I've lived in my home for going on 17 years. Just recently my heating system started making a fairly loud humming noise. It sounds like it's comming from my boilermate hot water heater. I installed a spirovent air eliminator that didn't help and I've replaced the circulating pump. What is the problem? Perplexed to say the least. Thanks Scott.
