My husband and I looked into a variety of types of heating and cooling systems for our new home.
Energy efficiency and environmental impact were very important to us.
Along with keeping a comfortable home, we hoped to minimize our monthly costs and carbon footprint. The Environmental Protection Agency lists geothermal heat pumps as the most environmentally friendly means of residential temperature control. This type of heating and cooling maintains ideal year round comfort in the average home for around a dollar per day. The system actually generates four times the amount of energy it requires to operate. This is because a geothermal heat pump pulls energy out of the ground. It takes advantage of the free and renewable energy provided by the sun. Despite fluctuating weather throughout the year, the underground temperature remains relatively stable. This allows the system to pull heat out of the ground in the winter, compress it to a higher temperature and pump it indoors. During the summer, the heat pump draws heat out of the indoor environment and deposits it into the ground, creating a cooling effect. The heat pump runs on a small amount of electricity, burning no fossil fuels and creating no combustion byproducts. Because of this, there’s no greenhouse gas emissions, fumes or fear or fire. The heat pump keeps a cleaner, safer and healthier indoor living space. It doesn’t overly dry out the air in winter and helps with dehumidification in the summer. Plus, modern geothermal heat pumps effectively filter contaminants out of the air. Although geothermal heat pumps are super expensive to install, they typically pay for themselves in energy savings in under five years.
