Geothermal Heating

The systems that use the earth as a source of heat are called geothermal heating systems. These systems fulfill the purpose of heating the indoor spaces. Not only do they heat but help to cool the buildings during summers.

These heating systems save a lot of energy. As a result, they help you save a huge sum of money every month. Isnt that great? Well, there are more benefits so lets find out what these are.

These systems reduce pollution as they are environment friendly. This is a reason for its popularity with most buyers who are conscious of the environmental impact of their purchases. Because of its environment-friendly quality, geothermal systems are most commonly used in homes, offices and even schools.

A series of pipes called 'loop' connect the heat pump of the system to the earth. There are different types of systems that are available and are mentioned below.

1)Open Loop Systems-These are the simplest of all geothermal systems. These have been used for a number of years. Ground water is drawn out from an aquifer via one well. It passes through the heat exchanger of the system. It is further discharged in the same aquifer via a second well which is at a distance from the first. These systems with open loops are a common option because the temperature of the ground water is constant all through the year.

2)Closed Loop Systems-Closed loop systems are economical, reliable and efficient if they are installed properly. In recent times, they have become quite common. In these systems, water circulates through buried pipe. The length of piping varies and depends on the ground temperature, soil moisture and system design.

3)Horizontal closed loop-These are the most cost effective and works quite well in new construction, where sufficient land area is available.

4)Vertical Closed Loop Systems-These systems are used when the soil is shallow for the trenching purpose and to reduce the disturbance in landscaping. In a well that is 199 to 400 feet deep, a U tube is installed.

5)Slinky Loops-These loops are used to increase heat exchange per foot of the trench. As the number of pipes increases, the trench length decreases.

6)Pond Closed Loop-It is a special system used in geothermal systems. Closed loop coils can be placed on the bottom of the pond where there is a pond and is deep and also has enough flow. The fluid is pumped in these systems in the same way as the traditional geothermal systems. The best part is that these systems dont harm the aquatic life of the ponds. This is because it is very attractive in terms of economics.

There are a variety of geothermal heating systems available. You can choose what works best based on the suitability and requirement. These systems are also eco-friendly and extremely economical. Therefore, these systems are more commonly used these days. So go ahead and buy one for yourself. Enjoy the advantages!
