Gas boilers with water heating in an external reservoir operate in the same way as boilers for heating only. Because hot water is stored in an indirect reservoir, water can be continuously supplied to more consumption places. The boiler heats water from the reservoir as required and without jumping processes. A three way valve inside the boiler unit alternatively heats the heating system and utility water in the reservoir.
Our wide range of external reservoirs can produce relatively high amounts of hot water to satisfy households as well as demanding clients requiring high comfort. A wall boiler unit is mounted on a wall directly above the reservoir.
