<p>The equipment includes a tepidarium room with walls of insulation boards, the sides of which that face the room carrying an electrically-conductive meander band that serves as a surface heating element covered with an insulating plastic foil and shielded by a metal foil. The equipment includes means to increase the transfer of heat from the heating element to the heat-radiating surface of the insulation boards, a coating which reflects radiant heat on the parts of the room enclosure that are not directly heated, ventilating openings in the walls close to the cold floor by which the room air temperature can be lowered draft-free at least 4.degree.C below the mean radiation temperature, a control device for the automatic adjustment of the mean radiation temperature, a fault current safety switch, and an alarm system activated upon failure of the energy supply or upon occurrence of an impermissibly high temperature.</p> |
