Geothermal Energy: The Heat Pump Solution

Part 5 of Geothermal Energy: Power from the Depths of the Earth. The geothermal heat pump doesn’t create electricity—but it greatly reduces consumption of it. If you would like to reduce the cost of heating and cooling your home, you might want to consider installing a geothermal heat pump, an economical and energy-efficient technology for […]

Overview: Geothermal Heat Pumps

Part 1 of Geothermal Heat Pumps. If you’re planning to build a new house, office building, or school, or replace your heating and cooling system, you may want to consider a geothermal heat pump (GHP) system. GHP systems are also known as GeoExchange, ground-source, or water-source heat pumps (as opposed to air-source heat pumps). Regardless […]

Selecting a Heat Pump

Part 3 of Air-Source Heat Pumps. When selecting an air-source heat pump, consider the following three characteristics carefully: the energy efficiency rating, sizing, and the system’s components. Energy efficiency rating In the United States, we rate a heat pump’s energy efficiency by how many British thermal units (Btu) of heat it moves for each watt-hour […]

Heating and Cooling Systems

Part 4 of Elements of an Energy-Efficient House. Specifying the correct sizes for heating and cooling systems in airtight, energy-efficient homes can be tricky. Rule-of-thumb sizing is often inaccurate, resulting in wasteful operation. Conscientious builders and heating, ventilation, and air-conditioning contractors size heating and cooling equipment based on careful consideration of the thermal envelope characteristics. […]
