Heating bills across the country are the highest they have ever been, without any relief in sight. Even if your older furnace runs, from an economic standpoint it would be wise to replace it. With the proper furnace selection, your central air-conditioning bills can be lower too. Compared with a 17-year-old furnace, a new furnace…

How heat pumps achieve energy savings and CO2 emissions reduction Heat pumps and energy saving This section gives a brief introduction to heat pumps. Based on six basic facts about heat supply the value of heat pumps is discussed. It is argued that heat pumps are very energy efficient, and therefore environmentally benign. An efficient…

Several relatively innovations are improving the performance of heat pumps. Unlike standard compressors that can only operate at full capacity, two-speed compressors allow heat pumps to operate close to the heating or cooling capacity that is needed at any particular moment. This saves large amounts of electrical energy and reduces compressor wear. Two-speed heat pumps…

You can read your own meters to help monitor your electric or gas energy use. During the heating season, your energy use should be compared to the number of heating degree days for the same time period; during the cooling season, compare your energy use to the number of cooling degree days. Heating and cooling…

Certain telltale signs indicate it’s time to consider replacing heating and cooling equipment or improving the performance of your overall system. It may be time to call a professional contractor to help you make a change if: Your heat pump or air conditioner is more than 10 years old. Consider replacing with ENERGY STAR qualified…

The moisture they add to dry air also helps alleviate common nuisances brought on by winter heating, such as static electricity, peeling wallpaper, and cracks in paint and furniture. However, excess moisture can encourage the growth…

Most air conditioners have their capacity rated in BTUs, or British Thermal Units. A BTU is, generally, the amount of heat required to raise the temperature of one pound of water one degree F. Specifically, a BTU is 1,055 joules, but the first definition is easier to understand in real-life terms. One “ton”, in heating…

Tips: Heating & Cooling Household Heating Systems: Although several different types of fuels are available to heat our homes, nearly half of us use natural gas. | Source: Buildings Energy Data Book 2011, 2.1.1 Residential Primary Energy Consumption, by Year and Fuel Type (Quadrillion Btu and Percent of Total). Heating and cooling your home uses…

Annual Fuel Utilization Efficiency (AFUE): The Annual Fuel Utilization Efficiency (AFUE) rating, indicates how well a furnace converts energy into usable heat. The rating is expressed as a percentage of the annual output of heat (output rating in Btus — British thermal units, a measure of energy) to the annual energy input to the furnace…
