My HB Smith boiler (Mod. #G-100W.5/Ser. # 1393-2115) makes a boiling water sound that resonates throughout the house upon heat generation. The system is gas generated forced hot water to baseboard and radiant floor heating.
The boiling water sound is restricted to the boiler and echos along the walls. There is no sound of banging in the pipes.
