BioTec-C
BioTec-C is a pyrolytic steel hot water boiler for central heating, developed for extremely efficient wood burning. With a nominal heat output of 25 to 45 kW, it is ideal for heating small and medium-sized buildings. Thanks to pyrolysis technology, the fuel burns thoroughly, with a high degree of utilization and reduced emissions.
The spacious firebox allows burning logs up to 550 mm long, and one charge allows the boiler to operate for up to 4 hours at full power - or even longer, when the heating needs are less. The boiler maintains the embers for up to 8 hours, which makes it easier to continue burning without re-igniting. The operation is controlled by the factory-installed regulation through the temperature sensor of the boiler and flue gases and the speed regulation of the vacuum fan of flue gases. It is intended for installation in central heating systems via a three-way thermostatic or mixing valve with an accumulation tank (CAS).
Certified according to EN 303-5:2012 (class 5), manufactured in accordance with ISO 9001 and ISO 14001 standards, and meets EU ECO design requirements (Commission Regulation (EU) 2015/1189).
-
WOOD SAVING
Pyrolytic combustion enables efficiency of more than 85%, which results in significant savings compared to classic wood-fired boilers. -
BUILT-IN REGULATION
The factory-installed control unit with a display and 4 buttons controls the boiler using a boiler sensor and a flue gas temperature sensor. -
ONE CHARGE PER DAY
The duration of one charge is at least 4 hours at full power, with the possibility of extending it to the whole day if the need for heating is reduced. -
LARGE TIMBER
The large fire pit allows you to burn wood up to half a meter long.
Product characteristics
-
Class 5 boiler: Meets the highest European energy efficiency and emission standards, in accordance with the EN 303-5:2012 standard.
-
ECO design: A responsible choice for the environment Fully compliant with Commission Regulation (EU) 2015/1189 on ecodesign.
-
Wood heating: Designed for burning dry logs (moisture < 25%, air-dried for at least 12 months), ensuring optimal combustion and lower consumption.
-
Pyrolytic combustion for minimal: cleaning Advanced wood combustion reduces the amount of ash and the need for regular cleaning - all provided that quality fuel and proper boiler load are used.
-
High efficiency with smart flue gas management: Optimized gas flow and combustion significantly increase boiler efficiency and reduce fuel consumption.
-
Low emissions: clean flue gases, a clear conscience Environmentally friendly, with minimal emissions of harmful components in flue gases.
-
Affordable and robust firebox: Three doors and a spacious firebox enable the burning of larger logs, as well as easy cleaning and maintenance.
-
Installation via CAS system: Designed for connection to open or closed central heating systems exclusively via accumulation tanks (min. volume according to local regulations) and a three-way thermal valve set to 60 °C.
-
Control electronics included as standard: The boiler comes factory-wired, with an integrated control unit that precisely controls its operation.
-
Easy control via display and 4 buttons: The control unit uses data from the boiler sensor and flue gas temperature sensor and dynamically adjusts the speed of the flue gas pressure fan for optimal operation.
-
Multi-zone control: In addition to controlling the boiler operation and return line protection (via a 3-way mixing valve and sensor), the control unit allows filling of the accumulation tank and can control the preparation of domestic hot water (DHW).
-
Ease of transport and installation: 4 adjustable feet allow easy leveling of the boiler during installation.
-
Verified quality and safety: Certified to EN 303-5:2012 (Class 5) and manufactured in accordance with the international quality and environmental standards ISO 9001 and ISO 14001.
