Ensuring reliable warmth during a British winter requires more than just a generic heater; it requires a system specifically engineered for the unique layout of a 30 to 70-foot vessel.2 Our selection of marine-grade heating solutions is curated to provide consistent, dry heat through the long cabin runs typical of narrowboats. Unlike “budget” kits found online, a professional-grade kit prioritises fuel integrity, silent operation, and long-term reliability under the demanding conditions of the inland waterways.

The Specialist Difference: Professional Kits vs. Generic Imports

When selecting a heating system, the initial purchase price is only one factor. A professional installation focused on engineering precision ensures that your heater operates at peak efficiency for years, rather than months.

  • Marine-Specific Components: Professional narrowboat kits include heavy-duty stainless steel exhaust systems, marine-grade fuel lines, and high-quality silencers that meet mandatory safety standards.3
  • Optimal Airflow: Narrowboats present unique challenges for ducting. A specialised kit ensures the blower fan is matched to the length of your cabin to prevent overheating and ensure even heat distribution from bow to stern.
  • Reduced Carbon Sooting: High-tier heaters from Webasto and Wallas use advanced combustion control to minimise carbon buildup, a common cause of failure in cheaper, uncertified alternatives.

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

To maintain your Canal & River Trust (CRT) license, all diesel heating systems must adhere to the Boat Safety Scheme (BSS) requirements. This includes specific mandates for exhaust routing to prevent Carbon Monoxide (CO) ingress and the use of ISO 7840 compliant fuel hoses.

At Marine Heating Solutions, we strongly recommend that all kits are commissioned by an OFTEC registered technician. Our “right first time” approach ensures that your installation meets BS 8511 standards, preventing costly re-tests during your BSS inspection and ensuring the safety of everyone on board.
