A support structure for a heating or cooling system includes a plurality of projections designed to be capable of retaining one or more thermal elements positioned adjacent thereto. The projections are positioned so as to form a first set of substantially parallel undulating channels, each channel having one of the projections forming at least a part of the inner radius of each undulation, with each projection having a recess formed in a side wall thereof facing said channel. The undulations of the channel ensure that a thermal element positioned in the channel will make contact with the projections each time it has to bend around one, without requiring spacing of the projections to squeeze the thermal element. The thermal element can thus be held securely without any play (unwanted lateral movement) in a channel that is slightly wider than the thermal element. Recesses in the channels at the contact points also restrict movement in the vertical direction, thus preventing the thermal element from ‘popping out’ of the channel, while not requiring any restriction narrower than the thermal element.

The present invention relates to a Korean underfloor heating block set, and more specifically, to a Korean underfloor heating block set which makes it possible to more easily and quickly construct a Korean underfloor heating system when constructing or repairing Korean underfloor heating system of a structure such as a building, an apartment, a general house, etc., as well as to create a more eco-friendly residential space while providing effects beneficial to a human body through loess, sericite, precious serpentine, and gelite. Through the present invention, provided is an effect that makes it possible to safely insert, without misalignment, an XL-pipe that is bent to be rounded at a corner or an edge, by forming a lower plate pipe (110) and an upper plate pipe (210) to include a U-shaped pipe portion, a curved branch type pipe portion, and a linear type pipe portion.

Various implementations include a corrugated concrete floor system that includes a plurality of elongated pre-cast concrete floor support units disposed in a horizontal arrangement relative to each other for each floor of a building. The concrete floor support units are disposed between floors of a multi-story building. The units define a plurality of supply air plenums and return air plenums that are arranged alternately in the sandwich space between each floor. The supply air plenums are in fluid communication with the building level above them, and the return air plenums are in fluid communication with the building level below them. By having the supply-air plenum and the return-air plenum share the volume occupied by concrete floor support units, the height of the sandwich space is reduced.

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 heating system is configured to optimize the speed and accuracy of the system in achieving various ambient air temperature setpoints, by modulating the heated water supply water setpoint to optimize the slope of the system's response curve. Optimized response curves are automatically determined by analyzing differences between ambient air temperatures over time in response to modulated supply water temperatures as they are reset upward or downward to achieve response times prioritized for improved occupant comfort. The controller of the heating system calculates a temperature slope, and adjusts the supply water setpoint to increase/decrease the speed of ambient temperature rise to achieve a desired slope.
