Domestic hot water heating
Why not store heat in domestic hot water?
Theoretical principles: What do good stratified storage tanks look like?
Clean solution: no hot water tanks - no illnesses
Potable water tanks used to be common and, unfortunately, are still widely used these days as the standard solution for domestic hot water heating - with all of its known drawbacks and problems:
Domestic potable hot water - a consumable - should not be heated up and stored. The outcome is frequent calcification, ongoing idle heat losses with associated high energy requirements, as well as the fostering of legionella and other germs.
What does the solution look like?
An end to all of this: Simply replace your (service) domestic hot water tank with a ratiotherm stratified storage tank with adapted instant water heater to heat domestic water using the hygienic continuous flow principle.
Compared to the known form of domestic hot water heating in domestic hot water cylinders, continuous flow heating with ratiotherm technology delivers nothing but benefits:
- 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- Only the amount of water that is actually withdrawn is heated.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 - low charging temperatures - no additional energy needed to neutralise legionella
- no germs due to stagnant or slightly heated water such as at the bottom of a hot water tank
- Temperature limitation during charging of the heat exchanger to below 60 °C: reduces calcification to a minimum and safeguards against excessive discharge temperatures.
