• High efficient energy saving: the heater exchanger and main burner adopt mostly advanced energy-saving and combustion technology to decrease gas consumption and burning noise.
• Low water-pressured startup: the water control linkage valve makes the heater start up under low water pressure and shortage areas and those living in high stairs.
• Manifold auto protection: for the sake of your safety. Ion flame inspection: to automatically shut down gas power under unexpected flameout.
• Over water pressure protection function: to automatically decrease pressure under excessive high water pressure.
• Controller design: both cold water and warm water can be properly controlled.
