Geothermal Systems and Radiant Heat

Geothermal Systems and Radiant Heat

Is radiant floor heating right for your home? With a geothermal system, it can be an efficient solution.

In the winter, people are always looking for better ways to stay warm and comfortable in their homes. They are also seeking ways to save more on heating bills. Geothermal systems paired with radiant heating is perhaps your best answer. It is an eco-friendly and quiet means of both providing luxurious warmth and saving more than you may have imagined.

What Is a Geothermal System?

A geothermal system uses the constant heat from the earth to both heat and cool a home. The earth is always at a temperature of 50 to 60 degrees Fahrenheit, and a geothermal heat pump can transfer that heat into a house. Alternatively, it can take the excess heat in a home and sink it back into the earth. Geothermal systems use a closed or open ground loop system filled with fluid to connect the heat in the ground to the home’s heat pump, which conducts warmed air throughout the ductwork. In Maryland, the groundwater quality is poor, which is why Ground Loop recommends a closed-loop system. 

The three main advantages of residential geothermal systems are efficiency, affordability, and comfort. Using the constant temperature of the earth, geothermal heat pumps do not need to exert extra energy to maintain desired air temperatures like forced air systems might. Over time, geothermal systems have become more efficient than ever, and thus more cost-effective. Geothermal heating has become more accessible to homeowners and provides quiet and sufficient heating to your home.

What Is Radiant Floor Heating?

Radiant heating offers a way to deliver warmth directly to you via your home’s walls and floors. Radiant heated floors are growing in popularity for the beautiful warmth that they give. There are two main types of warm floor heating systems, electric, and hydronic.  Hydronic radiant is running pex tubing in the floor and circulating hot water through the tubing. Electric radiant is electric mats laid under the flooring. Ground Loop recommends electric floors for small square footage areas, such as a single bathroom. If you decide to do radiant in larger areas, such as the whole 1st floor or the whole house, then hydronic radiant makes the most sense. Hydronic or hot water radiant is much more efficient than straight electric floors. The downside to hydronic radiant heating is the tubing is most efficient when installed over the existing subfloor and underneath finished floor covering. This is much easier to do during a remodel or new construction application, or when replacing existing flooring. 

Advantages of radiant floor heating include a quiet system that does not disturb allergens like a forced-air system might, greater efficiency and lower heating bills. A hydronic floor heating system powered by a geothermal heat pump is one of the best ways to save and keep warm for many winters to come.
