Boiler Making loud noises
- Check for rumbling or grinding noises that may indicate a problem with the burner motor or fuel pump. Replace defective parts.
- Listen for hissing, whistling, or roaring sounds that could mean combustion air or flue gas flow issues. Inspect venting.
- Bangs or pops may signal delayed ignition caused by faulty electrodes or improper fuel atomization. Check electrodes and nozzle.
- Knocking or hammering noises likely indicate heat exchanger or furnace issues.
- Inspect boiler base and mountings for looseness. Tighten fasteners if boiler is rattling against floor or walls.
- Check for vibrating pipes that may need support braces or pipe clamps to reduce rattles from water circulation.
- Make sure fuel tank is not empty causing sputtering from lack of steady oil supply while burner runs. Refill tank.
- Listen and isolate source of hissing or squealing indications potential steam or water leaks. Repair any found leaks.
