- With control circuit boards, control centers for high-intelligent equipment operation and safety protection.
- With multi- stage intelligent antifreeze, multi-stage combustion, the temperature is less than 8 degrees celsius
to start automatically, the pump after the cycle in the burning to stop working, the pump.
- Ultra-low pressure start, hot water hot start, short time cycle control, circulation pump delay control.
- With LED all- round electronic display.
- The temperature gradient control function and the three anti freezing control are unique, and the safety protection
is up to 28. The design life of the whole machine is more than 15 years.
- Low noise design, using cast aluminum fan, intelligent control gas proportional valve, with special combustion
and water system, running noise is less than 42 dicebel.
- The invention patent high-frequency electronic anti scaling device and the original windbreak and sand structure
design are committed to manufacturing gas wall hanging stove products suitable for our conditions.
- 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℃)
- Modulation: boiler output changes automatically to keep the set heating and DHW temperature constant, with great
optimization of gas consumption.
- Integrated pump, expansion tank, heating safety valve,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.
- Neat design, gas saving, high efficiency, environmental protected. Adopt advanced technology, high quality components,
high efficiency combustion.
