The PK350 Everclean pellet boiler is high-efficiency 3-pass water boiler for wood pellet burner. PK250 boiler is designed to work together with PV 350 pellet burner.

The automatic cleaning mechanisms guarantee long maintenance intervals and keep the efficiency high. Third pass heat exchanger tubes and second pass tube are cleaned pneumatically. The fly ash is moved to back of the boiler. Automatic ash removal of the boiler consists the scrape of the bottom of the furnace. On the bottom of the boiler lies ash auger that transports the ash further. The ash can be collected in a suitable container behind the boiler or outside the boiler house.

Construction of the boiler door allows very easy accessibility to the boiler. Because of the compact size of the boiler, it is possible to install it into sea containers or other similar space-saving buildings.

Base FeaturesSpecificationDocumentation

  • High efficiency

    PK250-PK1000 pellet boilers have efficiency up to 94% when converting pellets into heat.

  • Automatic cleaning
