The Bio-Tec steel hot water boilers (nominal heat output 25-45kW) are designed for wood fired heating of small to medium sized premises. The wood gasification principle ensures complete burning. Thanks to the big combustion chamber wood pieces of up to 550 mm long can be inserted. The burning period for a single loading is at least 4 hours at full nominal boiler output and this can be extended to the whole day at lower heating demand. The boiler can even stay alight for up to 12 hours. The fitted boiler controls regulate the boiler’s functioning.
The boiler is connected directly to the central heating system through a 3-way thermostat valve and a CAS accumulation tank.
SUITABLE FOR THE ENVIRONMENT
Low emission of harmful compounds in the flue gases.
The principle of pyrolysis burns fuel thoroughly to achieve maximum efficiency.
One charge is at least 4 hours at the nominal heat output – the possibility of prolonging the whole day if the need for heating is reduced.
The spacious combustion chamber allows fueling up to 550 mm in length.
Hot water boilers for central heating systems is designed for wood log firing (moisture content under 25%).
The wood gasification principle enables total burning of the fuel, reducing cleaning of the boiler to minimum (depends on wood quality and usage of the boiler).
Their construction, the flue gas solution and their additional burning enables a high efficiency rate and makes operation very economical.
Ecologically acceptable because of extremely low concentration of harmful components in the flue gases.
The three large doors to the combustion chamber enable particularly simple cleaning and maintaining, as well as loading with substantial logs.
Delivery includes the pre-wired control system, boiler regulator and room thermostat with indication of the need of wood replenishment.
The boiler regulator controls the firing process through a circulation pump in the first circuit (boiler-accumulation), a circulation pump in the heating circuit (accumulation-radiators) and a sanitary water circulation pump and gives the information back to the control system and room thermostat about the need of log refills.
It is engineered for installation in open or closed central heating systems only through accumulation tanks (CAS), volume min 50 l/kW and a 3-way thermostatic valve at 60°C.
The boiler is tested and certified to the European standard EN 303-5 and manufactured in accordance with ISO 9001 and ISO 14001 standard.
