How Geothermal Works
Geothermal
systems are electrically powered systems that take advantage of the earth's
relatively constant ground temperature to provide heating, cooling, and hot
water for residential & commercial buildings. Rather than creating heat like
a fossil fuel system, geothermal moves heat that already exists in the
ground into your home in winter and reverses this cycle in the summer. In the
winter, the ground heat exchanger collects heat from the ground and delivers
it to the Air or Hydronic delivery system in the home. In the summer, this
cycle reverses and sends the heat from the home to the earth. Geothermal
systems consist of piping in which liquid such as water or antifreeze is the
medium. There are four types of ground loop systems to choose from:
Horizontal, Vertical, Lake, and Open. The same loop works for both heating
and cooling. However, open loop and vertical closed loop systems are
recommended in New England.
Horizontal,
Vertical and Lake systems are all closed loop systems. The heat pump and
loop form a sealed pressurized system through which the liquid medium is
circulated. Open loop systems however, are not sealed and are open on either
end to obtain the liquid medium (water), from a drilled well.
Horizontal
and Vertical closed-loop systems are laid horizontally in trenches or
vertically in wells. Both are placed in an area adjacent to the buildings
they serve. These systems can go in yards, under parking lots, or under
playing fields. Pond or lake loops require a nearby body of water with
adequate depth in which to put the loops. Open loops systems require adequate water
or depth
for the needs of the system.
We at Gagnon Heating & Air Conditioning Inc. have been installing Geothermal
Heating & Cooling Systems since year 2000. We have a geothermal project going
continuously, and have installed more geothermal heat pumps than
any of our Maine competitors. We perform design work to determine
what size geothermal
heat pump you need, as well as radiant heat and air system duct design. There are currently federal tax credits up to 30% and yearly rebates available. See our
Tax Credit Links and please call us with
additional questions.
