The use of residential air-to-air heat exchangers has been proposed as a possible strategy to assure that indoor air quality is not substantially degraded by house tightening. We examine the energy impact and cost effectiveness of heat exchanger utilization in tightened homes in the BPA region. ...
Instead of using pumps or heat transfer fluid, they use thermodynamics, pressure, or gravity to feed water to the home. There are also two main types: Integral collector-storage (ICS) systems have combined collectors and storage tanks, making them heavy and not suitable for some homes. ...

However, during the last decade, not only has climate change had an impact on citizens but also the Internet of Things (IoT). This technology has a great impact on cities, homes, and industries by making it possible to monitor the state of these kinds of infrastructures. IoT allows ...
Installing attic fans or vents costs$400 to $900. The price relates to the type of fan and its location. Attic fans reduce the amount of heat that rises to the roof. They’re ideal for homeowners who want to cut down on their air conditioning use in the summer. They also help to ma...
Oil boilers can produce hot water for hydronic heating or steam for steam heat. Oil water boilers are more common, as are hydronic heating systems. Steam radiators tend to be part of older systems and are not as common in residential settings. However, many are installed in older homes, and...

Energy recovery ventilators, an improved version of an air exchanger, save energy by recovering some of that energy before it leaves your home. The national average for an energy recovery ventilator with installation is roughly $2,000. This number varies by region due to the cost of labor, ...
One heat source delivers heat at ambient temperature using a ground heat exchanger. The other source is waste heat e.g. from an industrial process. Regarding the heat pump and heat consumer, this kind of systems are already widely used for private homes. Regarding the heat source the concept...
