Product Description

Replacing an ageing storage tank with a tankless system is one of the highest-return upgrades available to a homeowner, yet many hesitate because they assume the conversion demands structural work and extensive replumbing. Our 10L Instant Constant Temperature Gas Water Heater is dimensioned and specified to make that transition straightforward. At 530 by 330 by 143 millimetres it occupies a fraction of the volume a 40 to 60 litre tank consumed, freeing the floor area beneath for storage or simply for breathing room. Standard G1/2 inch connections align with existing residential plumbing conventions, and the 21kW output paired with an oxygen-free copper exchanger delivers a hot water experience that immediately outperforms the tank it replaced — no reheat waiting, no temperature decay, no standby energy loss.

Specifications

The plate iron enclosure carries an IPX2 waterproof rating suited to the utility spaces where old tanks typically lived. Efficiency exceeding 93 percent contrasts sharply with the 60 to 70 percent effective figures common in ageing tank units once standby losses are accounted for. Natural gas at 2000 pascals enters through a G1/2 inch inlet with consumption of 2.06 cubic metres per hour, yielding 11 litres per minute at a 25-degree Celsius rise. Working water pressure accommodates 0.02 to 0.8 pascals, which matters in older properties where supply pressure has degraded over decades. Temperature control operates from 35 to 80 degrees Celsius via touch panel, electronic ignition replaces any pilot arrangement, and forced exhaust venting accepts 50, 60, or 90 millimetre flues on 220V power.

Technical Parameters

Installation Scenarios & Installation Precautions

Retrofit projects in mid-tier apartments form the primary application, along with older single-family homes, converted terraced houses, and staff dormitories undergoing modernisation. The wall-mounted format allows installation above the footprint the tank previously occupied, often reusing existing water connections with minor adaptation. Before mounting, inspect the wall carefully — older construction may need reinforcement where a tank previously sat on the floor and imposed no wall load. Establish 200 millimetres of clearance above the unit and 150 millimetres on both flanks, verify that the existing flue penetration suits one of the three supported diameters or plan a new one, and keep the terminal 600 millimetres from any opening. Test every gas connection with soap solution, and never repurpose an enclosed bathroom cupboard as the new installation location.

Features & Value Delivered to Global Buyers

The unit delivers constant temperature output within ±0.5°C, flame failure protection, 176-degree Fahrenheit overheat protection, electronic ignition, and LED touch-panel control. Our competitive advantage rests on three pillars: an oxygen-free copper heat exchanger that outlasts plated alternatives in retrofit environments where water quality is often poorer, verified thermal efficiency above 93 percent that produces immediately visible savings against the replaced tank, and 780 pieces per 40HQ container for distributors serving renovation markets. OEM options include silk-screen branding, any housing colour, flue diameter matching to existing penetrations, display variants, and additional protection modules. Commercial support covers a one-year warranty, one percent free spare parts, and installer-oriented documentation.

Safety Boundaries & Long-Term Use Reminders

Retrofit installations carry particular constraints: this unit is not suitable for reuse of undersized gas lines that served a lower-input tank, not designed for recessed cupboard mounting without ventilation clearance, and not intended for gas supplies outside the specified pressure bands without factory reconfiguration. Confirm local gas type and voltage compatibility before purchase rather than after delivery. During operation, never disable any safety protection module, avoid directing water spray at the control panel, and ensure everyone in the household knows the emergency shutoff location. Schedule the first professional inspection twelve months after commissioning to verify that legacy plumbing debris has not accumulated in the inlet filter, and clean that filter every three to six months thereafter.
