КОС-ТВА Heating Boiler

The КОС-ТВА boiler is a modern, fully automated heating unit for burning solid fuel.

Fuel used:

• Main fuel — coal and fuel pellets, with a particle size of 5 - 20 mm;

• Alternative fuel — any solid fuel.

The boiler has an automatic combustion control system that maintains the flame without the need for relighting.

Fuel is automatically metered by the feed screw from the intermediate hopper according to the desired temperature.

The grate firebox burns the optimal amount of fuel needed to maintain the set parameters, allowing boiler efficiency to reach 78% with substantial fuel savings.

An additional emergency grate allows other fuels to be burned during power outages or interruptions to the main fuel supply.

Boiler maintenance is simple and consists of filling the intermediate hopper with fuel and removing ash from the ash pan.

A special mode supplies hot water in summer without activating space heating, minimising domestic hot-water  costs throughout the year.
