Boiler Stalmark EKO VEGAS 14 kW
The EKO VEGAS boiler by STALMARK is an innovative and economical heating solution that meets all the requirements of the anti-smog resolution, Class 5 classification, and eco-design standards. Equipped with a horizontal boiler exchanger, the EKO VEGAS coal boiler facilitates device cleaning and utilizes natural chimney draft. Thanks to the 45-degree angle flue outlet, the chimney pipe can be installed vertically or horizontally. The compact dimensions of the boiler allow for installation even in small boiler rooms or basements (see the table with sizes).
Stalmark EKO VEGAS is a modern solid fuel recommended for central heating due to its high calorific value and efficiency. Produced from high-quality coal with low sulfur content is ground to grains ranging from 5 to 25 mm and sold in convenient 20-25 kg packages. Coal boilers are environmentally friendly (achieving combustion efficiency from 89.7% to 90.5%, depending on the boiler model) and highly efficient, enabling savings through efficient coal dosing in small portions.
Ekoenergia Feeder
The most popular ecoalloy burner in Poland, made of gray cast iron and equipped with a ductile iron auger, is characterized by increased corrosion resistance. This is particularly important when burning fuels with varying moisture levels.
TECH ST-755 zPID Control
Boiler is equipped with the convenient ST-755 zPID controller by TECH, which manages the boiler's operation and consumes only 11W of power. It operates in a PID algorithm with flue gas temperature sensor (intelligent fuzzy logic algorithm) allowing for savings of up to 25%. The boiler controller allows for the operation of four independent heating circuits (4 pumps) plus 1 mixing valve, auger feeder, and forced draught. It supports four foreign languages by default:
- Polish
- English
- German
- Czech
