Features

CONVENIENCE

Silent and easy to use for inexperienced users. The boiler simply requires adding fuel to the storage tank. No ash removal is required. A self-cleaning burner transfer the ash to the built-in ash collector cleaned by our service engineer as part of an annual inspection. Intuitive room thermostat for boiler control as standard. Optional remote control using a smartphone or a desktop app with an interface similar to the room thermostat interface.

 

AUTONOMY

  • Mini Matic adapts its performance to the variations in quality of certified fuel (A1, A2) and adjusts the parameters accordingly.
  • An energy-efficient device with advanced auto-diagnostics systems preventing shut-down.
  • Mini Matic features a redundant start-up system.

 

AUTOMATIC RESTART

If the boiler shuts down due to empty fuel storage tank, simply add fuel - the boiler with restart automatically and continue heating using previous settings.

 

MODERN DESIGN 

A boiler with a built-in burner, storage tank, fuel feeder and ash collector enclosed in a uniform, modern housing.

 

UNIQUE SYSTEMS

  • Advanced boiler management system logics sets the optimal parameters and is compatible with other KOSTRZEWA devices - Mini Matic is compatible with our new products - heat pump and heat recovery ventilation unit. All devices can be controlled by a single controller.
  • OMS − fuel level measurement including low fuel reserve (patented KOSTRZEWA solution).
  • Flue draft monitoring and optimizing system
Tests and certificates

All our boilers are tested by an accredited testing laboratory - a member of the international Association of Accreditation.

 

The test results show that KOSTRZEWA products meet the emission requirements laid down in the Ecodesign Directive and guarantee user safety.

 

All boiler types undergo over 20 different tests including:

  • Boiler pressure test at 4 bar
  • Energy-efficiency and emission tests at 10%, 11% and 13% fuel oxygen content
  • Power input test in operation and standby mode
  • Functional closed-loop tests without auxiliary safety devices

 

Our boilers are included in the list of devices covered by the eco boiler grant schemes in many EU countries.

PELLET is a processed waste timber compressed under high pressure without use of any bonding agents.

 

PELLET CLASSES TO PN-EN ISO 17225-2:2014-07:

A1 - ash content ≤0.7% Premium quality product
A2 - ash content ≤1.2%
B - ash content ≤2%
 

PELLET - eco-friendly, high-energy clean fuel!

 

Operating and monitoring system for solid fuel boilers. Our boilers are fitted with a system monitoring fuel level in the storage tank and the amount of ash in the ash pan to guarantee convenient and comfortable operation. In many boilers without a similar system available on the market user must remember to refill fuel and remove ash regularly. The system, developed by KOSTRZEWA, measures and notifies the user in advance on required actions (fuel refilling or ash removal). Notifications are displayed on a boiler controller screen and a room temperature controller screen. Our solution is patent protected.
