Quick Answer
Masonry heaters produce significantly less noise than wood stoves, typically ranging from 5-20 decibels compared to the 70-85 decibels produced by wood stoves.
Noise Level Comparison
Masonry heaters are designed to operate at low temperatures and produce a gentle, soothing warmth. This is due in part to the materials used and the way the heat is distributed within the unit. In contrast, wood stoves burn wood at higher temperatures, which can produce a more intense noise.
Factors Contributing to Noise Levels
Several factors can contribute to the noise levels produced by masonry heaters, including the type of fuel used, the size and design of the unit, and the draft created by the chimney. A well-designed masonry heater with a properly functioning chimney can operate at a whisper-quiet level. For example, a 40-kilowatt masonry heater can operate at 10 decibels when burning dry wood and 15 decibels when burning damp wood.
Measuring Noise Levels
To put these noise levels into perspective, 10 decibels is roughly equivalent to the sound of a quiet library, while 20 decibels is equivalent to the sound of a gentle breeze. This is a stark contrast to the 70-85 decibels produced by a wood stove, which is equivalent to the sound of a vacuum cleaner or a lawnmower. When choosing between a masonry heater and a wood stove, noise level can be a significant consideration for homeowners who value a peaceful living environment.
