Optional Protection Tankless Gas Water Heater Offering Thermal Efficiency ≥85

Optional Protection Tankless Gas Water Heater Offering Thermal Efficiency ≥85 Percent Designed for Continuous Hot Water Delivery

Product Description

Remote holiday properties require equipment that can sit idle, restart reliably, and operate even when the local grid is unavailable. This 10L flue type instant gas water heater meets that pattern with DC 3V battery ignition, LPG compatibility, and on-demand heating that consumes no fuel between guest stays. Opening a tap activates the water-gas linkage, dual ignition pins light the 20-kilowatt three-section burner, and the copper heat exchanger delivers approximately 10 litres per minute at a 25-degree Celsius rise. That output suits one residential shower or washing point at a time, while the adjustable 35-to-80-degree range covers warm island inlet water and cooler shoulder seasons. For coastal projects, stainless-steel or protected coated panels can be specified instead of choosing a finish solely for showroom appearance. The natural-draft design remains straightforward to service with common 90-millimetre flue components, provided the installer controls salt exposure, wind pressure, and ventilation correctly.

Specifications

The heater measures 590 by 340 by 180 millimetres and has a typical net weight of 8 kilograms. Its export package measures 670 by 405 by 230 millimetres and weighs about 9 kilograms gross. A rated 20-kilowatt burner works with a copper exchanger to provide at least 85 percent thermal efficiency and nominal delivery of 10 litres per minute at the reference rise. Water pressure may range from 0.02 to 0.8 megapascals, and low-pressure ignition can begin near 0.015 megapascals. LPG units require 2800 pascals, while natural-gas versions are prepared for 2000 pascals. DC 3V batteries power pulse ignition, and all water and fuel ports use G1/2-inch threads. The harmonica-shaped burner has three sections, heating begins within 15 seconds under correct conditions, and a 90-millimetre chimney carries exhaust outdoors.

Technical Parameters

Installation Scenarios & Installation Precautions

This configuration suits island cottages, fishing lodges, off-grid villas, coastal guesthouses, and covered service balconies serving one main outlet. Install beneath a roof in a ventilated kitchen or utility area where direct rain and salt spray cannot reach the cabinet. A screened louvre or operable window must provide permanent replacement air, and the 90-millimetre chimney should use corrosion-resistant components with minimal horizontal run. Never mount the unit in a sealed bathroom, bedroom, storage cupboard, or enclosed courtyard where exhaust can recirculate. Verify wall strength, leave 200 millimetres above and 150 millimetres on both sides, and position LPG cylinders outdoors in a secure ventilated cage. Leak-test connections and observe flame stability under normal coastal wind before handover.

Features & Value Delivered to Global Buyers

The island-use value combines grid-independent ignition, low-pressure activation for header tanks, and panel options selected for the operating environment. Dual electrodes, flame-loss shutdown, anti-dry protection, overheat and pressure controls, seasonal adjustment, and a 20-minute timer support guest operation. OEM buyers may define finish, coating, colour, local-language controls, branding, display, and protective packaging. MOQ begins at 100 pieces per model, sample units allow site trials, and regular production follows approval and deposit. The one-year warranty is backed by free routine service parts for local property teams or distributors.

Safety Boundaries & Long-Term Use Reminders

A corrosion-resistant panel does not make the appliance suitable for open rain, and island breezes do not replace controlled ventilation. Stop use if storms damage the chimney or repeated gusts disturb combustion. Close LPG valves between long vacancies and never store cylinders indoors. Wipe salt residue with a soft damp cloth, inspect flue joints and fasteners for corrosion, clear insect or bird nests, and verify blue flame before a new guest season. Replace batteries proactively each year, clean the inlet filter, and drain the heater if the property closes during freezing conditions.
