Can ground-source energy be installed in a house that has already been built?

Can you imagine taking advantage of the earth’s heat to warm your home?

As more people seek sustainable energy solutions, ground-source energy stands out as an efficient and environmentally friendly option.

But what if your house is already built, is it feasible to install a ground-source system?

The short answer is yes, although it does involve some challenges that you should be aware of.

However, it is totally viable and, once installed, a great benefit and savings for your home.

How does ground-source energy work in an existing house?

Ground-source energy takes advantage of the constant temperature of the subsoil to efficiently heat your home.

The installation process involves the assembly of a system of subway pipes, called boreholes or probes, which are connected to a ground-source heat pump.

This pump transfers heat from the subsoil to your home in winter and vice versa in summer, functioning as a natural AC system.

So through a ground-source system you can have the complete air conditioning of your home without the need for more systems or appliances.

Although installing this system in new construction is simpler, it is also completely feasible in an existing home.

In this case, experts first evaluate the available space and soil characteristics.

There are two main types of systems: open-loop and closed-loop systems.

The former require a water well, while the latter use a fluid circulating in a closed loop.

Therefore, depending on the space and soil conditions, one or the other will be chosen.

In addition, a vertical or horizontal system can be chosen, with vertical being the most common option in areas with limited space.

How long does it take to install ground-source energy in an existing house?

The installation time of a geothermal system can vary significantly depending on several factors.

For example: the type of system, the size of the property and the complexity of the terrain.

In general, the installation of a ground-source system in an existing home can take two to four weeks.

This includes the time required to drill and place the boreholes, as well as the installation of the heat pump and connection to the existing heating and cooling system.

During the process, adjustments may be made to the home’s duct system, which could increase installation time.

That is why it is essential to count on experienced professionals to guarantee a safe and efficient installation, minimizing the impact on daily life during the works.

Main reasons to install geothermal energy in your home

There are many reasons why ground-source is a good solution for any home, whether it is already built or not.

We are going to tell you some of the most important ones.

1. Energy Savings: Geothermal energy is one of the most efficient forms of heating and cooling. It can reduce your energy costs by up to 70%.
2. Sustainability: By using renewable energy from the earth, geothermal reduces CO₂ emissions and your home’s carbon footprint.
3. Year-Round Comfort: Unlike other heating and cooling systems, ground-source provides constant comfort year-round, keeping your home at a pleasant temperature no matter the outside weather.
4. Longevity and low-maintenance: Geothermal systems are designed to last. Ground-source heat pumps typically have a lifespan of 20 to 25 years, while underground loops can last more than 50 years. Additionally, they require little maintenance, which lowers additional costs.
5. Incentives and Grants: Many regional governments have already approved grants for these types of projects. Increasingly, more incentives are being offered for the installation of renewable energy, including geothermal. This can help significantly reduce the initial installation cost, making the investment more accessible.
