Abstract

The invention relates to a system for partitioning a pressurized water heating tank using two or several heat-insulating spaces serially connected to one another and framed in a heat insulating tank. According to the invention, the system comprises a first module having an external orifice () wherethrough water gets in, at the bottom part, upon the opening of a discharge valve (), the water getting out through an orifice () located at the outlet of the last module, at the top part thereof, the water heating process starting with the water entering the first module, where a power of up to 60% of the total power of the heating system can be used, the remainder being divided between the other modules, within the modules the heating being carried out by various methods: coils, combustion tubes, electrodes, resistors, the heater being necessarily positioned at the bottom part of the module and the water flow between the modules taking place between some partition walls () thereof, which are some rigid parallel heat-insulating structures () named a main wall () and a secondary wall (), the said structures () sealing up to 95% of the total wall surface while leaving the rest uncovered at the opposing part of the other one, the tank operating position being either horizontal or vertical, the entering water moving sinusoidally towards the outlet, in both cases the main wall sealing the bottom part of the modules while leaving the top part free, the secondary wall sealing the top part of the modules while leaving the bottom part free, so that the distance between these walls is not smaller than the diameter of the orifice wherethrough water enters the tank and is intended to grow accordingly, as the number of modules in use grows.
