Partial softening
The following products are currently approved by BAXI:
- Sodium ion exchanger "Fillsoft" from Reflex (www.reflex.de)
- "Heifisoft" from Judo (www.judo-online.de)
- "Heating water softening 3200“ from Syr (www.syr.de)
- "AQA therm" and "HBA 100" from BWT Wassertechnik (www.bwt.de)
It must be ensured with an automatic blending device that the min. hardness
does not go under 6°dH .
The specifications of the manufacturer must be followed.
Further products are currently undergoing testing. Please ask BAXI for more in-
formation.
Caution!
If non-approved products are used, the guarantee becomes void.
Antifreeze
Using antifreeze with BAXI gas condensing boilers with aluminium heat ex-
changers
The heat transfer medium (Lasacor
®
LS 1) offered for solar thermal systems is also
used in heating systems (e.g. holiday houses) as an antifreeze. In the mixture sup-
plied in the canisters (42 % Lasacor
®
LS 1, 58 % water) the freezing point ("crystal
formation point") is -28 °C. Due to the thermal capacity, which is lower than that
of pure water, and the higher viscosity, boiling noises may occur in some systems.
For most heating systems, frost protection down to -28 °C is not required; -15 °C is
usually sufficient. To set this operating point, the heat transfer medium should be
diluted with water in a ratio of 2:1. This mixing ratio has been test by BAXI in
relation to its practical suitability for use with gas condensing boilers.
Note
: The heat transfer medium Lasacor
®
LS 1 up to a mixing ratio of 2,5:1 is ap-
proved as an antifreeze down to -15 °C for use with BAXI gas condensing boil-
ers.
Caution! Keep the installation room free of frost.
If antifreeze is used, pipework, radiators and gas condensing boilers are protected
against frost damage. For the gas condensing boiler to be ready for operation at
any time, suitable measures must also be taken to keep the installation room free
of frost. If applicable, please also note special measures for any installed DHW
heaters.
The table shows the relevant amounts of heat transfer medium and water, that
need to be mixed together for varying volumes of water. If other frost protection
temperatures are required in exceptional cases, individual calculations can be
made.
