System for heating two mutually separated liquids

摘要

The invention relates to a system for heating two mutually separated liquids, wherein a first liquid is intended for heating a building and wherein the second liquid is tap water, which system comprises:
- a device for heating the first liquid, the device comprising:
- a housing with an air feed, a fuel feed and a flue gas discharge;
- a burner disposed in the housing for combusting fuel and air while releasing flue gases;
- a first heat exchanger for transferring heat from the flue gases to the first liquid;
- a second heat exchanger for transferring residual heat from the flue gases to the tap water;
- a third heat exchanger for transferring heat from the first liquid to the tap water; and
- a reservoir for storing tap water which is connected via a first conduit debouching in an upper part of the reservoir to the third heat exchanger, wherein the reservoir is connected on a lower part via a second conduit to the second heat exchanger.
