High efficiency and energy saving

With SPOILER-FLUE high-efficiency turbulent heat exchange technology, the thermal efficiency reaches up to 87%. The thickened polyurethane insulation layer reduces heat loss, and the specially designed flue baffle decreases flue heat loss by 60% during standby mode.

Safe and reliable

Dual-stage ignition with automatic gas valve control; four layers of safety protection including thermostat, high-temperature limit, overheat protection, and TP valve ensure operating safety. The pressure-bearing capacity reaches up to 1.1 MPa, allowing stable operation under fluctuating water supply pressures.

Silent operation

Atmospheric combustion design eliminates the need for a combustion fan, resulting in low operating noise.

Easy to installation

Suitable for both indoor and outdoor installation, with an optional forced-exhaust fan available.
