Providing a reliable source of hot water is a fundamental requirement for a comfortable life on the inland waterways. For many narrowboat owners, an LPG-powered instant water heater is the most technically efficient solution, as it provides hot water on demand without the need to run the engine or deplete a limited domestic battery bank. At Marine Heating Solutions, we specialise in the professional integration of specialist hot water systems, ensuring that your galley and shower installations are both high-performing and safe.

The Specialist Difference: Professional Water Heating Integration

Installing a gas water heater in the confined environment of a boat requires a precise engineering approach to manage combustion air and flue gas exhaust. Our technical services ensure that your water heater kit is part of a holistic, BSS-compliant gas system.

• Correct Flue Termination: We ensure that all water heater kits include the correct vertical or balanced flue kits to prevent CO ingress into the cabin.
• Pressure-Balanced Performance: Our installations account for the vessel’s water pump pressure and flow rates, ensuring the burner ignites reliably even at lower domestic pressures.
• Marine-Grade LPG Connections: We utilise mechanical joints and vibration-resistant copper pipework to prevent gas leaks in the challenging environment of a moving vessel.

Safety/Regulatory: OFTEC, GasSafe, and Canal & River Trust (CRT)

To maintain your Canal & River Trust (CRT) license, your water heater must pass the Boat Safety Scheme (BSS) inspection. This involves checking for correct flueing, adequate ventilation, and the presence of a dedicated gas isolation valve.

As GasSafe registered engineers with marine competencies, we certify that every water heater installation complies with BS EN ISO 10239:2025. Our “right first time” philosophy ensures your system adds value to your vessel while providing safe, reliable hot water for your crew.
