Consider Installing a Geothermal System This Winter

Monday, January 11th, 2016

There are a myriad of different heating options available on the market. While many homeowners are content to install a system just like the one they had previously, you should consider the benefits of other options. Geothermal systems, for example, have many advantages that other heating systems do not possess. Read on for more information about geothermal systems, and how you can benefit from installing one in your home.

How Geothermal Heating Works

Monday, January 27th, 2014

If you walk outside on a cold day and stand on a bare patch of ground, you may wonder how you could extract heat from it use it to warm your house. However, geothermal heat pumps work with incredible efficiency that you won’t find in many other heating systems. Where standard heat pumps, which use the air as their source for heat exchange,  lose efficiency in very cold weather, geothermal heat pumps do not encounter the same problem because the temperature under the earth stays the same year round.

We’ll explain the operation of geothermal heating (which also applies to cooling) so you’ll understand some of its benefits. Call SPS Mechanical Inc. for more information, and to set up an appointment to see if a geothermal heat pump will work where you live.

Geothermal Heat

The earth itself is a source of heat: the core radiates warmth out toward the planet’s surface, and the continental plates float around on a molten sea. Although you can’t sense this from just walking around on the surface, you will notice it if you dig down only 10 feet. At this point, the temperature stabilizes to around fifty degrees, and does not fluctuate much, regardless of the chill of the air above. A geothermal system exploits this temperature stability and uses it as the medium for the heat exchange in its heat pump.

Underground pipes, called loop fields, are buried down in the earth near a home. Vertical loops will be buried deep, but horizontal loop systems won’t require as much digging to install. Antifreeze flows through these loops, and it absorbs heat from the earth.  The heat is than transferred to your heat pump system via a heat exchanger, and the heat pump uses that heat to warm the air that is then distributed throughout your ducts. (During the summer, the process reverses, and heat is removed from the home and put into the ground.)

Air-source heat pumps lose efficiency when the temperature drops below freezing, but geothermal heat pumps won’t have this problem because the ground provides a consistent temperature (usually around 55°F) . The geothermal pump also operates almost silently and works so efficiently that it can usually pay for itself with energy savings in 5–10 years. Geothermal heating is also beneficial to the environment, with almost zero emissions.

Professional Geothermal Installation

Only professional geothermal installers can correctly perform the job of setting up a system for you. Installers can also determine if geothermal will work for your location, since not every home is ideally situated for this type of heating.

Benefits of Using Geothermal Heating

Monday, January 20th, 2014

Geothermal heating isn’t a new development; Iceland has heated homes for hundreds of years using the heat from volcanic fissures on the island. However, it is only recently that homeowners in the U.S. have started to take advantage of advances in technology that bring the heat from the earth itself right into their living rooms.

Geothermal heating uses coils buried in the ground around a home to transport the earth’s stable heat to an indoor air handler. Essentially, a geothermal system is a heat pump that uses the ground instead of the air as its medium for exchange (i.e. a “ground-source heat pump” as opposed to an “air-source heat pump”). They offer some substantial benefits to homeowners. If you are interested in geothermal heating in Haddonfield, NJ, contact SPS Mechanical Inc. today and speak to one of our specialists.

Some geothermal benefits

  • Stable heating: Air-source heat pumps have trouble extracting heat from below-freezing outdoor air—something that happens often in New Jersey. But below the earth’s surface, it maintains a steady temperature of around 55°F, so a geothermal system encounters little trouble providing sufficient heat no matter how cold it gets outside.
  • Energy efficiency: Although some homeowners shy away from the initial cost of installing a geothermal system, they often pay for themselves over time—and will last a very long time. Geothermal systems only use a small amount of electricity to extract heat from the ground, and can return six times the amount of energy they use in heating power. This can mean large savings from your energy bills.
  • Clean energy: If you are interested in heating that doesn’t damage the environment, then geothermal is one of your top options, since it creates almost no emissions.
  • Quiet operation: Most of the activity in a geothermal heat pump occurs underground, so you will have little in the way of noise pollution to deal with.
  • Safety: Since geothermal power does not require the burning of any fuel or create any emissions, they are among the safest options for heating.

Professional installation is key!

Geothermal systems require an elaborate installation process that places the coils down into the ground. This work requires specialists—and you should have them involved in the process from the beginning, since they will also be able to identify if your home will benefit from geothermal heating. (It isn’t suitable for every location.)

Choosing to go geothermal is a big step, but SPS Mechanical Inc. is available to make it as pain-free as possible. We’ll also make sure your installation is done correctly so you will enjoy all the advantages of the technology. Contact us today to get started.
