Why Can’t I Spot a Boiler Leak on My Own?
Boilers contain few mechanical parts and therefore have a reduced need for repairs compared to a heating system like a furnace or a heat pump. However, because boilers use hydronic power (water) to provide heat, they are susceptible to two specific problems: corrosion and leaking. The former is often the cause of the latter, although there are a number of other reasons for leaks to occur.
