Boiler Metal-Fach GRAND PELLET 34 kW
GRAND PELLLET is adapted for efficient combustion of different quality biomass, and self-cleaning burner together with an automatic self-cleaning boiler exchanger system, which significantly reduces frequency of boiler cleaning.
Fuel: Pellet
Pellet is an ecological fuel that is produced by pressing wood waste such as sawdust or shavings. It is fully natural, thus burning does not produce harmful compounds into atmosphere.
Internet module ecoNET
Communication module cooperating with PLATINUM controller enables servicing, operation and management of boiler using a computer, tablet or cell phone via an intuitive website www.econet24.com. Thanks to built-in web server in ecoNET module, it is possible to remotely manage boiler operation in local network without access to Internet.
Self-cleaning
Burner is equipped with a mechanism that cleans itself from ash on its own and regularly, so there is no need to clean it.
Exhaust fan as standard
This solution gives us a greater possibility of configuration, which helps to optimize it.
Automatic feeder
The controller, on the basis of measurements from combustion sensors, recalculates the fuel demand and regulates its appropriate amount. Thanks to this, the combustion process is economical, ecological and does not require any additional user service.
Vertical convection channels
Construction of boiler exchanger ensures a high heat reception from furnace. Steel screens and swirls have been installed in body, which delay air outlet, which results in collection of more heat by central heating circuit.
Steel screens
Steel screens raise temperature in tcombustion chamber and stop particles floating over fireplace, burning them. As a result, thermal efficiency of furnace is increased and outgoing flue gases are much cleaner.
Mechanized self-cleaning system of exchanger
Thanks to exhaust gas swirlers that are connected to geared motor, boiler is able to self-clean unwanted soot deposited in convection channels. We can configure cleaning frequency via controller display.
A screw system for removing ash from the inside of the boiler
Augers have been used for boiler, which are responsible for removing ash from boiler to outside. Ash is transported to special sealed containers. This ensures that boiler maintains right parameters.
Ash collection containers
Combustion residues are discharged into specially designed containers placed on the side of boiler. Containers are tightly fixed to boiler structure, preventing dust from getting outside. It is enough to empty containers once every few weeks to keep inside of boiler clean.
