In a day and age where saving money and helping the environment are simultaneously important, homeowners everywhere are turning to alternative heating work systems to achieve both—and geothermal heating is a commonly chosen route.


While you may know that geo refers to earth and thermal refers to heat, you might still find yourself perplexed at such a system’s finer workings. How, for example, is it possible for your home to be heated when the ground is frozen outside?


P&D Mechanical, your Robbinsdale plumbing work and heating work experts, is here to answer all your questions about this revolutionary technology below.

How Does Geothermal Heating Work?

You’d be correct to assume it uses heat from the ground, but it’s a bit more complex than that. For one, the heat which the device uses is consistent, even when it’s cold outside—the necessary pipes are buried deep enough underground to be unaffected.


According to the EPA, geothermal heating works like this: A device called a heat pump pushes liquid through these connected pipes; the liquid picks up the heat from the ground and returns to the pump, which proceeds to use it to warm your home. There are slight variations of this process depending on location and what temperatures must be reached.


The aforementioned liquid can be one of two things: ground water or water mixed with other environmentally safe products that help to carry the heat. Depending on the contents, your geothermal heating’s water piping can be of an either “open-loop” or “closed-loop” variety.

Why Is Geothermal Heating Environmentally Sound?

Simple: it takes advantage of renewable energy that the Earth naturally makes! No need to rely on fossil fuels or electricity; your heat will come straight from the planet’s crust itself. It even beats out other renewable resources—IE, wind—in terms of reliability, as it’s constantly available independently of the weather, meaning you hardly ever will have to resort to other, potentially more damaging energy sources.

How Does Geothermal Energy Save you Money?

Say goodbye to buying fossil fuels or excessive electricity use—you’ve got free energy sitting right in your backyard! These machines also are extremely efficient because they don’t heat air, they just move it around, which takes far less energy. Finally, you’ll also save on maintenance costs, because the machine is never exposed directly to harsh weather.
