A domestic storage heater which uses cheap night time electricity to heat ceramic bricks which then release their heat during the day. A storage heater or heat bank (Australia) is an electrical heater which stores thermal energy during the evening, or at night when electricity is available at lower cost, and releases the heat during the day as required.
Electric fan heater. A fan heater, also called a blow heater, is a heater that works by using a fan to pass air over a heat source (e.g. a heating element). [1] This heats up the air, which then leaves the heater, warming up the surrounding room. They can heat an enclosed space such as a room faster than a heater without a fan, [2] but like any ...
Furring strips are applied to the sheathing to create a vented air space between the radiant barrier and the siding, and vents are used at the top and bottom to allow convective heat to rise naturally to the attic. If brick is being used on the exterior, then a vented air space may already be present, and furring strips are not necessary.
Portable immersion heaters may not have a control thermostat, since they are intended to be used only briefly and under control of an operator. For domestic hot water supply, or industrial process hot water, permanently installed heating elements in an insulated hot water tank may be used, controlled by a thermostat to regulate temperature.
In buildings, the radiant heat flow between two internal surfaces (or a surface and a person) is influenced by the emissivity of the heat emitting surface and by the view factor between this surface and the receptive surface (object or person) in the room. [38] Thermal (longwave) radiation travels at the speed of light, in straight lines. [9]
Avoiding the use of heaters near flammable materials such as paint or gasoline. Installing smoke alarms and carbon monoxide detectors nearby. The risk of fire (and burns) is sometimes less with oil-filled heaters than those with fans, [8] [9] but some fan-assisted heaters have a lower risk of fire (and burns) than other oil-filled heaters. [10]
The thermostat controls the fan speed and/or the flow of water or refrigerant to the heat exchanger using a control valve. Due to their simplicity, flexibility, and easy maintenance, fan coil units can be more economical to install than ducted 100% fresh air systems (VAV) or central heating systems with air handling units or chilled beams. FCUs ...
Electric heaters are usually part of a fan coil which is part of a central air conditioner. They circulate heat by blowing air across the heating element which is supplied to the furnace through return air ducts. Blowers in electric furnaces move air over one to five resistance coils or elements which are usually rated at five kilowatts.
