How do I get rid of the banging noise from my cast iron baseboard heaters?
My home was built in 1967 I don't know if the heating system is original. Its baseboard cast-iron in the winter, when it very cold and we raise the temperature, throughout the night, it makes him loud banging noise. The plumber said there is no air in the system & the boiler is not overheating, nothing can be done. I'm hoping someone can help me, because we would like to sleep better at night.
Thank you Rudy
