How often should you have a stove swept?

2 min read

If you only light your log-burning stove now and then, one chimney sweep a year is generally sufficient. Four annual sweeps are not prescribed for this occasional use. There is an important distinction, though: having the chimney swept does not automatically include cleaning the inside of the stove. That needs its own schedule based on the appliance and how you use it.

What needs cleaning inside the stove

Ash does not stay in the firebox. It can also collect in the connecting flue pipe and the passages that carry hot gases through the stove. Deposits need removing so those passages stay clear and the stove can transfer heat properly.

Many installations require these areas to be cleaned annually. Some components, including those in pellet stoves or appliances with catalysts, need attention much more often. We’ll talk through how often your stove needs cleaning, taking into account the stove you have, the manufacturer’s guidance and how often you use it.

When to arrange the first service

Have a new stove checked by the end of its first heating season. That gives us a chance to assess deposits and check that the firing routine suits the appliance. We can then agree a sensible maintenance schedule. Do not wait for a routine visit if the draught deteriorates or other problems appear. If smoke enters the room, stop using the stove and have the cause checked.

When booking, tell us the make, model and how often you use it. If you are unsure what kind of stove you have, a photograph will help.

The chimney has its own schedule

In Germany, the Kehr- und Überprüfungsordnung generally specifies one chimney sweep a year for occasionally used log-burning stoves. More than occasional but irregular use means two. Regular use during the heating season means three, while regular use throughout the year means four. Pellet-burning appliances generally require two sweeps a year under the regulation.

The binding work and deadlines for your installation are set out in your official notice, the Feuerstättenbescheid. This tells you exactly how often your chimney needs sweeping.

Keep that notice with the stove manual so you have both available when arranging work. Only carry out everyday cleaning once the appliance is completely cold, following its instructions.
