Frequently Asked Questions

• How do I choose the right output for a solid fuel boiler? Base your choice on the calculated heat loss of the building being heated. For wood/coal boilers, also keep in mind that the boiler burns for several hours at essentially constant output on a single fill - which is why it's common practice to add a buffer (accumulation) tank to the boiler, storing surplus heat for later use instead of forcing the boiler to run inefficiently throttled down.
• What else do I need to install this boiler? Besides the boiler itself, the system usually requires: a suitably sized buffer (accumulation) tank, a circulation pump (often already fitted with a Laddomat or a thermoregulatory valve to protect the boiler against low-temperature corrosion), a safety valve, an expansion vessel, and a flue/chimney with sufficient draught matching the boiler's output - exact chimney draught values can be found in the technical parameters above.
• What fuel is suitable, and what isn't? Use only fuel recommended by the manufacturer for the given model (typically split logs of a defined length and moisture content, or lignite briquettes or coal depending on the boiler type) - unsuitable or overly damp fuel reduces efficiency, increases tar and deposit build-up, and can damage the boiler.
• What about chimney inspection and legislation? Before putting the boiler into operation, and regularly during its use (usually once a year for solid fuels), the chimney must by law be inspected/cleaned by an authorized chimney sweep - without the relevant inspection certificate, an insurance claim in the event of a fire could also be disputed.
• How much maintenance does the boiler need? This typically includes regularly removing ash and cleaning the heat exchange surfaces/flue gas passages of soot (interval depending on usage intensity, usually a matter of weeks), plus a thorough annual inspection including seals and the chimney.
• Can I install the boiler myself? The positioning and connection of the boiler to the heating system, chimney, and safety components should be carried out, or at least professionally inspected, by a heating technician - this is equipment involving open flame, high temperatures, and pressurized components, where an installation error can pose a safety risk.
