Unmatched Comfort With Your LPG Water Heater
Living on a narrowboat is about freedom and enjoying the UK’s incredible waterways. However, real comfort comes down to having reliable systems on board. Indeed, hot water is right at the top of that list.
Waiting for the engine to heat a calorifier is not practical most of the time. For instance, it is slow and inefficient. This is where a dedicated LPG water heater steps in and completely transforms daily life.
These modern heaters are built specifically for the marine world. Furthermore, they are compact and surprisingly efficient. They deliver hot water on demand for everything from washing up to a long, hot shower. As a result, it brings a level of convenience that truly feels like a luxury.

Why Choose a Professional LPG Water Heater Installation?
Getting the systems right on your narrowboat is a huge part of creating a comfortable home on the water. When it comes to hot water, your choice has a massive impact on your daily routine and fuel costs. For many boaters, an LPG water heater is a smart investment. In fact, it tackles the unique challenges of life afloat head-on.
The most obvious benefit is the sheer efficiency of these modern units. For example, older systems often need you to run a big, noisy engine just to get some hot water. An LPG water heater, on the other hand, only uses fuel at the exact moment you turn on the hot tap. This on-demand operation means you use far less gas, which directly lowers running costs.

This efficiency goes hand-in-hand with another must-have feature for any boat: a compact, space-saving design.
Maximum Comfort, Minimal Space: A Marine Heating Solutions Speciality
Space is the ultimate luxury on a narrowboat. Indeed, every single inch counts, and bulky appliances are not practical. The LPG water heaters we supply and install are chosen specifically for their tiny footprint. This lets us fit them neatly into cupboards or engine bays without eating into your precious living areas.
This clever design is a big part of why they are so popular. Specifically, you get all the performance of a much larger system without the physical bulk. It is all about making life on the water simpler and more pleasant.
Just picture it:
- Waking up on a chilly morning and having an instant hot shower, with no need to think about the engine.
- Washing up after dinner with a ready supply of hot water makes galley chores quick and painless.
- Enjoying the peace and quiet of your mooring, free from the noise of a rumbling engine, just for basic comforts.
This convenience isn’t just a small perk; it’s a genuine upgrade to your quality of life. Our expert team will ensure you get the right model for your boat’s layout, fitted perfectly by our qualified engineers.
The Rise of On-Demand Water Heating
The shift towards on-demand systems is part of a wider trend. More and more people across the UK are prioritising energy savings. Tankless LPG water heaters deliver a continuous supply of hot water. Moreover, they are much more efficient and take up less space. This makes them absolutely ideal for off-grid living, like on a canal boat, where LPG is already a common fuel.
Choosing an LPG water heater from our range means you are opting for reliability, efficiency, and comfort. It is a system that works with the rhythm of boat life, not against it.
Of course, making your whole galley efficient is key. That is why many boaters pair their new water heater with an equally reliable cooker. If you are thinking about a full galley overhaul, you might find our guide on choosing an LPG gas cooker for your boat helpful.
Finding the Perfect LPG Water Heater in Our Collection
Picking the right water heater is a big decision. In fact, it will affect your comfort for years to come. That is why we have put together a curated collection of LPG water heaters. Each one is personally vetted and trusted for life on the UK’s inland waterways.
We are here to guide you through the choices. We will ensure the model you end up with is genuinely the right one for your boat and how you use it.

Think of this as expert recommendations from people who have been there. Our team has spent years working on narrowboats and barges. Therefore, we know exactly what works and what does not. We have used that experience to stock only the most reliable and efficient units.
Selecting the Right LPG Water Heater for Your Needs
Every boater is different. For example, a weekend boater has different needs than a family living aboard full-time. Because of this, our first step is always to have a proper chat and understand your needs.
We will help you figure out what you need by looking at a few key things:
- Boat Size: A compact unit is a must for smaller boats. However, larger vessels might need a more powerful LPG water heater to keep up.
- Your Habits: Are you just after hot water for washing up? Or are you planning on multiple, back-to-back showers?
- Existing Setup: We will look at your current gas and plumbing systems. This ensures any new heater integrates smoothly.
Once we have a clear picture, we can point you towards the right model. For instance, a small narrowboat with limited space would be best served by a compact unit. Conversely, a residential barge with a family needs a higher-capacity model.
Our Recommended LPG Water Heater Models
The models we stock are all about performance and reliability. We are proud suppliers and installers of industry-leading heaters. These heaters have proven their worth out on the cut.
These units are well-known for their durability and consistent performance in a damp marine environment. First, they get water hot quickly and efficiently. Secondly, this saves you money on gas. It also gives you that on-demand hot water that makes boat life so much more comfortable. A good LPG water heater will always recover its hot water supply much faster than an electric version.
Our goal is not just to sell you a box. Instead, it’s to ensure you invest in a system that delivers reliable, hassle-free performance for years. We provide the full solution, from expert advice right through to certified installation.
Choosing an LPG water heater should not feel like a shot in the dark. When you work with us, you are tapping into decades of real, hands-on experience. We will help you sort through the options and find the perfect appliance.
And to top it off, our professional installation guarantees it will run safely right from day one. You can find out more about our process on our main boat LPG water heater installation page.
The Critical Importance of a Professional LPG Water Heater Installation
When you are dealing with gas appliances on a boat, safety is everything. An LPG water heater is a fantastic bit of kit for any narrowboat. However, fitting one is a job that should only ever be handled by a professional.
This is precisely why the work must be done by a Gas Safe registered engineer with specific marine experience. The rules for gas systems on inland waterway boats are incredibly strict. Our team is not just Gas Safe registered. In fact, we live and breathe the unique challenges of working in the compact world of a canal boat.
We understand the nuances of correct ventilation, secure pipework, and flue integrity. All these small details are absolutely critical to keeping you safe. Therefore, our meticulous approach guarantees every installation is fully compliant with UK marine regulations.
Our process puts a massive emphasis on thorough inspections and secure connections. We complete these checks before we even think about commissioning the system. Your safety is always the priority.
Our Commitment to Your Safety with Every LPG Water Heater
Our qualifications are your peace of mind. We bring years of hands-on experience working specifically on UK narrowboats and barges. Furthermore, every one of our engineers is certified and keeps up-to-date with the latest standards.
We do not just connect a few pipes. Instead, we engineer a complete, safe system from the ground up. This involves:
- A full assessment of your boat’s layout and any existing systems.
- Carefully routing gas lines to prevent any stress and abrasion damage.
- Thoroughly testing for leaks at every single joint and connection point.
- Commissioning the appliance to double-check its performance and all safety features.
After the installation, we give you a full handover. We walk you through how to operate your new LPG water heater. We also provide all the necessary paperwork and certificates. It is also worth remembering that a correctly installed system is a non-negotiable requirement for a valid boat safety certificate. You can learn more about why certification is so vital in our guide to the LPG gas safety certificate for boats.
Maintaining Your LPG Water Heater for Lasting Performance
Getting your new LPG water heater expertly installed is the first step. However, looking after it properly ensures it runs safely for years. It is all about protecting your investment with regular, professional maintenance. This not only guarantees lasting performance but also gives you complete peace of mind.
At Marine Heating Solutions, our job does not end when the installation is complete. Indeed, think of us as your long-term partner in keeping your boat’s systems in perfect working order. We offer comprehensive servicing to keep your appliance happy.

This ongoing care really is vital. An annual service by a qualified, Gas Safe registered engineer is the single most important thing you can do. In fact, it is absolutely essential for both safety and performance.
What Our Annual LPG Water Heater Service Includes
When you book a service with our team, you are getting more than just a quick check-up. Our engineers carry out a detailed inspection and tune-up. We have seen first-hand how regular servicing prevents the vast majority of common faults.
Our service process is thorough and covers all the bases:

Your LPG Water Heater Questions Answered
We get it – putting a new system into your narrowboat brings up a lot of questions. To help you out, we have put together some of the most common queries our team answers. Here are some clear, straight-to-the-point answers from our marine heating experts.
Our aim is to give you the confidence to make the right choice. That means transparent, genuinely helpful advice. As a result, you feel you’re in the loop every step of the way.
How Much Does a Professional Installation Cost?
This is usually the first thing boat owners ask. The honest answer is: it depends. The final price really comes down to two things. First is which specific LPG water heater you pick from our curated collection.
The second is how complex the job is on your particular boat. For instance, slotting a new heater into a boat with a modern, compliant gas system is different. It is a world away from a job that needs completely new pipework from scratch.
We believe in being upfront from the get-go. That’s why we always start with a detailed chat to assess your boat. After that, we will give you a bespoke, no-obligation quote. No hidden fees, just a clear price reflecting the value and safety you get.
What Are the Signs My Boat’s Water Heater Needs Replacing?
Knowing when to upgrade is the key to avoiding that dreaded moment when the hot water gives up. There are a few classic tell-tale signs that your current water heater is on its last legs. If you spot any of these, it is definitely time to give us a call.
Keep an eye out for these common symptoms:
- Fluctuating Water Temperatures: If your shower suddenly goes from hot to cold, your unit is probably struggling.
- Unusual Noises: Any banging, popping, or rumbling sounds often point to a component that is about to fail.
- Visible Rust and Corrosion: Obvious rust on the unit or rusty-coloured water are major red flags.
Our experienced engineers can pop over and give it an expert assessment. We will tell you straight whether a simple repair will do, or if a new LPG water heater is the smarter and safer move.
How Long Does a Typical Installation Take?
We know your time on the boat is precious. Therefore, we work efficiently to cause as little disruption as possible. A standard LPG water heater installation is a job we have got down to a fine art. We have worked on boats across the UK’s inland waterways for years.
In most cases, we can have the whole job done and dusted within a single day. Our team turns up fully prepared with the right appliance and all the necessary parts. This means you can be enjoying reliable, on-demand hot water by the evening. Consequently, your boat is in capable hands.
