Geothermal heating by Aesum on Flickr.Installing geothermal heating in your home can be a good way to take advantage of renewable home energy while improving your comfort. Before you decide whether geothermal energy is the right choice for your home, learn what is involved.

When first considering a geothermal heat pump, many people wonder "What is geothermal energy?" Geothermal heat is actually just heat that comes from the earth. Geothermal heat pumps make use of a heat sink during the summer months and groundwater as a heat source during the winter months.

A heat pump is utilized in order to transfer heat from one location to another location. This makes it possible to transfer heat from below the ground to your home.

If you opt for this type of heat pump, air conditioning can also be taken advantage of in your home.

If you are considering having geothermal heating installed in your home, it is a good idea to obtain more than one estimate. When you ask contractors to provide you with an installation estimate, make sure to ask specifically what is included. In particular, find out whether a warranty is included.

In considering geothermal heating cost, the cost of drilling will need to be included in the total cost of the final project. The cost of drilling to install geothermal heating systems may vary based on your local terrain.

It is also a good idea to compare the costs for heat pump prices.

When you are obtaining estimates, be sure to ask which type of ground loop system will be used. There are four different options:

    • Horizontal.
    • Vertical.
    • Pond/lake.
    • Closed-loop.

In addition to providing excellent energy efficiency, geothermal heat pump systems can provide a number of other benefits. Such benefits include durability and requiring very little maintenance. One of the reasons for this is that most of the components required in this type of system are located underground.

Ductwork is used to distribute both cool and warm air throughout the home, much in the same way that a traditional home cooling and heating system works.

A geothermal system does differ from a traditional AC in that there is no exterior condensing unit used. As a result, a geothermal heating system is often much quieter than an air conditioner.

If you are not certain whether geothermal heating is the right choice, you may wish to consider comparing this option to traditional heating and cooling systems. An experienced HVAC professional should be able to provide you with an estimate to install a regular central heating and cooling system so that you can make an accurate comparison.

Geothermal heating is a good option if you are looking for an efficient and renewable heating and cooling source for your home. By comparing options, you will be able to determine whether geothermal heating fits your budget and your lifestyle.
