Description

The present invention relates to a heating and service water system, consisting of a hot water storage module, comprising a domestic hot water tank, in particular a stratified tank according to the generic term of claim 1.

Heating and industrial water systems from type in question are known from the prior art and are considered a complete unit that includes a hot water, in particular Stratified storage, and includes a heater, sold and transported to the installation site. With a total weight of - depending on Size - about 100 kg, for example for a one to two family house, the transport is only with appropriate Aids easily possible. With difficult entry conditions such as. There are narrow or steep stairs the weight and bulk of the system, risk of injury and the risk of damage of the device.

It is an object of the present invention To provide heating and domestic water system, which is easy transport and even in confined spaces can be spent at the installation site.

This task is performed by a heating and hot water system according to claim 1 solved.

In particular, it does the job solved, that at a heating and service water system, consisting of a water storage module, comprising a domestic hot water tank, in particular a stratified tank, with a cold water inlet, a process water tap, a from the lower area of the same lead the cold water drain as well one leading into the upper area of the stratified storage and hot water pipe connectable to the cold water outlet, and consisting of a heating module with heater, heating circuit pump, pre and Return line and a heat exchanger through which heat exchange with a through cold water drain, hot water pipe and stratified storage formed hot water circuit takes place, both modules mentioned solvable are interconnected.

A basic idea of the present The invention consists in two modules by a corresponding to give meaningful constructive design equal weight. A modular structure with two compact, balanced units is in that everyone Functional elements can be integrated into the heating module. The stratified storage module consists only of an insulated storage container, whereby an easy way is provided for connecting the two modules. Through this division easy transport to the installation site is made possible in two modules. In particular, separate transport to the installation site can also be carried out be carried out easily and quickly in the basement or, for example, attic.

According to the invention, this is advantageous Heating module and the hot water storage module via one each in the cold water fume cupboard (from the stratified storage tank) and the hot water pipe (to the stratified storage tank) arranged pipe connection releasable connected with each other. This is an easy way to connect the necessary hydraulic connections. The pipe connections can be interpreted so that they too ensure a stable coupling of both modules at the same time.

Another advantage is that the two Modules on top of each other arranged and the pipe connections preferably a common one Side of the interconnected modules. In order to is an elevated one stability the connection ensures on the other hand, there is no longer a need for long-term protection lining pipe guides to the junction of both modules. Furthermore, the space requirement a footprint the heating and service water system is minimized by this arrangement and therefore an initial assembly as well as a subsequent installation under almost all spatial Conditions.

Alternatively, with the help a base for which at least the upper, usually heating module, and flexible Pipe connections also a side by side arrangement possible.

Both modules preferably have about the same weight. Especially with a weight of one Modules of up to approx. 50 kg are each of the modules by two people effortlessly manageable, i.e. even under cramped conditions at the installation site be brought.

Another advantage is if the heating module is spatially is arranged above the hot water storage module and both modules have geometrically coordinated outer panels. On the one hand, this becomes the footprint minimized with the advantages mentioned, on the other hand, the device is compact Lent appearance. In this way, the heating module also has side panels Cladding panels mounted to the same width as the one below to achieve arranged hot water storage module. In case of a Installation next to each other is at least for what is normally below Module provided a cover, the game for the required pipe connections leaves. A such a cover can be, for example, a worktop.

It is advantageous if at least two, but preferably a maximum of four, releasable connecting elements are provided for rigid coupling of the two modules between the hot water storage module and the heating module. These ensure a firm connection between the two modules, which means that the Delivery could take place in the assembled state.

The connecting elements are preferred one common side of the interconnected modules assigned. This makes them easily accessible, thereby separating them Just solve of these a maximum of four connecting elements and e.g. two union nuts a complete separation of the pipe connections of the stratified storage tank of the modules.

The connecting elements preferably have at least a, in particular essentially horizontal, guidance to Installation of the heating module on or on the hot water storage module on. After loosening the connecting elements can thereby the heating module from a Securing position e.g. in a so-called keyhole contour be pushed in front. The heating module can then be lifted off and both modules are transported to the installation site. Such one horizontal or vertical alignment next to each other therefore enables problem-free installation and disassembly of both modules.

The connecting elements particularly preferably have at least one stop for positioning the heating module in a fixed end and / or snap position. So that will a tedious shifting of the heating module over or on the hot water storage module is unnecessary until a final one and a perfect fit Position is found. The connecting elements provide at least partially a secure end and rest position.

It is also preferred if the Fasteners for fixing the heating module have on the hot water storage module. Here, e.g. in a End or rest position a defined and secured fixation of the two modules on or above each other ensured.

It is particularly preferred if the fasteners are screw or toggle fasteners. In order to are e.g. in the front area as on the back of the heating module to loosen two screw or alternatively toggle fasteners. By another separation Finally, two pipe connections on the stratified storage tank are hot water storage modules and heating module can be handled separately.

Further embodiments of the invention result itself from the subclaims.
