Read moreEnsuring 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.
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.
We provide installation and support for the industry’s most trusted brands, ensuring your kit is matched to your vessel’s specific power and space requirements:

Webasto: Renowned for German engineering, Webasto systems offer quiet, stepless heating and advanced digital integration via the MultiControl or ThermoConnect app

Wallas: Features “Greenboost” laminar burning technology for ultra-low emissions and the quietest operation on the market. Ideal for eco-conscious boaters.

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.
