Definitions
- This invention relates to an improvement of a combined central-heating and water-heating boiler.
- Both types can be arranged adjacent to the central-heating boiler and, in principle, in both cases, elsewhere (i.e. in the central-heating boiler) water is heated for a specific purpose, namely the heating of space, the heated water is passed through radiators, and the heated water also heats water that is being supplied for a different purpose (domestic use).
- NL-A-8 801 761 discloses a combined central-heating and water-heating boiler and proposes to replace the single pump and the distributor or re-set valve by two pumps, one pump serving to supply the central-heating water circuit and the other pump serving to direct the hot central-heating water to a boiler tank or tap vessel of a sanitary water appliance, while only one of the two pumps is operative at any given time.
- the above-mentioned application proposes a double-pump wherein the two pumps are joined by a coupling member in which is provided a branched passage with a two-way valve via which the pumps are connected with an external pipe connection. Under the influence of the instantaneous flow, the two-way valve automatically takes up a position in which the circuit that is switched off is effectively isolated.
- the object of the invention is to provide a further constructional simplification of a combined central-heating and water-heating boiler of the above-described type, in which a coupling member and a two-way valve are superfluous.
- the boiler body comprises a heat exchanger formed from aluminum or an aluminum alloy
- this heat exchanger comprising a flue and a central-heating water section comprising a serpentine or zig-zag central-heating water channel, the flue and the water section being separated by a dividing wall
- spaced-apart pairs of connections for the suction and delivery sides of two pumps are provided in the water section of the heat exchanger, while in each pair of connections the suction and delivery connections of the pumps are separated from each other by partitions.
- central-heating water can be directed either into the space heating circuit or to the boiler or tap vessel of the sanitary water appliance.
- a distributor or reset valve is not necessary and in particular when use is made of a pump having the suction opening and the delivery opening in the same end face, supply and drain pipes from the pumps to the heat exchanger can be omitted. The operations for assembling such a compact combined boiler are thus reduced to a minimum.
- the pumps can be connected, from the flue gas side of the flat boiler, to the water side at the discharge end of the flue section, where they take the place of heat-absorbing projections, a lesser number of which are required in that area on account of the volume reduction of cooling flue gases.
- the above-mentioned features can also be used in a normal central-heating boiler without sanitary water applicance. In that case, only one pump is connected in the manner described above. If such an appliance is connected at a later time, the second pump can be connected at that time.
- Fig. 1 shows a section through the water section of a heat exchanger 1 of a combined central-heating and water-heating boiler in which the water section comprises a zig-zag channel system 2.
- partitions 3 and 4 have been arranged in the zig-zag channel system 2 in a suitable manner and on opposite sides of these partitions, connection points 3p, 3z and 4p, 4z, respectively, have been provided for the direct connection of two pumps 5 and 6, respectively.
- the pump 5 is switched on and pump 6 is switched off.
- the water in the heat exchanger 1 is then forced via the opening 3z, the pump 5 and the delivery connection 3p into the heat exchanger compartment 9, closed off by partition 3, and directed via outlet opening 10 from the heat exchanger 1 to the boiler or tap vessel 7, where it heats the sanitary water.
- pump 5 is switched off and pump 6 is switched on.
- the water in the heat exchanger 1 is then forced via the opening 4z, pump 6 and the delivery connection 4p into the heat exchanger compartment 11, closed off by partition 4, and directed via outlet aperture 12 from the heat exchanger 1 to the space heater 13, where it heats the space to be heated.
- non-return valves may be provided, which close when the associated pump is not in operation.
- Fig. 2 is a side elevation of the apparatus, showing that the burner 14 is connected direct to flue 15 and that, from the side of the flue 15, the pumps 5,6 are connected direct to the water section 16 of the heat exchanger 1.
- Fig. 3 shows the burner space 17 and it can be clearly seen that the pumps 5 and 6, which are connected direct to the water section 16 of the heat exchanger 1, are arranged at the discharge end 18 of flue 15, where they take the place of heat-absorbing projections (not shown), a lesser number of which are required in that area because of the volume reduction of cooling flue gases.
