A thermal device comprising a heatable and ventilatable thermal cabin (2) for at least one person is equipped with adjustable heating means (4) and with adjustable ventilation means (6) and, optionally, with a temperate sensor (8). Furthermore, detection means (10) are available for the continuous detection of the presence of persons situated in the thermal cabin, wherein said detection means interact with a heating control device (12) for the heating means (4). Due to the fact that a base heating power can be set when no one is present and that a comparatively higher operational heating power can be set when someone is present, the energy requirement when operating the thermal facility can be reduced considerably.

A graphene nano-steam generator and a beauty instrument are provided. The graphene nano-steam generator includes a coarse steam channel, a nano-steam channel and a high-voltage power supply device. The coarse steam channel is connected to a coarse steam manufacturing device and the nano-steam channel. The coarse steam channel is provided with a steam sieving device, and an end of the coarse steam channel is provided with a first electrode and a second electrode. The high-voltage power supply device is coupled to the first electrode and the second electrode. The high-voltage power supply device supplies high-voltage electricity to the first electrode and the second electrode, and forms a high-voltage arc discharge between the first electrode and the second electrode, thus the coarse steam molecular group flowing through is ionized by the high-voltage arc to generate a large amount of active nano-scale steam to be flowed out from the nano-steam channel.

Systems may include a heater including a plurality of heating elements that may include a first heating element configured to generate heat based on a first current, and a second heating element configured to generate heat based on a second current. Systems may further include an electromagnetic (EM) radiation reducing device configured to cancel electromagnetic emissions from the heater. The EM radiation reducing device may include a first EM radiation reduction element positioned adjacent to a first side of the heater, and a second EM radiation reduction element positioned adjacent to a second side of the heater, where the first and second EM radiation reduction elements have geometries configured based, at least in part, on the heater.

Modular infrared heater units for a sauna and methods for constructing a sauna. The infrared heater units include one or more heating elements disposed in a housing. The housing is configured for direct mounting on walls of a structure and includes a pigtail for coupling to a controller. The housing is dimensioned to accommodate a paneling or other cladding on the walls and includes a trim frame that obscures edges of the cladding adjacent to the heater unit. Construction of a sauna unit includes mounting of a plurality of the heater units on walls of the structure; electrically communicably coupling the heater units to a controller; and providing any desired cladding to the interior of the structure.

Systems and methods are provided for controlling infrared radiation (IR) sources of a sauna including tuning IR wavelength-ranges and radiated power-levels of IR sources, and directing IR to locations on a user's body. In one illustrative embodiment, a sauna may be provided having adjustable IR emitters to emit IR at any wavelength resulting in a desirable radiation treatment for the sauna user. In another illustrative embodiment, a method is provided for tuning IR emitters in a sauna.
