Component heating
A component heater is a heater integrated into a component ( e.g. wall, ceiling ) that heats the component. The building is then heated by the heat emanating from the heated component ( surface heating ).
As a rule, the component heating is implemented using pipes or pipe mats integrated into solid components , in which a heat transfer medium ( e.g. water ) circulates. With this functional principle, it is also possible to cool the building by passing cool liquid through the pipe system; one then speaks of component conditioning .
A characteristic of this form of heating is the inertia caused by the heat-storing masses. The already existing storage mass of the building can be used for discontinuously available heat sources or to absorb peaks in demand. Since heat has to be fed to the storage tank ( or removed in the case of cooling ) in response to the demand in the ( near ) future, and the current heat output of the components cannot be controlled, predictive control is required. If necessary ( e.g. in the event of unexpected warming due to solar radiation through the windows when there is no shade ), excess heat will have to be ventilated away.
Another characteristic is the increased share of radiant heat due to the large room-side surfaces , which u. a. leads to lower convection - a frequently mentioned energy saving through lower air temperature is only relevant in special situations ( e.g. entrance areas with strong air exchange ). Further advantages result from the use of solar heat and heat pumps , but with a rapid change in demand there are disadvantages ( e.g. occupancy of hotel rooms ), so that the use depends on the demand situation. The turnover with component heating in Austria in 2014 was 70.5 million euros.
