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.

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.

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.

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.
