Wood heating boilers BioTec-C (25/35/45 kW)
BioTec-C steel hot water boilers (with nominal heat output of 25 to 45 kW) are designed
for wood log fuel firing for the heating of small and middle sized premises. The wood
gasification principle enables a complete fuel burning. Logs up to 550 mm long can be
inserted into the large combustion chamber. The burning period for a single fill of logs is
at least 4 hours at the rated output and can be extended to a whole day if the need for
heating is less.
The boiler can keep the glow even 8 hours, which means that in this period it is not
necessary to fire up the boiler in order to keep the heating process. Boiler operation is
managed with inbuilt boiler control unit using the boiler temperature sensor and
changing the rpm’s of underpressure fan on flue gases outlet from boiler. Boiler is
connected to the central heating system through a 3-way thermostat valve accumulation
(buffer) tank (like CAS, CAS B, CAS S, CAS BS).
The boiler is tested and certified according to the European standard EN 303-5:2012
and meets class 5. It is manufactured in compliance with ISO 9001/2008 and ISO
14001/2004 standard and meet the requirements for ECO design (commission (EU)
2015/1189)
HEATING TECHNIQUE
Economical
Pyrolytic combustion makes it possible to use more than 85%, which saves considerably compared to classic wood boilers.PRODUCT CHARACTERISTICS:
WiFi READY
Digital boiler control supports Internet monitoring and control of boiler operation via the internet portal.One charge per day
The duration of a single charge is at least 4 hours full power with the possibility of prolonging the entire day if the need for heating is reduced.Large size wood
Large firebox allows wood to burn up to half a meter long.

•
It is delivered pre-wired with the built-in boiler control unit to control the boiler.
•
The built-in boiler control with the colour touch screen manages the boiler operation using the lambda probe, temperature sensor in the boiler
combustion chamber, boiler sensor, motor for the management of primary and secondary air intake and changing the rpms of underpressure
fan on the flue gases outlet from the boiler.
•
Possible upgrade of the GSM alarm and the module for steering up to max.8 heating circuits via mixing valves to the outside or room
temperature (additional equipment).
•
In addition to the operation of the boiler, the boiler pump and the return flow (through the 3-way mixing valve and the return sensor), the
control unit can manage the filling of the accumulation tank and heating of the domestic hot water tank (DHW sensor) (sensor + pump).
•
Easy transportation and leveling by 4 adjustable legs of the boiler.
•
The boiler is tested and certified according to EN 303-5: 2012 and meets Class 5. It is manufactured in accordance with ISO 9001 and ISO
14001 standard.
BASIC DIMENSIONS:
Obligatory additional equipment:
– accumulation tank for heating system (CAS (minimum 30 lit/kw boiler
power)), 3-way thermostat valve, like ESBE LTC 141; (closed heating
system) – thermal safety valve, safety-airvent group (2,5 bar) and
expansion vessel; (open heating system )
– open expansion vessel.
•
Boiler Class 5.
•
Meet the requirements for ECO design (COMMISSION (EU)
2015/1189).
•
Hot water boiler for central heating systems is engineered for wood log
firing of the moisture content under 25% (min 1 year long air dried
wood).
•
The wood gasification principle enables total burning of the fuel,
reducing the cleaning of the boiler to minimum (depends on wood
quality and nominal boiler load).
•
The design and construction, including the wood gasification principle
of complete burning assures high efficiency and makes the boiler
extremely economical.
•
It is environmentally friendly because of extremely low concentration of
harmful components in flue gases.
•
Three doors and the combustion chamber enable loading with large
logs as well as very simple cleaning and maintenance.
•
It is engineered for installation in open or closed central heating
systems only through accumulation tanks (CAS), volume min. 50l/kW
and a 3-way thermal valve at 60°C.
NSTALLATION EXAMPLE:
*The internal diameter and height of the chimney must be strictly in line with the
boiler's nominal capacity. It must comply with all national regulatory documents
and manufacturer's recommendations.
