Characteristics of BioTec-L boilers

— Boiler class 5.

— Meets the requirements for ECO design (COMMISSION REGULATION (EU) 2015/1189).

— Hot water boiler for central heating intended for firing wood logs with a moisture content

below 25% (air drying for at least 1 year).

— A modern boiler in which the principle of wood gasification (pyrolysis) thoroughly burns

fuel, thus reducing the need for cleaning to a minimum (depending on the quality of wood

and the load of the boiler).

— Design solutions for combustion gases and their additional combustion ensure a high

level of boiler efficiency, which makes it extremely economical.

— It is environmentally friendly because it achieves low levels of harmful ingredients in the

flue gases.

— Three large doors and a boiler firebox enable heating with large logs and, above all, easy

cleaning and maintenance.

— It is intended for installation in open or closed central heating systems exclusively

via buffer tanks (CAS), volume min. 50lit/kW and 3-way thermal valve at 60°C or 3-

way mixing valve with actuator.

— Delivered factory prewired with built-in boiler controller that controls the boiler.

— The factory-fitted touch screen controller controls the boiler by means of a lambda probe,

boiler combustion temperature sensor, boiler sensor, primary and secondary air intake

motor control and by changing the speed of the pressure fan at the flue gas outlet of the

boiler. The controller can also control 1 heating circuit with mixing valve and DHW circuit.

— Possible upgrade with web monitoring and management, and heating modules for

controlling up to max. 8 heating circuits via mixing valves according to outdoor or room

temperature (accessories).

— TheboilerhasbeentestedandcertifiedaccordingtoEN303-5andmeetsclass5and

is manufactured in accordance with ISO 9001 and ISO 14001.
