Every Bock indirect water heater we install is sized to your household and piped as a dedicated boiler zone with the right priority controls, so your boiler makes domestic hot water efficiently. We set the aquastat, circulator, T&P relief valve, and expansion tank, pull permits, and remove the old unit.
An indirect only performs when it is matched to your boiler and piped correctly. See our boiler brands or browse all indirect water heater brands.
