▎ 摘　　要

NOVELTY - A heating panel comprises A layer of cementitious substrate (3), a carbon nanotubes (CNTs)/graphene layer (2) applied on the cementitious substrate and at least two electrodes applied on the CNT/graphene layer to enable applying a voltage to the CNT/graphene layer. USE - The heating panel is used for underfloor heating of flooring panels or tiles. ADVANTAGE - The heating panels are simple, inexpensive panels which are resistant to damages caused during installation, hence short-circuit in electric systems and catching of fire are prevented . The underfloor heating systems are effective when used in floor having minimum of 75 mm floor build-up dimension. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for heating panel system which comprises at least two heating panels joined at their edges, by corresponding rebated joints. DESCRIPTION OF DRAWING(S) - The drawing shows sectional view of the heating panel and flooring.
