 Features and benefits

  • High-efficiency floor standing boiler up to 99% GCV – higher than average energy savings
  • Extremely compact – particularly suitable for retrofit applications
  • Low Class 6 NOx emission levels from 29mg/kWh (0% O2 dry) – low pollutant emissions meeting all environmental legislation
  • Premix gas burner and one-piece cast aluminium heat exchanger – clean, trouble-free operation
  • Cleanable heat exchanger – as with all Quinta Ace models – dry side can be examined and descaled. Cleaning tool and gaskets available
  • Built-in advanced boiler control and calorifier control fully modulating 18–100% (5:1), 0–10V operation, on/off (volt free enable) – built-in flexibility for easy installation
  • Cascade/modular packages for up to four boilers – effective space-saving solution for greater design flexibility
  • Ultra-quiet operation, less than 45 dBA – improved comfort
  • For use with natural gas and LPG (90kW requires a conversion kit) – flexible solution to energy-saving heating
  • Easy operation and maintenance - Digital diagnostic display and remote signalling options
