Venibe solid fuel boiler 20 kW
Description:
Venibe hot water boilers are designed for heating residential buildings, administrative buildings, and industrial buildings. They require no constant supervision during operation.
The boilers use wood, coal, various sawdust briquettes, peat, and mixtures thereof as fuel. Humidity is no more than 25%. The boilers feature primary and secondary air supply, a ceramic catalyst, good thermal insulation, and a modern heat exchanger design, resulting in high efficiency, up to 79% for various fuels.
The boiler bodies are welded from 3 and 6 mm sheet steel and have channels in which the heat carrier (water or a special liquid) circulates.
An automatic thermostat maintains the required coolant temperature. The boiler design allows for multiple boilers to be connected in parallel. The boilers are equipped with high-temperature catalysts, ensuring more complete combustion of the fuel.
