Geothermal heating systems


Geothermal heating systems

As our focus shifts towards cleaner, lower-impact sources of energy, the conventional technologies we use to heat our homes or commercial sites have proved unsustainable. Between the rising cost of fossil fuels and the harmful impact of their emissions into the atmosphere, it is clear the wisest course is to turn away from heating and cooling our structures with oil or gas systems.

Geothermal heating and systems have emerged as the clear winner among renewable alternatives. While solar, passive house, or windmill systems accomplish the same emissions reductions, geothermal technology surpasses them all in terms of cost, maintenance, reliability, and effectiveness.

Use of these technologies in the residential and hospitality sectors is further encouraged by their health and aesthetic benefits as compared to conventional systems. While avoiding the known health risks of these existing technologies, a properly sited geothermal heating system also boasts greatly reduced aesthetic impact and a far smaller mechanical room.

Over the past fifty years, research into a variety of geothermal heating and cooling technologies has produced systems readily tailored to the needs of any project. For existing structures, renovations, or refits in any region, there exists a range of flexible engineering solutions. Selecting the right geothermal heating system  for your project has never been easier.


Besides being green, sustainable, and renewable, geothermal heat simply costs less than any conventional system. Initial installation is certainly more expensive, but a properly-installed system gives rapid return on your investment.

The moment you turn it on, you geothermal heating system does what no conventional technology can: it begins putting money back into your pocket.

In the short term, leading estimates predict yearly returns on your installation cost of anywhere between 15 and 50 percent, depending on the size. (These numbers vary widely due to the incredible range of geothermal heating system solutions in use; the project at hand can be as small as a cottage or large as a city.) In as little as three years, your installation costs are completely recovered. No existing conventional systems can make that claim.

Once outside this initial payback period, the economic benefits of geothermal heating systems become even more immediately apparent. Yearly heating and cooling costs will be between 70 and 80 percent less than conventional systems, even when considered apart from the ever-increasing prices of oil and LP gas.


Reduced energy cost is a serious factor in the competitive advantage of geothermal heat systems; radically lower maintenance requirements is another.

Heat pumps feature far fewer moving parts than oil- or LP-based systems. Furthermore, the majority of these are located underground, unaffected by weather or everyday hazards. The simplicity and security of a geothermal heat system means you save yet more money in terms of maintenance or troubleshooting.

Conventional heating and air conditioning carries know health risks. Dirty or improperly-maintained HVAC filters are implicated in increased risk of respiratory infection, while uneven heating and cooling may aggravate existing conditions, such as arthritis and neuritis. With a geothermal system, interior temperatures are far more more consistent. The result is a far more natural, healthy feel with fewer associated risks.

In addition, the reduced aesthetic impact of geothermal heating systems is an unquestioned benefit. Whereas conventional systems require noisy HVAC blowers and competing renewable alternatives collect energy from large panel arrays or highly visible wind turbines, the bulk of a geothermal system is located underground and out of site. A small, interior mechanical room with a single pump is often enough to carry heat throughout (or out of) your structure. These pumps are often smaller than a conventional hot water heater and comparatively silent.


Originally, there were comparatively few options for geothermal heating systems in areas without access to groundwater or a saturated, permeable subsurface. Research into improved thermal response testing imagery has opened up the use of alternative thermal storage mediums for geothermal heat, with the result that this ground breaking technology is seeing wider application than any other contemporary, renewable heating and cooling solution.

If your site has ready access to groundwater, lakes, or ponds, these bodies of water can be used as energy storage mediums for your geothermal heating system at comparatively low cost. Closed heat exchange loops can be run either through shallow wells or horizontal trenches to your structure’s mechanical room, allowing use of the water as a free, natural, thermal energy storage medium.

However, greatly improved thermal response and remote sensing technologies have allowed engineers to accomplish the same objectives using carefully placed boreholes, even in the complete absence of aquifers or standing water. By analyzing the subsurface conditions of your site, a heat exchange system can be developed that exploits the available terrain for underground thermal energy storage; in essence, turning the ground under your feet into a heat battery.

No matter what the conditions of your site, there exists a geothermal heating system perfectly adapted to your needs.

This latest revolution in heating systems is cost-effective and safe to use. The heat which is absorbed from the Earth will be a wonderful option to be stored and renewed. The cost could be further reduced omitting the conventional types of boilers and furnaces by using a geothermal heating system. The clean and natural aspect of this source of heat appeals positively to all living beings alike. The growth of this technology is certain due to its high potential in any kind of harsh cold climates. The emergence of better technologies of storing the Earth’s heat will encourage more users of geothermal electric system.
