A Case Study in Converting from Two-Pipe Steam to Hydronic Heating
A new flow meter is easier to use than a Duct Blaster, and more accurate than the temperature rise method. [continue reading]
New aerosol spray technology can allow weatherization crews to seal even tiny duct leaks in places that are difficult to reach using conventional methods. [continue reading]
More than three-fifths of the households in the U.S. heat or cool their homes with ducted forced air systems, so chances are good that air ducts are lurking within your walls, floors, or ceilings. [continue reading]
A home with a poor duct system can't be energy efficient no matter how tight or well-insulated it is. [continue reading]
A boiler is generally more fuel efficient than a standard gas water heater, especially when the boiler is fully loaded. [continue reading]
Multifamily buildings with more than five units make up about 17% of all U.S. housing, yet scant information exists on the fuel use of these building in specific locations (see "Multifamily Statistics"). [continue reading]
Ground source heat pumps (sometimes called geothermal heat pumps, Geo-Exchange Systems, or GHPs) most often exchange heat with the ground by means of a ground heat exchanger. [continue reading]
In 1997, Cadet Manufacturing in Vancouver, Washington, issued a recall notice on some of its electric in-wall heaters. The heaters contain limit switches that have been identified as a fire hazard by the U.S. Consumer Product Safety Commission (CPSC). [continue reading]
