1. Boiler use and advantages 

Use of the boiler: 

 
The BENEKOV K14 hot water boiler is designed to heat small or low-energy houses, chalets and other 
buildings whose thermal loss does not exceed 15 kW. 
 
The BENEKOV K20 hot water boiler is designed to heat small or low-energy houses, chalets and other 
buildings whose thermal loss does not exceed 20 kW. 
 
The BENEKOV K25 hot water boiler is designed to heat small or low-energy houses, chalets and other 
buildings whose thermal loss does not exceed 25 kW. 
 
 
BENEKOV K14, K20 and K25 boilers are designed to burn wooden pellets.  
 

Boiler advantages: 

 

  the boilers meet the requirements of boiler class 5 and ECODESIGN 

  high efficiency of the boilers 

  minimal environmental impact 

  automatic boiler operation 

  patented burner solution with self-cleaning furnace 

  automatic boiler ignition and extinguishing 

  mechanical delivery of the fuel from external feeder to the furnace 

  simple, time-efficient use and maintenance 

  low operating costs 

  modern design
