The UNI 25
water boiler is designed to heat by heating water for radiator heating in the
boiler section.
The boiler is comprised of assemblies whose basic components have to be delivered in
a standard version:
The boiler part with turbulators and smoke channels, the dosing silo, the external
plating, the door with a glass-ceramics component.
The display, the automatic controls panel, the electric gear motor of the pellets
transporter, the flue gas fan, the safety pressure switch, the boiler water temperature
sensor, the flue gas temperature sensor, the boiler airflow sensor, and other electric
equipment.
The components of hydro installation installed to the boiler are: the circulating pump,
the 10-liter expansion vessel, the safety pressure valve, the air vent, the tap for charging and
discharging the exchanger.
Wood pellets are 100% made from cellulose. Subjected to pressure, wood remnants are
compressed into pellets 6mm in diameter and 2-3cm in length. Pellets should be properly
stored in a dry place in order to ensure efficient combustion. The
UNI 25
boiler uses pellets
6mm in diameter, 5-30mm in length, and 10% in terms of moisture according to the
EN14962-2 standard.
