Where chemicals are used as part of the
corrosion protection, we recommend
that the manufacturer of the chemicals
issues a certificate of suitability of the
additives with regard to the boiler mate-
rials and the materials of the other heat-
ing system components. We recom-
mend you refer questions regarding
water treatment to an appropriate spe-
cialist.
