How Is Geothermal Heat Pump Installed?

Before we get into the installation process of geothermal heat pumps we need to understand what geothermal heat pumps are actually. Geothermal heating pumps, are central heating or cooling systems that transfer heat to and from the ground. Unlike many other heating or cooling systems, the geothermal heat pumps uses the earth as the heat source during the winters and heat sink during the summers. Compared to other heating and cooling systems the geothermal heat pumps largely reduce the heating and cooling costs of the houses. The best thing about geothermal heat pumps is that they can be installed in buildings which has existing system such as traditional forced air or the radiant floor heating. At the same time, it can also be installed in a completely new building.

When you decide to install a geothermal heat pump in your house you should keep in mind that the size of the geothermal heat pump and the size of the ground loop solely depends on the heating and cooling requirement of the house. However, choosing the right size is critical because that determines the efficiency of the system after it has been installed. Generally, the capacity of geothermal heat pumps is measured in tons and it has been noticed that a system with a 3 ton capacity is enough for an average home. However, a lot of other things like size of the house, heating and cooling requirements of the members, local geology, and soil and land availability also affects the capacity of the geothermal heat pumps.

When it comes to the installation of geothermal heat pumps in the United States it has been seen that in most of the places, shallow ground temperature is a common factor and so geothermal heat pumps can be effectively used almost anywhere. Nevertheless, to get the best solution factors like geological, hydrological and spatial characteristics of the land, need to be studied by the supplier. One must keep in mind that specialized technical knowledge is needed to install a GHP (geothermal heat pump) and so it is not at all a DIY project. The installers, you choose should be adequately experienced and certified. You can use references from the ones who have already installed the system for a qualified installer.

The advantages of getting in touch with an expert installer are that they will study all the necessary factors carefully so that you get the most energy efficient heating or cooling systems. An expert professional installer needs to have good knowledge of geology, hydrology and land availability.

This is important because soil, which has a good heat transfer property requires less amount of pipe to gather the same amount of heat than a soil which has less heat transfer properties. At the same time the amount of soil that is available in a particular area also impacts the design of the soil.

Secondly, the ground or surface water availability also plays an important role in determining the kind of loop which has to be used. The depth, volume and quality of the water can be used as a source of water for an open-loop system or as a repository of coils of piping in case of a closed-loop system.

Last but not the least, the availability of land also plays an important role in determining the design of the geothermal heat pumps.

It must be noted here that the installation price of the geothermal heat pumps varies depending on the type of loop system which is the vertical loop or the horizontal loop system.
