Definitions

  • This invention relates to a heating unit suitable for use as a plinth heater, and to a heating installation comprising such a heating unit installed in a building structure or article of furniture, such as a kitchen unit, to serve as a plinth heater.
  • a heating installation adapted so that the heating unit is substantially hidden from view.
  • plinth refers to the lowermost front-facing panel of a building structure or article of furniture, such as a floor-mounted kitchen unit.
  • plinth heaters At the bottom of kitchen units, to provide space heating for kitchens. Such heaters have the advantage of providing space heating without requiring wall space such as would be required by radiators. This is an important consideration in kitchens, where there is likely to be minimal available wall space due to the presence of fitted kitchen units. Plinth heaters further save space by being housed in the otherwise redundant space under kitchen units.
  • Typical plinth heating units may either have an electric heating element, or may comprise a hydronic or 'wet' heat exchanger in communication with a domestic hot water heating system.
  • plinth heaters are regarded as being unsightly, due to the front grille outlet portion of the heater being mounted directly in the plinth of the kitchen unit. This necessitates forming a large hole in the plinth in which to mount the grille outlet, which is considered to spoil the overall look of the kitchen unit.
  • underfloor heating As an alternative space saving option for heating kitchens, the use of underfloor heating has become popular. However, this is costly and inconvenient to install. Additionally, underfloor heating does not benefit from the same degree of controllability as a plinth heater.
  • the present invention seeks to address the above issues by providing an improved and unique plinth heater system which retains the low installation cost benefits of a conventional plinth heater, whilst enabling the outlets to be more aesthetically pleasing by enabling their size to be reduced, and also enabling them to be positioned in discrete and/or concealed locations.
  • the invention also seeks to provide flexibility in the selection of locations for such outlets. Adaptations to the components of the heating unit also serve to enhance its efficiency compared to conventional plinth heaters.
  • the present invention has been developed in particular for installation in kitchen units and is therefore described herein with particular reference to that application. However, it should be understood that the invention may also be installed in other building structures or articles of furniture, and in other domestic, commercial and industrial settings, and such applications are within the scope of the present invention.
  • a heating unit comprising:
  • At least one heat exchanger coil disposed within said housing, in communication with a domestic hot water and/or heating system

  • the unit comprises first and second spigot connector sets, said first spigot connector set being formed in the housing adjacent the first heat exchanger coil and adapted to transfer heated air from said first heat exchanger coil to a first outlet set, and said second spigot connector set being formed in the housing adjacent the second heat exchanger coil and adapted to transfer heated air from said second heat exchanger coil to a second outlet set.
  • the electrically driven fan is preferably a backwards curved fan.
  • the fan may preferably be either an electrically commutated (EC) or alternating current (AC) fan, and preferably has a diameter in the range of from 133 to 190 mm.
  • EC electrically commutated
  • AC alternating current
  • the fan housing should preferably be adapted to accommodate modular controls.
  • the fan is preferably further provided with a low temperature cut-out (LTC) control adapted to operate at a temperature in the range of from 35 to 38 °C.
  • LTC low temperature cut-out
  • An air inlet is preferably formed in the housing of the heating unit. Most preferably, the air inlet is aligned with the air intake of the electrically driven fan.
  • the or each spigot connector set may preferably each comprise two, three or more spigot connectors.
  • Each said spigot connector is adapted to transfer heated air from the adjacent heat exchanger coil, via a duct, to an outlet.
  • the spigot connectors preferably have a diameter of around 50mm. In embodiments having first and second spigot connector sets, these are preferably located on opposed sides of the housing.
  • the housing preferably has a height of around 100mm, in order that unit can fit in standard plinth spaces having heights of 120mm or 150mm.
  • the housing may have a preferred depth of around 250mm.
  • the heating unit preferably has a maximum power output of around 3kW and a maximum heat output of around 10,000 BTU.
  • the heating unit according to the first aspect of the present invention is intended for installation in combination with one or more ducts arranged to transfer heated air from the unit to one or more outlets located remotely from the unit.
  • a heating installation comprising:
  • At least one duct set comprising one or more ducts, connected to said spigot connector set and arranged to transfer heated air to said outlet set.
  • the heating unit comprises a single heat exchanger coil.
  • the heating unit comprises a single heat exchanger coil.
  • the heating unit is as hereinbefore described with reference to the second major embodiment of the first aspect of the present invention.
  • the installation comprises first and second outlet sets, said first outlet set being in communication with the first spigot connector set of the heating unit, and said second outlet set being in communication with the second spigot connector set of the heating unit;
  • the installation comprises first and second duct sets, said first duct set being connected to the first spigot connector set and arranged to transfer heated air to the first outlet set, and said second duct set being connected to the second spigot connector set and arranged to transfer heated air to the second outlet set.

  • the or each duct set may preferably comprise two, three or more ducts, in order to correspond to the number of spigot connectors in the or each spigot connector sets, and the number of outlets in the or each outlet set.
  • Each duct preferably has a diameter of around 50mm, in order to match that of the spigot connectors.
  • the heating unit is preferably supplied with ducting having a maximum length of around 10m. This may be cut to the required length and divided as required between the ducts utilised in the installation.
  • At least one, and preferably each, said outlet is mounted at a location remote from the housing of said heating unit. At least one, and more preferably each, said outlet may be mounted on a surface of a building structure or an article of furniture, said heating unit being housed within an internal space of said building structure or article of furniture.
  • At least one, and preferably each, said outlet is mounted on a surface of a kitchen unit, said heating unit being housed within an internal space of said kitchen unit.
  • Said at least one outlet may desirably be mounted in, on, or closely adjacent a plinth of said kitchen unit.
  • at least one said outlet may desirably be mounted on a surface of a kitchen unit other than a plinth of said unit.
  • At least one, and preferably each, said outlet is mounted in a discrete position so as to enhance the aesthetic qualities of the installation.
  • Each outlet preferably comprises an outlet grille, of a size and shape adapted such that said outlet grille is not normally visible when mounted in said discrete position.
  • the desired effect of having the outlet located on a plinth of a kitchen unit, but yet being at a discrete, and not normally visible position could be achieved by providing a narrow, elongated outlet grille along the top edge of a plinth, where its position would normally be concealed by over-hanging doors of the kitchen unit.
  • Other suitable alternative forms of outlet grille include circular outlets, preferably having a diameter of around 70mm, or rectangular outlets similar to demister vents used in cars.
  • a further advantage of the present invention over conventional plinth heaters is that the arrangement described herein results in reduced noise when the heating unit is operating. This is because the heating unit of the present invention may be located at the back of a kitchen unit, and transfers heated air via ducts to small outlets located remotely from the heating unit. This allows for reduced sound transfer compared to conventional plinth heaters which, by contrast, must be mounted at the front of a unit and transfer heated air out directly via a large aperture in the plinth.
