Ask The Experts: Geothermal Heating Expert

Posted By on September 9, 2010

In this “Ask the Experts” blog series, we have asked industry experts help explain all sorts of housing related topics. Today, David Spaeth, a geothermal heating & cooling expert, explains what you need to know about geothermal systems.

1. How have geothermal heating & cooling systems changed in the last 3 years?
The equipment itself has not changed but different combinations of equipment and loops has evolved as heating contractors have learned more efficient and cost effective ways to install the system in a price competitive market.

2. How many installations will you do on newly constructed single family homes this year? How does this compare to previous years?
We will install approximately 900 single family systems for newly constructed homes.  This is about 35% less than in years previous to 2008.  2008 and 2009 were about 700 and 800 respectively.

3. How many retrofit installations will you do on existing homes this year? How does this compare to previous years?
We will put in about 100 retrofit systems in single family homes and another 180 for multifamily retrofits for contractors.  The single family number is up 20% from last year and the multifamily number is about the same

4. How much does a geothermal system cost?
It depends on the size of the home.  Excluding drilling, they typically cost anywhere from $10,000 to $20,000.  Drilling can run anywhere from $1200 to $2000 per loop with an average of one loop per ton of cooling.

5. Why would I as a homeowner spend my money to install a geothermal heat pump instead of, for instance, solar panels?
It is the most efficient way to heat and cool your home and has the largest impact on your energy bills per dollar invested. Additionally, goethermal units qualify for a 30% Federal Tax Credit.

6. Anything else you would like to note?
It is absolutely vital that homeowners educate themselves on geothermal.  The lowest price is not always the right choice.  Many contractors take shortcuts to win the bids such as not grouting their loops.  There is a multitude of problems that this can cause with the least of which being an inefficient system.

7. Please provide your contact info for interested persons, including your website address.
