Geothermal heat pumps, also known as ground-source heat pumps, are sweeping the nation as a source of efficient, eco-friendly heating and cooling. These pumps work by exchanging heat between the home and the ground a few feet beneath the surface. They're incredibly efficient, require little maintenance, and work well even in areas where the outdoor temperature fluctuates wildly. The following numbers help illustrate just how amazing geothermal heat pumps really are as a heating and cooling solution:
1940s: When geothermal heat pumps first came into use.
Many people are hesitant to consider geothermal heat pumps for their homes because they mistakenly believe that these pumps are a new technology, and therefore they may not be all that reliable, or may cause some problems that are not yet known. While geothermal heat pumps are becoming more popular recently due to a push for greener, more energy-efficient HVAC solutions, they are far from new. Engineers and HVAC specialists have had decades to work the kinks out of geothermal pumps systems, and the best practices for installing and utilizing them have been well established.
80%: The percent you could save on your heating and cooling bill by installing a geothermal heat pump.
Geothermal heat pumps don't have to work as hard as standard heating systems. They essentially "collect" heat from below ground rather than generating it directly from a fuel source like oil or gas. In the summer, they "collect" heat from the home and deposit it below ground, rather than using a lot of fuel to air condition your home. Really, the only energy a geothermal pump system uses is that required to move the water through the system.
Though 80% is a good estimate, the actual amount you save will depend on the size of your home, the climate in your area, how well sealed your home is, and various other factors. This online calculator can give you a more precise estimate of your projected cost savings when switching to a geothermal heat pump.
1,000,000: The approximate number of geothermal heat pumps used in U.S. buildings.
As you can see from this number, heat pumps are now pretty common. In fact, about 50,000 new heat pumps are installed in residences each year. For this reason, it is becoming increasingly easy to find an HVAC specialist who works with heat pumps. It's very important that a heat pump system is installed properly in order for it to work effectively and efficiently, so you should only have your system installed by someone with plenty of experience -- finding one of these technicians is becoming quite easy.
50: The number of years the ground loop portion of the system is expected to last.
You'd be hard pressed to find any other type of heating system that's expected to last for 50 years or more! Though the mechanical parts of the pump are expected to last only 25 years, they are rather easy to replace. The below-ground pipe section, which is more difficult to access once installed, is very durable and unlikely to need repairs or replacement for as long as you live in the home.
300 - 600%: The estimated efficiency of a geothermal heat pump on the coldest winter nights.
Regular furnaces are often 80 - 98.5% efficient. That means that for every 100 units of energy that are put in, 80 - 98.5 units of energy are actually released to heat the home. Conversely, for a geothermal heat pump, for every 100 units of energy you put into a geothermal heat pump, 300 - 600 units are released into the home. This is possible because the energy that is input is used to collect additional heat energy from the ground. This remarkably high efficiency is why heat pumps are so inexpensive to operate.
If you're looking for a low-maintenance, long-lasting, extremely efficient heating solution, make sure you give geothermal heat pumps some consideration. They have a long history of success, and people are really beginning to catch on to how awesome they really are. Will you be one of the 50,000 people who install heat pumps next year?Share

My name is Brandon McCauley and this blog is about new trends in the construction industry. In this blog you'll learn about new types of materials that are long-lasting and durable. You'll also find out how new homes and businesses are being built to be more energy efficient. I continually study new trends and the latest developments in construction because this is an interest of mine. I'm always amazed when I see new building and home designs that are out of the ordinary. If you also like learning about new construction trends, I think you'll find my blog very interesting and informative.
