Natural Gas Flue Gas Water Heater Featuring Automatic Electronic Pulse Ignition and Wall Hanging Installation Designed for Energy

Natural Gas Flue Gas Water Heater Featuring Automatic Electronic Pulse Ignition and Wall Hanging Installation Designed for Energy

Product Description

Secondary bathrooms, guest suites, and mother-in-law apartments often present a hot water dilemma: the primary household heater is too far away for practical delivery, but a full-scale second heater feels excessive for the light usage these zones typically see. Our 10L Flue Type Instant Gas Water Heater solves this precisely, occupying just 590 by 340 by 180 millimetres of wall space while delivering enough capacity for the occasional guest shower, weekend visitor cleanup, or dedicated pet-washing setup. The 20-kilowatt burner ignites within 3 to 5 seconds and produces the same 10-litre-per-minute flow as heaters dedicated to primary bathrooms, so the secondary user experience never feels like a compromise. Because the unit runs on battery-powered ignition rather than mains electrical, it can be installed in supplementary spaces without adding electrical circuit complications.

Specifications

The slim 180-millimetre depth allows mounting in tight utility niches, behind pocket doors, or above laundry equipment where deeper units would interfere. Net weight of 8 kilograms keeps installation manageable for a single technician on a stepladder, and packed shipping weight of 9 kilograms in a 670-by-405-by-230-millimetre carton fits standard courier services for direct-to-site delivery. The 20-kilowatt harmonica-shape triple burner feeds an oxygen-free copper heat exchanger, achieving thermal efficiency above 85 percent and stabilising outlet temperature within 15 seconds of ignition. Water pressure tolerance covers 0.02 to 0.8 megapascals, the temperature knob adjusts from 35 to 80 degrees Celsius, and a G1/2 inch gas connection accepts LPG at 2800 pascals or natural gas at 2000 pascals depending on configuration.

Technical Parameters

Installation Scenarios & Installation Precautions

Guest bathrooms with dedicated service areas, mother-in-law apartments above garages, converted attic bedrooms with ensuite facilities, holiday-let secondary bathrooms, and dedicated pet-washing utility rooms all suit this compact backup application. Install with the flue routed to an exterior wall through the shortest practical path, since long horizontal flue runs can compromise natural draft in secondary installations that may sit unused for days between activations. Because the space may be closed off when unused, verify that combustion air can enter freely whenever the unit operates — an undercut door, ventilation grille, or operable transom window all suffice. Never allow the installation location to be sealed for storage purposes, and post a clear sign warning against closing air pathways if others might access the space.

Features & Value Delivered to Global Buyers

Practical features suit the backup use case: low-water-pressure startup that engages reliably even when the unit has sat dormant for days, dual pulse ignition pins that fire consistently despite intermittent use, flame-failure protection, over-pressure protection, anti-dry combustion, overheat cutoff, and the 20-minute timer that prevents runaway operation if a guest forgets to close a tap. What sets this unit apart from budget alternatives in the secondary-installation category is a specifically engineered battery management system that preserves ignition power through extended idle periods, achieving the promised one-year battery service life even in installations that operate only a few times per week. OEM buyers can specify housing colour, panel material, and knob layout to match secondary-space aesthetics.

Safety Boundaries & Long-Term Use Reminders

This unit is not designed for installation in truly enclosed guest bathrooms without independent ventilation, and it cannot substitute for a primary household heater in high-demand applications. Because backup installations may see extended idle periods, inspect the DC 3V battery voltage every six months rather than waiting for the standard annual replacement cycle, since batteries can discharge slowly even without active use. Test the ignition sequence monthly by opening a tap briefly, listening for the pulse ignition click, and confirming the burner fires within the expected 3-to-5-second window. If the unit will remain unused for more than one month, close the gas supply valve upstream to prevent any possibility of minor leakage during the dormant period, and drain the water circuit in freeze-risk climates.
