Probably
the most preventable yet very costly failure is freezing.
This is normally accompanied by the bursting of piping and
equipment.
Most
freezing occurs because of air stratification, low flow due to
clogging, failure to remove air from a heat exchanger,
poor system design and, of course, low temperatures.
While at
first glance, it may appear that freezing is not related to
water treatment and water chemistry, this is simply not the
case.
Poor water treatment and failure to make
the necessary repairs can lead to clogging and it formation which
causes low flow.
Additionally, leaks elsewhere in the
system can cause unnecessary amounts of city water to be introduced
which enters with entrained air. Clogging can also limit the
effectiveness of automatic air injectors. The use of glycol can
provide a measure of protection which produces a larger margin for
error with respect to water management and maintenance.
