The description of the CUBA water pellet stove
The Cuba
water pellet stove is designed to heat rooms in a two-way manner, more
precisely by heating water for radiator heating in the boiler section, but to heat surrounding
space as well by emitting heat through the glass and heated surfaces, primarily smoke
channels under the boiler.
There are two types of the CUBA water pellet stove, 15 (nominal power of 15 kW) and
12 (nominal power of 20kW). The potential amount of energy transmitted to water during the
emission of gases subjected to standard is 13.8 kW and 18.3kW depending on the chosen
water pellet stove and the energy in the surrounding area is 1.4kW and 1.7kW.
The stove 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 stove water temperature
sensor, the flue gas temperature sensor, the stove airflow sensor, and other electric
equipment.
The components of hydro installation installed to the stove 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 CUBA stove uses pellets
6mm in diameter, 5-30mm in length, and 10% in terms of moisture according to the
EN14962-2 standard.
