BioTec II
BioTec II – modern wood heating technology
BioTec II steel hot-water boilers (25–45 kW) are designed for the efficient and eco-friendly heating of family homes and medium-sized buildings. Thanks to pyrolysis technology, they achieve high fuel utilization and reliable operation.
The large combustion chamber accommodates logs up to 500 mm in length, while a single load ensures long-lasting operation and great ease of use. The boiler is equipped with a digital control system featuring a 7-inch touchscreen and a lambda probe that optimizes the combustion process for maximum efficiency.
When combined with a CAS accumulation tank, the BioTec II ensures even greater energy efficiency, additional savings, and stable heat throughout the entire heating season.
-
WOOD SAVING
Pyrolytic combustion enables efficiency of more than 85%, which results in significant savings compared to classic wood-fired boilers. -
WiFi
The digital regulation of the boiler supports online monitoring and control of the operation of the boiler through an internet portal. -
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: High operating efficiency and low harmful emissions, compliant with current European standards.
-
New generation pyrolytic combustion: Advanced technology ensures maximum energy extraction from wood with reduced fuel consumption.
-
Long burn time: A single load allows for at least 4 hours of operation at nominal heat output, with significantly longer run times during periods of lower heating demand.
-
Ember retention for up to 8 hours: Allows for reloading without re-ignition, enhancing user convenience.
-
Spacious combustion chamber: Designed for logs up to 500 mm in length, facilitating easier handling and less frequent reloading.
-
7" touchscreen control: A multifunctional touchscreen display enables simple and intuitive system management.
-
Lambda probe for optimal combustion: Continuously monitors the combustion process and automatically adjusts boiler operation for maximum efficiency.
-
Heating system control: Standard configuration supports the management of up to two heating circuits, or one heating circuit and domestic hot water preparation.
-
WiFi connectivity: A built-in WiFi module enables monitoring and control of the heating system via smartphone, tablet, or computer.
-
CAS accumulation tank: When combined with a thermal storage tank, it achieves maximum efficiency, additional savings, and superior heating comfort.
