Initial fill water may contain enough minerals to produce damaging deposits. Additional untreated makeup water will increase scale buildup.
Contamination may also come from scale and rust buildup inside the piping and heat distribution units of an older boiler system replaced with small multiple boiler units. The result can lead to loss of efficiency and component failure.
1.Follow proper
2.Hot water systems should not require makeup water after initial fill. Use manual feed water systems or install a water meter to detect leaks.
