When you think about renovating your home in the UK – a new bathroom, a refreshed kitchen, maybe turning the box room into a cosy office – hot water doesn't always make the moodboard. But it should.
Swapping an old cylinder or tired system for a Camplux indoor gas water heater can quietly transform daily life: quicker showers, a tidier airing cupboard, and more efficient energy use. For many British homes, it's one of the smartest upgrades you can make during a renovation.
In this article we'll look at how Camplux gas water heaters fit into real indoor living in the UK, and how three key models – Camplux BY264, Camplux BD300-LP and Camplux BD300-NG – can slot into different types of homes and projects. We'll also cover installation basics, usage tips, and where to find the full indoor gas water heater range on.
Why Include Hot Water in Your Renovation Plan?
If you're already pulling up tiles or replacing cabinets, it's the perfect time to rethink how your home produces hot water.
Traditional tanks and older boilers can:
- Take up a lot of space
- Lose heat when you're not using hot water
- Struggle with pressure or flow in busy family homes
A modern indoor gas water heater tackles those issues by heating water only when you need it, in a compact unit fixed to the wall. That means:
-
No large cylinder dominating the cupboard
-
Instant hot water at the tap or shower
- A system that can suit everything from small flats to busy households
Camplux specialises in gas water heater solutions, with a dedicated indoor water heater collection designed specifically for kitchens, bathrooms and daily use around the home. The range is promoted as safe, efficient and reliable hot water for everyday living in British homes.
Meet the Three Heroes: BY264, BD300-LP and BD300-NG
Before we jump into planning, it helps to understand what each Camplux indoor gas water heater is best suited for.
Camplux BY264 – Compact LPG Solution for Smaller Spaces
Camplux BY264 indoor gas water heater (10 litres, LPG)
The BY264 is ideal if you:
- Live in a smaller terraced house or flat
-
Use LPG (butane or propane) rather than mains gas.
- Want to gain space by removing or downsizing an old cylinder
Key points for renovation planning:
-
Delivers 10 L/min of hot water, enough to feed a shower and a kitchen sink in lighter-use scenarios.
-
Works with butane or propane gas using the correct regulator (28–30 mbar for butane, 37 mbar for propane).
-
Uses 2 D-cell batteries for ignition, so doesn't need a 230 V electrical supply – useful for off-grid or older properties.
-
Has a 108 mm flue outlet and is designed for indoor installation in well-ventilated areas like a kitchen or balcony.
For a modest bathroom refurb or a rental flat upgrade, BY264 is often enough to give you consistent, instant hot water without over-specifying the system.
Camplux BD300-LP – LPG Power for Busy Households
Camplux BD300-LP 11L indoor LPG gas water heater
If your home is LPG-powered but has bigger demands – maybe two adults and kids, or frequent guests – BD300-LP is designed to keep up.
From the product specs:
-
Delivers up to 11 L/min of hot water – enough to supply two outlets, such as shower plus kitchen sink, at the same time.
-
Rated 22 kW with an energy class A label for water heating.
-
Works with propane or butane gas (same pressure ranges as BY264).
-
Uses an oxygen-free copper heat exchanger designed to heat water in about 5 seconds and resist bacterial growth.
-
Features ultra-low NOx emissions, aligning with modern low-emission expectations in the UK.
If your renovation brief includes “two showers in the morning without arguments”, an 11 L/min indoor gas water heater like BD300-LP makes planning easier.
Camplux BD300-NG – Natural Gas Comfort for Everyday Use
Camplux BD300-NG 11 L/min indoor natural gas water heater
For homes on the mains gas grid, BD300-NG offers a similar level of performance but tuned for natural gas rather than LPG.
According to the technical specification:
-
Provides 11 L/min hot water with a 22 kW nominal heat input.
-
Uses natural gas at 20 mbar, with water pressure as low as 0.25 bar to start – handy in older buildings or high-rise flats.
-
Rated A for water heating energy efficiency, helping with energy-conscious upgrades.
- Also features an ultra-low NOx design and oxygen-free heat exchanger for long-term reliability and cleaner hot water.
If you're replacing a dated gas system in a typical UK semi or terrace, BD300-NG gives you a compact, indoor gas water heater that slots neatly into modern renovation plans.
Step-by-Step: Planning a Camplux Indoor Gas Water Heater in Your Project
You don't have to be an engineer to plan where your gas water heater will go, but you do need a clear idea before the plasterboard goes up and tiles are laid. Here's a practical way to think about it.
1. Decide Which Outlets Need Instant Hot Water
Ask yourself:
-
Will this heater feed one bathroom, or bathroom plus kitchen?
-
Do you expect two people to shower back-to-back, or even at the same time?
-
Are you adding an ensuite, loft bathroom or utility sink?
For a single bathroom and light kitchen use, BY264 may be enough. For heavier use or two outlets at once, look at BD300-LP or BD300-NG, each designed to support two hot-water points.
2. Choose LPG or Natural Gas
-
If your property uses bottled gas (LPG), your shortlist is BY264 or BD300-LP.
-
If you're on mains natural gas, BD300-NG is the natural fit.
The gas type is fixed by your property, so it's usually an easy decision – but it has to be right.
3. Pick the Location with Your Installer
All three models are designed for indoor installation in well-ventilated positions, such as:
- Kitchens
- Utility rooms
- Suitable service cupboards or partially open balconies (where allowed).
Your Gas Safe engineer will confirm:
-
The best wall to mount the indoor gas water heater
-
How and where the flue will go outside (the units use a 108 mm exhaust outlet, with a typical flue length up to 3 m).
- Any clearance and ventilation requirements
4. Coordinate with Your Bathroom & Kitchen Layout
This is where renovation planning really pays off. Once you know the heater location, you can:
- Route hot-water pipework efficiently to showers, basins and sinks
- Hide pipe runs within stud walls where possible
-
Keep short runs to high-use fixtures (like the main shower), so hot water arrives quickly
Because a Camplux indoor gas water heater is relatively compact (around 550 × 325 × 214 mm for BD300 models), it's easier to tuck into tight spaces than a bulky cylinder.
5. Leave Access for Servicing
When you design cabinetry or boxing-in, make sure there's still:
- A removable access panel or service door
- Enough space for an engineer to get to the controls, pipework and flue connection
It's tempting to hide everything behind a perfect wall of doors – but your future self (and your Gas Safe engineer) will thank you for sensible access.
Living with a Camplux Indoor Gas Water Heater – A Typical Day
To see how this fits everyday British life, imagine a standard weekday in a semi-detached home using a Camplux indoor gas water heater:
7:00 am – Morning showers
The first person jumps into the shower. As soon as they turn on the hot tap, the gas water heater fires up, heating water on demand. No waiting for a tank to warm, no running water down the drain.
8:00 am – Breakfast & dishes
The shower's done, and now the kitchen needs hot water for washing up. A unit like BD300-LP or BD300-NG is designed to supply both bathroom and kitchen outlets at the same time, so you still get stable temperatures at the sink.
Midday – Work from home
Someone is working from home and uses hot water for cooking and hand-washing. The heater only fires when water is drawn, so you're not burning gas all day for a tank you're barely using.
Evening – Baths, showers and laundry
Later, the kids' baths and an extra shower put demand back on the system. With an 11 L/min indoor gas water heater, the home can handle these peaks more comfortably than a small cylinder might.
Throughout all of this, the unit quietly sits in a cupboard or on a utility-room wall, LED display ready, gas and water dials set to a comfortable temperature.
Safety & Legal Essentials in the UK
Gas work in the UK is regulated for good reason. Even though Camplux designs its indoor gas water heater models to be straightforward to use, installation and servicing must always be done by a Gas Safe registered engineer.
That includes:
- Gas pipework and connection
- Flue installation and termination
- Combustion checks and commissioning
- Any future adjustments or repairs
You can absolutely be involved in planning – choosing the model, location, and how it fits into your renovation – but the tools-on-gas side belongs to the professionals.
Quick FAQs for UK Homeowners
Q1: Can a Camplux indoor gas water heater replace my old cylinder?
In many cases, yes. A tankless gas water heater like BY264 or BD300 can provide on-demand hot water without a cylinder, freeing space and reducing standing heat losses. Always confirm suitability with your installer.
Q2: What about low water pressure?
BD300 models are designed to start from around 0.25 bar water pressure, which is helpful in older properties or flats with variable pressure.
Q3: Do I need electricity?
These indoor gas water heaters use battery ignition (2× D-cell) rather than a 230 V supply, which can be an advantage in certain installations or off-grid setups.
Q4: Are they efficient?
BD300-LP and BD300-NG carry A-class water heating energy efficiency labels, and all three models only heat water when it's actually being used, which can reduce wasted energy compared to keeping a tank hot.
