Defro Epsilon F 15 kW pellet boiler with autom. WT cleaning and ash output

EPSILON F – compact pellet boiler with central pellet burner

Product overview

The EPSILON F is a modern pellet boiler designed for compact construction and maximum ease of use. It combines the latest technology and sophisticated design to provide you with a reliable and cost-effective heating experience.

With innovative features and first-class equipment, this pellet boiler offers the ideal solution for anyone looking for an environmentally friendly alternative to fossil fuels.

Design and structure

The sophisticated design of the EPSILON F features a compact boiler structure that can be ideally integrated into a wide variety of room concepts. If necessary, the pellet hopper capacity can be optionally expanded, giving the unit even greater flexibility.

The possibility of expansion is evident in the PLUS version and allows the fuel supply to be adjusted according to requirements and thus optimise heating comfort.

State-of-the-art combustion technology

At the heart of the boiler is a central pellet burner, which, in combination with the TSS Twin Spark System, ensures particularly efficient ignition and fuel combustion. Two alternately activated ignition elements guarantee reliable boiler operation.

Thanks to the automatic cleaning of the pellet burner and the heat exchanger, operation is sustainably stabilized, while innovative sensors, such as the negative pressure sensor, ensure a safe combustion process.

Energy efficiency and environmental friendliness

With an energy efficiency rating of A+, the EPSILON F is one of the most economical heating systems. It utilizes modern technologies, such as vertical tube heat exchangers with integrated turbulators, to achieve maximum energy efficiency.

The automatic exhaust gas and heat exchanger cleaning in combination with the particle separator not only ensures trouble-free operation but also reduces emissions, making the device an environmentally friendly heating experience.

Innovative control and ease of use

The boiler is intuitively operated via the APC Center with touchscreen, which controls both six pumps and two heating circuit mixers. This modern control system allows for easy monitoring and adjustment of heating parameters.

Thanks to the factory-installed internet module, the boiler can also be connected to a network solution, ensuring future-proof integration into modern building technology.

Security and reliability

A level sensor in the pellet hopper continuously monitors the fuel supply and automatically shuts down if the auger feeder runs out of pellets. This prevents unwanted interruptions and protects the system from damage.

Additional safety features, such as the powerful induced draft fan to stabilize combustion and the optional retrofitting of a lambda sensor, help to make operation not only efficient but also particularly safe.

Funding and additional options

The EPSILON F meets all the requirements for the BEG subsidy and BAFA requirements, making it an economically attractive alternative to conventional heating systems. The installation of a particle separator also takes into account the statutory subsidy.

Optionally, the user can receive state-of-the-art additional modules such as the GSM module, various types of room thermostats or the I-1M module to adapt the boiler to individual needs and further increase operating comfort.

Conclusion

The EPSILON F pellet boiler represents innovation and the highest standards of technology and energy efficiency. With its compact design, intuitive operation, and comprehensive safety features, it represents a modern, environmentally friendly, and economical alternative to conventional heating systems.

Whether in new construction or when modernizing existing heating systems – this advanced solution impresses with its flexibility, reliability and sophisticated ease of use, meeting even the highest demands.
