PLEASE Help! We bought a house last year with this Gas Hot water boiler and don’t know if we need service or what – when it “clicks” on it’s more than a click – it’s quite loud and enough to nearly wake a light sleeper when it clicks on at night. When it runs it’s just hums a little, but when it comes on (and off) it doen’st seem like it should be that loud. Any other advice or direction anyone could share would help..I treid to find the company that made ours to get a booklet or something and they seem to have gone out of buisness. We don’t know anything about these type of heaters and would like to educate ourselves. Thanks a million!
