HWBB moan and groan

Move. :)

Clearly you know the cause (bang-bang control with a single high temperature). Short of installing plastic slide cradles and insert sleeves along every ever-loving inch of the system, the use of outdoor reset and constant circulation can and will work wonders.

Absent that, Atlas Van Lines is running a special this week.

    I realize and expect noises from the copper-fin HWBB that is in my house. It makes sense to me that I have to live with expansion and contraction of the pipes/fins and the moans and ticks that come with it.

    What I am trying to eliminate is the louder "pinging" noises which sound almost like someone ringing a bell once. "PING", and "TING". Well, looks stupid written down but hopefully you get the idea.

    These noises only occur on startup of a heating cycle, obviously during expansion of pipes etc. I thought maybe it had to do with the cover of the fins rubbing against them but unlatching the cover didn't help. These are loud enough to wake me up, but thankfully my 2 year old seems to sleep through them.

    I don't have a modulating boiler - it is a W-M cast iron "bang-bang" boiler. All-or-nothing.

    Any ideas on how to combat these loud (ring-like) noises without making system changes?

    I have had some success

    with placing the circulator on constant circulation. Is the noise is generally at the begining of the cycle? like when the first slug of real hot water rushes through the system? if so, try constant circ, allows a more gradual ramp up of temperature in the HWBB minimizing sudden expansion noises.

    Pinging Baseboard

    You didn't mention what type of Baseboard you have. Regardless, give me a call at 516-484-2600. I will see what I can do with regard to some suggestions. There always seems to be a pretty simple solution to these problems.
