HEAT LOSSES
Repective insulation for limiting heat losses is also required for the (Figures 17, 18, 19 and 20) show the linear heat losses of the tubes
tubes in the XPress system, not just to save energy but also based according to their diameter and temperature difference. The details
on current norms and legal provisions (for example German law of in figures 17, 18 and 19 refer to bare tubes placed above screed.
10/91, DIN 1988, part 2, EnEV). We refer to these regulations and Figure 20 shows the heat loss for polypropylene coated tubes.
their implementation regulations and the respective tables showing
the minimum insulation thickness.
