Very environmentally friendly heating by means of compressed air. Absolutely no waste gases, absolutely no harmful substances. The pressure cylinder compresses the air (gas) by means of weight, as a result of which once the installation has been purchased no more electricity, coal, wood, gas or oil are required, that is to say full water heating absolutely free, completely independent of any weather and anywhere in the world. Even the "pumping-over" into a storage boiler can, if necessary, be carried out without great energy consumption simply by means of falling and with rising heating. By removing the heated domestic water (see schematic diagram), the pressure is reduced - new air being sucked in - and the compression process can start heating the water again from the beginning. In the case of a plurality of bundled cylinders operating at different times, it is thus possible to obtain hot water round the clock, independently of all external influences.
