no hot water tanks - no illnesses (Service) domestic hot water tanks/boilers 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 water - a consumable - should not be heated up, i.e. 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.

All conveniences are included:

Advantages of continuous flow heating 4-stage domestic water cascade heater Compact domestic water heater for domestic applications Compared to the known form of domestic hot water heating in hot water tanks, 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• Only the amount of water that is actually withdrawn is heated.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.

Low energy consumption due to:

• 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.

Domestic hot water heating in large systems with special stratified storage tanks and domestic water cascade heaters (TWKK) Domestic hot water heating in domestic applications with e.g. OSKAR and compact domestic water heaters (TWK)

Clear advantages:

A special heat exchanger, supplied with energy from an OSKAR, is used to heat continuously flowing domestic water on demand, that is, only when you need it.

This heat exchanger is located externally to the tank, has a temperature control and limiter and thus a permanent preventive mechanism against calcification and scalding.
