Power feed connections and sauna heating panels include a power feed having a first insulated conductor electrically coupled to a first terminal and a second insulated conductor electrically coupled to a second terminal. The first and second terminals are electrically coupled with at least one heating element. In some cases the power feed includes a supply portion, a connection portion, and an extension portion. The extension portion has one or more conductors in a twisted configuration extending away from the first and second terminals. In some cases the power feed includes an extension conductor portion coupled to a return conductor portion in a twisted configuration. The extension portion extends away from a second terminal past a second connection point and the return portion returns back to and connects to the second connection point at the second terminal. Methods for providing power connections to heating panels are also provided.

Provided is a heating device for a hot water mat that can minimize noise by a check valve for controlling flow of liquid. The heating device for a hot water mat includes: a water tank having a tub for keeping liquid and a discharge hole formed through a side of a lower portion to discharge the liquid in the tub; a heating module connected to the discharge hole and heating liquid; a separator disposed in the water tank, dividing the tub in to a first compartment at a lower portion and a second compartment at an upper portion, and having a connection hole for connecting the first compartment and the second compartment to each other; and a check valve disposed in the first compartment and opening and closing the connection hole by moving up and down by buoyancy from the liquid in the first compartment.

Described herein is a composite panel that includes a first layer made from an electrically non-conductive material. The composite panel also includes a resistance heater printed onto the first layer. Further, the composite panel includes a second layer adjacent the resistance heater, the resistance heater being positioned between the first layer and the second layer. The second layer is made from an electrically non-conductive material.

A support for the heating elements of radiant coverings and floors includes bosses having a concave surface. In some examples, the concave surface includes at least one adhering low relief that creates an extraction-preventing undercut on the concave surface.

A radiation heating device includes: a planar heat generation layer; a heat generation portion that is provided in the heat generation layer and that generates heat by energization; a plurality of heat radiation portions that are disposed in the heat generation layer and that radiate heat transferred from the heat generation portion; a low heat conduction portion that is provided around each of the heat radiation portions and that has a lower heat conductivity than the heat radiation portions; and a contact detection unit that detects contact of an object with the heat generation layer. The radiation heating device further includes an energization amount decrease unit that decreases an energization amount of the heat generation portion when the contact detection unit detects the contact of the object with the heat generation layer.

The invention relates to a profiled section (10) for temperature-control of a room, said section having a receiving portion (20) for a piping system positioning aid (60), a sealing surface (15), formed at least at the side of the receiving portion (20), and at least one first support (30) for a sealing panel (200), the first support (30) being formed at the side of the receiving portion (20) and pointing in the opposite direction to the sealing surface (15). The invention also relates to a building element assembly (100) comprising a profiled section (10) of this type and to an associated use.

This invention concerns a method of doing business which is combined with several scientific advancements of technological ingenuity that results in a novel way of doing business. It in fact teaches a “business method” which creates an innovative approach to obtain annual multi-billion dollar financial revenue as monthly rental income; which results from a rather large scale residential development community of 2000 dwelling units per 50 acre parcels; each parcel being developed upon heretofore 10,000 separately abandoned “Municipal Solid Waste” MSW landfill sites throughout the United States. These apartments are exclusively geared as rentals of a 1,020 square foot-two-bedroom apartment dwellings for only Covid-19 “First Responders” and military service personnel, for the unprecedented sum of just $800/month rent. Additionally, as a supplemental “business method” approach, this instant business model also teaches how to solve the nation's Municipal Solid Waste MSW disposal problems forever into the future as an ingenious viable solution into perpetuity. Moreover, it is further postulated within this business model that further collateral financial revenue automatically inures as a natural business consequence of the sheer necessary and vital purchase of construction materials needed herein, thus positioned as a leveraged-buyout; whereby this 76 billion dollar opportunity now becomes an integral adjunct to this unique business model by adopting a “Home Depot” type retail business concept structure as additional revenue sharing for this inventor's shareholders.

A heating panel including a thermally conductive (e.g. metal) layer, a laminar heating element disposed over a framing-facing side of the thermally conductive layer, an insulation layer disposed over the laminar heating element, and a room-facing surface layer disposed over at least the room-facing side of the thermally conductive layer. A method for heating a room may include installing at least one heating panel on a ceiling of the room and providing power to the heating element to generate heat that radiates into the room. The panel may be part of a heating system including a controller, such as a thermostat, for regulating power to the heating panel. A plurality of heating panels or a plurality of heating zones in one or more of the panels may be independently controllable.
