Compact pellet boiler EPSILON F for efficient heating solutions

EPSILON F – Compact pellet boiler with central pellet burner

Product overview

The EPSILON F pellet boiler combines state-of-the-art technology with a compact design, offering a future-proof alternative to fossil fuels. Its high-quality features and innovative functions ensure efficient and environmentally friendly operation.

The device is available in various power ranges (10, 15, 20, and 25 kW) and meets the highest energy efficiency standards within Class A+. The pellet hopper capacity can be optionally expanded using the PLUS version.

High-quality equipment

Equipped with a central pellet burner and automatic heat exchanger cleaning, the focus is on an advanced operating concept that minimizes maintenance while maximizing efficiency. The integrated ash removal system supports continuous, trouble-free operation.

A BEG-compliant particle separator and the option of retrofitting a lambda sensor ensure not only a particularly clean combustion process but also environmentally friendly use.

Innovative combustion technology

The EPSILON F pellet boiler utilizes state-of-the-art combustion technology – the TSS Twin Spark System ensures reliable and efficient combustion with two alternately activated ignition elements. This results in optimal fuel utilization and consistently high energy yield.

Further technical highlights such as vertical tube heat exchangers with swirlers and a strong induced draft flow rate ensure that heating performance and safety are always in balance.

Comfortable operation

The intuitive control via the APC Center touchscreen makes operating the boiler simple and user-friendly. The integrated control system controls up to six pumps and two heating circuit mixers, enabling precise control of all processes.

A factory-installed internet module enhances ease of use and allows connection to modern remote control systems – ideal for users who want to keep an overview even from a distance.

Security and surveillance systems

A vacuum sensor in the combustion chamber and a strong suction force from the fan ensure that the required negative pressure is maintained at all times. Furthermore, a fill level sensor in the pellet hopper prevents the auger from running empty, thus protecting the system.

These integrated safety features not only increase operational safety but also contribute to the longevity and reliability of the boiler.

Energy efficiency and promotion

With its high energy efficiency and innovative technology, the boiler not only ensures a cost-effective heat supply but also meets modern ecological requirements. This makes it an excellent choice not only from an economic but also from an environmental perspective.

The possibility of BEG funding underlines the aim of promoting future-oriented and sustainable technologies.

Expansion options and accessories

In addition to the standard version, the boiler can be upgraded with additional accessories. These include communication modules (GSM, internet, and radio modules) as well as additional control units such as various room thermostats.

The expandable PLUS version with an enlarged tank also allows for a longer fuel reserve, which further increases the ease of use and flexibility of the system.
