- the water heating element 10 is mounted here in the bottom element 2a, preferably such that the top of the heating element 10 is level with the top of the bottom element 2a of the reservoir. This facilitates to assembly of the reservoir 1.
- the inlet 4 of the reservoir 1 is associated with a water inlet distributor 4a arranged below the heating element 10 and having one or more water distributing openings allowing the inflow of water in a generally radial direction into the reservoir 1.
- Figure 12 depicts a schematic flow scheme of an apparatus according to an embodiment of the invention and an associated boiling water tap.
- this apparatus of figure 12 is designed solely for dispensing boiling water, preferably for use with a boiling water tap, e.g. mounted at a kitchen sink.

- the reservoir 101 is preferably embodied as discussed with reference to figures 1-11 , e.g. including one or more of the preferred features thereof.
- the reservoir 101 is completely filled with water.
- the water in the reservoir 101 is preferably heated to a temperature above the atmospheric boiling point of water, e.g. to 110 - 106 °C. Due to this relative low overheated water the steam production reaching atmospheric pressure is reduced. For example, when the temperature is 115 °C, per litre water one litre of steam is formed after expansion. At 105°C, this is only 30%. In other words, steam formation reduces a factor 3.
- an outlet pipe element 109 is provided that is connected to the outlet 103, which pipe element 109 here is of a U-shape and bends upwards towards the top of the pressure vessel 101.

- the switch 151 is also visible in fig. 16a .
- valves 140, 141 e.g. electromagnetic valves, are provided in parallel.
- the parallel valves 140, 141 allow a user of the tap 150 to choose between two volumetric flows depending on the application. For instance, if a small volumetric flow is required, e.g. to fill a cup, only one of the valves is opened, but in case a larger volume flow is required, e.g. to fill a tea kettle or cooking pan, both valves are opened.
- the apparatus includes control electronics for the parallel valves 140, 141 in the boiling water pipe 110,111 such that first operation of the switch on the tap 150 cause one valve 140 to open, and such that the second valve 141 also opens when the switch is operated beyond a predetermined time, e.g. after operating, e.g. depressing, the switch for more than 10 seconds.
- a filter 142 As is preferred in the boiling water pipe 110, 111 leading to the tap 150, outside of the reservoir 101, a filter 142, preferably exchangeable, is provided to filter the boiling water.
- the advantage of providing this filter 142 outside the pressure vessel reservoir 101 is that the filter 142 can be easily replaced by a non-technically skilled person.

- the tubular wall portion 148 may be a tube with one open end and one closed end, said closed end being inserted through an opening of the reservoir 101 and then attaching the open end to the wall of the reservoir by for instance welding.
- a second temperature sensor 107 is mounted in this embodiment to the outside of the wall of the reservoir 101 to measure a water temperature in the reservoir at the top.
- the electric water heating element 104 is controlled by an electronic control system 155 on the basis of the one or more temperature sensors 106, 107, preferably with a suitable thermostat.

These components preferably at least include a temperature sensor (here sensor 106) for measuring a water temperature in the reservoir, preferably near or just above the heater, and an electrical thermostat 106b coupled to said temperature sensor for controlling the electric heater.
- a temperature sensor here sensor 106
- an electrical thermostat 106b coupled to said temperature sensor for controlling the electric heater.
- the support member 182 also includes a electric mains connector, e.g. with electric cable 184, as well as an electric cable 185 to connect to a boiling water tap (150).
- a electric mains connector e.g. with electric cable 184
- an electric cable 185 to connect to a boiling water tap (150).
- the apparatus comprises an assembly of one or more valves, here including mixing valve 116, and associated water conduits, in this example both flexible and non-flexible.
- the apparatus here comprises an upper support member 190 mounted above the reservoir 101, said upper support member 190 supporting the one or more valves, as is preferred at least mixing valve 116 when present in the apparatus.
- the upper support member 190 is substantially plate-shaped.
- the mixing valve 116 is resting on top of said upper support member 190, as is preferred in a depression 190a formed in the upper support member.
- the mixing valve 116 is a thermostatic valve and has a temperature adjust knob to adjust the temperature of the hot water, e.g. between 50 and 70 °C.
- the knob is accessible at the front of the apparatus.
- a cover member 191 is mounted over the upper support member.
- a heat exchanger 200 is arranged between the pipe 115 connecting the reservoir outlet 103 to the mixing valve 116 on the one hand and the pipe 112 connecting the water mains pipe connector to the water inlet 102 on the other hand, such that water from the reservoir 101 to the mixing valve 116 is cooled, preferably to below 100 °C, and the heat is transferred to the water flowing to the inlet 102 without water being mixed in the heat exchanger. It will be appreciated that this solution is most advantageous when the mixing valve 116 is housed within the outer housing of the apparatus, so that also said heat exchanger can be fitted within said outer housing too.
- a set of spring operable balls 270 is shown which allow stepwise height adjustment of the tap 271.
- This type of height adjustment is applicable in any type of tap, preferably a hot water tap, more preferably a hot water tap suitable to be used in an apparatus according to one or more aspects of the present invention.
