About :

Heating load: https://schlau-sanieren.de Standard outside temperature: https://www.waermepumpe.de/normen-tec... You can find the performance curves in the manufacturers' data sheets. Our video is about the correct dimensioning of heat pumps, as incorrect dimensioning can be expensive and inefficient. A heat pump that is too small leads to frequent use of the heating element, which converts electricity into heat in a 1:1 ratio, in contrast to the more effective heat pump (1:3 to 1:6). A heat pump that is too large, on the other hand, consumes unnecessary amounts of energy and has a shorter service life. Daniel Then from AIT Wärmepumpen explains the steps for precise dimensioning. Heating load calculations according to the standard (DIN 12831) and individual energy consumption are important. The requirement is often overestimated because safety surcharges are added to the already oversized consumption. A tightly dimensioned heat pump, well coordinated with the heat source, works more efficiently. The electric heating element can help with calculation errors, but should be used sparingly due to its high energy consumption. The bivalence point at which the heating element is switched on should be between -2 and -7 degrees Celsius. Three values are needed for practical calculations: heating load, standard outside temperature and the performance curve of the heat pump. The video emphasizes the importance of calculating the heating load for each room and gives tips on which questions you should ask the heating engineer in order to get a well-dimensioned heat pump.
