Boiler KP 08

Catalog number: HKXI0801R

Characteristic of KP 08 (8kW)

Boiler KP 08 with possible operation of continuous output from 2,4 kW to 8 kW.

This boiler is equipped with an automatic ignition and a semi-automatic heat exchanger cleaning. It is designed for installation in family houses with low energy consumption, where its operation is controlled by room sensors ot thermostat. The boiler is equipped with weather-compensation regulation. Additional remote control over GSM or internet is possible as well.

Operation and maintenance:

Automatic operation is managed by room sensors or thermostat, automatic fuel loading from the fuel bin. Permanent service is not needed, occasional service consists of controling the fuel level in the bin and checking the amount of ash in the ashtray.

In approximately monthly intervals semi-automatical cleaning of the heat exchanger and ash removal must be performed.


Boilers are intended for combustion of wooden pellets of a diameter of 6 mm or 8 mm.

Technical description:

Boilers consist of boiler body – a steel weldment with wall thickness of 3 – 6,3 mm; linear burner made from heat-resistant stainless steel, ceramic parts, boiler jacketing with thermal insulation, electronic control unit and fuel feeders. The boiler also includes components to ensure safe operation. Automatic control of operation provides control unit RKP together with room thermostats. The boiler output can be set in the range 30 – 100% of rated output and in this entire range the boiler achieves the same efficiency and emission limits. The boiler must have operating fuel tank, which can be placed freely around the boiler. All of Ponast boilers are made in Czech Republic.
