Definitions

  • the present invention relates to a heating apparatus for heating water for space heating, comprising at least two substantially identical heating units which each comprise a heat source and at least one heat exchanger thermally coupled to the heat source.
  • Such heating apparatuses are known from NL-A-1003624.
  • This relates to a number of substantially identical heating units which are combined subject to the output required from the heating apparatus.
  • This form of modular construction results in a simplification of production, design and logistics.
  • the heating device known from this publication is only suitable for heating water for a single purpose, in this case space heating.
  • the present invention has for its object to provide such a heating apparatus which is also suitable for simultaneous indirect heating of tap water and wherein the advantages of a modular construction are retained.
  • the heating units are divided into a first group for space heating and into a second group for tap water heating, and in that the heating apparatus comprises a regulating device for regulating the temperature of the heating units of the first group and the temperature of the heating units of the second group independently of each other.
  • heating apparatuses for heating tap water and for heating water for the purpose of space heating are of course per se known. Simultaneously heating water to different temperatures for the purpose of tap water and space heating is however not possible herewith.
  • the heating apparatus comprises a regulating device for regulating the temperature of the heating units of the first group and the temperature of the heating units of the second group independently of each other, an optimization can be obtained for both purposes, in this case space heating and tap water heating.
  • the efficiency of the total apparatus is hereby greatly increased.
  • This regulation has the result that the temperature of the units associated with diverse groups can differ considerably. This can result in situations in which the warmer unit supplies so much heat to an adjoining unit forming part of another group and having a lower temperature that the water present in the colder unit will begin to boil.
  • heating units forming part of the first group are thermally insulated relative to the heating units forming part of the second group.
  • At least one of the heating units associated with the first group is adapted to selectively heat water for heating tap water or to heat water for space heating. This measure provides the option of temporarily increasing the capacity of the heating device for space heating, for instance during heating of an office building after the weekend.
  • the regulating device is adapted to assign priority to the demand for water for tap water heating over the demand for water for space heating. It is here also the case that for the space heating a low output is usually required for a long time, while the provision of tap water is maintained by a buffer supply which is heated in a short time with a great output.
  • the heating units are disposed adjacently of each other and each of the heating units comprises two heat exchangers disposed on either side of the heat source. This results in a space-saving and flexible arrangement.
  • the heat exchangers of adjacent heating units forming part of the same group are combined. This saves space.
  • a secondary heat exchanger is connected between the heat exchangers of the units associated with the first group and the tap water circuit.
  • FIG. 1 shows the diagram of a heating apparatus designated in its entirety with "1".
  • the heating apparatus is formed by a number of substantially identical heating units 2 disposed adjacently of each other.
  • Each heating unit 2 is formed by a heat source in the form of a burner 3 and a heat exchanger 4 arranged on either side thereof.
  • the heating units 2 are divided into different groups; i.e. a first group, shown on the right in figure 1, which is adapted for space heating, and the second group, placed on the left in figure 1, which is adapted to heat tap water.
  • heat exchangers 4 of the right-hand group of heating units are connected to a water circuit 5 which forms part of a usual central heating installation.
  • Gas, or possibly another fuel, is herein supplied by means of a gas feed pipe 6 to burners 3, which heat the heating units in question.
  • a regulating device 7 is received in pipe 6.
  • a plurality of regulators is of course possible here, such as with thermostats which are arranged in diverse spaces, and combinations hereof.
  • the left-hand part of the array of heating units 4 is connected to a circulation water pipe system 8.
  • This circulation water pipe system 8 leads to a secondary heat exchanger 9, through the other side of which runs the tap water pipe system 10.
  • This construction provides the option of manufacturing the heat exchangers 4 from aluminium or an alloy containing aluminium, which is attractive from a production viewpoint. Since tap water may not run directly through such heat exchangers, separate additional heat exchangers 9, manufactured from for instance copper, must be applied.
  • the burners 3 in question are connected to a gas feed pipe 11, in which is received a regulating device 12 which is controlled by means of classic control parameters.
  • Figure 3 shows a final configuration which otherwise corresponds with the configuration shown in figure 2, but wherein the two left-hand heating units 2 can be used selectively for space heating or for tap water heating.
  • the choice hereof depends on the demand for both types of heating, wherein normally these left-hand units are connected for tap water heating, but when the demand for space heating is greater than can be generated by the right-hand heating units, the space heating capacity can be increased temporarily, albeit by decreasing the tap water heating capacity.
  • a three-way valve 15 which is controlled by a central control device 14, which otherwise also controls regulating devices 7 and 12.
  • the demand for tap water however generally has a higher priority that the demand for space heating.
