With large LED display and high intelligent control system wall hung gas boiler high efficiency combustion
- Air draught model. Open chamber, especially design for house type with collective flue.
- Neat design, gas saving, high efficiency, environmental protected. Adopt advanced technology, high quality components, high efficiency combustion.
- Various capacity available. Input capacity(20kw,24kw,28kw,32kw) can match with different house type.
- Can be connected with room thermostat or remote controller which providing more function options.
- Various structure available,suitable for different using condition.
- Integrated pump, expansion tank, heating safety,manometer, automatic air exhaust device.
- Frost protection: Burner and pump will be switch on automatically by danger of freezing. It is allowed to use antifreeze liquid instead of water in the heating system.
- Steady ignition and work by low inlet gas pressure from 3mbar, full output by inlet gas pressure from 13mbar and higher.
- Protected service menu for internal functions and working parameters adjusting.
- Indication of temperatures, working modes, current burner power and error codes on the color multifunctional LED display.
- Modulation: boiler output changes automatically to keep the set heating and DHW temperature constant, with great optimization of gas consumption.
- Fan burner with full gas- air premix provides gas combustion with close to ideal conditions-so the condensation process begin earlier and by higher return line temperature(about 57℃)
