General information
GRAND PELLET boiler, universal heating solution for halls and medium and large buildings!
The GRAND PELLET boiler is an ideal solution for medium and large buildings as well as production halls. The boiler is adapted to the efficient combustion of class C wood pallet in accordance with the PN EN 303-5: 2012 standard. It is equipped with a self-cleaning burner with a comprehensive self-cleaning system of the exchanger. Pellet lighter cooperating with the RTC clock, lighting up and extinguishing the boiler according to the schedule, reducing the number of activities to be performed at the boiler to almost zero. Thanks to the ecoNET300 internet module attached to the boiler, you can manage the boiler functions from a phone, tablet or computer.
Technology and security
Heat exchanger
Effective structure adapted to automatic cleaning of the exchanger. The design of the boiler exchanger ensures high heat removal from the furnace.
Flue outlet
The structure of the boiler has been designed in such a way that the flue outlet is at the rear. The use of such a solution in a central heating boiler allows the flue to be directly led out to the chimney.
Exhaust fan
The exhaust fan effectively supports the natural flue gas draft in the boiler.
Automatic feeder
Automatic ash removal system
Swirlers
Swirlers installed in convection ducts, connected with the automatic cleaning system, effectively reduce the speed of exhaust gas outlet. Due to systematic cleaning, the boiler maintains a constant high heat removal by the water cry. The use of automatic cleaning of convection channels contributes to the reduction of fuel consumption.
Limit switch
Steel screens

Connectivity and functionality
Simple and intuitive boiler control
Adjust the boiler operation and room temperature to your individual needs. The PLATINUM PELLET controller is programmed in such a way as to automate all processes related to the heating of your home. The owner gives the temperature he wants to have in the apartment, and the controller will optimize combustion in this respect. By entering the advanced settings of the driver, you can personalize each parameter. It all depends on the preferences of the user and household members!
Key Features:
Standard equipment
- ecoNET 300 internet module
Control the work, monitor, compare the statistics thanks to the connection of the boiler controller with the internet module. Gain access to boiler control from a mobile phone, tablet or computer. The internet module is not only a remote control, it also records and registers the course of heating the house. Thanks to the ecoNET internet module (wired, wi-fi) you can gain control over your expenses and nothing will surprise you anymore!
Additional equipment
- Lambda probe
- PLATINUM TOUCH room thermostat (touchscreen, wired)
- PLATINUM TOUCH x40 room thermostat (analog, wireless)
- PLATINUM TOUCH x80 room thermostat (touchscreen, wireless)
- Platinum B module (buffer operation control, additional two heating circuits, 2x pump, 2x mixer, 2x thermostat)
- Platinum C module (two additional heating circuits, 2x pump, 2x mixer, 2x thermostat)
Self-cleaning PPW burner
Self-cleaning PPW burner – for pellets
Quick firing up of the furnace and automatic cleaning of the furnace of ash. The burner is equipped with an automatic ceramic pellet igniter and has been designed for regular, automatic cleaning of ash. The design of the burner allows you to quickly reach a high temperature of the boiler. All functions of cleaning the furnace from ash and fuel dosage can be set in accordance with the current needs of the user.
Fuel: Pellets
Ceramic pellet lighter
Forget about manual boiler lighting. One click is enough and the automatic ceramic igniter ignites the fuel fed to the burner. Automatic igniter in conjunction with the RTC clock allows you to program the entire week of operation of the device. The device operation clock can be set separately for SUMMER and WINTER mode.
