EKO-TECH boilers with an automatic fuel supply system are meant to be used in central heating installations as well as for warm utility water preparation in housing such as detached houses, stores, garages and utility buildings.

DUO ZP means an automatic retort boiler with full function of the classical (normal) boiler. The boiler may have an additional cast iron grate and an extra large combustion chamber which allows burning of all solid fuels. If necessary, the boiler can burn coal or wood, for a long, not limited time.

The KRS Tech DUO 18 kW boiler has the 5 emission class, so it has no additional grate and therefore no alternative fuels to burn.

Advantages of the Tech DUO boilers:

- high efficiency,
- automatic functioning,
- quick and easy maintenance,
- economical fuel burning,
- smoke free and ecological burning,
- possibility to steer CH and DHW pumps,
- possibility to install a warm water exchanger.
