Definitions

  • This invention relates to an energy efficient heating installation for providing heating to a building, and to an energy efficient fan convector unit for use in such an installation.
  • it relates to an energy efficient heating installation utilising a heat pump in place of a conventional oil- or gas-fired boiler, and fan convector heating units in place of conventional radiators.
  • the present invention seeks to address the above issues by providing an energy efficient, fossil fuel free, domestic heating system which will be well within the financial reach of the average consumer. It is envisaged that the purchasing cost of the domestic heating system of the present invention will be recovered through the cost savings attributable to increased energy efficiency well before the end of the system's life cycle. Indeed, it is envisaged that the purchase cost of the domestic heating system of the present invention will be comparable to the purchase cost of conventional condensing boiler based heating system of similar size or capacity.
  • a further aim of the present invention is to provide an alternative energy based domestic heating system which can be simply installed by a qualified plumber, without the need for the involvement of other tradesmen such as alternative energy specialists or electricians.
  • a heating installation comprising:
  • a heat pump having an internal water coil, and fluid connectors adapted to transfer heated water from said coil to a domestic heating system and to receive cooled water returned therefrom;
  • one or more fan convector heating units each having an electrically driven fan and fluid connectors adapted to receive heated water from the heat pump and to return cooled water to the heat pump;
  • control means in electrical communication with the heat pump and each fan convector heating unit(s), and adapted to activate said one or more electrically driven fans upon receipt of an activating signal from the heat pump.
  • fan convector heating unit as used herein is intended to refer to such a unit, also known as a wall-mounting fan convector or fan-assisted radiator, comprising a heat exchanger fed by the central heating system of a building in which the heating unit is installed, and an electric fan arranged to blow air over the heat exchanger.
  • the control means is preferably further adapted to deactivate said one or more electrically driven fans upon receipt of a deactivating signal from the heat pump.
  • the control means preferably is or comprises a low voltage transformer adapted to operate the fan convector heating unit(s) on a low voltage electricity supply.
  • the low voltage transformer is adapted to provide a 12V electricity supply to the fan convector heating units.
  • the low voltage transformer may preferably be housed within the heat pump itself. As such, the heat pump is adapted effectively to activate and deactivate the fan convector heating unit(s) as required.
  • the heat pump is preferably provided with a timed switch, adapted to generate the activating signal to the control means upon the elapse of a predetermined period of time following activation of the heat pump.
  • the timed switch is further adapted to generate the deactivating signal to the control means upon the elapse of a pre-determined period of time following deactivation of the heat pump.
  • the heat pump may optionally be provided with a thermostatic controller adapted to generate the activating signal to the control means upon the temperature of water in the heat pump coil reaching a pre-determined activation temperature.
  • the thermostatic controller is preferably further adapted to generate the deactivating signal to the control means upon the temperature of water in the heat pump coil falling to a predetermined deactivation temperature.
  • the heat pump is preferably an air source heat pump.
  • the heat pump may alternatively be a ground source heat pump - which are generally more efficient at delivering recovered energy to a building - however, these tend to be more expensive than air source heat pumps and therefore do not lend themselves to meeting the aims of the present invention.
  • the heat pump is preferably an air-to-water heat pump.
  • Such heat pumps are designed to operate at a co-efficient of performance (COP) of approximately 3:1 . This means that for approximately every unit of energy consumed (from the mains electricity supply required to operate the heat pump), the heat pump will deliver 3 units of energy to the building in the form of heat. This level of performance can be maintained even when the ambient temperature is as low as 5°C - the temperature of an average winter's day in the UK.
  • the air source heat pump may additional be connected to one or more auxiliary heat sources, such as solar panels, ground source heat pumps and geothermal energy systems.
  • the heat pump, and each fan convector heating unit are preferably provided with plug and socket electrical connectors adapted to enable connection between said heat pump and one or more fan convector heating units, and between respective fan convector heating units.
  • plug and socket electrical connectors combined with the 12V power supply, makes the installation of the fan convector heating units considerably simpler than the installation of existing fan convector based central heating systems.
  • the plug and socket connectors are used simply to link the heat pump to one fan convector heating unit (usually the closest such unit to the heat pump) and then to link each remaining fan convector heating unit in the system to its adjacent units in a "daisy chain" arrangement.
  • a major advantage of this arrangement is that the installation of the entire system can be carried out by a qualified plumber, without the need for an electrician.
  • the accreditation or certification generally required to perform electrical installations (known as "part P” certification in the UK) is not required for 12V "plug and play” installations as described above.
  • the electrical installation of the system can be carried out without the need for any specialist tools.
  • the plumber carrying out the installation would not be required to have any specialist knowledge of the operation of the heat pump - all that is required for the installation is to run pipe work from the heat pump fluid connectors to the fan convector fluid connectors, in the same way as for a conventional central heating system.
  • the present invention therefore preferably provides a heating installation as hereinbefore described comprising a plurality of fan convector heating units arranged in series, wherein each fan convector heating unit in the series is electrically connected to the adjacent fan convector heating unit in the series by means of plug and socket electrical connectors, and wherein the first fan convector heating unit in the series is electrically connected to the heat pump by means of said plug and socket electrical connectors.
  • the fan convector heating units utilised in the heating installation according to the present invention are preferably slimline, down-draft fan convector heating units.
  • Such slimline units are generally slimmer than a single panel radiator and have a width of substantially 86 mm.
  • the use of down-draft fan convector heating units means that cooler air is drawn in through the top of the unit and warmed air is expelled through the base of the unit.
  • the emission of warmed air from the base of the unit, rather than the top, is considered to be more efficient for heat distribution, since the warmed air gently drifts across the floor of the room, thus eliminating the cold drafts often associated with other heat emitting apparatus.
  • the fan convector heating units utilised in the heating installation of the present invention are designed to be installed in same way as a conventional radiator. In particular, there is no need to remove the cover or casing as is required when installing many existing fan convectors. Instead, the fan convector heating units used in the present invention are each provided with a back hanger. During installation, the back hanger is screwed to a wall of the building, the fan convector heating unit is hung on the back hanger, and the chassis of the fan convector heating unit is then screwed to the wall via fixing points at the bottom of the unit.
  • the fan convector heating units used in the present invention are designed to be activated by the heat pump, via the control means, only when the water circulating in the fluid connectors as been sufficiently heated, the fan convector units do not require a low temperature cut-out (LTC) thermostat, as is generally required in existing fan convector heating units. This means that further cost savings can be achieved in the manufacture of the fan convector units employed in the present invention.
  • LTC low temperature cut-out
  • the heating installation of the present invention preferably further comprises a house thermostat in electrical communication with the heat pump, and adapted to activate said heat pump upon the house temperature falling to a pre-determined activation temperature, and to deactivate the heat pump upon the house temperature reaching a pre-determined deactivation temperature.
  • each fan convector heating unit is preferably further provided with a zone room thermostat adapted to switch said fan convector into an ON mode upon the room temperature falling to a pre-determined activation temperature, and to switch said fan convector into an OFF mode upon the room temperature reaching a pre-determined deactivation temperature.
  • the units may optionally also be provided with a manual over-ride switch to enable the unit manually to be switched between ON and OFF modes.
  • BSRIA Building Services Research and Information Association
  • the fan convector heating units utilised in the present invention were shown to use 24% less energy to heat a room, compared with conventional radiators of equivalent size. This figure was found to increase to 31 % when used with lower water temperatures. Accordingly, it is recommended that for maximum energy efficiency savings, the heating installation of the present invention should be operated with lower water temperatures (50 °C).
  • the activation of the heat pump will be controlled by the house thermostat and preferably also a time clock. Once activated, the heat pump will typically run for approximately 3 to 5 minutes to heat up the water before the timed switch activates the 12V power supply to the fan convector heating units.
  • the control means may desirably provide the facility to adjust the time period between activation of the heat pump and activation of the 12V power supply to the fan convector heating units. Once the power supply is activated, each fan convector heating unit switched to its ON mode will be energised.
  • the heat pump is deactivated when the house thermostat's preselected deactivation temperature has been reached. This in turn switches off the fan convector heating units by deactivating the 12V power supply.
  • the heat pump (and hence the 12V power supply and the fan convector heating units) will then cycle in the same way as a conventional boiler, according to temperature variation in the house and the house thermostat settings.
  • the heating installation of the present invention may be adapted to include an indirect hot water storage cylinder in fluid connection with the heat pump coil, for the supply of domestic hot water.
  • the heating installation of the present invention is intended to be supplied as a full central heating package, adapted to suit different house sizes.
  • the installation may be supplied with heat pumps of varying power and with any number of fan convector heating units, preferably in the range of from six to twelve.
  • the scope of the present invention extends to include a modified fan convector heating unit for use in a heating installation as hereinbefore described.
  • a fan convector heating unit for use in a heating installation comprising a heat pump and control means as hereinbefore described, said fan convector heating unit comprising:
  • an electrically driven fan arranged to direct air over said heat exchanger; and - fluid connectors adapted to deliver heated water to said heat exchanger from said heat pump and to return cooled water from said heat exchanger to said heat pump;
  • the electrically driven fan is adapted to be activated by said control means upon receipt of an activating signal from said heat pump.
  • Figure 1 shows a diagrammatic representation of a preferred embodiment of heating installation according to a first aspect of the present invention.
  • Figure 2 shows a perspective internal view of a fan convector heating unit according to a second aspect of the present invention, for use in the heating installation of Figure 1 .
  • the heating installation comprises a heat pump 1 1 arranged to drive a series of six fan convector heating units 12, 13, 14, 15, 16, 17, according to a second aspect of the present invention, as will be described in more detail below with reference to Figure 2.
  • the heat pump 1 1 is provided with flow and return fluid connectors 18, 19, in communication with the heat pump's internal coil (not shown) and to which are connected flow and return pipes 21 , 22 adapted, respectively, to deliver heated water from the heat pump 1 1 to each fan convector heating unit 12-17, and to return cooled water from said units 12-17 to the heat pump 1 1 , via like flow and return fluid connectors 23, 24 on each unit 12-17.
  • the heat pump 1 1 and each heating unit 12-17 are also provided with electrical socket connectors 25, each adapted to receive a plug (not visible in Figure 1 ) of an electrical connection cable 26.
  • the electrical connection cables 26 deliver power from a 12V transformer (forming part of control means 27 housed integrally within the heat pump 1 1 ) to the internal fan (not shown) of each fan convector heating unit 12-17.
  • the heat pump 1 1 is connected to the first fan convector heating unit 12 in the series, which is in turn connected to the second heating unit 13, which is in turn connected to the next unit 14, and so on.
  • This arrangement not only enables the heating installation 10 to be installed by a qualified plumber without the need for an electrician or electrical ("part P") certification, but also allows for the system to be easily adapted to include additional heating units if required.
  • the heat pump 1 1 has integral control means 27 incorporated therewithin, comprising a 12V electrical transformer.
  • the control means 27 also includes a timed switch (not shown) adapted to activate the fan convector heating units 12-17 by enabling the 12V power supply thereto upon the elapse of a predetermined period of time following activation of the heat pump 1 1 .
  • a timed switch (not shown) adapted to activate the fan convector heating units 12-17 by enabling the 12V power supply thereto upon the elapse of a predetermined period of time following activation of the heat pump 1 1 .
  • This arrangement negates the need for a low temperature cut-out (LTC) thermostat as is required in existing fan convector heating unit systems.
  • LTC low temperature cut-out
  • Each fan convector heating unit 12-17 may also be provided with a zone/room thermostat (not shown in Figure 1 ) to provide additional independent control for each unit 12-17.
  • fan convector heating unit 12 for use in the heating installation 10 according to the first aspect of the present invention.
  • the fan convector heating unit 12 is shown in Figure 2 with its cover removed in order to view the internal components.

It should be understood that the fan convector heating unit 12 illustrated in Figure 2 may represent any of the sequence of fan convector heating units 12-17 described above with reference to the heating installation 10.
  • the fan convector heating unit 12 is provided with flow and return fluid connectors 23, 24 for fluid communication with the heat pump 1 1 and adjacent like units 13-17.
  • the fan convector heating unit 12 is also provided with an electrical socket connector 25, for electrical connection to the heat pump 1 1 and adjacent like units 13-17.
  • the fan convector heating unit 12 has a heat exchanger 31 in fluid communication with the flow and return fluid connectors 23, 24.
  • An electrically driven fan assembly 32 is arranged to draw cool air in through an air inlet 33 located near the top of the unit 12, and to direct it over the heat exchanger 31 to an air outlet 34 located at the bottom of the unit 12. Warm air is thus expelled from the bottom of the unit 12 creating a "down-draft" effect as hereinbefore described.
