A gas-saving heating solution engineered for reliable domestic hot water and central heating performance.

• 1.Modular internal layout helps technicians quickly replace spare parts.
• 2.Adjustable water flow rate meets different domestic hot water demands.
• 3.Integrated bypass valve protects the system under blocked pipeline conditions.
• 4.Hot water priority mode gives priority to bath hot water demand.
• 5.Smooth temperature transition avoids sudden hot water temperature surges.

This combi boiler supports low water pressure startup, making it suitable for high-rise buildings and communities with unstable tap water pressure. Even under low inlet water pressure conditions, the flow sensor can detect the water signal normally and activate hot water heating. Homeowners living on high floors no longer need to worry about weak water flow and failure to start the hot water function.

The built-in circulating pump drives heating water circulating inside radiators or underfloor heating pipes. The pump speed can be adjusted to match different pipeline resistance for small or large heating systems. Anti-blocking protection activates regular short rotation during long idle periods, preventing impeller rust and seizure so the pump can restart smoothly after months of standby.

Pump overheat protection continuously monitors pump winding temperature. If pump overload leads to a rapid temperature rise, the boiler reduces load or shuts down the pump automatically to avoid coil burnout and pump failure, which would interrupt whole-house heating.

Vibration isolation pads are fitted between the pump assembly and boiler frame to reduce vibration transfer to the wall and connected pipelines, lowering resonance noise and protecting pipe joints from vibration fatigue cracking over long-term operation.
