NOTES ON STRATIFIED STORAGE TECHNOLOGY
GENERAL PRINCIPLES OF DESIGN
• Stratified storage technology thrives on temperature differences, i.e. the heat generators and heat consumers
should be designed with a high temperature spread.
• In general, a „pre-sorting“ of the different temperature levels is necessary by means of the corresponding
height positioning of the supply and return connections in the stratified tank‘s stratified insert is necessary.
• The stratified storage tank will always contain the temperatures that are supplied by the heat generators and heat
consumers.
This means that at the lowest point of the storage tank, the temperature of the coolest return flow of a heat con-
sumer will be found and at the highest point, the temperature of the warmest flow of a heat generator.
• The maximum design volume flows per connection of the respective stratified storage tank or stratified insert
must be observed.
This value is also a parameter/type when selecting the storage tank and stratification insert size.
• Constantly running circulation pumps at low temperature differences should be avoided, as they destroy the strati-
fication of the storage water.
the stratification of the storage water. When selecting condensing boilers, particular attention must be paid to this.
pay particular attention to this.
• When using controlled heating circuits, 3-way mixing valves must always be provided (no 4-way mixing valves, no
injection circuit).
• The design of the storage volume and stratification when using solar energy is primarily based on the collector
area or collector output.
Example:
Oskar°-750 Litres 8 bis 12 m²
Oskar°-1.000 Litres 10 bis 14 m² Oskar°-1.000 Litres 12 bis 14m²
Oskar°-1.300 Litres 14 bis 18m² Oskar°-2.000 Litres 18 bis 26m²
Oskar°-3.000 Litres 24 bis 32m² Oskar°-4.000 Litres 30 bis 40m²
• Since stratified storage technology is intended to make efficient use of the solar system for central heating back-
up and domestic hot water preparation, a south-facing collector system with an angle of inclination of 45° to 60°
should be installed.
• In the case of lump wood firing, the storage tank and stratification insert are usually dimensioned according to
the boiler output or the „combustion chamber volume“ (combustion output, i.e. heat quantity in kWh) as well as
according to the statutory provisions and recognised rules of technology.
• The effectiveness of heat generators and storage systems as well as the solar coverage rates increase with
minimisation of the maximum flow temperatures for heat consumers.

NOTES ON STRATIFIED STORAGE TECHNOLOGY
ADVANTAGES AND BENEFITS
• The patented, thermo-hydraulic layer system is based exclusively on physical principles/natural laws and
does not require any control technology, neither electrical nor electronic nor mechanical, to function.
• The operation of the shift system takes place without any (external) energy demand, only due to the
natural law of gravity (hot water is lighter than cold water).
• OSKAR has no wearing parts and is therefore fail-safe, maintenance-free and durable.
• OSKAR stores heat (thermal energy) in the form of neutral, unproblematic heating water, which means
that there is no risk of corrosion, calcification and germs, i.e. OSKAR has a practically unlimited service
life.
• Via the stratification system, not only heat flows from the most diverse heat generators are supplied in
layers to the storage volume, but also all return flows from the heating circuits/heat consumers, which
usually have very different temperatures.
• The patented, thermohydraulic stratification and connection system ensures stable and fast-acting
stratification of storage water of different temperatures.
• Universal use, as it is not bound to any system and is basically compatible with all heat generators, heat
consumption systems and associated control systems. Ideal combination of different heat generators,
e.g. oil/gas boiler + solid fuel boiler/tiled stove + solar. When using OSKAR, complicated hydraulic
and electrical/electronic circuits, pipe systems, as well as switching valves or other actuators/control
valves are no longer necessary. The system design is simple, the control technology is minimised and
operation is safer and more efficient.
• Best possible utilisation of solar energy, e.g. almost 40 % total energy saving when using solar energy
for heating and domestic hot water with only 10 m² collector area (result of a diploma thesis of the
Munich University of Applied Sciences, Department of Supply Engineering, based on a single-family
house in the Bavarian foothills of the Alps).
• Maximum utilisation of condensation heat with condensing technology through a return temperature
that is always cool; i.e. always the highest efficiency of the condensing heat generator.
• Optimisation of burner running times and thus reduction of burner starts up to 70 % and pollutant
emissions up to 50 %.
• Lowest heat losses, even when connected, as all connections are located at the bottom, in the coolest
storage tank area.
• Hygienic drinking water heating (domestic hot water preparation) according to the continuous flow
principle.

INTENDED USE
The ratiotherm Oskar-10 is built according to the state of the art
and the recognised technical safety regulations.
In the event of improper use or use for other than the intended purpose, hazards to life and limb of the
user or third parties may arise.
Oskar-10 is not intended to be used by persons (including children) with reduced physical,
sensory or mental capabilities.
It is also not to be operated by persons with a lack of experience and/or knowledge.
• unless they are supervised by a person responsible for their safety or have received
instructions from that person on how to use the product.
The storage tank is intended exclusively for domestic and / or commercial use
for the preparation of hot water (domestic hot water) and for heat collection and distribu-
tion.
Any other use or use that goes beyond this is considered improper use. The manufacturer/
supplier is not liable for any damage resulting from this.
The risk is borne solely by the user (operator).

ASSEMBLY
The insulation should be left in a warmer room for a longer period
of time before it is in a warmer room for a longer period of time
before installation to make it easier to fit.
Unpack the insulation and check for damage and completeness as
per the according to the enclosed parts list.
Align the storage tank with a spirit level.
The following insulation steps can also be carried out after installa-
tion.
However, it may be somewhat more difficult due to the pipework
and possibly narrow space conditions in the boiler room.
Insert the floor segments at the bottom.
Remove the foot rim panels from the insulation segment.
(Velcro fastener).
Set up the front and rear insulation segments.
Carefully guide the storage tank connections at the bottom
through the through the fleece openings.
At least 2 people are needed for this.

According to DIN 1988 and EnEV § 10, ball valves must be maintained and inspected at regular intervals.
In case of extreme stress, the inspection must be carried out at shorter intervals.
Ball valves should be operated regularly at 3-monthly intervals to ensure smooth operation and to avoid any
operation and to avoid possible deposits on the ball and thus to ensure a permanently safe
secure function in the long term!

PLATE HEAT EXCHANGER
Plate heat exchanger - Cleaning - Water values
Due to the strong turbulence in the brazed plate heat exchanger, there is a high self-cleaning effect in the channels.
Nevertheless, in some applications the formation of deposits can be very high; this is the case, for example, with extremely
hard water and high temperatures.
We recommend installing a suitable softening system and checking the condition of the heat exchanger max. 1 year
after commissioning and setting a cleaning/maintenance cycle - earlier in the case of very high water hardness. Then it is
possible to clean the heat exchanger by circulating a cleaning liquid (CIP - Cleaning In Place). Carry out cleaning at regular
intervals.
Use a container with a weak acid, either 5% phosphoric acid or, if the heat
exchanger is cleaned more frequently, 5% oxalic acid. Pump the cleaning liquid
alternately through the heat exchanger.
For high-maintenance applications, we recommend on-site installed CIP
connections/valves to simplify maintenance. For best cleaning results, the
flow rate of the cleaning solution should be 1.5 times that in operation and
All acids and bases are dangerous preferably in backwash mode.
substances and should be used with After cleaning, do not forget to rinse the heat exchanger thoroughly with clear
great care! water. A solution of 1-2% sodium hydroxide (NaOH) or sodium bicarbonate
(NaHCO ) before the final rinse ensures that all 3 acids are neutralised.
