Terming Kula OZON 25 - Pellet Boiler (25 kW)

Multi-fuel pellet boiler for maximum fuel flexibility

The Terming Kula OZON 25 pellet boiler (25 kW) is designed for users who want maximum freedom in fuel selection. While conventional pellet boilers are often limited to premium wood pellets, the OZON series is built as a true multi-fuel pellet boiler. In addition to wood pellets, it can burn agro pellets, grain pellets, soy pellets, corn kernels and other granular biomass fuels.

Designed for alternative biomass fuels

The Terming Kula OZON 25 clearly stands apart from standard pellet boilers due to its multi-fuel capability. This makes the boiler especially interesting for users who have access to alternative fuels or want to be less dependent on standard wood pellets. The broad fuel compatibility offers more flexibility and can help manage heating costs more effectively.

Patented burner with moving grate

The heart of the boiler is the patented TERMING burner with a moving grate. This technology enables safe and efficient combustion of various biomass fuels. The burner is designed to handle different ash contents and fuel characteristics reliably, without negatively affecting the operating reliability of the installation.

Automatic ash removal for agro pellets and biomass

Burning agro pellets and other alternative biomass fuels generally produces more ash than standard wood pellets. That is why the OZON series is equipped as standard with an automatic screw-driven ash removal system. Excess ash is discharged automatically, helping the burner continue to operate reliably even with fuels that have a higher ash content.

Modern control system with integrated WiFi

The latest generation electronics provide reliable control of the complete combustion process. The boiler is also equipped with WiFi connectivity as standard. Via smartphone, tablet or computer, users can check the system status, adjust settings and change operating modes with ease.

High efficiency and maintenance-friendly design

The OZON boiler construction is based on a proven design focused on high efficiency, easy maintenance and long service life. The heat exchanger can be cleaned using the integrated turbulators. With a single movement, deposits can be removed, helping maintain heat transfer and simplifying routine maintenance.

Suitable for homes and larger heating systems

With an output of 25 kW, the Terming Kula OZON 25 is suitable for larger homes, commercial spaces, workshops and other heating systems with higher heat demand. Combined with a correctly sized buffer tank, it creates an efficient biomass heating system with stable heat output and optimal use of available fuels.

CE-certified according to modern environmental requirements

The latest CE certification confirms the OZON series’ performance in terms of emissions, safety and efficiency. This means the boiler meets modern European requirements for biomass boilers and provides a reliable foundation for sustainable heating systems.
