What Is Geothermal Energy and How Does Geothermal Heating Work?

If large companies can spend thousands of dollars on renewable energy sources that save them millions on electricity each year, why can’t you spend hundreds of dollars on the same thing in order to save you thousands? But before you go out and get yourself a geothermal heating system, take some time to learn about it first.

One of the best things about geothermal energy is its name because it pretty much explains what it is and where it comes from. From the “geo” part, you can see that this energy comes from inside the earth. The “thermal” portion of the word means heat. Put them together and you’ve got a heat energy source that comes from the earth.

How do you Get it?

In a nutshell, it comes from the magma underneath the earth’s crust. But you don’t necessarily have to farm magma. What you want is the heat that comes from it.

All that molten earth deep inside the crust doesn’t just circulate the planet and help maintain our magnetic fields. This substance also melts radioactive uranium and potassium, causing these materials to release even more heat upwards.

Geothermal Energy With that being said, temperatures a little below the ground can go to as high as 50 F. And that’s only within 10 feet of the crust. Imagine how much hotter it would be if you went deeper.

When this temperature is used through various geothermal technologies available today, you’re looking at an energy source that’s more potent that oil and other bio-gasses put together!

As of today, many countries are now tapping into this resource and are using the heat within the earth to power their machines. Usually, places with plenty of active volcanoes have very healthy amounts of usable heat due to the magma being closer to the crust on account of the volcanoes. This is why places around the “Pacific Ring of Fire” are some of the best sources of this energy because of their abundance of volcanoes.

Is Geothermal Energy Renewable or Nonrenewable

That’s one of the first things you want to ask. Are you using up something that you can’t get back just like oil and other fossil fuels? To determine if a source is renewable or not, it has to meet to answer several question:

  1. Does nature provide this form of energy?
  2. Does this energy run out?
  3. Does nature naturally replenish this source?

As mentioned earlier, this heat comes directly from the abundance of molten rock underneath the earth. So the answer to the first question is yes. And as long as there is rock to melt and our core remains intact, we will always have this form of energy available to us. So the answer to the second question is yes as well. And because we don’t need to melt the rocks ourselves, the answer to the last question is another yes.

In essence, Geothermal energy is a clean and renewable source that we don’t have to worry about using up. It’s here to stay as long as our planet still has its core. And now that you’re ready to learn how to use it, the next thing you want to know is how a geothermal heat pump works.

What is a Geothermal Heat Pump and How do They Work?

In order to harness geothermal energy, you need a means to reach deep into the earth and use the temperatures to give you energy. This is what a Geothermal Heat Pump does.

Geothermal Heat PumpThis is a system that is composed of pipes that run inside your home then into the ground at a specific depth, where the temperature is constant regardless of the season.

Water treated with an anti-freezing solution is circulated through these pipes to transfer heat from the earth to your home or from your home to the earth depending on what’s needed.

When it’s hot, your geothermal heat pump will take the heat from the air in your home and circulate it into the ground where it heats the earth instead of your living room.

During colder periods, the pump will take the constant high temperature underneath the earth and circulate that steamy temperature into your rooms where you need it. These pumps also work with your water system to provide you with a good source of hot water all the time.

And because it uses the natural heat from the earth, you won’t have to burn any fossil fuels or spend on expensive air conditioning systems that cost a fortune to maintain. That’s why it’s sometimes called a Geoexchange system.

Is a Geoexchange System Right for My Home Heating and Cooling?

The answer to that question is a resounding yes. You’re only investing in a pipe and pump system; nothing too fancy. It’s convenient and non-intrusive and will cut down on your utility by more than 75%. That means you spend 3/4ths less on electricity and power with a Geoxchange system that with any other home heating or cooling system.

Choosing the Right Ground Heat Exchanger

Now that you’re ready to enjoy the benefits of geothermal energy, it’s time to look at the qualities you need in a good system. Here’s what you want:

  1. Pick one with a sturdy piping system that lasts as long as an underground bunker. You don’t want to have engineers digging up those pipes for repair every month.
  2. Pick one that’s government-certified to decrease your utility costs. These claims can be verified and proven if you dig well enough.
  3. Finally, choose a provider that matches a heater to your home set-up. Find ones that can install vertical loops if you have less space. A good heat exchange system can also use open-systems that connect directly into small lakes and ponds near your house if there are any.

There are many of these on the market right now because of how well they cut down on your expenses. At the end of the day, it’s all about a matter of choosing a clean and renewable source of power to help maintain your home.
