The invention relates to a heating system or a heating system one or more heat generators, e.g. B. condensing boilers, boilers, Therme etc., using the heat for one or more heating circuits, as well as egg One or more hot water tanks via one or more hot water memory (buffer memory) that is heated by the heat generator and that from the heating water through a heat transfer material (if necessary) is separated, otherwise one or more hot water storage tanks can also be used heat transfer surface can be used.  

Such heating systems or heating systems are in the home Rich known for a long time, the heating circuit supply and return lines as well includes all types of (room) radiators and the hot water tank regular for domestic water heating for bathtubs, showers, hot water and hot water storage tank separated from each other and the heating of Process water in the water storage tank takes priority over heating the heating circle. The heating circuit is only supplied with heat when that Hot water has reached the desired temperature.

Is a correspondingly high temperature level in the hot water tank, which z. B. has a process water volume of approximately 100 liters upwards, reached, the hot water heating is interrupted and the heat supply heating circuit can begin.

The heat generator is usually a gas or oil heating boiler, one Therme or a condensing boiler with its own small storage. A sol cher heat generator has a burner to which fuel is supplied and via a boiler or storage tank with a, depending on the type, water volum has about 20 to 50 liters. To heat the heating circuit is too next the water volume of the boiler of the heat generator is heated, and so as soon as this water has reached the desired temperature, the heater becomes generation stopped, d. H. in the case of a gas or oil burner, the burner is switched off ners. Then the water warmed up in the boiler is recurring Pumped heating circuit, the water cooled by the heating flow from the Returns the heating circuit to the boiler. It is due to closed Thermostat valves of the radiators, however, rarely a desired circulation of the Water.

Due to the relatively small boiler water content and the associated those with a lower heat storage capacity compared to the water consumption volume or heat requirement of the heating circuit cools the water in the boiler selspeicher very quickly and a new heat generation / burning phase must be started. Starting or switching off the heat generator is practiced referred to as clocking. With conventional heating systems  30,000 to 40,000 cycles are necessary annually to the heating circuit and To supply domestic water - which places a considerable burden on the heat generator by constantly starting up and before starting up a boiler - in the standstill phase of the boiler is cooled by the flue gas duct must reheating more energy. Also at the ständi a lot of fuel and (start-up) electricity used up - comparable to a car that is operated in city mode the highway at constant speed less consumption and significant has less pollution.

Due to the large number of clockings, the conventional devices are noticeable Chen exposed to loads, making the heaters maintenance-intensive and expensive are.

It would be conceivable to increase the boiler content of the heat generator - what however, would be very expensive and have problems with the structural conditions would bring.

The aim of the present invention is to provide heating and hot water energy to reduce the consumption of a heating system - while maintaining the same level of comfort Reduce wear, increase ease of maintenance and electricity reduce consumption. This leads to a noticeable reduction in emissions (Greenhouse effect, ozone), especially when starting up and shutting down the system, because the thermal combustion has not yet been clearly clarified here.

Furthermore, the invention is intended to achieve this aim without the disadvantages that the Adhere to the state of the art in heating systems, to be adopted. There at the measures for implementing the invention should be made so simple be that every heating fitter undertakes such a new, retrofitting or retrofitting men can.

The task is solved according to the invention with a heating system, the egg NEN heat generator that buffers or heats up a hot water tank includes and further means (z. B. heat exchanger) for feeding the warm water buffer storage of heated medium (water) in the respective heating circuit or to the domestic hot water tank.  

The invention is based on the knowledge that with a simple measure took, namely with the controlled injection of the heat potential of the Heat generator in a heat buffer storage (and possibly in separate heating circuits and hot water circuits) the number of cycles of a heating system from 30,000 to 40,000 per year reduced to 1,500 to 2,500 cycles per year can be.

The prototype of the heating system according to the invention proved itself in practical use so far very economical. The low maintenance is especially important achieved by the small load on the oil or gas boiler, which the stands still most of the year.

The significant reduction in pollutant emissions can be achieved because by operating a few cycles of the heat generator over one large period during the warming phase works in the optimal range.

The heating system is thus market and commercial use Cher individual units such as heat generators, heat storage, hot water storage cher, mixer, pumps, pipes, etc. considerably more economical, durable, function spreader, maintenance-independent and significantly less polluting.

In the following the invention with reference to a in drawings presented embodiment explained in more detail.

Description process

The buffer tank ( 2 ) gives the heated amount of water in the flow distributor ( 5 ), from where the individual heating circuits ( 8 ) are operated. This is done explicitly via a mixer ( 3-4- way) ( 7 ) which has a mixer motor. This mixer motor is controlled by the flow sensor (VF), which is located behind the feed pump ( 4 ). The mixer motor is also controlled by the outside sensor (AF). The mixer motor then regulates the feed pump ( 4 ) with these two values. In summer operation, when no heating is required, the feed pumps are out of operation and the mixer motor sets the mixer to "short circuit", ie flow distributor ( 5 ) to return distributor ( 6 ). In heating mode, the mixer ( 7 ) regulates the required flow temperature as described. A temperature limiter (TB) is installed in underfloor heating. The feed pumps ( 4 ) therefore take enough hot water from the buffer tank ( 2 ) until the temperature sensor / adjuster (T) reports to the boiler that the hot water temperature for the heating circuits has fallen below. This message is received by the heat generator ( 1 ). There is a burning phase, in the course of which the buffer store ( 2 ) is recharged to a predetermined temperature. When this temperature is reached, the temperature sensor (T) reports "temperature reached" to the heat generator and the burning phase is ended. The use of the check valve (RV) behind the feed pump ( 4 ) to the buffer tank ( 2 ) ensures that no warm water can flow back into the boiler. The heating circuit is operated again from the buffer store ( 2 ) until the next heating phase of the heat generator ( 1 ).

The supply of the domestic hot water tank is analogous. Here, too, the temperature sensor (T) via the feed pump ( 4 ) requests heating water to heat the process water when the required process water temperature is not reached.

All commercially available storage tanks are used as buffer and process water storage tanks possible. Sufficient dimensioning should be used for the buffer tank be respected.

If another energy source ( 9 ) is integrated, regardless of whether solar, wood, etc., the connection is made analogously to the heat generator, also with feed pump and check valve. To secure the buffer storage, the feed pump ( 4 ) is switched off from the energy source ( 9 ) to the buffer storage when the permissible storage temperature is exceeded.
