G Series

Condensing gas heater

Higher efficiency and energy savings for better comfort thanks to the automatic modulation of the flame and ventilation.

Benefits

  • High thermal efficiency and respect of the new norms about the heating installation system. The choice of condensation for Gas Unit Heaters allows to obtain thermal efficiencies over 105% and consequently comparable with the best condensing boilers on the market. The remarkable advantage of Gas Unit Heaters is that the water distribution is not required, presenting a better global efficiency of the system.
  • Perfect modulation of the heating output. The energy needed is grant by the heaters in a uniform and adequate mode for any single part of the premises. Each heater is able to give its own heating output proportioned to heating demand. In this way the modulation will support an average efficiency of functioning much more higher than the nominal value of the system and a constant ambient temperature in any functioning condition.
  • CO and NOx emissions practically nil. The control of the total premix combustion permits also to avoid problems on the exhaust flue system.
  • G series heaters listed on the Energy Technology List (ETL), Entitling buyers to claim an Enhanced Capital Allowance.

Applications

  • Workshops and factories.
  • All premises where high comfort and high efficiency are required.
  • Commercial buildings and show rooms.
  • Sports halls and fitness centres.
