  • the heating device has through the integration of a sanitary water heat exchanger in the Flue gas discharge duct of the hot water heat exchanger Advantage of a very compact structure. You also get a very wide performance range, which leads to cheap Way receives a reduction in the number of types. Due to the interchangeability of the flue gas duct of the Hot water heat exchanger creates the possibility of a condensing heater, a non-condensing Heater without a fireplace or one on to build a chimney-bound heater.
  • the water-carrying components are preferably in a plug-in technology to simplify assembly executed.
  • the housing is cheap simply constructed from sheet steel, making electronic Circuits protected against the ingress of dust and water can be accommodated.
  • the Heating unit the following parts: an atmospheric Gas burner, a hot water heat exchanger with one integrated, upstream combustion chamber and one downstream flue gas discharge, a cylindrical Housing, a base body with an integrated Sanitary water heat exchanger, means for the supply of Air and means for the supply of hot water and Sanitary water in a pluggable version.
  • the heating unit has within the flue gas discharge of the hot water transmitter an integrated sanitary water heat exchanger.
  • the whole The heating unit is constructed with a central cylinder arranged cylindrical burner by a spiral is surrounded by a smooth tube. Behind - or with vertical Structure under - the burner is the sanitary water heat exchanger attached within a housing so that water in it even with heating operation the associated comfort is kept warm.
  • the whole Outside air flows around the heating unit in a housing.
  • the layered structure gives you one from the inside decreasing temperature gradients, whereby Heat losses can be avoided to a high degree and a high one Operational safety regarding gas leaks is created.
  • a 2- or 3-stage hot water heat exchanger is suitable, its first stage from a smooth tube with closely spaced coils to accommodate Radiant heat consists, and the second stage of one finned tube to absorb the convection heat Combustion gases exist.
  • the connections of the hot water heat exchanger are pluggable in the mounting direction designed to ensure easy assembly. This means that the hot water heat exchanger can also be used by the end user with different number of turns of finned tube to adjust the power that Flue gas temperature, etc. can be replaced.
  • a mounting plate for the burner can be designed in this way be that with no changes burner different diameters and lengths can be installed can.
  • a heating device 1 is shown with a heating unit 21, a control unit 22, one hydraulic unit 23, a connection unit 24 and a storage unit 12 attached to the heating side.
  • a flue gas discharge and air supply connection 25 is connected to the Cover of the heating unit 21 connected and can be modular against connections of different diameters and separated air / Flue gas connections are replaced.
  • the bottom surface 26 of the unit remains with the different types of heating device always the same, the depth 27 being due to installation in front of a wall or a suspension on a wall is coordinated, preferably is less than 280 mm.
  • the control unit 22 is on the front Insertable guide rails.
  • the ones directed to the front Operating and display elements are either with a Baffle connected or in a separate unit brought together, directly or via a cable is plugged in connected to a basic control unit.
  • a Base plate 31 comprises a flue gas duct 40, one Flue gas connection 41 and a housing 42 of a sanitary water heat exchanger 30th
  • the sanitary water heat exchanger 30 comprises one Heat exchanger coil 43, a flange 44 with a integrated flow guide and connections 45 for Heating and sanitary water.
  • the sanitary water heat exchanger 30 is in the housing 42 of the Bottom plugged in and with one not shown 0-ring sealed and in a not shown mounting bracket fixed.
  • the connections 45 are preferably designed as a plug-in system.
  • a helical hot water heat exchanger 32 consists of a smooth tube 46, one with no closer Ribs shown tube 47 and a so connected pipe fitting 48 with a Hot water supply connector 49, where hot water in the Heat exchanger 32 flows, and a hot water discharge connector 50 where hot water from the Heat exchanger 32 flows.
  • the smooth tube 46 serves to absorb the radiant heat and guiding the flue gases while the finned pipe 47 serves to absorb the convection heat.
  • the outer wall of the heating unit 21 consists of a Double cylinder 34 with an inner cylinder 51, one Insulation 52 and, if not installed in a housing takes place, an outer cylinder 53 for mechanical protection the insulation.
  • a lid 36 is preferably water-cooled, though alternatively, passive heat insulation is also used can be.
  • a viewing window 54 is on the cover 36 Fasteners, a bushing 55 for the Feed connector, a flange 56 for attaching the Brenner and a ventilation unit 37 as well Mounting rails 57 for installing the device appropriate.
