In my quest to educate the world on building science topics, I find that I often have to go back to basics. Whether it s the basic nature of heat, why we re using the wrong quantity to characterize infiltration rates, or the reason that the media s focus on caulking windows drives me crazy, I try to find the fundamental issues involved and explain them in terms that are easy…

Simply stated a heat pump is an electrically driven mechanical device which absorbs heat energy at one location and transfers it to another. Geothermal heat pumps use the natural heat storage ability of the earth or the earth s groundwater to heat and cool your home or business. Energy can exist around us in the form of heat, light, mechanical, electrical or chemical energy…

One great way to get more efficient heating and cooling in your home is with a heat pump. But don t think heat pumps are just for heating. Many can be used for both heating and air conditioning. In fact, many ductless mini-split air conditioning units also operate as heat pumps. A heat pump is equipment that uses a refrigerant to move heat from one place to another. During…

One of the main reasons that homeowners have heat pumps installed in the first place is because they provide a fantastic “two-in-one” package deal: an air conditioner and a heating system. It only takes a single adjustment on a thermostat to change a heat pump from heating mode to cooling mode and vice versa . But are heat pumps equally effective at heating as they are at cooling?…

Should you use natural gas heating rather than a heat pump in your home? Some say the interest in heat pumps is fueled by irrational exuberance. Others say that because they require supplemental heat, heat pump performance is not acceptable. Another group says you ll get a better HERS Index by using gas heat. So how s a person to decide? Some of the folks who say these things…

When matched with a variable speed indoor unit from Trane, the XL20i has another special feature. Its a method of enhancing airflow that we call Comfort-R™ and it gives you greater humidity control in cooling. This is accomplished by running the fan at a slower speed during start-up. Comfort-R™ also provides warmer air during heating start-up. These managed cycles reduce temperature…

Because of these concerns, the governments of Canada and the United States, along with representatives of other countries, have signed an agreement to phaseout the production and use of HCFC. The phaseout timetable, which actually began over 10 years ago, takes place in stages, with a critical milestone coming at the beginning of 2010. After January 1, 2010, manufacturers can…

Heat pumps are the most efficient form of electric heating in moderate climates, providing up to three times more heat than the energy they use. Today s heat pump can reduce your electricity use for heating by approximately 50% compared to electric resistance heating such as furnaces and baseboard heaters. A heat pump does double duty as a central air conditioner by collecting…

Technically, a heat pump is a mechanical-compression cycle refrigeration system that can be reversed to either heat or cool a controlled space. Installation for this type of system typically consists of two parts: an indoor unit called an air handler and an outdoor unit similar to a central air conditioner, but referred to as a heat pump. A compressor circulates refrigerant…

Heating and cooling a house used to be separate jobs, but the heat pump, a device that does both, often at much lower cost, is gaining popularity. Nearly one in three new American houses uses a heat pump, according to a recent Government estimate; in some parts of the country heat pumps are nearly universal in new houses. A heat pump is nothing more than a glorified air-conditioner,said…

Most residential heat pumps are of the air-source type whereby heat is transferred from the outdoor air to a refrigerant in the outdoor section and then transferred from the refrigerant to the indoor air in the air handler (fan/coil). When the outdoor air temperature decreases the COP and heating capacity of the heat pump decrease while the heat loss from the heated structure…
