Thermal Efficiency 85 Percent Flue Gas Water Heater Rated Power 20000 W Suitable

Thermal Efficiency 85 Percent Flue Gas Water Heater Rated Power 20000 W Suitable Installation Location Kitchen Balcony

Product Description

A strong crosswind can alter pressure at a chimney terminal and disrupt the natural movement of exhaust. This 10L flue type instant gas water heater is positioned for exposed service areas through the combination of an anti-wind flow-back feature, flame-failure shutdown, and a correctly specified 90-millimetre chimney route. The device adds resilience but does not excuse poor terminal placement. During normal operation, water movement activates DC 3V pulse ignition, two electrodes light the harmonica-shaped triple burner, and 20 kilowatts of input pass through the copper exchanger. The unit supplies approximately 10 litres per minute at a 25-degree Celsius rise and allows adjustment from 35 to 80 degrees Celsius for one household outlet. Because it heats only on demand, there is no tank to recover after use. For hillside, coastal, or open-balcony projects, the real benefit is a coordinated response to wind risk: thoughtful siting, stable combustion, and immediate gas shutdown if the flame is lost.

Specifications

The casing measures 590 by 340 by 180 millimetres and weighs around 8 kilograms net. Packed size is 670 by 405 by 230 millimetres with a gross weight near 9 kilograms. Rated input is 20 kilowatts, thermal efficiency is at least 85 percent, and nominal delivery is 10 litres per minute at the stated rise. Operating pressure spans 0.02 to 0.8 megapascals, with startup near 0.015 megapascals under appropriate flow. LPG models use 2800 pascals and natural-gas models 2000 pascals. DC 3V batteries drive dual-pin ignition. Heating begins and settles within 15 seconds when draft and supplies are correct, with outlet overshoot specified within 2 degrees Celsius. G1/2-inch threads connect water and gas, while natural exhaust passes through a 90-millimetre collar.

Technical Parameters

Installation Scenarios & Installation Precautions

Suitable sites include hillside homes, covered coastal corridors, exposed service balconies, mountain guesthouses, and rural kitchens facing seasonal winds. Survey prevailing wind before choosing the terminal. Avoid locations directly beneath eaves, within narrow courtyards, behind parapets, or opposite walls that create pressure pockets. The chimney must terminate outdoors, rise predominantly upward, and use a locally approved cap. Permanent replacement air through an openable window or fixed grille remains essential. Never install in a sealed bathroom, bedroom, staircase, or enclosed space. Confirm wall load, leave 200 millimetres above and 150 millimetres at each side, test joints with soap solution, and observe flame behaviour during realistic windy conditions at commissioning.

Features & Value Delivered to Global Buyers

The wind-oriented package combines backflow resistance, fast flame-loss gas closure, and a standard chimney interface that accepts regionally suitable terminals. Low-pressure activation, dual ignition, water-gas interlock, dry-burn prevention, overheat and pressure protection, seasonal control, and a 20-minute limiter complete the platform. Buyers may specify panel material, colour, display, warning labels, branding, and carton graphics. MOQ is 100 pieces per model, samples allow regional draft testing, and normal production starts after approval and deposit. One-year warranty support includes free routine replacement parts.

Safety Boundaries & Long-Term Use Reminders

The backflow device cannot make a chronically reversing flue safe and does not create sealed combustion. This heater is unsuitable where correct terminal design still cannot maintain draft. Stop operation after repeated flame loss, lifting flame, or yellow combustion. Never add improvised mesh or caps that may collect soot and debris. Inspect the chimney after storms, secure loosened joints, clear nests and leaves, replace batteries annually, and ask a qualified technician to investigate recurring shutdown. Direct rain exposure and operation without permanent combustion air remain prohibited.
