Going Geothermal in the Granite State
listen:
  It’s one of the lesser-known and understood forms of Alternative Energy…but it’s getting some serious attention recently…both in the U.S. Congress and the New Hamsphire Legislature. We’ll find out how geo-thermal works…and what it’s potential might be. Guests

There is a new home open house on Creekwater road in Loudon tomorrow see http://www.zetlandparade.com/
Thanks,

40 degree well water is lot of heat to a refrigerant that boils at minus 20
Thanks,

I fear your guest are painting too pretty a picture about the green house effect. I think geo thermo is better than oil or electric heat, but only by a factor of 3. You need power to run the heat pump, my understanding is the coeficent of performance for these systems is 3, so its 60% better for the environment.
Think I'm too late to get this aired, but they distorted the reality.

My husband and I are currently building our first house. We got a quote for geothermal heat and it is much more expensive than regular heat. How much money would we be getting back if we went with geothermal?
What about State incentives for geothermal? Do they exist? Do your visitors think that the State should be doing more to encourage these investments?
The show focused more on large grid/industrial applications. I wonder what the cost is for residential use? How far into the ground is the drilling for residential use? And are there companies in NH that do this?
Hi All
We are the builders of the 21st Century Victorian Demonstration Green Home that Mike refers to. The home is open to the public to look at (including the geothermal system) through December 2. See www.zetlandparade.com for list of events. Is designed to be the second LEED certified green home in all of NH.
We are using a "standing column" geothermal system meaning that it uses the well we had to drill anyway for the domestic water. Our estimated yearly cost for heat, central air and domestic hot water is $1200 to $1300 for a 2280 square foot home (granted we have an Energy Star 5* plus insulation package which is what you want for geothermal). The electric heat pump actually converts 1 part electric power to 5 parts heat so it is super efficient with no harmful CFCs in the air conditioning part. Granted it uses some extra electric but NO OIL OR GAS at all which costs money to bring here and makes us dependent on the most unstable part of the world.
The geothermal system ended up costing us LESS than a conventional high grade oil or gas system as we got a great yield on the well and PSNH allows up to a $7500 rebate based on square footage which pays for the geothermal heat pump itself.
