Features

IMPROVING ON THE ICONIC MINI BIO
Designed for heating buildings without boiler room or with small boiler room. Reduced overall dimensions with a storage hopper installed on the heat exchanger - a solution used for the first time by Kostrzewa in 2009 in our flagship product Mini Bio boiler and well-received by our clients. A new version with improved comfort, cleanliness and a guaranteed energy-efficiency.

 

SIMPLE AND CONVENIENT
The OMS (Operating and Monitoring System) monitors fuel level and ash content. User is informed in advance that the fuel storage must be refilled or the ash pan requires cleaning.

 

LOW FUEL USE
Reduced fuel consumption with Mini Bio. A unique design and advanced ceramic inserts for over 90% efficiency.

 

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.

 

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 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 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.

GREAT POSSIBILITIES
  PLATINUM BIO BURNER

PLATINUM BIO BURNER

compact, silent and energy-efficient.

 

FEATURES:
automatic burner start-up, automatic burner modulation with 2nd Generation Fuzzy Logic, flame control with a photocell, low thermal inertia during start-up and shutdown, low power input, burner temperature control for highest safety, three-stage start-up to prevent gas explosions, AUTOSTART after power loss - the current settings are stored, separate primary and secondary air ducts for reduced CO emission (emission levels similar to gas and oil burners), automatic cleaning function - automatic slag removal from the grate (not available in the gravity fed models), oats - burner design allows use of oats as a fuel, ceramic insert - reduced emission and higher efficiency.

  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-S – SIMPLE CONTROL SYSTEM

PLATINUM BIO ECOMAX 860P-S – SIMPLE CONTROL SYSTEM

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

 

SYSTEM CONTROLS:
fuel feeding from the storage tank, fuel feeder, pressure blower, igniter, CH pump, DHW pump, fuel level sensor, boiler/buffer tank pump, heating circuit mixing valve - module B (optional), recirculation pump - module B (optional), buffer tank - module B (optional), two auxiliary mixing valves - module B (optional) and two auxiliary mixing valves - module C (optional).

 

OPTIONAL ACCESSORIES:
external temperature sensor, CH sensor, DHW 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 (B, C) and EcoNET internet module.

WYPOSAŻENIE OPCJONALNE:
czujnik temperatury zewnętrznej, czujnik c.o., czujnik c.w.u., kolorowy panel pokojowy ecoSTER TOUCH z funkcją zdalnego sterowania kotła, termostat pokojowy programowalny tygodniowy bezprzewodowy, termostat pokojowy programowalny tygodniowy przewodowy, czujnik temperatury z regulacją, zestaw sondy lambda EcoLAMBDA, dodatkowy moduł rozszerzeniowy (B,C), moduł internetowy EcoNET.

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.
