How Efficient is Geothermal Heating?

A geothermal heat pump is the most cost-effective, energy-efficient, and comfortable way to heat your home. Geothermal technology has been around since the second half of the 20th century. But it is only in recent decades that it saw widespread adoption across the globe. In this article, we’ll look at the energy efficiency of a geothermal heating system and other advantages of acquiring one.

The Efficiency of Geothermal Heating and Cooling

Four to six feet below the ground, temperatures remain at a constant of between 40 and 750 Fahrenheit. Geothermal heat pumps can transfer the heat from the ground to condition your home’s interior and even heat water.

The efficiency of geothermal equipment is determined by the Coefficient of Performance, which is also used for air-sourced heat pumps. The COP is represented as a factor of the amount of energy the system generates versus the amount it consumes.

Geothermal heat pumps have a COP ranging from between 3 and 6. That means for every unit of energy that is taken in, it can generate more than 5 units of energy.

Why Geothermal Heating and Cooling Is Energy Efficient

A geothermal heat pump is made up of a system of loops buried in the ground and an indoor air handler unit. The underground pipes are often in the form of a closed-loop system, or they may tap into a nearby aquifer.

In winter, the temperatures are higher underground. Water is passed through the loops to absorb heat energy to distribute around the house. In summer, the underground temperatures are lower than the interior. The indoor air handler unit will draw heat from the interior and deposit it into the loops below ground.

Thanks to its efficiency, geothermal is becoming increasingly popular every year. So far, there have been more than 1 million residential installations in the United States. Every year, there are approximately 50,000 installations.

Geothermal HVAC System Efficiency Versus Photovoltaic and Heat Pump

Because they pull heat from below the ground, geothermal heat pumps do not consume a lot of energy. The system draws a small amount of electricity to power the heat exchanger, fan, and pump. They are much more dependable for interior heating than solar and air-sourced heat pumps.

In winter, the Coefficient of Performance for air sourced heat pumps is approximately between 1.7 and 2.5 COP. A geothermal sourced heat pump can still attain a COP of over 5 even on the coldest winter nights. Geothermal systems can also reliably provide hot water during the cold months.

A geothermal system can take out four times more kilowatt-hours of energy for every dollar spent on solar or wind power. The system can be designed to handle multiple heating or cooling loads simultaneously.

You can heat water, the pool, and regulate temperatures in the interior using the same system. for custom solutions that fit your needs and preferences, you can talk to Travis Crawford Heating, Cooling & Plumbing in Charlotte. To get maximum efficiency, a professional has to assess your home before installation.

Space Availability and the Viability of Geothermal HVAC

A geothermal system is 48 percent more efficient than gas furnaces and up to 75% more efficient than oil systems. Like with other heating and cooling systems, the installation of the unit can impact its longevity and efficiency.

In geothermal systems, the closed loops buried underground may be placed vertically or horizontally. A horizontal installation will inevitably take up more space. However, the installation will depend on the climatic and soil conditions, among other variables.

The air handler is housed indoors to protect it from the effects of extreme weather. If the loops are professionally installed, they can last for up to three decades. The system requires little maintenance. Maintenance tasks may include cleaning the coil and annual oil changes.

A geothermal system is quiet, energy-efficient, and comfortable to run in your home. It can handle multiple heating loads while only using small amounts of power. It is a reliable system that can last for decades.
