Geothermal Heat Pump Questions Concerning your Home
Will my existing ductwork function with my new geothermal system?

Yes, in most cases. Hoffmann Brothers will be able to determine ductwork requirements and if any minor modifications are needed.
Will an underground loop affect my lawn or landscape?

No. Research has shown that loops have no adverse effects on grass, trees, or shrubs. Most horizontal geothermal installations require trenches about six inches wide. Temporary bare areas can be restored with grass seed or sod. Vertical geothermal loops require little space and do not damage lawns significantly.
 
I have a pond near my home. Can I put a geothermal energy loop in it?
 
Yes, it is recommended that the pond contain a minimum of eight feet of dept at its lowest level during the year and have ¼ of an acre of surface area.
My yard contains many shade trees. Will this affect ground temperature and my ability to use it as an energy source?

Not at all, the geothermal system is installed deep enough that it utilizes constant ground temperature.
 
Can I put the loop under my septic system?
 
This practice is discouraged. The geothermal earth loop may drop below freezing in the winter and could damage your septic system.
 
If the geothermal loop falls below freezing, will it hurt the system?
 
No, the antifreeze solution in the loop will prevent freezing down to approximately 15 degrees F. Hoffmann Brothers uses Environol or methanol as the antifreeze.

Can a geothermal heat pump system be added to my fossil fuel furnace?

Yes. Called dual systems, they can easily be added to existing furnaces for those wishing to have a dual-fuel heating system. Dual-fuel systems use the geothermal heat pump system as the main heating source, and a fossil fuel furnace as a supplement in extremely cold weather should additional heat be needed.

Will I have to add insulation to my home if I install a geothermal system?


Geothermal systems will reduce your heating and cooling costs regardless of how well your home is insulated. However, insulating and weatherizing are key factors in gaining the maximum amount of savings from any type of heating and cooling system.
 
How does a geothermal heat pump also heat water for my house?
 
Using what is called a desuperheater, geothermal heat pumps can save you up to 75 percent of your water-heating bill by pre-heating the water. When the geothermal system is operating, it pulls water from the water heater and circulates it through a heat exchanger and returns the warmed water back to the tank. Some geothermal models can provide all of your hot water needs on demand at the same high efficiencies of the forced air models.
