Definitions

  • IR radiant heating panels typically use 35-40% less energy compared to conventional convection heating radiators or commonly used underfloor heating.
  • IR heating panels on or in the ceiling can provide flexibility in strategically placing the heat where it is desired, with fewer restrictions than with other types of heating units.
  • Standalone IR heating panels may be hung or suspended from an existing ceiling, but are often obtrusive (i.e prominent and noticeable in an unwelcome way) and therefore may not be visually acceptable to the market.
  • Existing heater applications in the ceiling may be installed behind the ceiling surface panels in the cavity between the ceiling joists in order to be concealed. This can involve using electric cable heater mats or films, wet hydronic pipes, and the like.
  • Typical ceiling constructions comprise surface panels of 12.5mm thick plasterboard or gypsum wallboard sheetrock, which are usually attached to a structure of wood ceiling joists with drywall screws, and are integrated together into a continuous ceiling appearance by using drywall tape and spackle along the seams between the panels.
  • Such installations are relatively inefficient, resulting in heat transfer of only 70-75% of the input energy as radiating heat into the room, according to test data.
  • the efficiency of the IR heat radiation is a function of temperature, in which higher temperature produces more efficient radiation.
  • Existing plasterboard or sheetrock panels are typically limited to a surface temp of 55 degC or less.

  • the heating panel comprises a thermally conductive layer having a room-facing side and a framing-facing side, at least one laminar heating element disposed over the framing-facing side of the thermally conductive layer, an insulation layer disposed over the at least one laminar heating element, and a room-facing surface layer disposed over at least the room facing side of the thermally conductive layer.

  • the protective framing-facing surface layer may comprise a gypsum-reinforced polyester mesh layer bonded to the insulation layer
  • the insulation layer may comprise foam
  • the room-facing surface layer may comprise paper.
  • the thermally conductive layer may comprise a tray having peripheral sidewalls. In such configurations, the room-facing surface layer may wrap around the sidewalls of the tray and may define at least a portion of the framing-facing surface of the panels as well as the peripheral edge surfaces of the panels.
  • the panel may comprise a power cutout switch configured to cutout power to the laminar heating element upon detecting a temperature in the heating panel greater than a predetermined maximum, such as at 80 degrees C.
  • the heating panel may include a plurality of holes extending from a room-facing surface of the panel to a framing-facing surface of the panel, each dimensioned to receive a fastener for fastening the panel to framing of a building.
  • An insulated area may extend between the periphery of the panel and the at least one heating element.
  • the heating panel may comprise two heating elements and may have an insulated area extending between the two heating elements.
  • An electrical enclosure cutout may be defined in the insulation layer, in which the power cord connects to busbars of the laminar heating element, and may have a cover that is flush with the framing-facing surface of the panel.
  • Another aspect of the invention comprises a heating system comprising a heating panel as described herein, in which the power cord is connected to a controller, such as a thermostat, for regulating power to the heating panel.
  • a controller such as a thermostat
  • a plurality of heating panels or a plurality of heating zones in one or more of the panels may be independently controllable by the controller.
  • Still another aspect of the invention includes a method for heating a room, comprising installing at least one heating panel as described herein on a ceiling of the room, and providing power to the at least one heating element to generate heat that radiates into the room.
  • a plurality of heating panels may be connected to a thermostat controller mounted in the room, in which the method comprises controlling heat in the room to achieve a set temperature in the room.
  • the ceiling may include at least one heating panel and at least one non-heating panel, wherein installing the at least one ceiling panel comprises applying a plaster material between the at least one heating panel and the at least one non-heating panel to form a continuous coverable ceiling layer.
  • FIG. 1A is a schematic illustration of a cross section of an exemplary heating panel embodiment.
  • FIG. IB is a schematic illustration of a cross section of another exemplary heating panel embodiment.
  • FIG. 1C is a schematic illustration of a cross section of an exemplary heating panel embodiment having a recess for accommodating a scrim tape disposed between adjacent heating panels to facilitate smooth finishing of the joint therebetween.
  • FIG. 2 is a schematic illustration of a partially transparent plan view of an exemplary heating panel embodiment, showing locations of heating elements relative to the periphery of the panel, and a schematic of control and power elements.

  • a system comprising one or more such ceiling panels may be connected to any standard thermostat to control temperature of the room. Panels may be placed in desirable positions and tailored to maximise the heating requirements of a particular room layout. Advantages of systems comprising such panels include 90% or more energy conversion to radiant heat directed to the room, which may represent 30 -40% energy savings as compared to existing concealed ceiling installations. Additionally, the construction of the ceiling panels permits them to be installed in the same manner as existing insulation boards or sheetrock panels, and the active panel surface may be covered with rendering plaster or any coating similar to plasterboard to permit integration into a continuous surface ceiling suitable for painting or covering with any type of suitable ceiling surface layer. Although the panels may achieve a temperature of 80 degC, the panels are constructed to meet fire requirements. The plug-and-play connectability simplifies installation and allows flexibility in positioning of the panels wherever they are needed. The overall cost of heating system is competitive with, and may be less expensive, with most or all other technologies on the market.
