Thermal Efficiency 85 Percent Or More Tankless Gas Water Heater Offering Customer Customization Suitable For Commercial

Product Description

Rental-property renovations reward appliances that fit existing service spaces, remain understandable to new occupants, and reduce the cost of ordinary turnover. This 10L flue type instant gas water heater combines a compact wall-mounted body with a 20-minute operating limit and battery-powered ignition. It can replace a failed tank where ventilation and an exterior chimney route are available, removing the storage vessel without requiring a mains supply for the ignition circuit. Water flow activates the interlock, DC 3V pulses light the triple burner, and 20 kilowatts of input pass through the copper heat exchanger. Around 10 litres per minute is delivered at a 25-degree Celsius rise for one shower or washing outlet. Controls adjust from 35 to 80 degrees Celsius, giving the installer a clear commissioning range for each property. The timer interrupts an unusually long uninterrupted cycle, while standard G1/2-inch ports and a 90-millimetre chimney simplify future replacement planning across a rental portfolio.

Specifications

The cabinet measures 590 by 340 by 180 millimetres, with a 145-millimetre-depth version available on selected models. Typical net weight is 8 kilograms and packed weight approximately 9 kilograms in a 670-by-405-by-230-millimetre carton. Rated thermal input reaches 20 kilowatts and efficiency is at least 85 percent. Nominal output is 10 litres per minute at the specified rise. Water pressure may range from 0.02 to 0.8 megapascals, with ignition possible near 0.015 megapascals. LPG versions are prepared for 2800 pascals, while natural-gas versions use 2000 pascals. The DC 3V pulse system uses two electrodes, heating starts within 15 seconds under suitable conditions, and all water and fuel connections use G1/2-inch threads. Natural exhaust connects through a 90-millimetre collar.

Technical Parameters

Installation Scenarios & Installation Precautions

Suitable projects include older rental apartments with ventilated kitchens, townhouse refurbishments, small landlord portfolios, secondary service balconies, and annex conversions with one principal outlet. Do not reuse a former tank cupboard automatically. The proposed position needs permanent combustion air and a compliant outdoor route for the smoke pipe. Sealed bathrooms, bedrooms, stairs, closed closets, and spaces without an independent air path are unacceptable. Check the wall, leave 200 millimetres above and 150 millimetres beside the casing, flush debris from old plumbing, and replace worn hoses or regulators. Keep the flue mainly vertical, verify LPG or natural-gas calibration, test joints with soap solution, and record shutoff locations for tenants and property managers.

Features & Value Delivered to Global Buyers

The rental value combines retrofit flexibility, straightforward controls, timed protection, and common service items. Flame-loss shutdown, anti-dry protection, overheat and pressure safeguards, low-pressure startup, dual ignition pins, and water-gas interlock support changing occupants. Property brands or distributors may customise panel finish, colour, control graphics, display, logo, and carton. MOQ begins at 100 pieces per model, samples permit pilot installations, and regular production follows approval and deposit. A one-year warranty with free routine parts helps maintenance teams avoid complete-unit replacement for small failures.

Safety Boundaries & Long-Term Use Reminders

A landlord must not select this heater solely because it fits the wall. Ventilation, chimney route, gas type, pressure, and local rules require professional assessment for every property. The timer must not be defeated, and tenants should receive written instructions. Never install in sleeping areas, sealed bathrooms, or direct rain. Inspect the unit at each tenancy change, replace batteries annually, clean the inlet screen, verify blue flame, examine the chimney, and close the gas supply until service is completed after odour, heat damage, or repeated shutdown.
