Does a radiant heat system produce a hum or vibrating noise?

Deb_4 Member Posts: 5
We are building a new house and have a radiant heat system. There is a loud hum or vibrating noise that comes from the boiler room in the basement which can be clearly heard on the first floor. Is this typical of this type of system? Thanks in advance for any info you can provide.

    Deb could you post a few pics of the system? it may help us diagnose your problem. you may have piping that is secured too tightly to the wood causing noise, an over sized circulator pump a noisy draft inducer/intake fan (if applicable)

    Thanks for your responses, Gentlemen. I am unable to post pics right now due to the fact that my husband took our lead carpenter on a fishing trip this weekend and took the camera with him.

    I do believe you both might be correct that it is the piping bolted to the floor because I cannot pinpoint the origination of the noise - it is kind of a "general" noise, so the piping vibrating on the wood makes sense.

    Unfortunately, the heating system has been the "thorn" in our building project. Though we hired a professional in our area who has been in the HVAC business for 20+ plus years and whom my husband knows personally, we found out too late that he is not an expert at radiant heat. At one point, he and his crew had the water coming into the boiler the wrong way (our electrican diagnosed this problem) and they had to replace the boiler. I could go on and on about this experience, but I don't want to bore you. Anyway, do you you think we should hire someone to look at the system to determine where this noise is coming from and to make sure the system is, in general, properly installed? How would I find someone, who we would know for sure, is an expert at radiant, since we failed so miserably at doing so?

    Hey Deb

    Check out the find a Contractor part of this web site. My guess from this side of the internet would be an oversized circulator. If someone is'nt sure about sizing something they always seem to go larger. This is not always a good thing. (for example, the double quarter pounder). Let us know how it goes. WW

    It could be...

    it's humming because no one ever taught it the words, and its vibrating because of too much coffee:-)

    It could also be a solder ball caught in the impeller of the pump.

    Where abouts in this fine country of ours are you located?

    Too far for me...

    I'm in Denver. Not knowing the lay of the land, I can only suggest some people I know that do know what they're doing. Maybe, if they're not close enough, they know someone that is.

    They're both good guys.

    Good Luck in your adventure. Sorry it didn't turn out for the best, but once straightened out you WILL have the most comfortable system there is.
