Multifuel Heating Boiler PROSAT MULTI EKO 20 kW with feeder on left side

PROSAT MULTI EKO – Advanced Multifuel Boiler with Intelligent Control System

PROSAT MULTI EKO is a modern hybrid heating boiler designed for residential and commercial heating applications. Its multifuel capability provides maximum flexibility and reliable operation regardless of fuel availability. The boiler supports fully automatic combustion of eco pea coal and wood pellets, as well as manual firing with coal and firewood. The hybrid design allows both automatic and manual operating modes, enabling the heating system to be tailored to the user's requirements.

Key Features

• Automatic combustion of eco pea coal and wood pellets.
• Manual firing with coal and firewood.
• Advanced automatic combustion control algorithm.
• Stable operation using a proportional (P) control algorithm.
• Large full-color TFT/LCD display.
• Domestic Hot Water (DHW) control in Summer and Winter modes.
• Control of mixing valves and circulation pumps.
• Expandable to control up to five mixing heating circuits.
• Compatible with room thermostats and room control panels.
• Remote Internet access via the Media Bord 300 module.
• High thermal efficiency thanks to the rear-pass heat exchanger design and flue gas turbulators.

Next-Generation Boiler Control System

The boiler is equipped with an advanced controller designed specifically for hybrid heating systems. The controller supports four operating modes:

• Eco pea coal
• Wood pellets
• Firewood
• Coal

Stable boiler operation is ensured by a modern proportional P control algorithm, which precisely regulates boiler output, minimizes temperature fluctuations, and maximizes combustion efficiency. The controller continuously analyzes operating parameters and automatically adjusts boiler performance according to the current heating demand.

Automatic Combustion Control

The boiler incorporates an advanced automatic combustion control algorithm developed through many years of engineering experience and cooperation with scientific research institutions. The system combines expert knowledge with modern computational methods to automatically determine the optimum combustion parameters.

Dynamic combustion control enables the system to:

• Maintain stable system temperatures.
• Automatically adjust boiler output to the building's heat demand.
• Reduce fuel consumption.
• Lower pollutant emissions.
• Extend boiler service life.

Fully Automated Operation

The controller manages every major stage of the combustion process. In automatic mode it performs:

• Automatic ignition.
• Automatic fuel feeding.
• Maintaining the programmed boiler temperature.
• Continuous combustion process control.
• Ongoing monitoring of the complete heating system.

Large TFT Display with Intuitive User Interface

The controller features a large full-color TFT/LCD display with an intuitive user interface. All boiler and heating system operating parameters are presented clearly, ensuring convenient day-to-day operation.

Advanced Heating System Management

The controller offers comprehensive management of central heating and domestic hot water production.

• DHW operation in Summer and Winter modes.
• DHW priority or non-priority operation.
• Connection of a room thermostat.
• Support for an optional room control panel.
• Continuous monitoring of system operating parameters.

Mixing Valve Control

As standard, the controller supports one mixing valve circuit. With dedicated expansion modules, the system can control up to five independent mixing valves. The controller is compatible with both three-way and four-way mixing valves used in radiator and underfloor heating systems.

Controller functions include:

• Control of 3-way and 4-way mixing valves.
• Support for radiator and underfloor heating installations.
• Weather-compensated or standard control operation.
• Mixing valve circulation pump control.

Remote Internet Monitoring

When equipped with the Media Bord 300 module, the controller can connect to the Internet, allowing convenient remote monitoring and management of the boiler from virtually anywhere.

Modern Boiler Construction

PROSAT MULTI EKO has been engineered using modern heat exchanger technology to maximize thermal efficiency. The rear-pass heat exchanger design combined with integrated flue gas turbulators improves heat transfer, increases combustion efficiency, and reduces overall fuel consumption.

Technical Specifications

Can the PROSAT MULTI EKO boiler switch between different fuels without replacing the unit?

Yes. One of the greatest advantages of the PROSAT MULTI EKO is its ability to operate with multiple fuel types depending on current requirements and fuel availability. The boiler automatically burns wood pellets and eco pea coal, while the manual firing mode allows efficient combustion of firewood and coal. This versatile solution provides excellent independence from fluctuating fuel prices and enables users to choose the most cost-effective heating option for each heating season without replacing the boiler or carrying out expensive modifications to the heating system.
