Optional Color Gas Water Heater Providing Heating Efficiency ≥85 Percent Energy Consumption for Industrial and Residential

Product Description

Bottled gas is often the most practical fuel in homes beyond the reach of a municipal network, but every unnecessary burner cycle raises the cost of the next cylinder. This 6L flue type instant gas water heater is designed for households that want useful shower output without heating a stored tank or keeping water warm between draws. Opening the tap activates the water-gas interlock valve, the battery-powered pulse system lights the burner, and hot water begins to arrive within seconds. Its compact output is matched to single-point household use, making it a sensible choice for a shower, wash basin, or kitchen tap rather than an oversized system that consumes more fuel than the application requires. A winter-summer selector reduces unnecessary heat input when incoming water is already warm, while the adjustable controls let users balance gas and water according to local conditions. Inside, an oxygen-free copper heat exchanger transfers heat efficiently and resists corrosion, while the harmonica-shaped three-section burner spreads flame across the heating surface for more even operation.

Specifications

The wall-mounted body measures 440 by 300 by 120 millimetres, allowing it to fit where a deeper appliance would obstruct a narrow kitchen or service balcony. Rated heat input is 12 kilowatts, and the unit supplies approximately 6 litres per minute at a 25-degree Celsius temperature rise. Thermal efficiency reaches at least 84 percent through the copper heat exchanger, which can be specified in different weight grades to suit the required market position. Water temperature is adjustable from 30 to 55 degrees Celsius, while heating begins within 15 seconds and settles within the same period under suitable inlet conditions. The operating water-pressure range is 0.02 to 0.8 megapascals. LPG versions are configured for 2800 pascals and natural-gas versions for 2000 pascals. The ignition circuit uses a DC 3V battery supply, and the water inlet, outlet, and fuel connection all use G1/2-inch threads. Exhaust leaves through a 90-millimetre natural-draft chimney.

Technical Parameters

Installation Scenarios & Installation Precautions

This configuration suits homes supplied by LPG cylinders, semi-open kitchens, ventilated service balconies, covered utility corridors, and small residential annexes with one main hot-water outlet. Installation must be completed outside a sealed bathroom and away from bedrooms, stairwells, or storage rooms that lack a permanent combustion-air route. The 90-millimetre smoke pipe must lead outdoors and should rise as directly as possible so natural draft is not weakened by unnecessary horizontal bends. An open window, fixed louvre, or door grille must provide replacement air whenever the heater operates. Confirm that the mounting surface supports the filled appliance, leave at least 200 millimetres above the housing and 150 millimetres at both sides for servicing, and test every fuel joint with soap solution before commissioning. The LPG cylinder and regulator should be placed according to local gas codes, normally outside the occupied room, and the battery polarity must be checked before the first ignition attempt.

Features & Value Delivered to Global Buyers

The commercial case rests less on adding decorative functions than on controlling lifetime fuel and service costs. Low-pressure startup, dual ignition pins, flame-failure protection, anti-dry burning protection, overheat control, over-pressure protection, and the 20-minute timer address the failures that matter in daily use. The winter-summer selector gives retailers a clear gas-saving benefit to explain at the point of sale. Buyers can choose white-coated, stainless-steel, or glass panels, specify housing colours and silk-screen branding, and order LPG or natural-gas calibration for the destination market. OEM orders begin at 100 pieces per model, with samples available according to configuration and normal production completed after deposit confirmation. A one-year warranty and complimentary service parts support distributors after delivery.

Safety Boundaries & Long-Term Use Reminders

This open-flue heater is not intended for sealed bathrooms, sleeping rooms, buildings without permanent ventilation, or outdoor walls exposed directly to rain. It should not serve continuous industrial demand or water systems above 0.8 megapascals unless pressure is reduced upstream. Keep combustible materials away from the housing, do not cover the top opening, and close the fuel supply immediately if an unusual odour or delayed ignition occurs. The flame should remain predominantly blue; persistent yellow combustion requires professional inspection. Replace the DC 3V batteries annually, rinse the inlet filter every three months where sediment is common, and inspect the chimney terminal for leaves, nests, or corrosion before each high-use season.
