Picking the right heater for your boat is what turns a seasonal hobby into a year-round passion. In the UK, the main contenders for 2026 remain diesel, LPG, and solid fuel systems.
1. Forced Air Diesel Heaters: The Popular Choice
Diesel heaters are the most popular choice for liveaboards because they produce a very dry heat, which is the best defence against boat condensation.

2. LPG Gas Heaters: Quiet and Convenient
LPG heaters are prized for being quiet and convenient, especially if you already use gas for cooking. They deliver warmth almost instantly, taking the chill off a cabin in minutes.

3. Solid Fuel Stoves: The Traditional Heart
Nothing beats the unique, radiant warmth and cosy glow of a real fire. These are the traditional choices for narrowboats and off-grid cruisers.

4. The Non-Negotiable Priority: Safety
Regardless of which system you choose, safety must be the foundation of the installation. Ensure your engineer is properly qualified for marine work and that a working, marine-grade CO alarm is installed.
