3 Burner Number Flue Gas Water Heater Incorporating Copper Heat Exchange Material and All Color Will Be for Performance

Product Description

A water heater that requires proprietary fittings can remain out of service for weeks when a small part is unavailable locally. This 6L flue type instant gas water heater is built around familiar installation interfaces: a 90-millimetre chimney outlet, G1/2-inch water and fuel threads, mechanical adjustment, and DC 3V battery ignition. These standard elements help regional installers source compatible pipework and complete routine maintenance without depending on a closed accessory system. Behind the practical connections, a 12-kilowatt harmonica-shaped burner directs flame across an oxygen-free copper heat exchanger and produces approximately 6 litres per minute at a 25-degree Celsius rise. Heating occurs only while water flows, so there is no storage cylinder to keep warm or replace after corrosion. The 30-to-55-degree adjustable range fits ordinary washing and shower requirements for one outlet. For distributors serving distant towns, islands, or inland regions, compatibility with common fittings becomes a measurable ownership benefit rather than a minor specification.

Specifications

The wall-mounted casing is 440 millimetres high, 300 millimetres wide, and 120 millimetres deep. Its rated thermal input is 12 kilowatts and minimum documented efficiency is 84 percent. At the reference temperature rise, hot-water output is approximately 6 litres per minute. The heater operates across 0.02 to 0.8 megapascals of water pressure and adjusts between 30 and 55 degrees Celsius. LPG calibration uses 2800 pascals, while the separately prepared natural-gas model uses 2000 pascals. Two ignition pins receive pulses from a DC 3V battery source. The three-section burner and copper heating core begin raising water temperature within 15 seconds under normal conditions. Water inlet, outlet, and gas connection are all G1/2 inch, and the natural-draft collar accepts a 90-millimetre smoke pipe selected to meet local material and code requirements.

Technical Parameters

Installation Scenarios & Installation Precautions

The standard-interface design suits small-town dealerships, rural renovation projects, island service networks, staff housing, and guest properties where replacement hardware must come from local plumbing suppliers. Compatibility does not remove the need for qualified installation. The smoke pipe must lead outdoors, rise as directly as possible, and include an approved terminal suitable for the building and climate. Provide permanent replacement air and never mount the heater inside a sealed bathroom, bedroom, stair enclosure, or unventilated store. Check the wall, leave 200 millimetres above and 150 millimetres at both sides, and prevent long horizontal chimney runs. G1/2-inch thread designation alone does not guarantee every local fitting has the correct sealing form, so the installer must use approved adapters and sealants. Leak-test the fuel circuit and verify the ordered LPG or natural-gas pressure before ignition.

Features & Value Delivered to Global Buyers

The commercial advantage rests on repair access, installation familiarity, and lower spare-accessory risk. Standard connections combine with low-pressure startup, battery pulse ignition, dual electrodes, water-gas interlock, seasonal control, flame-loss protection, dry-burn prevention, overheat shutdown, pressure protection, and a 20-minute limiter. Buyers can still customise panel finish, colour, printed identity, and display type without changing the core service interfaces. MOQ begins at 100 pieces per model, sample units can be checked against regional fittings before a volume order, and production follows approved specifications and deposit. A one-year warranty and free service parts give distributors a practical basis for local support.

Safety Boundaries & Long-Term Use Reminders

Locally available pipework must still be rated for temperature, fuel, and flue duty; improvised plastic exhaust duct or unapproved gas hose is unacceptable. The unit cannot operate safely without outdoor exhaust and permanent room ventilation. It is not suitable for direct rain, sleeping rooms, or pressure above 0.8 megapascals without reduction. Inspect threaded joints after installation and again after the first heating cycles. Replace batteries annually, clean the water inlet screen, check the burner flame, and examine the chimney for loose joints, corrosion, or blockage. Any recurring fuel odour or ignition delay requires shutdown and qualified service.
