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 heated building; for wood/coal boilers also bear in mind that the boiler burns for several hours at essentially constant output on a single load - it is therefore common practice to add a buffer (accumulation) tank, which stores the surplus heat for later use instead of forcing the boiler to run inefficiently at a reduced output.
• 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 thermoregulating 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 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 firewood 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 the boiler is put into operation, and regularly during its use (typically once a year for solid fuels), a chimney inspection/cleaning by an authorised chimney sweep is legally required - 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? This typically includes regular removal of ash and cleaning of the heating surfaces/flue gas paths of soot (interval depending on intensity of use, usually a matter of weeks), plus a thorough annual inspection including seals and the chimney.
• Can I install the boiler myself? The actual placement and connection of the boiler to the heating system, chimney and safety elements should be carried out, or at least professionally checked, by a heating technician - this is an appliance with an open flame, high temperatures and pressurised parts, where a wiring/connection error can be a safety risk.
