Compact Pellet Tank AZPU

Product detailed description

- with a volume of 240 L and 400 L, together with the DRA 25 conveyor, designed for confined spaces in small boiler rooms.
It allows the pellet tank to be placed in close proximity to the boiler so that the whole assembly takes up as little space as possible.

The AZPU set is designed for gasification boilers adapted for a pellet burner (DRA 25 conveyor - 1.7 m, 25 W gearmotor).

FAQ

• 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. With wood/coal boilers, however, also bear in mind that the boiler burns for several hours at essentially constant output during a single fill - which is why it is common practice to add a buffer (accumulation) tank to the boiler, which stores surplus heat for later use instead of forcing the boiler to run inefficiently damped down.
• What else do I need to install this boiler? Besides the boiler itself, the system usually requires: a buffer (accumulation) tank of appropriate volume, a circulation pump (often already with a built-in Laddomat or thermoregulatory valve protecting the boiler against low-temperature corrosion), a safety valve, an expansion vessel, and a flue/chimney with sufficient draught corresponding to the boiler's output - you will find the exact draught values in the technical parameters above.
• What fuel is suitable, and what isn't? Use only the fuel recommended by the manufacturer for the given model (typically split logs of a defined length and moisture content, or possibly lignite briquettes or coal, depending on the boiler type) - unsuitable or overly wet 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 (usually 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 could also be disputed.
• How much maintenance does the boiler require? This typically includes regularly removing ash and cleaning the heat exchange surfaces/flue gas passages of soot (the interval depends on intensity of use, usually on the order 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 checked, by a heating technician - this is an appliance with an open flame, high temperatures, and pressurised components, where a connection error can be a safety risk.
