Improved method of energy-saving heating of buildings

摘要

The method according to the patent ... (Patent Application P 3801199.9) uses, for heating a building, the solar energy occurring in and on the latter as well as waste heat. In this respect, relatively great air quantities are circulated, their movement energy, however, remaining unused. The improved method is characterised in that, by means of the waste air flowing out and/or the fresh air flowing in, electric current is generated via in each case at least one wind wheel arranged in the air flow with an associated generator, with which current hydrogen gas is obtained from water by electrolysis, which gas is used for additional building heating as required. In this way, surplus energy can be transformed in an energy form, namely hydrogen gas, which can be stored in a practically loss-free manner. The new method is suitable in particular for use in relatively small accommodation units, such as single-family and two-family houses.
