Heating knowledge

The heat pump technology is one kind of new energy conservation refrigeration heating technology, since long mainly applies in building’s heating air conditioning domain. Because the heat pump system heat falls in the energy conservation consumes and the environmental protection aspect good performance, the hygienic hot water supply system also more and more use heat […]

China-heatpump.com has figured out a way to get air source heat pumps –the basis for heating and cooling systems for working in super cold climates. For residents in the Northeast and Midwest, that’s good news. Electric heat pumps are more efficient than fossil fuel heating systems and double as air conditioners in the summer. The […]

Sue Butler decided it was time to cut the cord on fossil fuels. So when her aging gas furnace needed replacing, she turned to the Earth for a solution. She installed a geothermal system–also called a ground-source heat pump, a water-source heat pump, or geo-exchange system–which recently started heating and cooling her Cambridge, Mass. home. […]

The response from homeowners with newly installed solar panels is to excitedly watch the utility meter run backwards–“Look, I’m making electricity!” But for me, it’s been two years and I’m still checking the meter because I’m so close to that magic number–zero. With grid-tied solar photovoltaic panels, you get what’s called a net meter (unrelated […]

NARRAGANSET, R.I.–Homeowner Kim Hageman wanted to “go green” at home without giving up any digital comforts. Three weeks ago, the public relations and marketing executive, her husband, and their two children moved into a house built from the ground up to be both low energy and high tech. It is the first home to get […]

After nearly two years of preparation, teams of architecture and engineering students will soon open the doors on a cluster of 20 solar-powered homes on the National Mall. The teams, from colleges in the U.S., Canada, Puerto Rico, and Europe, are competitors in the Solar Decathlon, a Department of Energy-sponsored contest designed to showcase the […]

A Holland engineering company has designed a heat-absorbing road that bridges winter and summer. Road Energy Systems: using summer sun to clear icy roads. (Credit:Ooms Avenhorn) The Road Energy System, from Ooms Avenhorn Holding, is essentially an asphalt road with tubes placed underneath. Water circulates to siphon off the heat from the road and it […]

Team Germany’s winning SurPlusHome (Credit:Department of Energy) A high-tech building covered on all sides with solar cells has won an international contest for the best home powered only by the sun. Team Germany, which also won in 2007, took first place in the Solar Decathlon, beating out teams from Illinois and California. At a ceremony […]
