Achieve Renewable Energy, LLC. will be exhibiting at the Home Show at Patriot Place in the Dana Farber Field House at Gillette Stadium. Com visit with us on March 21st, 22nd or 23rd. You can learn more about our residential solar lease options and special pricing on the WaterFurnace 5 Series and 7 Series geothermal equipment. We would be happy to talk about your house and recommend renewable energy solutions customized to your needs.
Achieve Renewable Energy is exhibiting at the New England Home show February 21-23 and we are giving two home show tickets to a randomly selected person who Likes us on Facebook or Follows us on LinkedIN. There is no entry form — simply Like our Facebook page or Follow us on LinkedIN before we select the winner at 3 PM on February 17th.
At the Home show we will have special offers for WaterFurnace geothermal systems and for Zero Down solar PV leases. There has never been a better time to use renewable energy in Massachusetts!
Drop by and see us at Booth #842. The New England Home Show is at the Seaport World Trade Center in Boston February 21-23. We hope to see you there!

Geothermal Heat Pump, Ground Source Heat Pump or GeoExchange — which is it?
Mankind has used the relatively constant temperature of the shallow Earth for climate control for thousands of years with structures like root cellars and caves. Energy from the Earth has been used to heat and air condition buildings using mechanical heat pumps for decades, and during that time these systems have been called many different things. Some of the most common variations include geothermal heat pump, ground source heat pump and geoexchange. So how are these different? Well, they really are not. All of these names are meant to describe essentially the same thing. The process that these names describe is the movement of heat from the ground into a building for heating and the movement of heat from a building into the ground for cooling using a heat pump.
Why not just use one name?
One name would make things simpler but that is probably not going to happen right away. What should we call the highest efficiency, lowest operating cost and most climate friendly way to heat and cool commercial buildings and residences? I think we can call it anything we want. There are people who wrinkle their noses if someone says ‘geothermal’ instead of ‘ground source heat pump’ or ‘geoexchange’ but I don’t put much weight in nose wrinkling. As a professional I believe all three names are good but imperfect.
- ‘Geothermal Heat Pump’ is the most common name but also the most maligned. On the most basic technical level it is correct because we are working with earth (geo) heat (thermal) using a heat pump. There is the potential to confuse geothermal heat pumps with high temperature geothermal energy. The biggest problem with this is when someone starts to think they need to live on the slope of a volcano to heat their building geothermally. In dealing with clients, I find that simply ‘Geothermal’ or just ‘Geo’ is the most common name for what we do in public use and this has become my most used name.
- ‘Ground Source Heat Pump’ is a technically correct option that I find second most common after ‘geothermal’. I use ‘GSHP’ nearly as often as I do ‘Geothermal’ and think it is a fine choice that helps avoid visions of volcanos. One problem is that GSHP is the common term for the equipment and does not stress the underground component as well as Geothermal does.
- ‘GeoExchange’ is my least favorite but I won’t wrinkle my nose when it is used. GeoExchange may be the most technically accurate of the three choices here. GeoExchange refers to the entire process of using the GSHP in conjunction with the underground (or underwater) heat exchanger. I think this term was coined in an effort to market geothermal heat pump technology and differentiate it from high temperature geothermal energy projects. For me, GeoEchange does not roll of the tongue and I don’t hear many clients using the term.
In truth, none of the three is a perfect naming choice. The issue will resolve itself over time. In the end, I just wish for more people to use and think about any (or all) of the names. Heating and cooling using the treasure under our feet is important to energy policy and the more it is talked about the better. Whatever name you use, you are still talking about using the heat stored in the Earth to save 60-75% of HVAC operating cost and reduce HVAC carbon footprint by the same 60-75%.
Achieve’s staff are members of the International Ground Source Heat Pump Association (IGSHPA) are are IGSHPA Accredited Installers. Achieve employs WaterFurnace factory-trained pipe fusion technicians and Factory Trained Service Technicians. Achieve is an authorized dealer for WaterFurnace Renewable Energy, Inc. In 2013, WaterFurnace celebrated its 30th anniversary of providing quality geothermal heating and cooling products.
Geothermal Heating and Cooling equals efficiency! This is particularly true with the latest and most advanced 7 Series line introduced by WaterFurnace and provided by Achieve Renewable Energy. This state of the art system is considered the ‘best of the best’ and represents the industry’s FIRST fully launched variable capacity residential unit and the ONLY unit to surpass both the 41.0 EER and 5.3 COP efficiency barriers developed by the U.S. Department of Energy.
How does it work? Unlike traditional geothermal units, which typically use one or two fixed compressor speeds, the 7 Series scales the speed up and down based on actual need. This allows the system to run more frequently at lower capacity thus resulting in an increase in efficiency that translates into over 30% savings over a typical Geo system and up to 70% savings on a more traditional fossil fuel system. The 7 Series works like a race car with a 10 speed transmission while traditional units are limited to 1 or 2.
The current market place for these variable speed or inverter-based units is just starting to develop. The only inverter-based GSHP in production that is readily available is the WaterFurnace 7 Series. Competing units from other manufacturers are anticipated in the coming year or two but are not currently available. Achieve has installed or is currently installing more WaterFurnace 7 Series units than any other WaterFurnace dealer in our area and we believe we have the most inverter-driven GSHP experience of any geothermal installer in the Commonwealth of Massachusetts.

The Massachusetts Department of Energy Resources (DOER) is also convinced. Their new $3,000,000 Financing Program for Renewable Thermal Investment specifically targets the development of renewable thermal technologies including ‘inverter driven air and ground source heat pumps.’ To learn more about this program or to further educate yourself about all of the amazing benefits of renewable energy, visit the DOER website at http://www.mass.gov/eea/.
