Ultra-low-temperature composite petrol boilers with a stainless heat exchanger for hot-gas condensation, with an efficiency of 103% and an output range from 20.2 to 53.7 KW

  • Triple heating surface for long service life.
  • Economical through low temperature of the water in the boiler, which shuts down completely when no heat is required.
  • Low-temperature petrol / gas boiler made from high-quality cast iron, with a minimum limit of 40οC.
  • Composite petrol boilers, with a double heating surface of cast iron and steel and a stainless heat exchanger for hot-gas condensation, for ultra-low feedwater temperatures with no minimum limit (Vitola – Biferral heating surface).
  • Maximum economy in consumption due to hot-gas condensation and reduced heat loss to the chimney (hot gases exit at a temperature of 10ºC above that of the feedwater), which saves at least 20% of fuel.
  • Standard efficiency: 103%.
  • The Biferral composite surface and the stainless heat exchanger ensure high efficiency and a long service life.
  • Easy cleaning of heating surfaces. Smooth and continuous hot-gas flues.
  • Low pollutant-emissions (< 80 mg/KWh NOx,< 10 mg/KWh CO) and a blue flame thanks to the Vitoflame 300 petrol burner that perfectly matches the combustion-chamber geometry.
  • Economical and environmentally friendly through operating at ultra-low temperatures depending on outside temperatures and shutting down completely when no heat is required.
  • Simple installation and commissioning. Vitoflame petrol burners are factory-tested under operating conditions and factory-preset to the rated boiler output.
  • Very small chimney cross-sections and capability of operation, even when supplied with a plastic chimney, due to the low temperature of hot-gas emissions.
