Description
Ekogroszek Boiler STALMARK EKO VEGAS
The EKO VEGAS boiler from STALMARK is an innovative and economical heating solution that meets all anti-smog resolution requirements, Class 5 classification and ecodesign standards. Equipped with a horizontal boiler heat exchanger, the EKO VEGAS ekogroszek boiler facilitates device cleaning and utilization of natural chimney draft. Thanks to the chimney outlet at a 45-degree angle, it is possible to install the chimney pipe vertically or horizontally. The compact dimensions of the boiler allow its installation even in small boiler rooms or basements (see the table with dimensions).
Ekogroszek is a modern solid fuel, recommended for central heating due to its high calorific value and efficiency. Produced from high-grade coal with low sulfur content, EKO VEGAS ekogroszek is ground into grains sized from 5 to 25 mm and sold in convenient packages weighing 20-25 kg. Ekogroszek boilers are environmentally friendly (achieving combustion efficiency from 89.7% to 90.5%, depending on the boiler model) and highly efficient, enabling savings through effective coal dosing in small portions.
Ekoenergia Feeder
The most popular ekogroszek burner in Poland, made from gray cast iron and equipped with a screw made of spheroidal cast iron, is characterized by increased corrosion resistance. This is particularly important when burning fuels with different moisture levels.


Control TECH ST-755 zPID
The Eko Vegas boiler is equipped with a convenient ST-755 zPID controller from TECH that manages the boiler operation, which draws only 11W for its power supply. It operates in a PID algorithm with a flue gas temperature sensor (intelligent fuzzy logic algorithm - Fuzzy Logic) which allows for savings of around 25%. The boiler controller allows you to operate four independent heating circuits (4 pumps) plus 1 mixing valve, auger feeder and air supply. Standard support for four foreign languages:
- Polish
- English
- German
- Czech
