Expert boat stove maintenance is the cornerstone of a safe, warm, and inviting home on the UK’s canals. Beyond simple comfort, professional servicing prevents catastrophic failures and ensures your appliance remains compliant with the Boat Safety Scheme (BSS). As we look toward the 2026 season, maintaining your heating system’s integrity is more critical than ever.


The Hidden Dangers of Neglected Maintenance

A boat stove is not a household heater; it operates in a high-vibration, high-moisture environment that accelerates wear on gaskets, flues, and fuel lines. Neglecting maintenance can lead to:

  • Carbon Monoxide (CO) Poisoning: Often caused by cracked flues or perished door seals.
  • Chimney Fires: Resulting from excessive soot and creosote buildup in the flue system.
  • Fuel Leaks: Particularly in diesel systems, which can lead to fires.

Solid Fuel Stove Maintenance (Wood & Coal)

For traditional multi-fuel stoves like the Chilli Penguin or Morso Squirrel, maintenance focuses on the integrity of the combustion chamber.

  1. Gasket Replacement: Door seals should be “paper-test” tight. If they are hard or frayed, they must be replaced to prevent uncontrolled air intake.
  2. Firebrick Inspection: Cracked firebricks can cause the outer casting to overheat and crack.
  3. Flue Sweeping: Monthly sweeping is recommended for full-time live-aboards.

Diesel Boat Stove Servicing

Diesel stoves, such as those from Refleks or Bubble, require a different technical approach. Unlike solid fuel, these depend on precise fuel calibration and clean burner assemblies.

Our diesel heater installation and maintenance service includes a full strip-down of the burner to remove carbon deposits. We also calibrate the fuel flow to ensure you are getting the maximum kW output for your fuel consumption.


Safety Standards & Outbound Verification

To ensure your maintenance meets strict UK legal requirements, our engineers are fully OFTEC certified. This is the premier certification for both solid fuel and diesel appliances, ensuring every service we perform exceeds the safety expectations of the Boat Safety Scheme (BSS). Using an uncertified engineer or one without specific marine-grade expertise not only risks your safety but can also invalidate your marine insurance policy.


Our Meticulous Stove Maintenance Process

When you book a professional service with Marine Heating Solutions, you aren’t just getting a “clean”. Our process is a comprehensive engineering audit tailored to the unique demands of marine heating:

  • Fuel System Integrity (Diesel): For diesel stoves like Refleks or Bubble, we meticulously inspect every inch of the fuel line for wear, corrosion, or leaks.
  • Calibration & Flow Testing: We test and adjust fuel valves to ensure correct flow rates, which is vital for efficient combustion and preventing performance headaches.
  • Combustion & Flue Audit: We perform a complete audit of the burner assembly, identifying carbon deposits that hamper performance and safety.
  • Spillage & Flue Integrity: We verify that all combustion products are exiting via the flue—not into your cabin—by inspecting the flue for blockages or weaknesses an untrained eye would miss.
