Geothermal Energy
A geothermal pump is a great renewable source of energy to do optimal heating or cooling. The system uses the natural heat stored within the earth to facilitate the heating process whereas the time of summer act as a sink to absorb the excessive heat. We offer geothermal services in Paphos.
Our heat pump system is a utility appliance that smartly makes use of the natural heat without posing any harmful effect on our environment. Heat pump offers benefits for your comfort, pocket and environment.
Green Air has taken the stride of moving in the direction of renewable energy sources to let the earth restore its natural and healthy form.
Different types of geothermal energy
What is Geothermal Energy?
Geothermal energy is thermal energy generated and stored within the Earth. Moreover, it is energy that determines the temperature of matter. Earth’s geothermal energy originates from the original formation of the planet (20%) and from the radioactive decay of minerals (80%). The gradient, which is the difference in temperature between the core of the planet and its surface, drives a continuous conduction of thermal energy in the form of heat from the core to the surface.
Geothermal energy producers work by tapping into naturally occurring steam or hot water to generate electricity. The steam or hot water is used to spin a turbine, which in turn drives a generator. Geothermal electricity is produced by using the earth’s heat to generate steam, which is then used to drive a turbine connected to an electric generator.
Advantages of investing in geothermal energy
Let’s discuss the advantages of investing in geothermal energy.
Geothermal energy exists almost everywhere
Geothermal heat may be accessible and used right away as a source of heat almost anywhere in the world. Low-temperature geothermal energy is the name given to this heat energy. Heat pockets at 150° C (302° F) are used to generate low-temperature geothermal energy. The majority of low-temperature geothermal energy pockets are only a few meters below the surface.
Different uses of geothermal energy
The energy generated by geothermal power plants and geothermal electricity can be used for a variety of purposes, including:
- space heating
- cooling
- generation of electricity
Baseload geothermal systems
Unlike other renewable energy sources, geothermal systems are “baseload” power plants that can generate electricity 24 hours a day, 7 days a week. Thus, this makes geothermal services in Paphos a reliable renewable energy source.
Types of Geothermal Heat Pump Systems
There are four basic types of ground loop systems. Three of these—horizontal, vertical, and pond/lake—are closed-loop systems. The type of heat pump system will depend upon the climate, soil conditions, available land, and local installation costs at the site. All of these approaches can be used for residential and commercial building applications. We can help you by offering geothermal services in Paphos.
Closed-Loop Systems
Horizontal
This type of installation is generally most cost-effective for residential installations, particularly for new construction where sufficient land is available.
It requires trenches at least four feet deep. And the most common layouts either use two pipes, one buried at six feet, and the other at four feet, or two pipes placed side-by-side at five feet in the ground in a two-foot wide trench.
The Slinky™ method of looping pipe allows more pipe in a shorter trench, which cuts down on installation costs and makes horizontal installation possible in areas it would not be with conventional horizontal applications.
Vertical
Large commercial buildings and schools often use vertical systems because the land area required for horizontal loops would be prohibitive.
Vertical loops are also used where the soil is too shallow for trenching, and they minimize the disturbance to existing landscaping.
For such a system, holes (approximately four inches in diameter) are drilled about 20 feet apart and 100–400 feet deep. Into these holes go two pipes that are connected at the bottom with a U-bend to form a loop. So, the vertical loops are connected with horizontal pipe (i.e., manifold), placed in trenches, and connected to the heat pump in the building.
Pond/Lake
If the site has an adequate water body, this may be the lowest-cost option. Because a supply line pipe is run underground from the building to the water and coiled into circles at least eight feet under the surface, it prevents freezing. The coils should only be placed in a water source that meets minimum volume, depth, and quality criteria.
Open-Loop System
This type of system uses well or surface body water as the heat exchange fluid that circulates directly through the GHP system. So, once it has circulated through the system, the water returns to the ground through the well, recharge well, or surface discharge. But this option is obviously practical only where there is an adequate supply of relatively clean water, and all local codes and regulations regarding groundwater discharge are met.
