China Gold Supplier Wholesale Price LPG/Natural Gas Instant Gas Water Heater with Water Flow Sensor
The built-in water flow sensor offers a sensitivity as high as 0.3L/min, accurately detecting minor flow variations to prevent false starts/stops and energy waste. The entire unit has passed national energy efficiency testing and explosion-proof certification. Equipped with a low-nitrogen burner and wind pressure resistance technology, it maintains stable combustion even in windy or fluctuating gas pressure environments. The control panel supports multi-language display and remote monitoring interfaces, facilitating integration into building management systems for centralized energy management and fault.

FAQ
Q1: Does it support automatic switching between natural gas and LPG?
A1: Yes. It features an intelligent fuel recognition chip that automatically adapts to gas pressure and combustion parameters upon connection, requiring no manual intervention.
Q2: What is the lifespan of the water flow sensor?
A2: It uses a contactless Hall magnetic induction design with a lifespan of up to 500,000 start-stop cycles. It does not restrict the water flow channel diameter and is resistant to scaling over long-term use.
Q3: What commercial venues is it suitable for?
A3: It is suitable for hotel rooms, school dormitories, employee apartments, gym showers, and other venues requiring centralized heating with frequent start-stop cycles.
Q4: Does it support custom外观 and LOGO?
A4: Yes. As a Gold Supplier, we offer OEM/ODM customization services for panel color, silk-screen LOGO, functional modules, etc.
Q5: How is quality ensured for bulk supply?
A5: Each batch undergoes full inspection on the production line, and third-party test reports are provided. Partner clients can conduct factory inspections and access a dedicated quality traceability system.
