3 Burner LPG Gas Water Heater Designed with Copper Heat Exchange Material Providing Heating Performance and Energy Operation

Product Description

In warm regions, incoming water may already be comfortable for much of the year, so applying full burner output wastes bottled gas and can make a shower harder to regulate. This 6L flue type instant gas water heater combines seasonal fuel adjustment with cold-hot water switching to give tropical and subtropical households better control over modest temperature lifts. The platform uses a 12-kilowatt harmonica-shaped burner at maximum demand, but the user can reduce combustion when mains or tank water arrives warm. Water movement triggers the interlock valve and DC 3V pulse ignition, so no fuel is consumed between draws. An oxygen-free copper heat exchanger transfers heat to approximately 6 litres per minute at a 25-degree Celsius reference rise, while the practical control range extends from 30 to 55 degrees. Designed for one outlet, the unit suits homes where LPG cylinder economy matters and a large storage system would be unnecessary. Its compact body also avoids occupying floor space in small service zones.

Specifications

The appliance measures 440 by 300 by 120 millimetres and mounts on a vertical wall. Rated heat input is 12 kilowatts and thermal efficiency reaches at least 84 percent through the copper core. Nominal flow is 6 litres per minute at the specified rise, with heating and stabilisation each achieved within 15 seconds under appropriate conditions. The control range is 30 to 55 degrees Celsius, while accepted water pressure spans 0.02 to 0.8 megapascals. LPG models use 2800-pascal supply; natural-gas versions are separately calibrated for 2000 pascals. Automatic pulse ignition runs on DC 3V and uses two pins. Three G1/2-inch ports handle cold water, hot water, and fuel, and a 90-millimetre natural-draft chimney removes combustion products. Optional LED or LCD indication can support clearer adjustment where specified.

Technical Parameters

Installation Scenarios & Installation Precautions

This model fits tropical island homes, ventilated wet kitchens, semi-open wash areas, covered rural verandas, and small coastal guesthouses with one shower or basin in use. Mount it outside the bathroom and provide a continuous air source through an openable window or fixed louvre. The 90-millimetre smoke pipe must terminate outdoors and should remain mainly vertical to preserve draft in humid, low-wind conditions. Avoid enclosed courtyards where exhaust can recirculate and protect the unit from direct monsoon rain. Check wall strength, maintain 200 millimetres above and 150 millimetres at the sides, and keep LPG cylinders outdoors with a correct regulator. Confirm fuel calibration, test joints with soap solution, and commission the summer setting at a moderate temperature before explaining the cold-hot controls to users.

Features & Value Delivered to Global Buyers

The practical difference from a fixed-output model is the ability to reduce unnecessary seasonal combustion while retaining full 12-kilowatt capacity when cooler inlet water arrives. Cold-hot conversion, winter-summer selection, low-pressure activation, dual ignition pins, flame-failure shutdown, anti-dry operation, excess-pressure protection, overheat control, and the 20-minute limiter form a coherent household package. OEM programs may adapt control labels for local language and climate, choose panel material and colour, and add branded printing or temperature display. Wholesale orders begin at 100 pieces per model, with sample review, scheduled production after deposit, free service components, and one-year warranty support.

Safety Boundaries & Long-Term Use Reminders

Seasonal controls do not provide automatic thermostatic regulation, and users must adjust the appliance when inlet conditions change. It is not suitable for sealed bathrooms, bedrooms, multiple simultaneous outlets, or unprotected exterior mounting. Start at a moderate setting and test water before showering, especially after changing seasonal mode. Shut the LPG valve if odour is detected and never place cylinders inside the occupied room. Replace batteries yearly, clean the inlet filter, inspect the chimney after storms, and schedule burner and safety-device checks before each main visitor or bathing season.
