Antifreeze agent
Note
The use of antifreeze agents with Potterton gas condensing boil
ers with aluminium heat exchangers.
The heat transfer medium (Lasacor® LS 1) offered for solar thermal sys
tems is also used in heating systems (e.g. holiday houses) as an anti
freeze agent, In the mixture supplied in the canisters (42 % Lasacor® LS
1, 58 % water), the freezing point ("crystal formation point" ) is -28°C. Due
to the lower thermal capacity and higher viscosity compared with water,
boiling noises can occur under unfavourable conditions.
For most heating systems, frost protection down to -28 °C is not required;
-15 °C is usually sufficient. The heat transfer medium must be diluted 2:1
with water to set this operating point. This mixing ratio has been tested by
Potterton in relation to its practical suitability for use with gas condensing
boilers.
Note
Up to a mixing ratio of 2.5:1 the heat transfer medium Lasacor®
LS 1 is approved as an antifreeze agent down to -15 °C for use
with Potterton gas condensing boilers.
