Product information

Description

The Heiztechnik ONE PLUS BASIC 11 kW is a solid-fuel boiler engineered for central heating in residential properties. It delivers a nominal heat output of 11 kW and integrates automatic cleaning and combustion optimization features to maintain efficient operation. The boiler includes a WRZ-type fuel hopper for reliable fuel feeding, an STD control interface for system management and a Lambda sensor to monitor and adjust the air/fuel ratio for cleaner combustion and stable heat delivery.

Advantages

The automatic cleaning system reduces manual maintenance by periodically removing ash and soot from the combustion chamber, helping to maintain thermal efficiency over time. The Lambda sensor provides real-time feedback on combustion quality, enabling the control system to optimize air supply and fuel burn for improved fuel efficiency and reduced emissions. The WRZ fuel hopper design ensures steady fuel feed and compatibility with a variety of solid fuels commonly used in domestic heating. The STD control interface offers accessible operation and basic automation for temperature regulation and system scheduling.

Suitable for

  • Heating single-family homes and small residential buildings with a central heating system
  • Systems where automatic ash and soot management reduces manual maintenance needs
  • Installations requiring regulated heat output and combustion control for improved fuel economy
  • Retrofit or new installations using wood, briquettes, or other approved solid fuels compatible with WRZ-type hoppers

Key specifications

  • Nominal heat output: 11 kW
  • Fuel type: solid fuels suitable for WRZ hopper (e.g., wood, briquettes)
  • Automatic cleaning system for combustion chamber ash and soot removal
  • WRZ-type fuel hopper for continuous fuel feeding
  • Control interface: STD control for temperature regulation and basic automation
  • Lambda air/fuel sensor for combustion optimization

How to use

Install the boiler according to local regulations and manufacturer installation guidelines, ensuring correct flue connection and safe clearances. Fill the WRZ fuel hopper with the recommended solid fuel and set the desired room or system temperature on the STD control interface. During operation the Lambda sensor and control system will monitor combustion and adjust air supply to maintain efficient burning. Periodically inspect ash collection points and fuel feed components; the automatic cleaning system will reduce the frequency of manual cleaning but routine checks are still necessary to ensure safe operation.

Usage recommendations

Use dry, properly sized fuel recommended for WRZ hoppers to ensure consistent feeding and efficient combustion. Schedule regular professional maintenance and chimney inspections, and follow local safety and installation codes. When replacing components or performing adjustments, consult official Heiztechnik documentation or an authorized technician to preserve combustion control accuracy and safe operation.
