Features

ECONOMY

Innovative Platinum Bio VG burner automatically adjust its parameters to the building’s heat demand by increasing or decreasing its size (variable burner grate length). The burner design uses a variable geometry (VG) technology. Patented in the Polish Patent Office.

 

EXTREMELY DURABLE

All our devices undergo a series of tests to verify the flow rates, strength and stresses followed by long-term strength tests in a laboratory.

 

SAFETY

Twin Bio Luxury boiler features OMS for boiler and burner condition monitoring. When the controller receives information about any irregularities, the device is disabled and a message is displayed on the boiler controller or the weather compensator screen.

 

RELIABLE SERVICE
We maintain an extensive service network. Over 200 qualified service engineers provide warranty and post-warranty services in Poland and abroad.

 

INTERNET MODULE
All boiler and central heating system functions can be remotely monitored using a PC or a smartphone (optional).

 

A COMPLETE HEAT SOLUTION 
Even the best boiler isn’t enough. We offer complete boiler room and heating system solutions. We offer advanced solutions including pellet storage, pneumatic fuel feeding, cascade automation, weather compensated CH system control, DHW and buffer tank control, return protection, fuel and ash sensors, heat pump, solar panel and gas boiler control.

Tests and certificates

Our boilers are tested by an accredited testing facility - a member of the international Association of Accreditation.

 

The test results show that KOSTRZEWA products meet the emission requirements laid down in the 5 class 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 oxygenation
  • Energy consumption test in operation and standby mode
  • Operational test in a closed loop system without auxiliary safety devices
     
    Our boilers are included in the list of devices qualifying for a subsidy in many EU countries.
  KOSTRZEWA PLATINUM BIO VG BURNER - burns pellets : A1, A2, B

KOSTRZEWA PLATINUM BIO VG BURNER - burns pellets : A1, A2, B

Compatible with certified class A1 pellet and economy class A2 and B pellet. Regular slag (cinder) removal is no longer needed even with low quality pellets. The burner is cleaned automatically in a continuous operation mode. Platinum Bio VG burner is patent protected (patent no. 228615, Patent Office of the Republic of Poland).

  OMS (operating monitoring system)

OMS (operating monitoring system)

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.

  PELLETS VACUUM (PNEUMATIC PELLET FEEDER)

PELLETS VACUUM (PNEUMATIC PELLET FEEDER)

A virtually maintenance-free pneumatic device feeding pellet at a large distance from the storage area directly to the boiler including multiple sensors for a fully automatic operation.  If MINIMUM level is detected in the buffer tank, it is immediately refilled to the MAXIMUM level. The device can also be timer programmed, i.e. the buffer tank will be refilled to the MAXIMUM level at a pre-set date and time.

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!

Ceramics is everywhere - the combustion chamber, the heat exchanger and the burner are coated with advanced ceramics to improve the combustion process and efficiency and to reduce the emission. During operation, the ceramics heats up to over 1,000°C to improve the biomass combustion efficiency.

 

Flue gas vortex generators retain energy inside the boiler.
