Can a ground-source heat pump system provide 100% of my home's heating and cooling needs?
Yes. Properly sized ground-source GeoThermal GSHP systems can provide 100% of your heating and cooling requirements and at the same time provide domestic hot water. Outside temperatures do not affect GeoThermal GSHP systems. Both hydronic as well as with forced air system delivery is available for new or existing structures.
Are all GSHP systems alike?
No. Each application requires a different GeoThermal GSHP system designs. Most systems provide both heating and cooling. Some systems provide heating, cooling, and hot water. There is no one system that works for every application..
What size system will my home or business require?
Oversized and undersized GeoThermal GSHP systems provide for many problems. An ACCA Manual J heat load calculations should be completed on your home to provide the specific information required to properly size the entire system and give you the most efficient cost effective system to meet your specific needs.
How much space does a GSHP unit require?
Most of the GeoThermal GSHP system, the ground loop, is installed underground. The interior units require the same size footprint of a traditional furnace.
How long do ground-source heat pump systems last and do they carry a good warranty?
A GeoThermal GSHP systems is highly reliable. With only 3 moving parts, service life of the unit is 25+ years under normal use. Many manufacturers offer a 10 year coverage on major parts. The manufacturers of the polyethylene earth loop, used for for the underground heat energy transfer, warrant their product for 50 years. Independent tests show a useful life-span of over 200 years.
Will I have to add insulation or upgrade my windows if I install a GSHP system?
GeoThermal GSHP systems will reduce your heating and cooling costs regardless of how well your home or building is insulated. Research shows that for every $1 spent in building envelope energy efficiency upgrades, $3 is saved in your GeoThermal GSHP systems installation cost. Combining geothermal technology with other energy efficiency measures will maximize your monthly savings and lower your total system installation costs.
Do I need to increase the size of my electrical service?
GeoThermal GSHP systems, as a rule, don’t use large amounts electricity so your existing service should be more than adequate.
Will an underground "earth loop" affect my lawn or landscape?
No. Industry research has shown that GeoThermal earth loops have no adverse effects on grass, trees, or shrubs. Vertical or horizontal earth loops require little space, do not damage lawns significantly, and can be installed in all types of soil varying from sand to hard granite.
Do I need separate "earth loops" for heating and cooling?
No. The same loop works for both. During the cold season the heat is extracted from the ground. In the warm season the heat is transferred back into the ground.
