Best gas water heater

Updated: 17.10.2026

The best gas water heater in this amazon.co.uk set depends on the job. One winner for every room does not exist. Outdoor cylinder showers carry the long review counts. A bathroom needs a room-sealed flue and a Gas Safe engineer, which those camping listings do not provide. This page names an outdoor top pick, a smaller best-value alternative, where a pump changes the choice, and the indoor candidate with a balanced flue. Prices and stars are the amazon.co.uk figures from 15 October 2026. There is no lab test. The full table is the [gas water heater comparison](/hub/hot-water/gas-water-heater). A qualifying purchase through the links can earn a commission at no extra cost to you.

Best outdoor pick in this set

For a garden, stable, or hose shower in free air, the outdoor top pick is the Camplux BW264BC: 4.4 from 519 reviews, about £289.99, 10 litres a minute, 20 kW, and a rain cap. Camplux’s UK page says a 37 mbar propane regulator. That record is customers, not a lab. Wind still blows the flame out. The specification field says Natural Gas, while the bullets describe propane. If you opened the listing for that line, leave it. Skip it indoors. The bathroom rule is on the buying guide.

A smaller outdoor alternative

Choose the Camplux AY132B when 5 litres a minute is enough and about £150 is the budget. It is the best value in this set: about £150.44, 4.1 from 201 reviews, 10 kW, 4.54 kg, and a 37 mbar propane regulator in the box. Two D batteries are not included. Five litres a minute at 10 kW is a mild-weather rinse once the inlet is cold. If you want 10 litres a minute, the BW264BC stays the outdoor top pick. The Gearpass outdoor unit at £74.13 is 3.4 from 19 reviews, with no named 37 mbar figure.

When a pump changes the pick

A pump changes the pick only when the supply cannot start the heater. A garden tap often reaches 0.25 bar. A butt or a weak caravan feed often does not. The AY132B and the BW264BC do not include a pump. The Gasland G10 Pro is the stronger pump listing if you still want about 10 litres a minute: about £199.99, 4.0 from 328 reviews, 20 kW, with 37 mbar propane and 28–30 mbar butane named. A pump does not add heat. The BE158BP60 has more reviews and a 12 V pump, but it prints 37 kW beside 6 litres a minute, and one pump arrived dead.

Indoor natural gas in this set

The indoor candidate is the Camplux GX318NG, and only for a Gas Safe install: 12 litres a minute, 24 kW, a 60/100 mm balanced flue, about £179.99, and 4.2 from 129 reviews. The bullets state natural gas at 20 mbar. That figure is not a UK commissioning result, and the flue kit is not in the box. Written reviews mix other models. Do not use the Gearpass JSQ32 as a bathroom answer. Its 2.36 inch vent is not room-sealed. Do not use the BD300NG either: the bullets say balcony or kitchen and a 108 mm exhaust, while the title also says bathroom. The BFCMA gas flue guide says open-flued gas appliances are not for bathrooms, showers, or garages. Propane versus the meter is the LPG or natural gas page. Where a camping burner may stand is the portable gas shower page.

Common questions

Which outdoor unit has the strongest review count that is actually its own?
The BW264BC, at 4.4 from 519 amazon.co.uk reviews. The BW158BC shows 4.4 from 518, but the written texts match the BW264BC file. The BE158BP60 has 798 reviews and prints both 37 kW and 6 litres a minute, so the listing is not coherent. For an outdoor 10 litre hose shower, 519 reviews on the BW264BC is the count this page uses.
Who should buy the 5 litre AY132B instead?
Buy it when a short outdoor rinse is the job and about £150.44 is the budget. You get a 37 mbar propane regulator in a 4.54 kg unit, with 201 reviews behind horse and garden use. Move to the BW264BC for 10 litres a minute and 20 kW, and check the data plate, because the specification field still says Natural Gas.
Does the BE158BP60 pump make it the low-pressure pick?
It makes the BE158BP60 a candidate, and the pump reviews stop it being the pick. One buyer found the included pump dead. The G10 Pro is the low-pressure listing this page prefers when you still want 10 litres a minute, at about £199.99, with both UK LPG pressures named. Very cold stream water stayed too cool in a G10 Pro review. A pump fixes weak pressure. It does not replace kilowatts.
Which indoor listing describes a balanced flue?
The GX318NG. The bullets describe a 60/100 mm balanced flue, 12 litres a minute, and 24 kW, at about £179.99. The flue kit is not in the box, and 20 mbar on the page is not a commissioning certificate. A Gas Safe engineer has to accept the appliance, the flue route, and the meter pressure. The BD300NG’s 108 mm exhaust is an open arrangement, with balcony or kitchen in the bullets.
Who should skip both Gearpass units?
Skip them if you need a UK propane regulator in the box, a room-sealed bathroom flue, or a review file large enough to judge a gas appliance. The outdoor Gearpass is £74.13 with 3.4 from 19 reviews, and a reducer that does not fit European bottles in the sample. The JSQ32 is about £159.99 with 3.5 from 15 reviews and a short vent that is not room-sealed. A garden trial is the only use those reviews support.
Is best a lab result?
No. Products Compared did not heat these units on a test rig. Best outdoor here means the BW264BC’s own 519 reviews plus a 10 litre, 20 kW listing that matches the maker’s UK page, with the natural-gas field called out. Best value means the AY132B’s complete kit at about £150.44. A weak supply points at the G10 Pro. A mains-gas kitchen points at the GX318NG.
