Profile: Boxx Underfloor Heating Ltd. specializes in supply and installation of electric and warm water underfloor heating systems. Our underfloor heating includes wet systems, where warm water circulates through polyethylene pipes and electric systems which is electric matting. Our underfloor heating systems are designed to produce a radiant-heated zone of comfortable temperature, which extends from the floor to a normal ceiling height of around 8 feet. Our heating cables include twin core construction; which means one cable per heating unit has to be connected to the junction box for making the installation simple.
