce the electricity. With the use of heat pumps, geothermal heat and cooling systems, you extract and transfer heat energy to houses, saving between 50-60% of heating and cooling costs, depending on which fuel you compare.

Geothermal cooling operates closely to traditional air conditioning during the summer months, except heat is not simply extracted into the outdoor soil, but stored directly into the earth for future purposes.

In most parts of the United States they use residential geothermal, it functions to heat your home for winter (if external air temperatures are usually cooler than the ground temperature), However, this also goes on in the summer when the weather in the ground becomes warmer, and when the water pumped into the earth cools the room, Your house is warm/cool all year round! And it’s more effective to use geothermal energy for homes than using electricity/gas/oil, because it doesn’t need to move heat just from one origin to another.

Greenhouse Heating Systems

We can also use geothermal energy in agriculture as geothermal heating greenhouse, In most areas of the country there is low temperature energy economic choice because it provides a reasonable refund, normally of 10 years or less, depending on the system design and the prices of the substitution of fossil fuel. Before considering installing your geothermal system the estimated payback for your scenario should be carefully calculated and energy conservation.

Air systems

Ground tunnels are tubes found under the surface of the earth 6-12 feet deep. The simplest and cheapest devices capture heat in the winter by extracting air from corrugated plastic tubes and guiding it to the heated room. The soil, which has a higher temperature, heats the air passing through the tubes. During the summer, it can be used to cool building space through the buried tubes by drawing outdoor air in the greenhouse.

Fluid systems

Residential Geothermal Heat systems usually warm up a heat like propylene glycol or methyl alcohol in a closed-circuit device from which electricity is collected, using the soil or moisture of a well, pool, or other body of water. Horizontal loops can be used to capture heat from the gound, if enough land is available. In trenches up to 400 feet are placed pipes the amount of heat needed for heating the greenhouse(s) is reported through multiple loops.

Reasons You Should Use a Geothermal Cooling System for your home

Geothermal energy systems in other words are completely sustainable and use 100% renewable energy. All right, just pay attention now. There are four reasons why a geothermal heating and cooling system should be considered.

Energy Savings

Geothermal cooling systems ‘ energy saving is the first reason to take this type of technology into account. The average energy expense of a geothermal heat pump is 30-70% decreased. Homeowners are therefore usually able to recover the costs of a geothermal plant in 5-7 years by saving energy.

Cooling and Heating

There are many applications around the building in a geothermal system It provides not only energy-efficient ventilation, but it also offers all heating and cooling through a single system. Hot water heating and pool ventilation can also be used with geothermal heat pumps, Geothermal heat pumps may reduce maintenance costs as a heating and cooling system, because less parts are able to break.

Always Producing

Geothermal production is stable compared with other forms of green energy systems. Solar heating and cooling devices for instance can obtain electricity at normal hours of sunlight. Can windy days run wind-powered systems, Due to the secure underground temperature, a geothermal system operates always Such devices are always able to transfer energy and make it suitable for home heating and cooling.

Energy Efficient

Most households and businesses have made their carbon footprint targets less energy efficient. And these targets can be provided by a geothermal heat pump. This is one of the most successful cooling systems on the market.

Others

The Residential geothermal systems of today are more effective at a lower cost than they were a few years ago. In response to recent volatility in fossil fuel prices geothermal heat has become increasingly popular in residential and commercial applications. Because of the higher temperatures typically required for greenhouse heating, geothermal systems may require a heat pump. If low temperature heat is required, for example, maintaining an air temperature just over freezing, it is possible to directly use the heat. The payback for alternate heating systems is reduced when the cost of fossil fuels is raised.
