#Under floor radiant heat windows

So it doesn't matter if some heat is lost when the windows are opened briefly to ventilate the room. The room surfaces absorb the heat and act as a heat store. After less than 15 minutes, the new temperature is set on the ceiling surface and the heating process begins. This means that the ceiling heating can react quickly and be precisely regulated. The thin capillary tube mats lie just below the surface to be tempered. Depending on the floor covering, this problem is exacerbated.

Even complex control systems can only partially compensate for the sluggishness of the underfloor heating. If not so much heat is needed in the room, then the screed heats up as a 'heat store'. If the temperature changes briefly, the underfloor heating usually only reacts after 5 hours and later. The heating screed above the heating pipes builds up a thermal resistance that counteracts efficient heat dissipation into the room. This creates a feeling of cosiness and constant warmth comfort. Objects in the room and all areas surrounding the room are heated evenly by the heat rays from the ceiling heating. New buildings and modernized houses have a low heat requirement of a maximum of 60 W / m² or less. This is another reason why more and more hospitals are opting for heating and cooling ceilings.ĭespite the high proportion of radiant heat, the heating output of the ceiling is sufficient to completely heat the room. This leads to less dust turbulence and fewer allergens in the room air. The heat transfer through convection is much lower with ceiling heating than with underfloor heating. The heat is mainly brought into the room via radiant heat from the ceiling. The thermodynamic connection “warm air rises upwards - cold air falls downwards” is not the driving force behind the warming of ceiling heating. Depending on the flow temperature and duration, the heat from below can become a strain on the blood vessels of the feet and legs. In addition, not all people perceive the warmth on their feet as being pleasant over the long term.

The germ-contaminated air flow in the room can irritate the respiratory tract and the mucous membranes, similar to classic radiator heating. The convection (air movement) in the room leads to the vertical transport of suspended matter and germs from the floor to the living area. The people in the room also absorb heat directly through the contact between their feet and the floor.

The underfloor heating transfers the heat into the room through around 60% radiation and 40% convection (warm air rises upwards). Which system uses the advantages of surface temperature control most efficiently? Underfloor heating or ceiling heating? In the following, the advantages and disadvantages of traditional underfloor heating and ceiling heating with BEKA capillary tube mats are compared. Radiant heating ensures a high level of living comfort and pleasant warmth without the technology visibly influencing the room design. It is also economically feasible to use environmental heat as a heating source. Compared to classical radiator heating technology, surface heating requires low flow temperatures. The reasons for this development can be explained by the advantages of radiant heating. Underfloor heating is also being used more and more frequently in the modernization sector. 50% of new single-family houses in Germany are equipped with underfloor heating. This can be seen in the growth rates in the underfloor heating industry. The future of heating and cooling rooms belongs to radiant heating. Ceiling Heating with Capillary Tube Mats vs.
