Happy December to everyone who supports Ground Source Energy.


As niece Kristen just said, when told our living room area was heated from the ground:
"It feels like a warm hug".


Litchfield Geothermal is currently contracted to run ten projects:

5 projects in Litchfield County,

3 in Fairfield County and 2 in New Haven County.

Our clients have been approved for over $100,000 in Clean Energy rebates.


As I start my 5th year of heating with trouble free geothermal in my own house,

I see how quickly the investment has paid off.

And how much fuel oil I have not purchased.

With winter approaching, it's 70 degrees inside versus 40F outside already.

T1 minus T2 = 70 - 40 = 30 degrees Delta T, is easily handled by geothermal.

And remember Delta T is not just a beverage served on airlines.   :)



The current energy topic that's all the rage is the ERR:

The Energy Return Ratio = Energy put into a project versus Energy out.

National Society of Professional Engineers magazine has a good article this month.

So too does World Wide Geothermal Resources magazine in the November issue.

That article was authored by me.

I was pleased to show that ground source energy projects do not use a lot of energy.

Geothermal makes good sense scientifically, whether financially subsidized or not.

My November WWGR article will be posted as soon as it gets published in a few days.


And in December look for an article on how geothermal helps builders adhere

to the new international Energy Conservation Code, adopted in Connecticut October 7.






Congratulations to all the fine folks at Gunn Memorial Library,

for the successful ground loop system we installed together.

Thank you for recognizing me in your first newsletter article below!

I also appreciate your recognition in the Antiques Show program 9/30/11.

Any attendee is entitled to a free on site consultation by presenting the Litchfield Geothermal ad.

Congratulations to everyone at Gunn Memorial Library

for heating & cooling your lovely environment with

clean, efficient, geothermal ground source energy.

It has been my pleasure to design & oversee your project.

Attendees of the 2011 Washington Antiques Show may present this ad for a free at-home consultation, to learn if converting from fuel oil to geothermal is best for them.

From one of last year's installation clients:

Hi Pete,

 Just have to tell you how great the Geo is working.

 106o outside yesterday  74o or as cold as we want it.

We are very happy.


Air conditioning season is wonderful, when you know you are rejecting heat from your house into the land you own, very inexpensively and wisely. And for next winter, with the price of fuel oil going up, past clients are delighted they invested in geothermal. And soot particulates are not being emitted up chimneys. Tropical Storm Irene had no impact to underground geothermal loops.


Special Thanks to the CT Clean Energy Fund, who has awarded Litchfield Geothermal clients over $100,000 in rebates because the systems meet performance standards. 

Rebates and tax credits help compete against fossil fuel heating subsidized indirectly with ($4 billion annual) investment tax and depreciation credits to oil and gas companies. And local jobs are created installing geo.  It's win, win, win!


Did you see magazine ?

Peter Tavino's June article on loop sizing sizing software was found on pages 3, 9 and 14.

In October is my article on Geothermal Training.

In November was my article on Energy Used to Install Geothermal.

Un December, my article is about geothermal and The International Energy Conservation Code.

Publishing and Training helps others understand Geothermal!

As a Connecticut Professional Engineering Corporation, and Accredited Geothermal Installer, here's what we do for clients



 We are proud to be approved  by the Connecticut Clean Energy Fund as a fully Eligible Contractor:


You are now approved as an eligible contractor in CCEF's geothermal rebate program.  As you know, the contractor status is not differentiated on the website but your status is now changed here at CCEF.

Thanks for your continued efforts with geothermal in CT.




Thanks to everyone helping to promote geothermal heating and cooling at the Governor's residence.

Here's our pdf  proposal.


Three sets of geothermal system homeowner rebates are available:

1. 30% federal tax credit on all geothermal costs.

2. $1200 per ton up to 6 tons for a home retrofit from CT Clean Energy Fund:

3. $500 per ton up to three tons from CL&P:

So if 3 tons can be installed for $20,000. inclusive, subtract  $6,000 from tax credit, $3,600 from CCEF and $1500 from CL&P.

  Total cost = $8,900. (pending W-9 policies, to not take a tax credit for the CCEF rebate = 30% of $3600 = $1080) =$9980.

And tax credit is not subject to the Alternative Minimum Tax.

Your electric bill will increase slightly, but you stop buying heating oil.


(My electric bill was only $230 this January to heat 2000 sf and power 4000 sf. at $0.20 per KWhr.!) $162 for a month of AC and power.




1993: The Department of Energy (DOE) and the Environmental Protection Agency (EPA) have both endorsed ground source heat pump systems as among the most energy efficient and environmentally friendly heating, cooling, and water heating systems available.

2010:  In northern Europe 3/4 of newly constructed buildings use geothermal.


Tap the resource of your property, not as easy as at right, but close!
