Near boiler piping of Condensing Boilers
Do Condensing boilers pump away or into the boiler?
Does it depend on the manufacturer? I'm guessing the lower temps leaving the boiler do not cause the same issues relating to Henry's Law that non-condensing boilers have. However, why would they be piped with the circulator on the return?
Just trying to understand the theory because someone told me that Lochinvar condensing boilers suggest that.
