Safe, energy-saving and durable
Three-level safety intelligent antifreeze; three level antifreeze, room temperature control, wind pressure protection, low pressure combustion, flameout protection, low water pressure start, ultra-quiet technology
1. Ultra-quiet: the noise is lower than *7db, lower than ordinary refrigerators 
2. More safe and complete safety protection, extreme temperature protection, three-level intelligent antifreeze, etc.
3. More energy-saving, adjustable air distribution, more complete combustion, more energy-saving,
4 .More durable technology to reduce water pipe fouling, and solve the cleaning inside the pipe 5. Free temperature control, **-hour time-sharing heating, arbitrarily set segmented heating time
6. More worry-free flameout protection, can detect residual fire, residual fire, accident Faults such as flameout 7. More convenient touch control, sensitive and stable operation, strong durability

Precise temperature control, low pressure combustion, room temperature control, flameout protection, wind pressure protection, low water pressure start, ultra-quiet technology, three-level intelligent antifreeze, high and low water pressure protection, extreme temperature protection, enhanced combustion technology, perfect safety protection, make up Heat dissipation technology, non-extinguishing technology for switching of living water
