A maximum air temperature of 50 °C (122 °F) is applied, to prevent any possible smell of scorching from dust that escapes the filters in the system. Beyond the recovery of heat by the heat recovery ventilation unit, a well-designed passive house in the European climate should not need any supplemental heat source if the heating load is kept ...
An improperly used or built outdoor wood boiler can produce wood smoke with excessive unburned particulate matter, but when properly burned, studies show that burning wood is still one of the most environmentally friendly heating options. In 2007, EPA began a voluntary program to encourage manufacturers to reduce particulate levels.
Low-power or insulated versions of these devices give off less heat for the air conditioning to remove. The air conditioning system can also improve efficiency by using a heat sink that is cooler than the standard air heat exchanger, such as geothermal or water. In cold climates, heating air and water is a major demand for household energy use.
A heat pump might use 1 J for every 4 J it delivers giving a COP of 4. A system that only uses a 30 W fan to more-evenly distribute 10 kW of solar heat through an entire house would have a COP of 300. Passive solar building design is often a foundational element of a cost-effective zero energy building.
