New York City law regulates the safety of space heaters. Space heaters for sale in the city must have a thermostat to control temperature, an automatic shut-off feature if the heater tips over or overheats, and must be certified and labeled by a nationally approved organization or laboratory. [15]
30 kW resistance heating coils This radiant heater uses tungsten halogen lamps. Electric heating is a process in which electrical energy is converted directly to heat energy. Common applications include space heating, cooking, water heating and industrial processes. An electric heater is an electrical device that converts an electric current ...
A ceramic heater as a consumer product is a space heater that generates heat using a heating element of ceramic with a positive temperature coefficient (PTC). [1] [2] [failed verification] Ceramic heaters are usually portable and typically used for heating a room or small office, and are of similar utility to metal-element fan heaters.
Space heaters are repeatedly linked with tragedies. Local fire departments responded to an estimated average of 44,210 home structure fires caused by heating equipment, including space heaters ...
Infrared heaters can be operated in vacuum or atmosphere. One classification of infrared heaters is by the wavelength bands of infrared emission. Short wave or near infrared for the range from 750 nm to 1.4 μm; these emitters are also named "bright" because still some visible light is emitted; Medium infrared for the range between 1.4 μm and ...
This heated air is then ducted to the building space or to the process area where the heated air is used for space heating or process heating needs. Functioning in a similar manner as a conventional forced-air furnace, solar-thermal-air systems provide heat by circulating air over an energy collecting surface, absorbing the sun's thermal energy ...
However, if a building does need full heating, combustion central heating may offer a more environmentally friendly solution than electric resistance heating. This applies when electricity originates from a fossil fuel power station , with up to 60% of the energy in the fuel lost (unless utilized for district heating ) and about 6% in ...
Most systems are usually constructed from 100 to 600 mm (3.9 to 23.6 in) diameter, smooth-walled (so they do not easily trap condensation moisture and mold), rigid or semi-rigid plastic, plastic-coated metal pipes or plastic pipes coated with inner antimicrobial layers, buried 1.5 to 3 m (4.9 to 9.8 ft) underground where the ambient earth ...
