If you live in a UK flat, a cosy terraced house or a converted loft, you probably know the struggle: limited cupboard space, rising energy bills and a hot-water system that feels older than the building itself.
That's where a Camplux indoor gas water heater comes into its own. Compact, efficient and designed for real indoor living, it gives you instant hot water without a bulky cylinder – perfect for modern small-space homes.
In this article we'll look at how Camplux fits everyday British life, especially in smaller properties, and how three key models – Camplux BY264, Camplux BD300-LP and Camplux BD300-NG – can be matched to your gas supply and layout. We'll also cover installation basics, day-to-day use and how to choose the right indoor gas water heater for your home.

1. Why Small UK Homes Need Smarter Hot Water
Many UK homes still rely on traditional hot-water cylinders or aging systems that:
- Take up half the airing cupboard
- Lose heat all day, even when nobody's using hot water
- Struggle to cope when more than one tap or shower is running
A modern indoor gas water heater works differently. It's a tankless gas water heater that:
- Mounts neatly on the wall
- Heats water only when you open a tap or shower
- Delivers hot water within a few seconds, so you waste less time and less water
Camplux's indoor range is designed specifically for this on-demand approach – bringing hot water to UK bathrooms and kitchens in compact units sized for flats, terraces and family homes.

In this guide we'll focus on three core models loved by UK households:

Camplux BY264 – 10L LPG indoor gas water heater
-
Camplux BD300-LP – 11L LPG indoor gas water heater with low NOx emissions
-
Camplux BD300-NG – 11L natural gas indoor gas water heater
Each is designed for indoor use and can supply more than one hot-water point when sized and installed correctly.
3. Camplux BY264 – Compact Choice for Flats, Studios & Annexes
Product link:
👉 Camplux BY264 Indoor Gas Water Heater, 10 Litres LPG
The Camplux BY264 is an LPG indoor gas water heater that's especially suited to small properties and off-grid living. From the product description, it:
-
Supplies around 10 litres of hot water per minute, enough for a comfortable shower and kitchen sink in lighter-demand homes.
-
Works with both butane and propane gas, as long as the correct regulator pressure is used.
-
Uses two D-cell batteries for ignition, so it doesn't rely on a 230 V mains socket – helpful in older or rural properties.
Where BY264 Fits Best in UK Indoor Life
-
City flats & studios – Mount it in a kitchen or utility corner to cover a single bathroom and sink.
-
Annexes & garden rooms – Ideal for a self-contained annex that needs its own hot water.
-
LPG or off-grid homes – Because it runs on butane/propane and uses battery ignition, it suits rural cabins, static caravans or tiny houses when installed indoors with proper flueing.
If your home is compact, you live alone or as a couple, and you mainly want reliable hot water for one shower and your kitchen, BY264 is often the sweet spot.
4. Camplux BD300-LP – LPG Power for Busy Small Families
Product link:
👉 Camplux BD300-LP 11 Litres Indoor LPG Gas Water Heater
For households that use LPG but need more hot water – perhaps a young family or a couple who often have guests – the BD300-LP offers extra flow and performance.
According to the product page, this indoor gas water heater:
-
Delivers around 11 litres per minute of hot water, fast enough to serve two points at once (for example, a shower and a kitchen tap).
- Reaches working temperature in only a few seconds thanks to a high-efficiency copper heat exchanger.
-
Uses a low NOx burner design and is described as compliant with ErP standards for emissions and water heating efficiency.
Where BD300-LP Shines Indoors
-
LPG-powered terraced houses – One compact gas water heater can cover bathroom and kitchen.
-
Small family homes – Great when more than one person needs hot water in the morning.
-
Rural homes on bottled gas – You get a powerful, fixed indoor solution rather than relying on multiple small electric heaters.
If your renovation or upgrade involves an LPG system and you're worried about whether a tankless indoor gas water heater can keep up, BD300-LP is designed precisely for that “two outlets at once” scenario.
5. Camplux BD300-NG – Natural Gas for Everyday UK Homes
Product link:
👉 Camplux BD300-NG 11 L/min Indoor Natural Gas Water Heater
If your home is on the mains gas grid, the BD300-NG provides similar performance to the LPG version, but tuned for natural gas.
From the UK product listing, BD300-NG:
-
Produces up to 11 L/min of hot water and is advertised as suitable for two water points, such as bathroom and kitchen.
-
Uses an oxygen-free copper heat exchanger to deliver stable, efficient heating performance.
-
Is described as a low NOx / ErP indoor gas water heater, aligning with modern European efficiency and emission requirements.
Everyday Use in British Indoor Life
-
Standard semis and terraces – Mount it in a kitchen, utility space or service cupboard and feed the main bathroom plus kitchen sink.
-
Older properties upgrading from cylinders – Free up the airing cupboard by replacing a storage tank with this wall-mounted gas water heater.
-
Working-from-home households – Because it heats only on demand, you're not keeping a cylinder hot all day for just a few cups of tea and hand-washes.
6. Installation & Safety: Non-Negotiables for UK Homes
No matter which Camplux indoor gas water heater you choose – BY264, BD300-LP or BD300-NG – a few core rules apply in the UK:
a.Gas Safe installation only All gas work, including connection, commissioning and future servicing, must be carried out by a Gas Safe registered engineer.
b.Correct gas type & pressure BY264 and BD300-LP are for LPG and are specified for use with butane and propane within particular pressure ranges.
c.BD300-NG uses mains natural gas at the pressure indicated in the technical data.
d.Proper flueing & ventilation These are indoor units and must be installed with a suitable flue system to safely expel combustion gases. The product pages show they are intended for indoor use with external venting.
e.Location & clearances Typical positions include kitchens, utility rooms or service cupboards with appropriate clearances, access and flue routes.
f.Once installed correctly, daily operation is simple: select your preferred temperature on the front panel, open the hot tap, and the gas water heater starts automatically.
7. Everyday Indoor Scenarios: How It Actually Feels
To picture a Camplux indoor gas water heater in your small UK home, imagine these typical moments:
Morning in a One-Bed Flat (BY264)
You roll out of bed in a one-bed flat and head straight for the shower. As soon as you turn on the hot tap, the BY264 fires, powered by LPG and battery ignition. In a few seconds you have a steady, comfortable flow – no waiting for a cylinder to recover, no “someone used all the hot water” drama.
Sunday in a Small Family Home (BD300-LP or BD300-NG)
Parents are cooking Sunday lunch while a teenager grabs a shower upstairs. With an 11L indoor gas water heater, there's enough flow for both kitchen tap and shower so everyone carries on without sudden temperature swings.
Work-From-Home Day
Most of the day you only need hot water in short bursts – hands, mugs, a bit of washing up. Because Camplux heats on demand, your gas water heater isn't burning gas all day just to keep a large tank at temperature. This is exactly the benefit of tankless indoor systems highlighted in Camplux's wider gas tankless range.
8. How to Choose: A Simple Checklist
When you're comparing BY264, BD300-LP and BD300-NG, use this quick checklist:
a.What gas supply do you have? LPG (bottled gas) → BY264 or BD300-LP
b.Natural gas (mains) → BD300-NG
c.How many outlets will run at once? Mostly one shower or one tap at a time → BY264 may be enough.
d.Often shower + kitchen or two taps → aim for the 11L BD300 models.
e.How much indoor space do you have? All three models are compact wall-mounted units, freeing cupboard space previously taken by a tank. Camplux highlights this space-saving design across its indoor range.
f.Do you want lower emissions and good efficiency? BD300-LP and BD300-NG are described as low NOx / ErP water heaters with A-class efficiency ratings for water heating.
Discuss your answers with a Gas Safe engineer and they can confirm sizing, positioning and flue options based on your specific property.
