Baseboard Heat Noise

When my baseboard heating unit turns on, in some rooms, it sounds like someone is taking a hammer to the pipes. What is the cause and how can I fix it?


Re: Baseboard Heat Noise

I've had the same problem and here's what I've read... Good luck!

Baseboard heat noise solutions:

• Plastic gliders (not metal)
• Expansion compensators on long runs
• Outdoor-air reset control (water cycles continuously, varies boiler temp)

Banging (water boiling – check temp, should be less than 210 at all times – have read less than 220.)
• TURN BOILER TEMP DOWN! this is dangerous.

Banging (pipe expanding against too-small hole in floor or wall)
• Bleed system
• Bigger hole
• “high heat caulking compound” applied to hole
• Outdoor-air reset control mitigate but not solve

Banging (fast-closing zone valve – before circulator stops)
• Bleed system
• Check expansion tank
• fast-closing cause this: Honeywell, Erie, small White Rogers
• slow-closing solve: Taco, large White Rogers
