Water treatment for condensing boilers in retrofit
Water treatment for condensing boilers in retrofit
(OP)
I'm told that the the new generation of low temperature condensing hot water boilers (aluminum or stainless steel heat exchangers) are more sensitive to water quality than traditional copper or steel boilers.
My particular interest is in retrofit situations where the existing piping is full of scale and sludge. Are there any guidelines for water chemistry that will protect the new boilers as well as the existing (old) black pipe? Are North American water treatment companies and/or contractors generally up to speed on this? Are there any high risk points? In a related topic, should I think about dielectric couplings on the pipe connections?
