Abstract (en)

[origin: EP0268023A2] Behind a central heating boiler (1) there is an ancillary water space (4), which is divided by a barrier rib (11) into an upper feed area (12), through which hot water flows, and a lower return area (13), through which cooler return water flows. When required, hot feed water is fed into the return area (13) by a controllable device (16). Drops below the condensation point are avoided. <IMAGE>
