Heating mats for semi-storage heating

With regards to functionality, there is no difference between a circuit and a mat – a heating mat is basically a heating cable attached to a fabric base. These two products differ only in the way they are laid. Mats have the benefit of being easier to lay, and with them even spacing of wattage is guaranteed. One of the advantages of the semi-storage system is the lower acquisition costs of heating mats – as the cable is placed in a sufficiently thick layer which will ensure an even distribution of temperatures, cables with higher linear wattage can be used (approx. 15 W/m).

The disadvantage is the more complicated installation method – mainly in situations when the heating cable is supposed to be inside the load-bearing slab. This slab must be monolithic; if a layer of only 2cm were poured in the case of e.g. concrete, a heating cable was installed after the initial layer had set and subsequently a second layer with a thickness of 4cm was poured, there would be a very real danger that these two layers would separate after the commissioning of the heating cable and the floor would “rise”. In the case of semi-storage and storage systems, it is also necessary to strictly follow the gradual start-up procedure for raising the floor temperature – the so-called first heating mode.

For semi-storage heating, we offer LPSV heating mats with a wattage of 100W/m².
