Benefits of technology
[0015] The aim of the invention is, now, to avoid the abovementioned disadvantages.
[0016] In order to meet this aim, an installation of the type as described in the first paragraph is now provided, which installation according to the invention is characterised in that a vent pipe is connected to at least one of the said pipes. By removing vapour bubbles and air bubbles via this (these) vent pipe(s) the abovementioned disadvantages are avoided and the abovementioned aim is met.
Problems solved by technology
One problem that arises in such an installation is the occurrence of vapour bubbles and air bubbles in the various components of the installation.
These bubbles can disturb the flow of water through the installation and thus, for example, have a severe adverse effect on the functioning of measurement systems that function on the basis of an undisturbed uniform flow of water.
The pump will consequently no longer deliver a uniform stream of water, as a result of which the measurability of the pumping process is adversely affected.
As a result of the turbulent movements of the water in the pump some of these gases can be liberated and form air bubbles, as a result of which the operation of the pump is impaired.
If the flow ceases, air and vapour bubbles present in the pipes can deposit on the wall of the pipe and thus disturb a further flow of water.
This introduction of fresh water frequently gives rise to turbulence, as a result of which air can be entrapped in the water, which then can lead to the problems indicated above in other parts of the installation

Embodiment Construction
[0028]FIG. 1 shows an installation from the state of the art. This installation is provided with a cold water reservoir 10, a heating unit 11, a cold water pipe 12 between the cold water reservoir 10 and the heating unit 11, a draw-off point 13 for drawing off hot water, a hot water pipe 14 between the heating unit 11 and the draw-off point 13, and a pump 15. The pump 15 provides for the flow of water from the cold water reservoir 10 through the cold water pipe 12, the heating unit 11 and the hot water pipe 14 to the draw-off point 13.
[0029] The heating unit 11 is filled with a liquid (generally water) that is kept at a predetermined temperature (just below 100 degrees C) by an electric heating element 17. This element is actuated in a known manner by a controller 21 on the basis of signals from a thermostat (not shown). This is assumed to be known to those skilled in the art.
[0030] The level of the water in the reservoir 10 can, for example, be controlled by a level sensor 18 tha...

Disclosed is an installation for the preparation of hot water. The installation includes a cold water reservoir, a heating unit, a cold water pipe between the cold water reservoir and the heating unit, a draw-off point for drawing off hot water, a hot water pipe between the heating unit and the draw-off point and a pump for making water flow from the cold water reservoir through the cold water pipe, the heating unit and the hot water pipe to the draw-off point. A vent pipe is connected to at least one of the said pipes.
Description
FIELD OF THE INVENTION [0001] The invention relates to an installation for the preparation of hot water, comprising: [0002] a cold water reservoir, [0003] a heating unit, [0004] a cold water pipe between the cold water reservoir and the heating unit, [0005] a draw-off point for drawing off hot water, [0006] a hot water pipe between the heating unit and the draw-off point, [0007] a pump for making water flow from the cold water reservoir through the cold water pipe, the heating unit and the hot water pipe to the draw-off point. STATE OF THE ART [0008] An installation of this type is described in EP 0 771 542. In this installation the pump is installed in the cold water pipe between the cold water reservoir and the heating unit, However, the invention yet to be described is not restricted to this and also covers installations where the pump has been installed in the hot water pipe between the heating unit and the draw-off point. [0009] One problem that arises in such an installation i...
