Energy efficiency
Double wall heat exchanger
Energy; Energy efficiency
A heat exchanger in a solar water heating system that has two distinct walls between the heat transfer fluid and the domestic water, to ensure that there is no mixing of the two.
Water jacket
Energy; Energy efficiency
A heat exchanger element enclosed in a boiler. Water is circulated with a pump through the jacket where it picks up heat from the combustion chamber after which the heated water circulates to heat ...
Fan coil
Energy; Energy efficiency
A heat exchanger coil in which a fluid such as water is circulated and a fan blows air over the coil to distribute heat or cool air to the different rooms.
Point-contact cell
Energy; Energy efficiency
A high efficiency silicon photovoltaic concentrator cell that employs light trapping techniques and point-diffused contacts on the rear surface for current collection.
Hot air furnace
Energy; Energy efficiency
A heating unit where heat is distributed by means of convection or fans.
Radiant heating system
Energy; Energy efficiency
A heating system where heat is supplied (radiated) into a room by means of heated surfaces, such as electric resistance elements, hot water (hydronic) radiators, etc.
Sealed combustion heating system
Energy; Energy efficiency
A heating system that uses only outside air for combustion and vents combustion gases directly to the outdoors. These systems are less likely to backdraft and to negatively affect indoor air quality.
