Wood pellet boiler
Description
Ninfa is the new pellet boiler with self-cleaning brazier; represents a practical solution with respect to methane, diesel and LPG fueled systems. It offers a considerable saving in management costs (up to 70%) significantly reducing COanti polluting emissions.
Advanced electronics allow the possibility of integrating it with new and existing systems. Small and compact, it can be installed in technical rooms with limited space, is ready for use and can be connected directly to the system.
It is available in 2 models. The construction materials make the boiler resistant to high temperatures, ensuring a long life.

Self-cleaning of the brazier
The new Ninfa model is standard equipped with patented self-cleaning burner.
The automatic mechanism ensures perfect cleaning of the brazier at startup of the boiler, ensuring a good ignition.
In this way, it is not necessary to empty the burner every day, but only every 700 / 1000 kg of pellet burnt.
The self-cleaning system also improves the efficiency of the boiler, as before the new ignition the brazier remains clean while maintaining the optimum combustion conditions.
Safe pellet feeding system
Pellet boilers are equipped with a Nymph secure system of the pellet feed. This closure system swivel, allows to dose in a precise manner the amount of fuel released into the combustion chamber.
Its safe operation avoids that the machine could shut down during the pellet loading, also improving the safety of the system, because the combustion chamber is hermetically closed in all its phases excluding the backfire
With this technical measure all the heating system is more stable and the boiler much more clean and quiet.

High heat exchange with the flue
For optimal performance, in addition to the heat of the fire, Ninfa also exploits the one produced by the fumes thus having an outstanding performance.
The fumes coming from the combustion chamber to pass through the pipes for the heat exchange releasing their heat.
Once at the top, the smoke bouncing on the cover of vermiculite and are channeled back on other pipes releasing until the last layer of warmth.
The stored heat is transmitted to the conduits and used for heating or for the production of sanitary hot water.
Cleaning system efficient
The new boiler has been designed by taking technical precautions to ensure a simple and effective cleaning of the tubes and the maximum efficiency of the boiler avoiding costly maintenance.
By moving the handle (removable) located above the boiler, the springs run down the exchange system and remove easily any residual soot from the walls of the ducts.
The soot falls then the collection tank located behind the ash tray and can be removed with a vacuum cleaner.
Ash compactor and large tank
Ninfa has been designed to ensure maximum independence and efficiency of operation.
the pellet tank can contain up to 85 or 170 kg of fuel with the expansion module for a range of up to 120 hours of operation.
Combining the compactor optional ash pan you get to empty the ashes every 1500 kg of burnt pellets.
Advanced electronic management
Ninfa is the pellet boiler of the latest generation was designed with systems and technologies.
One of the pluses is its electronic management system that optimizes the combustion by setting the terms of use and installation.
Everything is handled electronically by the programmable thermostat which also regulates the operation, planning and management of the water temperature.
Ninfa is synonymous with comfort and energy savings.

The Ninfa boilers have been designed with the precise aim to exploit the calorific value of the pellet and minimize the percentage of heat discharged with the fumes.
The fumes coming from the combustion chamber are conveyed through two manifolds to a heat exchanger consisting of 10 pipes in which the fumes, going back with helical and turbulent flow, give up heat to the water.
The heat exchange is enhanced by specially sized fans to promote a greater push the fumes along the 16 pipes.
Automatic pellet feeding system
For proper operation, the boiler should be positioned in a utility room in which drain into at least as much air as is required for regular combustion: we should have in the local opening with a free passage of at least 6 cm2 for each kW of installed power . The minimum cross section of the opening must not be less than the 100 cm2.
The Ninfa boilers must be properly connected externally to allow the smoke outlet into the atmosphere: the discharge must necessarily take place on the roof and not a wall or into an enclosed space with clear sky.
