More FAQs about Geothermal Heat Pump Systems

01/03/2011

When installing a geothermal heat pump system in your existing Central Minnesota home, you may have a few concerns. Here are some common questions we have heard and their answers. During your research into geothermal heat pumps you have come up with some questions. Presented here are some additional FAQs to answer your burning questions.

Will an underground loop affect my lawn or landscaping?
While there is a short-term disruption, the piping required for a geothermal heat pump system has no long-term damaging effects on your grass, trees, and other landscaping items. Temporary bare spots created by horizontal loop systems are easily restored to its previous condition with grass seed or sod. Horizontal boring technology is also an option which minimizes lawn disturbance.

Do freezing conditions create potential problems with the buried loops?
If your geothermal loop system is installed properly, then no. Closed loop systems used by WaterFurnace geothermal heat pumps are placed at depths of a few feet. The liquid within the closed loop systems is water with a small amount of eco-friendly antifreeze, as opposed to a mixture of water and refrigerant, avoiding potential environment concerns of leakage.

Should I install an open or closed loop system?
There are many factors that influence this decision.

Open loop systems obtain heat from the temperatures stored in groundwater and is slightly more efficient. One important consideration for an open loop is the quantity and quality of the water available. Geothermal units require up to 8 gallons of water per minute with low acidity and mineral content. A proper place to discharge the water is another consideration.

Closed loop systems are generally more expensive but are virtually maintenance free. They circulate a mixture of water and alcohol-based antifreeze in a sealed environment in order to extract heat from the surrounding soil.

Geothermal Concept will guide you to the solution best suited for your specific conditions.

Can Central Minnesota residents install a ground source heat pump system themselves?
This isn't recommended. Improper installation of a geothermal heat pump can negate any benefits it can potentially provide. Issues with thermal pipe fusion, proper system design, and purging of air from loops are all better left to trained professionals.
