Boiler tube brush size is matched to the tube's outer diameter, so measuring the tube first (commonly 1-1/4" up to 4" OD) helps ensure the correct brush head fits.
What is the difference between wire and fiber brush heads?
Wire brush heads are more aggressive and suited to heavier soot or scale buildup, while fiber brush heads are gentler and often used for routine cleaning.
How often should boiler tubes be brushed?
Most manufacturers recommend cleaning boiler tubes annually, typically before the start of heating season, to maintain efficiency and prevent soot buildup.
Do brush rods come in different lengths?
Yes. Brush rods are available in lengths such as 3, 4, and 6 feet, in fiberglass or steel, depending on the boiler size and access needed.
