An oil heater, also known as an oil-filled heater, oil-filled radiator, or column heater, is a common form of convection heater used in domestic heating. Although filled with oil , it is electrically heated and does not involve burning any oil fuel ; the oil is used as a heat reservoir (buffer).
Radiant cooling appears to have lower first costs [17] and lifecycle costs compared to conventional systems. Lower first costs are largely attributed to integration with structure and design elements, while lower life cycle costs result from decreased maintenance.
Several panels may be stacked together to make one radiator, and the resulting radiator is referred to with a two-digit type number. The first digit is the number of panels, and the second is the number of sets of fins, for example a type 21 radiator has two panels with one set of fins in between.
In a steam heating system, each room is equipped with a radiator which is connected to a source of low-pressure steam (a boiler). Steam entering the radiator condenses and gives up its latent heat, returning to liquid water. The radiator in turn heats the air of the room, and provides some direct radiant heat. The condensate water returns to ...
A thermostat exerts control by switching heating or cooling devices on or off, or by regulating the flow of a heat transfer fluid as needed, to maintain the correct temperature. A thermostat can often be the main control unit for a heating or cooling system, in applications ranging from ambient air control to automotive coolant control.
A fan coil unit (FCU), also known as a Vertical Fan Coil Unit (VFCU), is a device consisting of a heat exchanger (coil) and a fan. FCUs are commonly used in HVAC systems of residential, commercial, and industrial buildings that use ducted split air conditioning or central plant cooling.
Ideally, a room will have both heating and cooling registers. In practice, cost considerations usually require that heating and cooling be provided by the same register. In such cases, heating most often takes precedence over cooling, and registers are usually found close to the floor. [7] For heating purposes, a floor register is preferred.
Radiators' weight typically varies from almost nothing, if an existing structural panel is used as a radiator, to around 12 kg/m 2 for a heavy deployable radiator and its support structure. The radiators of the International Space Station are clearly visible as arrays of white square panels attached to the main truss.
