Meet the Suburban 20.3ltr Gas Water Heater Kit (Blackdoor) — a compact, reliable hot-water solution designed for caravans, motorhomes, and compact living spaces where easy installation and effortless maintenance matter most. This kit brings home-style comfort to off-grid or mobile setups without sacrificing performance.

• Outside-in installation and serviceability: Designed for simple mounting and operation from outside. A removable outer door hides the essential controls while giving you quick access to the limit switch, reset button, and the combined drain plug/anode rod for fast servicing.
• Durable, long-life tank: Porcelain-lined steel tank with a sacrificial anode protects against electrolytic action, helping extend the system’s life. The anode should be checked annually and typically lasts 2–3 years before replacement is needed.
• Rapid hot-water recovery: Delivers up to 40 L per hour at a 45°C temperature rise, so showers and hand-washing keep pace with everyday use.
• Compact footprint, solid build: Measures 320 mm (H) × 320 mm (W) × 490 mm (D) with an allowance of ~50 mm for plumbing fittings. Weighs 15 kg, making it suitable for tight installations in mobile spaces.
• 12V ignition and easy operation: A wall-mounted 12V electronically ignites the burner, delivering dependable hot water with simple, user-friendly controls.
• Complete installation kit included: Comes with 12 mm John Guest fittings and all necessary components to get you up and running. Note: pump pressure must not exceed 45 PSI, and installation must be performed by a qualified gas fitter.
• Specifically configured for gas heating: Heat source is gas only, with a setpoint of 54°C and a burner rating of about 12,000 BTU (roughly 4 kW), ensuring comfortable, consistent water temperature.
• Inlet and connections: Water inlet uses a 1/2" BSP female thread for straightforward plumbing connections.
