Multi-dimensional noise reduction mute structure

The source of noise elimination is not noisy, so quiet that you doubt your ears.

Optimized design according to the principle of combustion science, "structural noise reduction" and "root cause noise control" technology direction to block the spread of noise, quiet as low as 37.8dB.

Enclosed stable combustion chamber technology

Ten-level wind also stable combustion, constant hot water source.

The special closed stable combustion chamber prevents the backflow of gale, the lower blower increases oxygen, isolates the external interference, the fan can match the speed with the external wind pressure intelligently, the fire does not flutter, and the water temperature is more stable.

Constant water temperature anti-wave program

The water temperature is constant at all times, and it is easy to feel comfortable in the bath.

Matching the fine water and air dual-regulation control, the water temperature control in the earth 0.5 ℃, so that the skin can not feel the water temperature change, to realize the real zero sense of comfort.

Micro-flame combustion technology

Wen fire micro-warm baby wash, summer bath without scalding.

Intelligent five-section combustion, summer bathing is not hot, the lowest temperature rise as low as 4K (10L water), the real precision control temperature rise; winter fire full open, enjoy the surging hot water.

AI four seasons free adjustable intelligent temperature sensing

Four seasons without adjusting the temperature, hot and cold changes in the temperature remains unchanged.

Real-time sensing of environmental temperature changes, intelligent adjustment of the water temperature, without the need to manually adjust the complexity of the four seasons of warm bath with a key.


Coil-less armored water tank

Thousands of hammered oxygen-free copper, the real material can be seen.

Oxygen-free copper water tank material is thick, uniform heat, water absorbs more heat, water temperature is constant, no coil structure, completely solve the corrosion of the side pipe, no harmful substances, clean water.

Dual anti-freeze protection technology

The internal and external protection is always on standby to cope with bad weather.

Intelligent sensing of the outdoor air temperature, double-pronged effective protection against cold weather on the internal water circuit. In the northern region, even in windy and snowy weather, it can be burned freely and steadily.

Intelligent three-stage water volume change

Energy-saving quick heating without exhaust gas, enough hot water without waste.

Different water scenarios, different heat loads, intelligent switching of water output, energy-saving three-stage variable rise, small use is not wasted, large use of hot water enough to save money and more worry.
