Timer 20Min Inbuilt Flue Gas Water Heater with Battery Operated Ignition Method

Timer 20Min Inbuilt Flue Gas Water Heater with Battery Operated Ignition Method Rated Gas Pressure LPG 2800pa NG 2000pa Compact

Product Description

Residents on upper floors of tall buildings, in older neighbourhoods with tired mains supply, or in villages with gravity-fed water systems all share a frustrating problem: water pressure that simply isn't strong enough to trigger conventional water heaters. Our 10L Flue Type Instant Gas Water Heater solves this frustration through a water-control linkage valve engineered to detect and respond to pressures as low as 0.015 megapascals, well below the 0.02-to-0.03 megapascal threshold that leaves most competitors sitting silently. The moment a tap opens and even a trickle begins flowing, the valve mechanically opens the gas pathway, the dual pulse ignition pins strike, and the harmonica-shape triple burner ignites within 3 to 5 seconds, delivering the same 20 kilowatts of heating power regardless of whether the incoming pressure is timid or robust.

Specifications

The compact 590-by-340-by-180-millimetre unit weighs just 8 kilograms net, easing installation in high-rise apartments where lifting heavy equipment up staircases or through narrow service lifts creates unnecessary complications. The rated 20-kilowatt heat input pairs with an oxygen-free copper heat exchanger to achieve thermal efficiency above 85 percent, producing a stable 10 litres per minute at a 25-degree Celsius rise. Working water pressure officially ranges from 0.025 to 0.8 megapascals, but the low-pressure startup mechanism engages reliably at just 0.015 megapascals, giving upper-floor residents an unusually generous operating envelope. Fuel input accepts both LPG at 2800 pascals and natural gas at 2000 pascals through a G1/2 inch gas connection, with matching G1/2 inch water inlet and outlet threads.

Technical Parameters

Installation Scenarios & Installation Precautions

High-rise apartments above the tenth floor, walk-up buildings without booster pumps, older residential neighbourhoods with ageing municipal supply, rural farmhouses with rooftop water tanks, and mountain-region homes with gravity-fed spring water all benefit dramatically from the low-pressure startup capability. Install on a sound kitchen or balcony wall with the flue routed to a proper outdoor termination — the 90-millimetre chimney diameter accepts standard residential ducting materials available in most regional hardware markets. Because the unit relies on natural draft rather than a forced exhaust fan, avoid installation locations that experience strong reverse wind pressure such as directly beneath overhangs or in enclosed light wells. Confirm gas line sizing is adequate for the 20-kilowatt input, and verify that the incoming water supply is filtered against sediment that could clog the sensitive low-pressure valve mechanism.

Features & Value Delivered to Global Buyers

The feature set centres on solving real-world water pressure problems: low-water-pressure startup at 0.015 megapascals, over-pressure protection to guard the unit when municipal pressure spikes, flame-failure protection, anti-dry burning protection, overheat cutoff, and the 20-minute automatic shutoff timer. What sets this unit apart from budget alternatives is the specifically engineered water-control linkage valve, which uses precision-machined internal components rather than the stamped-metal parts common in imports that fail to actuate at low flow. Distributors serving markets with weak municipal infrastructure, including Central Asia, parts of South America, and rural regions across South and Southeast Asia, find this capability transforms hard-to-serve customer segments into satisfied buyers.

Safety Boundaries & Long-Term Use Reminders

This heater is not designed for use with pressurised pump systems that exceed 0.8 megapascals without an installed pressure reducing valve upstream. It cannot compensate for zero incoming flow — even the low-pressure startup requires some minimum water movement to trigger the linkage valve. Do not install in sealed bathrooms, and ensure the flue path remains unobstructed by leaves, snow, or bird nests that could block natural draft. In hard water regions, prioritise inlet filter maintenance every ninety days to keep the sensitive low-pressure valve free of sediment. If the ignition delay progressively lengthens beyond the normal 3-to-5-second window, inspect both the DC 3V battery voltage and the pulse ignitor electrodes for wear before assuming the low-pressure valve itself has failed.
