Prüller LE 30 – 28 kW

Manually fueled boiler for central heating systems.The unit identified based on the original data plate has the production mark 06/1996, serial number 0851.

Key features and practical benefits

• 28 kW with split logs: output indicated on the original plate; must be sized together with the required building heat demand and hydraulics.
• 28 kW with chopped brushwood/wood and coal: the data plate also lists Buschholzhackgut and Kohle as fuels. The permitted quality and dosage must be coordinated with the exact model manual.
• Maximum 3 bar boiler pressure: one of the defining factory limits for integration into the heating network.
• Maximum 95 °C flow temperature: temperature limit specified on the original plate, constant operational setting is not recommended.
• 220 V, approximately 80 W electrical data: electrical connection according to the boiler plate; this is the data for auxiliary equipment, not the 28 kW heat output.
• Specified 1.5–6 bar for safety cooling circuit: range separately indicated on the data plate; not to be confused with the 3 bar pressure limit of the boiler body.

For proper application, the chimney, return protection, buffer tank, and safety cooling must be coordinated together with the entire heating system. It is not provided without a document certifying automatic fuel feeding, lambda control, or completed testing.

A downloadable factory operating manual for the exact LE 30 model has not been found yet. The numerical data above originate from the original data plate; documents of other Prüller or Solarfocus models are not used as the device's own manual.
