Atmos A25 Burner Combustion Chamber

Product detailed description

Combustion chamber H0228 for Atmos A25 pellet burner

Code H0228 designates a replacement combustion chamber, in practice the cup or bowl of a pellet burner. The part belongs to the group of spare parts for pellet burners and augers. It is intended for Atmos A25 burners with serial number 160 and higher.

Note the version with pneumatic cleaning

This chamber does not fit a burner that is cleaned by a compressor. If you have an Atmos A 25 pellet burner with pneumatic cleaning, order the chamber for the Atmos A 25 burner with pneumatic cleaning instead.

Before ordering, therefore, check which version of the burner you have and what its serial number is.

Frequently asked questions

• How do I choose the right output for a solid fuel boiler? Base it on the calculated heat loss of the heated building. With wood/coal boilers, however, also consider that the boiler burns for several hours per load at essentially constant output - which is why it is common practice to add an accumulation tank to the boiler, which stores the excess heat for later use instead of the boiler having to be throttled down inefficiently.
• What else do I need to install this boiler? Besides the boiler itself, the system usually requires: an accumulation (buffer) tank of suitable volume, a circulation pump (often already with a built-in Laddomat or a thermostatic valve protecting the boiler against low-temperature corrosion), a safety valve, an expansion vessel and a flue/chimney with sufficient draught matching the boiler output - you will find the exact chimney draught values in the technical parameters above.
• Which fuel is suitable and which is not? Use only the fuel recommended by the manufacturer for the given model (usually logs of defined length and moisture content, or brown coal briquettes or coal, depending on the boiler type) - unsuitable or overly moist fuel reduces efficiency, increases the formation of tar and deposits, and may damage the boiler.
• What about the chimney inspection and legislation? Before the boiler is put into operation, and also regularly during its use (usually once a year for solid fuels), an inspection/cleaning of the chimney by an authorized chimney sweep is required by law - without the relevant inspection certificate, an insurance claim in the event of a fire may also be disputed.
• How much maintenance does the boiler require? It usually includes regular ash removal and cleaning of the heat exchange surfaces/flue gas passages of soot (the interval depends on the intensity of use, usually in the order of weeks), and a thorough inspection once a year, including the seals and the chimney.
• Can I install the boiler myself? The positioning and connection of the boiler to the heating system, the chimney and the safety components should be carried out, or at least professionally checked, by a heating technician - this is an appliance with an open fire, high temperatures and pressure components, where a mistake in the connection can pose a safety risk.
