Heating cables in cast floors
Direct acting heating systems normally require 60-100 W/m2 (5.5 - 9 W/sq. ft). These systems require low thermal capacity, and the heating cables are placed as close to the floor surface as permitted by the national authorities.
In wet rooms as toilets, bathrooms and washing rooms plates withstanding moisture must be used.
Both TXLP and TKXP can be installed along reinforcement bars. Attach the cable longitudinally to the bars, and avoid stepping on the cable.
The cast is to dry and harden naturally, and the heating cable can be turned on after 6-8 weeks.
It is not recommended to use a dry cast, meaning the use of little water to decrease dry and harden time. If this method is used, ensure that mixing is done by machinery and compacting is done thoroughly.
Screeds and other casts have shorter drying and hardening time.
