A method and a system for controlling temperature of an indoor space. The space is provided with a conventional heating system and a heater matrix including a plurality of heater pixels embedded in surfaces included in the space. Each heater pixel includes a resistive heater element. The conventional heating system is used for maintaining a basic temperature of the space, the basic temperature being less than a comfortable room temperature. Operation of the heating matrix is selectively controlled for generating one or more areas within the space that have a microclimate with a comfort temperature that is higher than the basic temperature.

The invention relates to a heating mat (4) for a surface heating system (1.1), particularly for heating a room (101) of a building (100), comprising a flexible base unit (10) that has a first carrier element (11) with a planar extension and a first main side (11.1) and a second main side (11.2), and at least one electric heating means (20) for discharging heat. The invention further relates to a surface heating system (1.2) and to a method (200) for producing a heating mat (4).

A floor warming system includes floor warming elements for coupling to a floor and a first sensor assembly for generating a first signal indicative of at least one of a floor temperature and a floor warming element temperature. A thermostat controller receives the first signal and a second signal indicating an ambient outdoor temperature for controlling operation of the floor warming elements. The thermostat controller includes memory storing an instruction set and data related to a user setpoint and a processor for running the instruction set. The processor is operative to calculate an operational floor setpoint based on the first signal, the second signal and the user setpoint.

A system and method for heating structures to either prevent the build-up of freezing precipitation or eliminate freezing precipitation on an exposed outer surface of the structures. The system includes a heating assembly integrally formed with a structure to apply thermal energy to the exposed outer surface of the structure. Optionally, the heating assembly includes heating elements formed of carbon fiber. The system optionally includes a control assembly operatively coupled to the heating assembly. The control assembly selectively powers the heating assembly and can be configured for remote operation. In use, the control assembly can be selectively activated from a remote location to power the heating assembly and heat the structure. Optionally, the structure is a concrete structure.

An adapter device and/or a thermostat device for use during installation and testing of in-floor heating systems. The adapter device allows for temporary electrical interconnection between a mat and an AC power source, and includes at least one switch configured to actuate based on a user-supplied force (e.g., a finger press) to temporarily electrically couple the mat to an AC power source. The at least one switch is further configured to automatically de-actuate in the absence of the user-supplied force to electrically decouple the mat from the AC power source. The thermostat device includes at least one integrated power measurement circuit for testing and diagnostics of an in-floor heating system.

A lightning protective and heating porcelain tile includes a porcelain tile layer, a shell, a metal plate protective layer, and an electric heating film heating layer. The metal plate protective layer is attached to the inner wall of the porcelain tile layer, and the electric heating film heating layer is attached to the metal plate protective layer. The electric heating film heating layer includes an electric heating film, a first lightning protective module and a second lightning protective module.
