How to Bleed a Narrowboat Heating System: A Step-by-Step Guide
As the 2026 winter season settles across the UK inland waterways, a common frustration for many boaters is a heating[…]
Read moreDiesel-powered appliances provide a high-output, single-fuel solution for both climate control and galley requirements on inland waterway vessels. By utilising the vessel’s primary fuel supply, these systems offer exceptional autonomy for off-grid cruising, provided they are engineered to handle the specific challenges of marine fuel delivery and DC power consumption. At Marine Heating Solutions, we provide specialised engineering support to ensure your diesel heating and cooking systems operate reliably without the common risks of “coking” or electrical interference.
Our service model is built on preventing technical failures before they occur. For diesel systems, this means precise calibration of fuel-to-air ratios and the use of specialised diagnostic tools to ensure clean combustion across all power settings.
We provide professional integration for the latest generation of diesel-fired boat heating and cooking systems. This includes specialised servicing for technical diesel heating systems and diesel-fired hobs like the Webasto Cooktop 1900, which eliminates the need for LPG on board. To ensure your system remains operational throughout the winter, read our technical guide on how to service a diesel heater.
All diesel-fired installations must be documented and compliant with the Boat Safety Scheme (BSS) to maintain your Canal & River Trust (CRT) license.

As OFTEC-registered technicians and GasSafe marine engineers, we provide the legal certification required for your insurance and four-yearly BSS examinations. Our recognised status with the Canal & River Trust ensures that our installations meet the specific fire-containment and ventilation standards required for inland waterway vessels.
A diesel-fired galley and heating system requires robust supporting networks. We provide specialised integration for marine plumbing systems, including calorifiers linked to hydronic diesel boilers, and marine electrical services to ensure your battery bank can support the high-current startup phases of diesel combustion.
