Choosing a Geothermal HVAC System

Geothermal HVAC System

Geothermal heat pumps are much more efficient than conventional systems. That’s because the temperature underground and underwater stays more constant than the air. Since a geothermal HVAC system conserves energy, it can lower your utility bills and help the environment by reducing emissions from fossil fuels. Geothermal heat pumps come in four different forms for homes in Severna Park, Maryland.

Horizontal Systems

Horizontal geothermal systems, also called horizontal loops, use pipes filled with water or refrigerant inside a network of trenches. They transfer heat to or away from the ground, and they’re connected to an indoor air handler. Since digging in a large area is necessary, they’re best for new construction or people who already feel like updating their landscaping.

Vertical Systems

A vertical system uses holes with pipes instead of trenches. These openings are only a few inches wide, but they’re several hundred feet deep. The pipes connect to horizontal conduits that go to the heat exchanger called manifolds. That way, a vertical heat pump won’t disturb your home’s landscaping. However, it’s more costly than a horizontal system. It could also be too difficult to install in rocky areas.

Open Loop Systems

An open loop geothermal system uses water from a nearby lake, well or pond. The water goes between the pipes and it’s source freely. If the water is drinkable, you can use this type of heat pump as a water heater too. This saves space and keeps you from needing to install, maintain or repair separate equipment.

Closed Loop Systems

Most geothermal HVAC systems have closed loops. As a result, the same liquid circulates through the pipes over and over. You’ll need a separate water heater, but you won’t have to be near a water source.
