Do pellet boilers make a noise?
You do get a noise from the auger that feeds the combustion chamber with pellets from the hopper. This sounds like a quiet mechanical whirr about every thirty seconds that lasts for about half a second. The noise of combustion is a low hum very similar to an oil fired boiler. As most biomass boilers are designed to be situated away from a living space this is not usually a problem. If the appliance is fitted into a living space the noise from the stove will soon become unnoticable.
