Wood boiler HEFAISTOS P1

log-burningresidentialindoor

Output: 30 ~ 100 kW Fuel: firewood Advantages: - long service life of the cast-iron heat exchager - environmentally friendly operation - Class 3 according to EN 303-5 - combustion efficiency 83-89% - threaded flanges for easy installation - output by number of sections Characteristics Hefaistos P1 is a pyrolytic sectional cast-iron boiler for burning firewood in systems with forced circulation of heating water. It reaches high output and meets Class 3 of EN 303-5. Corrosion-proof cast iron-material is used for heat exchanger and fire chamber base. Stainless steel linig is used for upper fuel chamber. Control unit ST 81 is used for the electronic version "E" (3-5 sections) and collects data from return water, heating water and flue gases temperature sensors using Hall sensor for modulating exhaust fan. Thermostatic version "T" (6-7 sections) uses working, flue gases and pump thermostats to control the boiler operation. In case the output of the boiler does not correspond to the projected heat loss of the heated object it is necessary to extend the heating system by connecting the storage tank (about 25 litres for each 1 kW of boiler output) or four-way mixing valve located behind the boiler.
