EPSILON F – Compact pellet boiler with central pellet burner

Product overview

The EPSILON F pellet boiler impresses with its compact design, yet still provides all the essential features. With its central pellet burner and modern technology, it offers maximum efficiency and ease of use for a reliable heating experience.

The features are first-class: In addition to automatic heat exchanger cleaning and ash removal, the boiler ensures trouble-free operation. Thanks to the optional pellet hopper expansion in the PLUS version, operation can be flexibly adapted to individual needs.

Innovative combustion technologies

At the heart of the boiler is a central pellet burner, ensuring particularly efficient combustion. The TSS Twin Spark System, with two alternately activated ignition elements, ensures fast and reliable ignition, resulting in consistent power output.

The vertical tube heat exchangers with integrated turbulators ensure maximum energy yield, while the negative pressure sensor and the powerful induced draft fan ensure the necessary negative pressure in the combustion chamber and boiler.

Modern operating concept

The EPSILON F is controlled via the modern APC Center with touchscreen, which enables intuitive operation. This control system controls six pumps and two heating circuit mixers and also offers the option of using the Internet mode as standard.

An integrated level sensor in the pellet container always shows the current fuel reserve and automatically interrupts operation if the pellet supply runs low to ensure optimal operation.

Modular expandability

The pellet boiler impresses not only with its extensive standard features but also with the option of optional upgrades. A lambda probe, for example, can be added to make combustion even more efficient and environmentally friendly.

In addition, additional accessories such as GSM modules and various room thermostats are available, which expand the range of applications and further optimize operation.

Energy performance and extraction technologies

With power variants ranging from 10, 15, 20, and 25 kW, the EPSILON F is used in a wide variety of applications. The high energy efficiency rating of A+ underscores the system's cost-effectiveness and future-proofing.

Thanks to special support mechanisms, including a particle separator, the boiler also qualifies for subsidy programs. This technology not only supports safe operation but also optimizes the environmental compatibility of the heating system.
