Building Green: Geothermal Heating & Cooling

Geothermal heating & cooling system at Mancusi Builders' environmentally-friendly green house in Sandown, New Hampshire!

The Benefits Of A Geothermal Energy System
  • Use 25%-50% less electricity than conventional heating or cooling systems.
  • One system provides both heating and cooling.
  • The piping is specially designed to withstand extreme temperatures.
  • The loops are joined by thermal fusion (melting them together), so there are no leaky fittings.
  • There are no noisy "on" cycles with blasts of hot or cold air.
  • No fluctuations in temperature from room to room as each room has its own feed and return.
  • No flues to get clogged.
  • No dangers of carbon monoxide poisoning.
  • No noisy outdoor air conditioner.

A Geothermal House That Costs Just $600-$800 A Year To Heat & Cool

This energy efficient home uses no fossil fuels to heat or cool with, just a state-of-the-art Geothermal heating & cooling system that will reduce your energy costs by as much as 75%.

No Oil Deliveries, No Gas, No Fossil Fuels At All.

How A Geothermal Energy System Works
A geothermal system, also called a standing column system, is an eco-friendly heating and cooling process. It works on a simple premise: the earth below a certain depth (the frost line, usually about four feet deep), is a constant temperature of about 50 degrees throughout the year. The system draws water out of a well and runs it through a heat exchanger, similar to the heat pump on a refrigerator. The water is heated and that heat is transferred to the air in the house during the winter. The water rotates through the system and is returned to the well. To cool the home in the summer months, the system simply works in reverse.

Geothermal Energy System Components
A geothermal heat pump system consists of pipes buried in the shallow ground near the building, a heat exchanger, and ductwork into the building. The Geothermal hot water system includes a hot water tank and a warm water tank which are heated independently of each other by a close loop system. The geothermal hot water system uses the least amount of energy possible in heating the water in both tanks.

Environmentally Clean & Cost Effective
According to the U.S. Environmental Protection Agency, geothermal heat pumps are the most energy-efficient, environmentally clean, and cost-effective systems for temperature control.

Reduces Energy Consumption & Corresponding Emissions
According to the EPA, geothermal heat pumps can reduce energy consumption - and corresponding emissions - up to 44% compared to air-source heat pumps and up to 72% compared to electric resistance heating with standard air-conditioning equipment.
