2. Description
2.1. General description
The iDM-Hygienik 2.0 is a complete water heater with
hygienic hot water supply using a counterflow plate
heat exchanger.
The tank containing heating water is heated as re-
quired via an external heat generator (e.g. via a heat
pump, an oil or gas boiler, wood boiler,...).
The hot water is heated in a continuous process via
a large-area counterflow heat exchanger made of
stainless steel. This prevents bacterial growth. Two
hose connections and an isolating valve are provided
for easy decalcification of the plate heat exchanger.
The plate heat exchanger is supplied with heat from
the tank via a speed-controlled primary circuit pump.
The primary circuit pump is activated via a flow switch
in the cold water line.
The tank is suitable for charging with an iDM heat
pump. A screw-in electric heating immerser can also
be used to heat the tank. In addition, a solar system
can be integrated directly when equipped with a
smooth tube heat exchanger, or by installing a solar
station, which is available as an accessory.
The iDM-Hygienik 2.0 is available in two versions:
-With layer separate plate (suitable in the upper sec-
tion for hot water heating and in the lower area as a
buffer storage tank). The layer separate plate main-
tains temperature stratification, in particular when
using the Hygienik 2.0 with an iDM heat pump.
-Without layer separate plate (only for hot water
heating)
-The Hygienik 825 with stratified separation plate
is also available in a version with an integrated
smooth tube heat exchanger for solar integration.
Application range
With the Hygienik 2.0, hot water tapping quantities of
up to 70 l/min. can be achieved. Large-scale prem-
ises can be supplied by combining several tanks.
Scope of delivery
The Hygienik 2.0 comprises a storage tank with all
necessary connections and two sensor rails for
precise positioning of the required sensors. The tank
body is equipped with fleece/Neopor® insulation and
enclosed in a plastic outer shell with a gray cover.
2.2. Hot water station
The hot water station can either be mounted directly
on the Hygienik 2.0 or on a wall. This means it is also
possible to operate the hot water station with a tank
made by another manufacturer.
Scope of delivery:
- Hot water stations 25 l or 35 l with or without
mixing valve
- Hot water stations 50 l or 70 l
- Bracket for installation of the hot water station on
a wall
- Screws for mounting the hot water station on the
Hygienik
- iDM cover hood for the hot water station, made
from EPP rigid foam
- Installation instruction

Description
2.3. Notes on dimensioning
The Hygienik 2.0 is available in various combinations
for different tank and heat exchanger sizes. The fol-
lowing criteria must be considered in order to select
the appropriate type.
“Single tapping volume”
This is the total quantity of hot water at 45 °C that
can be tapped from a Hygienik 2.0 when the tank is
heated to 60°C right to the bottom and is not reheated
by the heat generator.
“Hot water requirement”
The hot water requirement for a building must be
defined in accordance with DIN 4708, Part 2 or using
the “Sander method.” A suitable Hygienik 2.0 type is
then selected from the table below.
The exact design of the Hygienik storage tank
and hot water station is carried out according to
the specifications in the heat pump manual.

“Tapping output” of the plate heat exchanger
The tapping output is the current maximum hot water
tapping quantity that can be heated by the plate heat
exchanger from a cold water temperature of 10°C to
50°C at a tank temperature of 55°C.
The selection of the appropriate plate heat exchanger
type will depend on the number of residential units
and the equipment on the drinking water side. Refer
to DIN 4708, Part 2, for information on dimensioning.
Hot water stations are available with the following
tapping outputs:
-25 l / min.

Installation
4. Installation
The iDM Hygienik 2.0 should be installed as close as
possible to the drinking water tapping points to keep
water lines as short as possible and avoid the need
for a circulation line.
During storage, transport and installation of the
equipment, it must be ensured that it is not subjected
to mechanical forces such as warping, scratches and
tension.
4.2. Installation location of the Hygienik
2.0
The iDM Hygienik 2.0 must be installed in a frost-
proof room by a licensed specialist firm. The pertinent
laws, regulations and standards both for boiler house
pipework and drinking water installations must be
observed.
Minimum distances required for installation and ser-
vicing work must be observed based on the specific
installation situation, the routing of pipework and the
size of the installation room.
4.3. Connecting sockets of the Hygienik
2.0
In order to avoid heat losses, openings are not pro-
vided for all sockets in the insulation jacket. Additional
connections can be used by breaking open the rel-
evant perforations.
The insulation jacket and the hood must
not be exposed to intense sunlight or other
heat sources. There is a risk of damage to
the insulation and the surface.
To prevent corrosion inside the tank, follow
the instructions with regard to the heating
water!
By selecting a decentralized position for
the hot water stations near the tapping
points (e.g. inside the residential units),
the content of the hot water pipes can be
reduced to under 3 l.
Do not use abrasive or cleaning solutions
containing solvents to clean the high-gloss
front of the insulation. Thereby, the surface
can become brittle and it comes to crack-
ing. Such damages are excluded from the
warranty.
4.1. Installation conditions for the Hygienik 2.0
pic.: Cracks in the hig-gloss front of the insulation
caused by solvent-based cleaners.
pic.: Damaged insulation caused by improper stor-
age.
