Gas Pressure NG2000Pa LPG2800Pa Flue Gas Water Heater Featuring Copper Heat Exchanger and 60mm Chimney Size Suitable for Commercial

Product Description

A short wait can feel much longer when someone is standing at a cold shower tap, especially in compact homes where hot water is needed several times throughout the day. This 6L flue type instant gas water heater converts flowing water into usable hot water within a heating window of no more than 15 seconds under suitable supply conditions. There is no storage tank to refill and no reservoir losing heat between uses. Water movement activates the internal linkage, two ignition pins initiate combustion, and the three-section harmonica burner directs its 12-kilowatt input across the copper heating surface. The result is a practical 6-litre-per-minute supply intended for a single shower, basin, or kitchen draw. Rotary controls allow users to respond to changing inlet temperature and flow rather than relying on a fixed output setting. Because the pulse ignitor runs from a DC 3V battery pack, the heating sequence remains independent of household mains electricity, an advantage in regions where outages interrupt electrically controlled appliances.

Specifications

At 440 millimetres high, 300 millimetres wide, and 120 millimetres deep, the heater occupies little wall area and remains easy to position near the intended outlet. The 12-kilowatt rated input works with an oxygen-free copper heat exchanger to deliver at least 84 percent thermal efficiency. Approximate hot-water production is 6 litres per minute at a 25-degree temperature rise, with an adjustable range from 30 to 55 degrees Celsius. Heating time is specified at 15 seconds or less, outlet overshoot at no more than 2 degrees Celsius, and stabilisation at 15 seconds or less when pressure and flow meet operating requirements. The accepted water-pressure band runs from 0.02 to 0.8 megapascals. LPG models operate at 2800 pascals, while natural-gas models use 2000 pascals. Standard G1/2-inch threaded ports simplify water and fuel connection, and a 90-millimetre chimney carries exhaust by natural draft.

Technical Parameters

Installation Scenarios & Installation Precautions

The rapid-heating format works well in compact household kitchens, secondary wash areas, ventilated balconies, staff accommodation, and small holiday properties where a single outlet is used at a time. Positioning the appliance close to the shower or basin shortens the pipe run and reduces the separate delay caused by cold water sitting inside long plumbing lines. The unit must still remain outside the bathroom itself unless the proposed location is a separately ventilated service area that complies with local regulations. A smoke pipe is mandatory and must discharge outdoors. Maintain a reliable air inlet through an operable window or permanent grille, avoid enclosed light wells that may create reverse pressure, and keep the chimney route mainly vertical. The wall must support the operating load, with 200 millimetres of free space above and 150 millimetres at each side. Complete a leak test and confirm the ordered fuel calibration before use.

Features & Value Delivered to Global Buyers

What sets this unit apart from slower, tank-based alternatives is the direct relationship between water movement and heat production. Dual-pin pulse ignition, a water-gas interlock valve, low-pressure activation, and a three-section burner help the sequence begin promptly, while four protection functions supervise flame loss, dry operation, excess heat, and excessive water pressure. A 20-minute limiter adds protection against an unattended open tap. For wholesale programs, the heater can be supplied with coated metal, stainless-steel, or glass fascia options, different colours, branded printing, and LED or LCD temperature indication. Manufacturers and distributors can begin with 100 pieces per model, receive sample units before volume production, and obtain complimentary service components with the shipment under a one-year warranty arrangement.

Safety Boundaries & Long-Term Use Reminders

The stated heating time depends on correct fuel pressure, suitable water flow, short outlet pipework, and proper burner condition; it should not be presented as an identical result in every installation. Do not operate the heater without an exterior flue, place it in a sleeping area, or use it where combustion air can be shut off. Never bypass the water-gas linkage or any protective sensor. If ignition begins taking longer than normal, inspect battery condition and electrode cleanliness rather than repeatedly opening the tap. Service the burner annually, clear the chimney terminal of debris, clean the inlet screen in sediment-prone areas, and drain the water circuit before a long winter closure.
