From Angie's List: |
My wife and I wanted to learn more about what type of geothermal heating
system would be right for our home. We were seeking an unbiased source to
contrast the recommendations made by the HVAC companies who were seeking our
business. I came across Mr. Tavino’s name and contacted him via email. He
was immediately responsive. Within literally one day, he was at our house,
giving us sage advice. He is a professional engineer with vast knowledge of
geothermal systems. Mr. Tavino’s counsel guided us in making a decision that
we felt comfortable with. Mr. Tavino generously offered to continue to
answer questions after his consultation, which he has done without
hesitation. Considering the enormity of the investment, the small amount
that we paid for his consult was money well spent. I believe that Mr. Tavino can provide different types of consultation, depending on your needs. We just wanted to get a rough idea of what he thought of some of the geothermal proposals based on his visual inspection and some limited measurements of our house. He reviewed numerous geothermal proposals and energy efficiency test reports. |
You are urged to begin with a paid two hour on site consultation,
reviewing all aspects of ground source energy options for your building.
Sample Date of 2014 and 2015 List discontinued during lack of tax credit. 2 hour Consultations (Many follow up for more design and installation. All are satisfied) |

Litchfield Geothermal is the web site run by Peter J. Tavino Jr. PE PC (Professional Engineer, Professional Corporation) (PE PC) A Connecticut Corporation since 1986. |
This web site allows everyone interested in knowing about ground source heat to see pictures of all aspects of it, with complete explanation of the geo process at no charge. The main scope of work for clients is designing their closed loop geothermal project to comply with the Federal Tax Credit requirements and often Northeast Utility rebate requirements. Having a system approved by all these entities assures the client of efficient geothermal heat pump operation. All conforming systems have outdoor ground exchange loops separate from indoor heat pumps and ducts. Peter J. Tavino Jr. PE PC provides engineering service, (which is usually reserved for big commercial projects) to homeowners who need only one or two heat pumps. Just as a Professional Engineer designs a new septic system, a PE designs the geo system. All work is to professional engineering standards. The usual initial 2 hour on site consultation fee varies from $300 depending on your location, within Connecticut or not, and including Peter's extra time and travel expense. The homeowner is invited to ask all questions about options, insulation, cost estimates, etc. After the paid in depth 2 hour consultation that includes cost estimates, Peter Tavino can offer a no cost bid to have the required outdoor system installed. If we install the outdoor system, the consultation fee is deducted from that cost. Indoor quotes by contractors are also available. Or bids may be solicited like in the commercial application described below. Service includes the following: Study the existing building floor plans and determine heating and cooling BTU per hour loads for each zone. A heating and cooling analysis can also be performed for a nominal fee. With owner input, select a heat pump size usually to meet the cold weather needs. Examine site, soil and bedrock types for possible 7' deep horizontal trench, or vertically drilled boreholes. Prepare a site plan for horizontal, or borehole depths. If a horizontal loop is installed under ideal conditions, Peter Tavino provides field labor, heat fusion and supervision for that. If vertical bore, Peter helps inspect the grouting operation and cuttings runoff control, etc. Residential new home or retrofit quotes include heat pump warranties and satisfaction. For larger commercial engineering and out of state projects, (based on past client requests for Professional Engineering assistance with qualified contractor selection), as the owner's consultant, Peter helps them select contractors. Usually a Request For Proposal (RFP) is written and sent out to contractors with no business affiliation with Litchfield Geothermal, except we usually have worked together in the past, and they come recommended. They often thank Peter for the lead, but there is never any improper financial commission, payment, return of favor, etc. Peter promotes problem free installations this way. Modest hourly billing applies as work progresses. All past clients have been very satisfied with Peter Tavino's attention to their project, and offer to be contacted for reference. See some sample comments below. I look forward to working on your ground source energy project next. |
Here's how we answered the recent Connecticut Geothermal Association company questionnaire
The system is working superbly. Coldest we have had has been 30o but it was fine. Very quiet, very comfortable. No need for humidification either. I mailed your check this morning. Thanks again for a job well done. Ken
Celebrations Development and Contracting thanks you Peter for working with us to secure the Connecticut Clean Energy Fund and CL&P rebates. Bill
Yes, Peter, you can use me as a reference. Tyler
Pete,
WaterFurnace in and operating. Still needs some adjusting, VIP, and some
parts added to the ducts. This to be done on Thursday. Until then, I
will be detailing any additional bugs that need correcting.
Thought that you might like the pictures.

Pete,... System has been working great.... Thanks, Marc
Dear Peter,
Hi Pete;
Neil sent us the check last week. Thank you.
Thank you, and great job you've done. Tracy

SITE PLAN ENGINEERING EXAMPLES
Here is an 18 borehole plan for 2013, part of a detailed AutoCAD drawing, and balanced without valves:
This is the 730LF smooth loop design for Peter's house as installed in 2008: See how it performs years later at www.GroundEnergySupport.com
Here are two plans for projects installed in summer, 2010.
Detail used in 2009.
In this 2008 design, in New York State, twin 1 1/2" geo pipes that are easier to uncoil are specified.
And another New York design avoiding the existing septic system.
This site in southern Bridgewater, CT has capacity for 48,000 BTU.
For this new house construction, one of two loops is placed between the septic system and a detention pond.
Pond is not part of property. If it were, a pond loop would have been specified pending Wetlands approval.
Here is Lot 1 design but not yet built in the southern USA where cooling is required. No ledge to worry about, but groundwater is critical:
To be installed April 2013.
To be installed April 2013.
