Cable floor.
This design is a heating cable, neatly laid on a special grid and firmly fixed on it using the tape. Thus, peculiar mats are obtained, which later it is very easy to mount in the rooms — it is enough just to roll out the warm floor of mats on the draft floor and reliably fix it. The main advantages of such a heating system are high heat transfer and amazing durability (at least 15 years of impeccable service).
