Drinking water cascade heating TWKK

Maximum performance for greater power

Drinking water heating using the flow principle is the optimal solution for properties with high demand (e.g., hospitals, hotels, sports facilities, etc.) where high drinking water hygiene standards must be ensured. Cascading achieves a high degree of control accuracy across a wide range of drinking water requirements – from the use of a single tap to peak loads. Trinkwassererwärmung

The advantages of the drinking water cascade heater at a glance:

Compact unit fully assembled and insulated for minimal losses
Heats quickly and reliably exactly as much water as needed
High power reserves of the cascade solutions, with optimum efficiency at every operating point
Extremely short response time for fresh water requests
Highly efficient circulation and disinfection station as part of the cascade
Flexible adaptation to high hot water demand through parallel connection

Better hygiene and disinfection

In large systems, technical measures to reduce Legionella growth must be observed in accordance with the Drinking Water Ordinance. According to this, systems with a drinking water volume of more than 400 l and/or a pipe volume greater than 3 l between the drinking water heating outlet and the tapping point must be heated to at least 60 °C at least once a day, evenly throughout the system. In addition, the temperature in the circulating hot water system must not be more than 5 degrees below the storage outlet temperature. The greater the volume of hot drinking water stored, the more heat energy is required for the prescribed disinfection of the system. Our fresh water technology, in combination with the appropriate control technology, performs these tasks very efficiently and reliably.
