Title: Hot water preparation plant
Inventor: LAING KARSTEN
IPC: F24D17/00
Filed: 1998-05-20
Abstract: Two accumulator vessels (9,13) are each divided by a division area (10,14) into a cooler and a warmer area. The cooler areas of the vessels communicate with each other via a conduit which also contains the cold water distributor conduit (1). The cold water content of the two accumulator vessels is half as big as the accumulator volume of the two vessels. The water content of the cooler area (9B,13B) is fed by the pressure of the pump from one accumulator vessel to the other, whilst back delivery occurs via suitable devices. The circulating pump (12) is reversible. The back feed of the cold water content of the accumulator occurs via displaceable walls (14) which, so long as the pump is not running, are moved to their end position by springs (11,15).
