It is a stove with 8 kW of nominal thermal power, which uses wood pellets as fuel, whose operation is totally independent of a connection to the electrical network. The combustion air supply system is natural draft. The transmission of heat from the combustion products to the environment is given by radiation and natural convection. The pellets are fed to the combustion chamber by means of an innovative mechanism with very low power consumption, whose operation combines the action of gravity (weight of the stored pellets) and the continuous movement of a dosing roller driven at constant speed by means of a direct current electric motor powered by a battery, which recharges autonomously using an automatic system composed of a panel of photovoltaic solar cells and an adjustable switching output source. With the recharging system disconnected, the pellet feeding mechanism has an autonomy of more than 170 continuous hours of operation at nominal thermal power. Using the automatic recharging system, and estimating 5 hours / day of useful sunshine, autonomy increases exponentially, reaching more than 2 years of continuous operation.
The design of the stove converts it into a heating system that uses only renewable energies, combining the energy coming from biomass and photovoltaic solar energy.
The NATURE stove was born with the aim of covering the heating demands of any medium-sized residential or commercial premises, for people highly committed to caring for the environment, reflected in the use of only renewable energies such as: energy coming from the combustion of biomass (wood pellets) and photovoltaic solar energy. Moreover, its complete independence from the electricity network makes it the best option to be used in places where the electricity supply network is deficient, or even non-existent.
The simplicity, both in the start-up and operation, and in its maintenance, make the NATURE stove a product that is very easy to use, without the user being required a high dose of technical knowledge, converting it into a product whose functionality is at reach, practically, of any user.
