With Danfoss systems you never need to worry about legionella or insufficient or cold water in the bathrooms. Our domestic hot water solutions include water heaters that can be connected to multiple tanks as well as storage and charge systems, hot water valves that prevent legionella, temperature controllers and self-limiting heating cables that are used for temperature maintenance. When used together, these combine the demand for high performance, comfort, hygiene and resource efficient operation – even during peak loads.
Production of hot water is done by one of our water heaters. These can be equipped with one or more storage tanks to provide enough hot water at peak loads. They can also be equipped with a storage charging principle. They meet hygienic, safety and temperature requirements and can be connected to different energy sources. Adding hot water valves and temperature controllers help prevent legionella. All together a high performance, comfortable, hygienic and resource efficient production of DHW is achieved.
The hot water is then distributed to the water tap points. In most cases the size of the building requires a series of risers circulating the hot water. Our Thermal balancing valves ensure the proper hydronic balance that avoids long waiting times. As these control the water temperature they also avoid too hot water causing lime, corrosion and energy inefficiency. Normally these valves are set to a temperature that avoids legionella to grow.
The thermal balancing valves can be equipped with thermostatic or electronic disinfection modules, allowing periodic flushing of the system to kill the legionella bacteria. The electronic temperature registration system monitors all the temperatures and initiates the safe and energy efficient disinfection cycle. It also stores the temperature data for logging purposes. The electronic controller can be easy accessed on mobile devices using Wi-Fi or be integrated into Building Management Systems (BMS) for remote control, monitoring and alarm purposes.
Close to the water tap points, there is sometimes a need to lower the hot water temperature. Our hot water mixing valves ensure the outlet water temperature is safe for consumption.
Self-limiting heating cables provide power only where needed adapting output according to the ambient temperature. It helps to reduce water waste as you can get hot water immediately providing appropriate disinfection to suppress the Legionella bacteria.

MTCV Thermal balancing valves provide a dynamic, temperature based, balancing solution for drinking water applications. Combined with the CCR2+ a smart and energy-efficient electronic control solution for monitoring and disinfecting DHW systems is established.
Domestic hot water systems with water tank are solutions suitable for centralized installations for hot water preparation, such as hospitals, hotels sports arenas, 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.
Substations are house heating systems or units in apartments that handle heat transfer from district heating pipes into your home to get hot water and heat on demand.
The self-limiting heating cables for indoors are used for maintenance of the hot water supply and other fluids that need to maintain a certain temperature. The self-limiting capability of the cable ensures that the output increases or decreases according to the surrounding temperature. It ensures hot water in all taps, providing savings compared to a circulatory hot water system.
Rotary valves are primarily designed for regulation of flow and temperature in heating systems where a certain leakage can be accepted and where a defined control characteristic is not required.
Building: Hotel/resort Application: Renovating the Domestic Hot Water (DHW) system to stabilize water temperatures Challenge: Reduce hot water wait times and improve energy efficiency Solution: Multifunctional Thermostatic Circulation Valves (MTCV) were installed on DHW branches for hydronic balancing.
The 2nd generation of AME 110NL(X) actuators for AB-QM 4.0 valves are significantly upgraded and designed to enhance the performance and efficiency of hydronic HVAC systems. These advanced actuators replace the existing AME 110NL(X) and AME 120NL models and deliver high-precision control due to the built-in digital step motor which has a 15x higher resolution as its predecessors.
AB-QM 4.0 CO6 Flexo, is a standardized prefab PICV connection set especially developed to streamline the design, installation, and servicing of hydronic HVAC systems, specifically radiant panels and chilled beams in four-pipe heating and cooling change-over systems.
For many years Danfoss has played an important role to establish safe Domestic Hot Water systems in hospitals, hotels, multi-family apartments and other buildings. Now our MTCV thermal balancing valves and new CCR2+ electronic controller for automatic disinfection have been significantly improved to your benefit.
