homeowners question

david_22

I just had a viessman boiler with a riello burner installed in my home. I was surprised once the job was finished that the sounds of the burner (or boiler?) were louder then the old unit I had ripped out. Heck I can even hear it standing out in my driveway. I was wondering if this is to be expected or if not is there a simple remedy?

thanks

riello's make noise in the chimney . If you had an old low pressure burner , the new ones will always make more noise . Sometimes you can make changes to the flue as it enters the chimney to help .

noisey Riello in a Viessman

exhaust "mufflers" are available to help attenuate some of the burner noise as a lot of the objectionable sound is emitted by the vent. As you installer to ask his distributor.

Did you tell is which Viessmann boiler you chose?

noisy boiler

Is the first piece of breeching out of the boiler very short, or does it make a 90* trun immediately? This will add to the noise and Viessmann says a 24" straight run oot of the boiler will minimize "chimney howl"

The funny thing is...

... I don't hear the boiler firing, but I do hear the circulators doing their work if it's quiet and I'm in a room with a wall in which the supply pipes are running. That's despite the near immeadiate 90° elbow in the flue at the back of Ms. Vitola. There is maybe 8" there, no more.

Perhaps some of these chimney howls are resonance issues?
