Ceramic pellet stove, air, ducted and hydro versions

Pellet stove with steel structure, ceramic top and sides. Cast iron brazier. Intelligent combustion management with Maestro+. As one of the most popular MCZ products, this stove is available in Air, Comfort Air® and Hydro Matic versions, all characterised by a broad and natural flame, sealed structure, weekly-emptying ash pan, ceramic spark plug for quick three-minute ignition.

A stove that is almost a boiler: all the heat your system needs

This is a hydro stove, which not only heats the air in the room, but also the water in the heating system. It is ideal whether you have normal radiators or an underfloor heating system in the house. The optimal efficiency of this stove allows you to have the whole house warm in a few minutes. More than 90% of the stove's power output is transferred to the water in the system. There is also a front fan, which is useful for maintaining comfort in the room where the stove is installed.

Cleaning autonomy

With this product, the capacity of the ash pan has been increased to almost 5 litres and the capacity of the ash compartment to more than 8 litres, which means about one week of stove operation. Plus, the Hydro Matic and Comfort Air Matic versions feature an automatic scraping system that prevents ash build-up and avoids having to clean the firebox every day.

Ignition speed

Thanks to a new ceramic spark plug, the flame appears in less than three minutes, with a 40% reduction in ignition times and a significant cut in electrical consumption.

“Brushless” gear motor

The new patented “brushless” gear motor has been made exclusively for MCZ and it is used in the pellet loading feed screw and in the automatic brazier cleaning system. Compared to traditional gear motors, it is more powerful, more noiseless and less energy-hungry (electric consumption reduced by 90% compared to conventional motors).


Advanced control via Wi-Fi with digital panel included as standard

Thanks to Maestro+ technology, the stove can be controlled directly from a smartphone, via a specific App, which provides full control either at home or away, by connecting via the home internet network (router) or directly via Bluetooth. An innovative retractable digital control panel fitted on the top is also available as standard.
