substances so that the device warranty does not lose its validity
otherwise it will have a negative effect on the operation of the boiler.
We comply with the standards laid down in the standards for domestic
water and heating installations in order to prevent the accumulation of
lime in the heating installation and therefore the erroneous operation
of the installation.
Preventive water treatment procedure for cast aluminium
heat exchange
The following descriptions describe the quality of water required
for aluminium heat exchangers. In order to obtain the required heat
transfer, the installation water must be of good quality. Parameters such
as PH, hardness, conductivity, oxygen, flux residues, oil residues and
corrosion products due to installation can have negative effects on the
heat exchanger.
Before filling (old and new) the installation, it should be thoroughly
rinsed in accordance with EN 14336 with clean running water from the
faucet.
For water treatment Warmhaus only permits the products listed below.
For the protection and long-term use of the heat exchanger,
Warmhaus always specifies the following criteria for the quality of
the installation water and the filling water:
• PH should be kept between 6.5 and 8.5.
• The maximum permissible chlorine content for the aluminium heat
exchanger is 250 mg/litre.

Caution:
Before making the connection to the boiler, make
sure that any residues in the main heat exchanger (pipes,
heating appliances, etc.) are removed using solvents or similar

The room thermostat should be installed at
a distance of 1.25 to 1.5 m from the floor.
It should be at least 30 cm away from the open
