What is geothermal energy?
Before talking about geothermal floor heating, We need to know what is Geothermal heating and cooling system?
Is an ultra-efficient technology that allows the use of free, sustainable ground energy to heat and cool a home. Geothermal heating is also referred to as a heat pump system of the soil source, and it involves heating into the natural surface temperature.
Geothermal energy is the energy in the Earth. The word geothermal comes from geo (earth) and thermal (heat) in the Greek language. Geothermal energy is a source of renewable energy, because heat is generated constantly in the earth.
Residential Geothermal Heating System
The adoption rate for geothermal cooling and heating systems is increasing significantly every year in the United States. It was reported that there is a truly growing general interest in the project of geothermal HVAC and installing of geothermal floor heating.
However, it is important to know if your geothermal floor heating is right for you before you can start installing a geothermal cooling and heat pump.
A geothermal heating and cooling system for your home should be suggested if:
- You are built a new home and can charge your mortgage the installation cost. In doing so, from day One of your new home, you will benefit from the lower energy costs.
- You plan to stay for around 4-7 years or 10-12 years in your new home (refit). This allows the initial installation costs to be recovered by saving energy and costs.
- There is a large lane field in your home with a large or deep pond This helps you to use a low-cost geothermal system.
Professional experience is needed in the installation and implementation of geothermal heating system, So you need to insure you contact a well-trained and well-experienced geothermal contractor who can help you find the correct solution for the case, as you decide to build the residential geothermal heating system.
Two types of geothermal systems
Today we use various designs; nevertheless, all heat pumps used on the ground source work on a similar basis. The energy is injected through the geothermal system between the surface systems and the energy source in the reservoirs either as an aquifer or as depth of the internal heat in the earth.
The design of the system itself is determined by different heat sources, with an aquifer using a open loop and systems based on the heat of the planet using a closed loop. either closed & open loop geothermal.
Based on a variety of factors, we choose the best geothermal residential heating system, geothermal loop length and configuration for a residential geothermal heating structure, these factors are: Local construction prices, cooling and heating requirements land available environments and climatic factors land accessibility,
Closed loop: horizontal or vertical loops of plastic tubing hidden under the building circulate heat exchange fluids constantly in ground-sourced closed loop system. This fluid collects latent heat from the earth and transmits it to a compressor and an indoor heat pump. The heat is absorbed and distributed into your house via an indoor spiral. Cooled fluid then moves to the loop area for more heat absorption. The ground functions as a thermal trap to absorb heat from the building for cooling in the summer.
Open loop: The external loop system is used for geothermal water supply systems. Water is pumped directly from a well or deep pond to the water heat pump in which latent heats are obtained from the water and then converted to refrigerant, the cooled water then is transferred to the source through a different well for discharge or pumped back to the pond directly. Open loop systems require a highly reliable supply of deep water.
Horizontal and Vertical loops
The horizontal and vertical geothermal floor heating are two of the most popular designs for geothermal heat pumps. Both systems are closed loops, which means antifreeze moves continually through the pipes of the system without leaving the system. To order to reach a comfortable temperature the heat pump transferred heat between this loop and the heat pump. Such pipes must be installed below ground in order to better transfer heat.
In residential areas, horizontal geothermal floor heating are usually used, especially where there is enough space available to support the installation, The heat exchange pipes are placed in the earth by a trench spanning about four feet deep. In order to create the closed loop system, pipes will lie side by side or at different depths.
Vertical geothermal floor heating usually utilize pipes that are installed standing along flat lying of larger buildings. This type of installation is typically used when horizontal installation is not practical because of the required space.
Why invest in a geothermal system for heating and cooling?
Geothermal Heating is a Sustainable and Renewable Energy
A geothermal heating system does not generate its power by burning fossil fuels such as gas, oil, or coal. Instead, it absorbs heat from within the earth, In contrast to a conventional electric heat-resistance generator, a geothermal heating and cooling system uses considerably less electricity. This makes a heating system for geothermal energy attractive to reduce the carbon footprint and to have a positive environmental effect.
Geothermal Heating Saves Money
Using a geothermal system, you can save significantly up to 80 percent of your energy costs throughout the year on your energy bill.
Geothermal Heating is Independent
A geothermal scheme, unlike other energy sources, such as wind energy and solar power, is more efficient than conventional heating systems and is not influenced by any external factors. Geothermal heating is not based on wind and sun but takes its heat from the earth’s still hot surface. It makes geothermal heating an energy source that is accessible and efficient.
Geothermal Heat Pumps are Highly Efficient
Geothermal heat pumps are extremely efficient because the energy from the ground is extracted from depths in which the temperature is constant
Geothermal heating and cooling are really a lot to like. Probably that is why it is the fastest growing renewable energy source in the United States for house heating and cooling. The geothermal efficiency impresses home owners – a geothermal system is 70 per cent more efficient than other heating methods in the heating mode – and has low environmental impacts.
Geothermal extracts latent heat, like a well or a pool, from the ground close to home or from a nearby source of water. Because underground and deep-water temperatures continue to be constant throughout the year, A heat pump may then focus this heat through your home in winter for heating. In summer the cycle is reversed by the loss of heat and the dispersal of water back to earth.
