An underlayment system is provided that includes a plurality of bosses that emanate form a common base member. The bosses and bases preferably include an opening therethrough that will allow for subsequent layers of adhesive to interact and bond to each other. The bosses are also spaced in such a way to help secure a wire snugly therebetween.

A hydronic floor heating system as it relates to an HVAC apparatus, approach and system. Aspects of the present system and approach may include a radiant floor optimization mode, low floor temperature in vacation mode, modifying a 300 Hz, or so, reading principle base on implementation of Pseudo-random jittering of a reading event improving short-term accuracy of the individual readings, and a combination of hardware and software filters for using thermal sensors with extended cable length.

Methods and functional elements for enhanced thermal management of predominantly enclosed spaces to enable the construction of buildings with reduced power requirements for heating and/or air-conditioning systems. The methods may be in part based on dynamically changing functional elements with variable properties, or effective properties, in terms of their electromagnetic radiative behavior and/or their thermal energy storage properties, or the spatial distribution of the stored thermal energy, which permits the application of methods to control the overall thermal behavior of the entire structure in such a way that desired levels of inside temperature can be reached with reduced consumption of external energy (typically electricity, gas, oil, or coal). In some instances no conventional heating of cooling is required at all. In some instances the invention reduces the time to reach desired temperatures inside such buildings, habitats, or other predominantly enclosed spaces.

A prefabricated construction wall assembly comprising: a frame structure having a first thermal expansion coefficient; and a panel configured for covering at least a majority of the a face of the frame structure, said panel having a second thermal expansion coefficient different from the first thermal expansion coefficient, and a solid-surface exterior face exposed to an exterior of the wall assembly and an interior face connected to the face of the frame structure so as to withstand the thermal structural differences between the frame structure and the exterior face.

The invention is, in one aspect, a system for heating or cooling a room, including a radiant panel with fluid conduit, which, radiates energy to a room. A heat exchange device exchanges energy between the fluid in the radiant panel and an exchange medium. A vent allows fresh air to enter a room, moved by a fan. The fan propels the air through a chamber for heating or cooling the air, wherein the chamber at least partially comprises the radiant panel.

Methods, systems and devices for making a pedestrian, vehicular, or other surface resistant to frost, snow and ice by use of heat are disclosed. A composite base or deck element includes a recess to accommodate heating element. A thermal insulator has an upward facing layer of heat-conductive aluminum foil, above which sits the heating element. On top is a pedestrian, vehicular, or other exposed surface, for example a tactile warning surface.
