Features

HIGH EFFICIENCY AT A GREAT PRICE

Our new boiler is an efficient and eco-friendly solution designed for large apartment buildings and industrial facilities. The boiler heat exchanger features a ceramic chamber for high fuel economy, lower emission and higher efficiency and flue gas vortex generators retaining energy inside the boiler.

 

MANY YEARS OF FAILURE-FREE OPERATION

Highest quality materials and components by renown manufacturers guarantee the highest reliability of our boilers. Regular maintenance and annual inspections guarantee failure-free operation for over a dozen years.

 

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 (OMS System). The number of visits to the boiler room can be kept to a minimum.

 

SELF-CLEANING BURNER

Innovative rotary PLATINUM BIO SPIN burner guarantees maintenance-free combustion of class A1, A2 and B wood pellets. The technology used allows to purchase pellet up to 50% cheaper than available for owners of other boilers (usually more expensive class A1 pellets).

 

INTERNET MODULE

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

 

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.

 

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.

OMS PRO (OPERATING MONITORING SYSTEM)

OMS PRO (OPERATING MONITORING SYSTEM)

A remote monitoring and operating system developed by KOSTRZEWA for large pellet boiler rooms. The control system of a boiler and its function often does not meet all the requirements of the owner or boiler room operator. We have developed OMS PRO to provide additional functions: remote monitoring of the boiler room parameters, boiler cascade system monitoring, auxiliary heat source control, fuel storage and feeding system control, emergency and reserve conditions monitoring and many other functions. OMS PRO also allows real-time monitoring by our service department with remote access and technical support.

PLATINUM SPIN BIO BURNER

PLATINUM SPIN BIO BURNER

An innovative burner with a rotating combustion chamber for granulated biomass fuels with ash content up to 2% (pellet class A1, A2, B); patented at the Patent Office of the Republic of Poland. 2nd generation Fuzzy Logic controller and two-section menu for reduced fuel consumption by up to 20% and reduced component wear compared to other available burners (reduced number of burner start-ups significantly reduces the amount of energy used). Burner cleaning has never been this easy - mechanical cleaning of the combustion chamber through the rotation of Platinum Bio SPIN’s grate. The rotation frequency is programmed to remove excessive ash depending on the fuel used to reduce burner shutdowns interval from 3 days to about 2 weeks (depending on the ash content of the fuel).

  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 STORAGE HOPPERS

PELLET STORAGE HOPPERS

Galvanized and machine manufactured pellet storage hoppers are used as intermediate stores. The storage hoppers can be refilled manually or automatically from another store using Pellets Vacuum system. Available storage hopper capacities allow to position the boiler anywhere in the boiler room and extend the boiler operation time without manual refills. The boilers include a 295 l storage hopper as standard (up to 192 kg of pellet at 650 kg/m3 bulk density). Optional storage hoppers up to 1460 l capacity (approx. 1 tonne of pellet) are available.
