Heating circuit water quality
The composition and quality of the
system water have a direct influence on
the performance of the whole system
and the life of the boiler. On first filling,
and any subsequent refilling, a pH
balance of 7-8 should be maintained.
Please see the table below
The system must be flushed, cleansed
and treated with a good quality
corrosion inhibitor suitable for all the
materials in the system before the
boiler is put into use
.
Failure to do this may affect the
boilers warranty.
No Chemical anti-corrosion medium
should be introduced to the system
