Gas boiler cleaning

Signs cleaning may be needed

• the boiler is noisier or heats water more slowly
• the flame is uneven or goes out
• radiators are not heating as before
• dust, soot or deposits are visible inside

What we inspect

• the combustion chamber, burner and heat exchanger
• fan, flue and condensate drain
• system pressure and temperature
• controls after cleaning

How cleaning is done

• switch off the equipment and assess its condition
• remove accessible contamination with a suitable method
• check connections and refit protective panels
• start the boiler and monitor operating values

When to call

The interval depends on the model and operating conditions. If noise, heating or the flame has changed, arrange an inspection before the cold season.
