about domestic hot water
Why not store heat in domestic hot water?

Clean solution: no domestic hot water tanks - no diseases
Domestic potable hot water - is better not be heated up and stored, as in the case of conventional domestic hot water cylinders. The outcome is frequent calcification, ongoing idle heat losses combined with the associated high energy requirements, as well as the fostering of legionella and other bacteria.
Continuous flow domestic hot water heating using ratiotherm technology prevents these system-related drawbacks and ensures hygienic, energy- efficient heating of the hot water with protection against calcification and scalding.
What are the advantages of continuous flow heating?

- High flow rates.
- Infinitely variable change in the on-demand hot water volume.
- Only the amount of water that is actually withdrawn is heated. This prevents the development of legionella.
- Lower energy consumption as a result of minimal idle heat losses and low charging temperatures.
- No additional energy needed to neutralise legionella.
- No germs due to stagnant or slightly heated water.
- Temperature limitation to below 60° C: minimises calcification and prevents scalding.
