A boat stove is more than just a heating appliance; for many liveaboards, it is the heart of the home. However, the confined space and constant movement of a vessel place extreme stress on stoves and their flue systems.

At Marine Heating Solutions, our OFTEC-trained technicians specialise in the intricate maintenance required for both solid fuel (wood/coal) and vaporising diesel stoves (like Morso, Bubble, and Refleks).


Why Professional Servicing is Essential

Many boat owners believe a quick sweep of the flue is enough. True marine stove servicing goes deeper:

  • Integrity Checks: We inspect the stove body for cracks or warped plates that can leak deadly Carbon Monoxide.
  • Flue Performance: We test the “draw” to ensure your stove isn’t back-filling the cabin with fumes during high winds.
  • Efficiency: For diesel stoves, a clean burner pot and calibrated Toby valve can significantly reduce your winter fuel bill.
  • BSS Compliance: We ensure your installation meets the current Boat Safety Scheme (BSS) standards for fire safety and ventilation.

1. Solid Fuel Stove Maintenance (Wood & Coal)

Solid fuel stoves take a beating from high temperatures and corrosive ash. Our annual service ensures your stove remains a safe, efficient heat source.

Our Solid Fuel Service Includes:

  • Baffle Plate & Firebrick Inspection: Checking for damage that can cause the stove body to overheat.
  • Rope Seal Replacement: Ensuring the door is airtight to prevent uncontrolled “runaway” fires.
  • Glass Deep Clean: Removing stubborn creosote to restore your view of the fire.
  • Grate & Ashpan Check: Ensuring proper airflow for efficient combustion.

2. Diesel Stove & Cooker Servicing (Vaporising Burners)

Vaporising diesel stoves (Refleks, Bubble, Dickinson) require a different set of engineering skills. These stoves rely on precise fuel flow and a clean “catalyst” to burn blue and soot-free.

Key Technical Tasks:

  • Toby Valve Calibration: We use precision tools to set the minimum and maximum fuel flow rates.
  • Catalyst Ring Alignment: Ensuring the shells and rings are positioned for a perfect “vortex” flame.
  • Fuel Line Flushing: Removing the “clinker” and carbon deposits that block gravity-fed lines.

3. Flue Systems and Back Boilers

The flue is the most dangerous part of any boat stove installation. If it isn’t insulated or swept correctly, you risk a chimney fire or tar leakage.

Our Expertise Includes:

Insulated twin-wall flues are essential for safety on boats, maintaining the correct internal temperature to ensure a strong stove “draw” and preventing external heat transfer to the cabin roof.
