10L Instant Constant Temperature Gas Water Heater | 21kW Wall-Mounted NG Boiler with ±0.5°C Precision & Copper Coil

Product Description

Living in a compact urban apartment should never mean settling for cold showers or waiting endlessly for hot water to arrive. Our 10L Instant Constant Temperature Gas Water Heater redefines what residents in space-constrained homes can expect from their daily bathing routine. Unlike bulky storage tanks that consume precious floor area and continuously bleed heat into the surrounding air, this wall-mounted unit activates only when water flows, delivering instant warmth without the energy penalty of standby losses. A 21kW combustion core generates sufficient thermal energy to raise water temperature by 25 degrees Celsius at a steady 11 liters per minute, ensuring that even during the busiest morning routines, the last family member enjoys the same comforting warmth as the first. The intelligent proportional valve works in tandem with a high-response temperature sensor to maintain outlet stability within half a degree, eliminating the jarring temperature swings that disrupt relaxation and create safety concerns for households with young children or elderly members.

Technical Parameters

Specifications

Engineered around a 530-by-330-by-143 millimeter chassis, this heater occupies minimal wall real estate while housing a genuine oxygen-free copper heat exchanger that outperforms aluminium-plated alternatives in both thermal transfer efficiency and long-term durability. The unit achieves thermal efficiency exceeding ninety-three percent under standard test conditions, a figure that translates directly into lower monthly gas bills compared to conventional atmospheric models. Operating pressure tolerance spans from 0.02 to 0.8 megapascals, accommodating both ground-floor residences with strong municipal pressure and upper-floor apartments where supply naturally diminishes. Natural gas feeds through a standard G1/2 inch connection at 2000 pascals, with electronic ignition eliminating the pilot light waste common in older designs. The forced exhaust system routes combustion products through flue diameters of 50, 60, or 90 millimetres, adapting to various building configurations and local ventilation codes.

Installation Scenarios & Installation Precautions

This model finds its natural home in studio apartments, converted loft spaces, and compact service balconies where every square metre commands premium value. Installation against an exterior wall allows direct flue penetration to the outside environment, while semi-enclosed kitchen alcoves provide adequate combustion air when properly ventilated. Before mounting, verify that the wall substrate can support the unit's weight plus dynamic loads from water hammer and thermal expansion. Maintain a minimum two-hundred-millimetre clearance above the top cover and one-hundred-fifty millimetres on both lateral sides to facilitate future servicing. The flue terminal must terminate at least six hundred millimetres from any window, door, or air intake grille to prevent combustion product recirculation. Never install inside a fully enclosed bathroom, bedroom, or walk-in wardrobe where oxygen depletion and carbon monoxide accumulation pose lethal risks. All gas connections require testing with soapy water or electronic leak detection equipment before commissioning.

Features & Value Delivered to Global Buyers

The constant-temperature algorithm represents the heart of this unit's appeal, continuously adjusting gas flow to match real-time demand rather than cycling between full-on and off states. Flame-failure protection severs fuel supply within three-tenths of a second if the burner extinguishes unexpectedly, while an overheat safeguard triggers at 176 degrees Fahrenheit to prevent dangerous temperature escalation. For OEM and wholesale partners, the platform supports extensive customization including silk-screen logo application, full-colour housing finishes, LED display variants, and optional protection modules tailored to regional certification requirements. A forty-foot high-cube container accommodates seven hundred eighty pieces, enabling competitive landed costs for volume importers. Standard warranty coverage extends one year from installation date, supplemented by complimentary spare parts equivalent to one percent of total order quantity and comprehensive technical documentation for installer training.

Safety Boundaries & Long-Term Use Reminders

This appliance is not intended for installation in unheated outdoor locations where ambient temperatures drop below freezing without dedicated freeze-protection accessories. It cannot accept gas supplies operating outside the specified pressure ranges without factory recalibration. Continuous industrial-scale operation beyond normal residential duty cycles will accelerate component wear and void warranty coverage. During daily use, avoid directing water spray toward the touch panel, keep flammable materials at least three hundred millimetres from the unit surface, and never attempt to bypass any safety interlock. Prior to extended winter shutdown, drain the internal water circuit completely to prevent ice formation within the copper coil. In regions with high sediment content, inspect and clean the inlet filter screen every ninety days to preserve rated flow capacity and prevent premature heat exchanger fouling.
