Features

ECONOMY

We offer a unique product - a miniature boiler with many advantages. With its variable geometry Platinum Bio VG burner - innovation on a European scale - Mini Bio Luxury can be used with all types of pellets (class A1, A2 and B) and pellet/oat hull mix.   Ceramic inserts in the burner and heat exchanger improve boiler efficiency and keep fuel consumption to a minimum.

 

RUN AND FORGET

Our boilers are virtually maintenance-free to guarantee the highest comfort of operation. Automatic boiler start-up and shut-down with fuel level and ash content monitoring and notification in advance when fuel refilling or ash pan cleaning is required. The number of visits to the boiler room can be kept to a minimum.

 

DURABILITY

High quality steel and the highest quality components guarantee many years of failure free operation. All new models are thoroughly tested for many months before marketing. All our boilers are individually tested for durability at min. 4 bar - a feature hardly ever found elsewhere.

 

RELIABLE SERVICE

We maintain an extensive service network. Over 200 qualified service engineers provide warranty and post-warranty services in Poland and abroad. Service can be arranged using our internet platform at www.serwis.kostrzewa.com.pl.

 

INTERNET MODULE

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

 

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.

  PLATINUM BIO VG BURNER - FIRST VARIABLE GEOMETRY BURNER IN POLAND!

PLATINUM BIO VG BURNER - FIRST VARIABLE GEOMETRY BURNER IN POLAND!

Compatible with all fuel types (class: A1, A2, B) including an economy wood pellet with high sand content. 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.

PLATINUM BIO ECOMAX 860P TOUCH AUTOMATIC SYSTEM WITH COLOUR TOUCH CONTROL PANEL

PLATINUM BIO ECOMAX 860P TOUCH AUTOMATIC SYSTEM WITH COLOUR TOUCH CONTROL PANEL

An advanced device monitoring the combustion process in the boiler and the pellet burner.

The automatic system controls: fuel feeding from the storage tank, fuel feeder, pressure blower, igniter, CH pump, DHW pump, fuel level sensor, boiler/buffer tank pump, recirculation pump, linear actuator, buffer tank and three auxiliary mixing valves, central heating mixing valve and two auxiliary mixing valves - module C (optional).

Optional accessories: external temperature sensor, CH sensor, DHW sensor, return temperature sensor, colour ecoSTER TOUCH control panel with remote boiler control, programmable wireless 7-day thermostat, programmable wired 7-day thermostat, adjustable temperature sensor, EcoLAMBDA oxygen sensor, auxiliary extension module (C) and EcoNET internet module.

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.
