EPSILON F – Compact pellet boiler with central pellet burner

Product overview

The EPSILON F pellet boiler impresses with its compact design, yet it still provides all performance-relevant functions. 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 expansion of the pellet hopper volume 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 that ensures particularly efficient combustion. The TSS Twin Spark System with two alternately activated ignition elements guarantees rapid and reliable ignition, resulting in a constant 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 allows for intuitive operation. This control unit manages six pumps and two heating circuit mixers and also offers the option of using internet mode by default.

An integrated level sensor in the pellet container always shows the current fuel reserve and automatically interrupts operation should the pellet supply run low, in order to guarantee optimal operation.

Modular expandability

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

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

Energy performance and conveying technologies

With power outputs ranging from 10, 15, 20 to 25 kW, the EPSILON F is suitable for a wide variety of applications. Its high energy efficiency rating of A+ underscores the system's cost-effectiveness and future-proof design.

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