For many boaters, the ritual of running the engine just to get a basin of hot water is too inefficient. An LPG water heater is a sensational game-changer for life on a narrowboat, providing instant, reliable hot water whenever you need it without firing up the engine. This on-demand convenience transforms daily life, making galley chores and morning showers feel like a true luxury.
Why Upgrade to a Modern Marine LPG Water Heater?
Traditional calorifiers can be slow and often rely on engine heat or shore power. In contrast, modern water heaters are built specifically for the marine world—compact, surprisingly efficient, and delivering hot water on demand. Because these units only use fuel at the exact moment you turn on the tap, they drastically reduce your gas consumption compared to older, storage-based systems.
Professional Setup: The Key to Narrowboat Safety
When dealing with gas appliances in the confined space of a boat, safety is non-negotiable. At Marine Heating Solutions, our Gas Safe-registered engineers ensure every installation meets the UK’s strict marine safety standards. We understand the critical nuances of correct ventilation, secure pipework, and flue integrity that keep your family safe. For independent verification of safety requirements, you should consult the Boat Safety Scheme (BSS) gas core requirements.

Selecting the Right Model for Your Vessel
Choosing the right heater depends on your usage habits and boat size. A weekend boater has different needs than a family living aboard full-time. We help you navigate these choices by assessing:
- Habits: Do you need water just for washing up, or for back-to-back showers?
- Existing Setup: How will the new heater integrate with your current boat plumbing services?
- Space Constraints: We specialise in finding a tiny footprint for even the most restricted galleys.
Integration and Galley Efficiency
A high-performance water heater is just one part of a comfortable onboard home. To maximise your efficiency, many boaters pair their water system with a modern cooker. If you are planning a full galley overhaul, read our guide on choosing an LPG cooker for your boat.
Signs Your Current Heater Needs Replacing
Knowing when to upgrade can prevent the dreaded “cold shower” moment. If you notice fluctuating water temperatures, unusual banging or popping noises, or visible rust on the unit, it is likely reaching the end of its life. Our engineers can provide an expert assessment to determine if a repair is possible or if a modern, safer unit is required.
