Water heaters with tank are suitable solutions for hospitals, sports arenas, hotels, apartment blocks and similar large buildings. The product range covers storage and charge systems which all combine the demand for high-performance, comfort, hygiene and resource-efficient operation. The systems can be combined with a second or multiple DHW storage tanks for optimum tailoring to on-site conditions, available with ready-to-mount piping.
How does a storage water heater work?
A storage water heater operates by releasing hot water from the top of the tank when the hot water tap is turned on. To replace that hot water, cold water enters the bottom of the tank, ensuring that the tank is always full.
Our storage charging systems feature these two functions:
- Storage Charging System - Due to the high-efficiency heating surface of the plate heat exchanger, the ThermoDual® systems obtain low return temperatures in the total operating sequence of a storage recharge, thereby resulting in reduced required volume flow rate. This means economical operation and makes the systems highly suited for application in district heating networks as well as in connection with condensing boilers.
- Anti-legionella System - The Danfoss domestic hot water system ThermoClean® provides an additional effective solution for legionella-free domestic hot water production. ThermoClean® systems operate according to the principles of thermal disinfection, ensuring that the reaction temperature in the system is maintained at a constant temperature of 70°C. This provides effective protection against legionella bacteria in the domestic hot water system.

Until 2014, the apartments in this multi-family building located in the Hamburg suburb of Bergedorf were heated using electrical water heaters and supplied with domestic hot water using electrical instantaneous water heaters. Now, after the renovation, a block heating station in the basement of the building provides heating distributed via flat stations installed in the stairwell and used for decentralized domestic hot water. Tenants were able to stay in their apartments throughout the renovation process.

Visitors to Hamburg’s Henriette-Herz-Ring who let their gaze drift upward will discover two shipping containers on the roof of the apartment building. They are the visible result of an innovative planning initiative to replace inefficient gas boilers with Danfoss flat stations. The highlight of this renovation: residents did not have to vacate their apartments.
