Underfloor heating cable can be laid screed up to 3-5 cm for main or additional heating.
Main or additional heating. For additional heating (in addition to the Central or individual), choose a power of 15 W/m. For rooms where the heating cable acts as the main source of heat, choose 18 W/m.
Two-core or single-core. Two-core – slightly more expensive, easier to install, heats up faster (than single-core). Single-core – cheaper, but harder to install. Requires preliminary calculations of the laying area due to the design of the cable. High mechanical strength. For installation in warehouses with a high load on the floor screed, choose SN-15, SN-18.
We recommend buying "warm floor SN-15": it fits in a screed, fast heating, installation is easier than single-core, reliable due to the possibility of a small overheating.
