Alcoholic? 5 Signs to Recognise the Condition

"How can anything be more than 100 percent energy efficient?" Remember, we are talking about how efficiently a unit uses either electricity or gas to move or create heat. I know what you are thinking. An 80-percent efficiency rating means that 80 percent of the gas used will provide heat and the other 20 percent goes up the flue. My favorite system, the geothermal heat pump, is simply the very best there is. Another popular type of heating system, an air-to-air heat pump, uses electricity instead of gas. An air-to-air heat pump, properly installed, would operate at an efficiency of around 250 percent. And when I talk about heating efficiency, I'm talking about how efficiently the system converts either natural gas or electricity to heat for you home. Air-to-air pumps extract the heat from the air. A typical gas furnace will be rated at about 80 percent efficiency when it is new and if it is installed properly. Many times people are confused by inaccurate information they receive from manufacturers and sellers of heating and cooling equipment. With a heat pump, you use one unit of electricity and get about 2. Unlike a gas-fired furnace, a heat pump does not actually create heat, it simply moves heat from one location to another. That percentage will lessen with each year's use. 5 units of heat. At first glance, you might think 80 to 90 percent sounds pretty good.
