- Summer Mode: Supplies hot water only without activating the heating circuit.
- Winter Mode: Activates both room heating and domestic hot water output simultaneously.
- Timer Function: Supports scheduled heating turn-on and turn-off for energy efficiency.
- Fault Self-Diagnosis: Detects errors and displays corresponding error codes for quick troubleshooting.
- Easy Disassembly Design: Simplifies daily cleaning and maintenance work.
Flue Wind Pressure Protection: Continuously monitors exhaust pressure during boiler operation. If the flue is blocked, bent improperly, or obstructed by debris, the protection system triggers gas cutoff and shuts down the burner. This prevents waste gas backflow into living spaces and avoids poisoning risk, adapting to complex flue installation layouts in old renovation houses.
Our combi boiler supports both natural gas and an optional LPG conversion kit for flexible fuel switching. Buyers can replace gas nozzles and adjust combustion parameters to switch fuel type, making this boiler suitable for regions without a natural gas pipeline where bottled liquefied petroleum gas is widely used.
A gas pressure sensor continuously monitors inlet gas pressure. When gas pressure goes beyond the normal working range — either too high or too low — the boiler triggers an alarm and cuts gas supply, avoiding incomplete combustion under low gas pressure or flame lifting caused by excessive gas pressure.
The wide voltage adaptation design allows stable operation under fluctuating grid voltage. Voltage surges and sudden drops will not lead to unexpected shutdown or main PCB burnout, improving reliability in rural and remote areas with unstable power supply.
A1: It protects the pump when all radiator valves are fully closed.
A2: A magnetic filter on the return line is highly recommended.
A3: Yes, use a suitable concentration of propylene glycol for cold climates.
A4: Slightly — the concentration must be adjusted strictly.
A5: Yes, choose a heating system corrosion inhibitor compatible with copper and steel.
A6: A solid brick or concrete wall is required; the wall bracket bears the full boiler weight.
