Geothermal heating and cooling systems have become an eco-friendly and energy-efficient alternative to traditional HVAC systems in recent years. Homeowners considering this technology may have questions about its benefits, drawbacks, and costs. In this article, we’ll address some common questions about geothermal heating and cooling systems, helping you make an informed decision.
Is Geothermal Heating and Cooling worth it?
Geothermal systems can provide significant long-term savings on energy bills due to their high efficiency. Because energy is a constant requirement, the predictable savings from a Geothermal Heating and Cooling system also provide a sound investment return. Additionally, these systems have a low environmental impact and can increase the value of residential properties as consumers become more aware of the cost savings of energy efficiency technologies. However, the initial investment can be substantial, and not all properties are suitable for geothermal installations. Evaluating your specific situation and long-term goals will help determine if geothermal heating and cooling is worthwhile.
What are the 3 disadvantages of geothermal?
1. High upfront cost: Let the cat out of the bag! Installing a geothermal system is typically more expensive than traditional HVAC systems, primarily due to the cost of drilling or excavating and installing underground loops – the infrastructure.
2. Limited availability of experienced installers: Geothermal systems require specialized knowledge for proper design and installation, and finding experienced professionals may be challenging in some areas.
3. Property requirements: Some properties may not be suitable for geothermal installations due to space constraints, soil conditions, or local regulations.
How much does it cost to put in geothermal heating and cooling?
The cost of installing a geothermal system can vary widely, depending on system size, property characteristics, and local labor rates. On average, a geothermal system installation in Ontario can range from $30,000 to $40,000 or more. There are many factors at play when considering cost of a system.

What is the downside of geothermal heating?
One downside of geothermal heating is the high initial investment, which can be a barrier for some homeowners. Additionally, geothermal systems require more land area than other systems to allow for energy infrastructure installation.
How much land do you need for geothermal?
The amount of land needed for a geothermal system depends on the type of loop configuration (horizontal or vertical) and the size of the system. Horizontal loops typically require more land area, in many cases ¾ acre or more just for the loop, while vertical loops require less space but involve drilling.
How long does a geothermal system last?
The underground loop system of a geothermal installation can last for 50 years or more, while the indoor heat pump unit typically has a 20-25 years lifespan. Regular maintenance can help prolong the life of your geothermal system. It should be noted that the 50 years lifespan is often quoted due to pipe manufacturer warranty limitations. The manufacturers need to end their warranty liability somewhere, so with Geothermal HDPE pipe; they chose 50 years!
Can geothermal heat a house in winter?
Yes, geothermal systems can efficiently heat a house in winter by extracting heat from the ground, even when outdoor temperatures are low. However, it’s important to note that any heating system must be designed to match the needs of the home it is serving. A geothermal system requires more skill in the upfront design process, as the ground loop infrastructure must also be designed to support the home. Homeowners turn to Evolved Thermal Energy for guidance on selecting the right system and contractor, ensuring that their geothermal heating system is appropriately designed and installed to meet their specific requirements.
Do geothermal pipes freeze?
Geothermal pipes are filled with an antifreeze solution, which prevents freezing even in cold conditions. The underground loop system is also installed below the frost line, where temperatures remain relatively stable throughout the year. Installers must be cautious when piping is routed at the foundation interface; the geothermal fluid will be below freezing in design conditions. If not correctly insulated at the foundation penetration, this can cause future challenges.
Does geothermal use a lot of electricity?
Geothermal systems use electricity to power the heat pump. Still, it’s crucial to understand that the primary role of the heat pump is to move energy from one place to another, i.e., from the ground into the house. Much of the energy needed for heating, cooling, and hot water is obtained for free from the earth. Homeowners are simply paying to power the heat pump to transfer this energy. As a result, geothermal systems are much more energy-efficient than traditional heating and cooling systems. For every unit of electricity a geothermal system uses, it can produce 3 to 5 units of heating or cooling energy, significantly reducing overall energy consumption.
In conclusion, geothermal heating and cooling systems offer numerous benefits, including energy efficiency, eco-friendliness, and long-term cost savings. However, the initial investment can be substantial, and the techniques require specialized skills for design and installation. By carefully considering the advantages and disadvantages and consulting with experts like Evolved Thermal Energy, homeowners can decide whether geothermal heating and cooling is the right choice for their property.
