The best portable camp water heater in NZ overall is the Maxkon 9-in-1 Gas Hot Water Heater, because it bundles a built-in water pump with the burner, shower head and gas hose, so campers get a hot shower even where there is no tap pressure or mains power. Portable camp water heaters are compact LPG califonts that heat water on demand as it flows through a copper heat exchanger, giving a warm shower, a full sink or clean dishes at a campsite, bach, boat or building site. This guide compares six units sold in New Zealand, each with a clear Best for angle so shoppers can match a heater to how they actually camp.
All six run off a standard LPG bottle and most use two D-cell batteries to fire the ignition, so no generator is needed. They pair well with the rest of a campsite kit, whether that is portable solar panels to keep devices charged or a reliable headlamp for after-dark rinses. Testers weighed flow rate, whether a pump is included, safety cut-outs, weight and how fiddly each was to set up.

1. Maxkon 9-in-1 Gas Hot Water Heater – Best Overall
The Maxkon 9-in-1 is the best all-round portable camp water heater in NZ because it is a complete, pump-equipped shower kit that works even with no tap pressure. Where the cheaper units expect a pressurised water source, this black tankless model ships with its own water pump, so it can draw straight from a bucket, jerry can or stream and still push a steady 10 litres a minute through the shower head. The nine-piece bundle covers the heater, gas hose and regulator, shower head and hose, the pump, and mounting hardware, which is why testers reach for it first for genuine off-grid trips.
Physically it is the bulkiest of the group once the pump is packed, and the housing is a matte black steel and plastic shell with a fold-down carry handle and two rotary control dials for gas and water. Ignition runs off two D-cell batteries, so it lights instantly without mains power. Owners of the Maxkon range note the dials are plastic and that reaching the top advertised temperature means dropping the flow right down, which is the main trade-off against its flexibility.
Pros
- Built-in pump means true off-grid use without tap pressure
- Complete 9-piece kit, nothing extra needed but gas and batteries
- Strong 10 L/min flow suits family showers and dishes
Cons
- Bulkiest and heaviest option once the pump is included
- Plastic control dials and top temperature needs low flow
Key specs: ULPG gas, 10 L/min, tankless instant heating, includes 12V water pump, 2 x D-cell ignition, black finish. Model PID 100328.
2. Devanti Portable Gas Hot Water Heater – Best for Easy First-Time Setup
The Devanti grey gas water heater is the easiest pick for anyone buying their first camp califont, thanks to a clear LED screen and plug-and-play safety features. It heats up to around 480 litres an hour, roughly 8 litres a minute, and shows the live water temperature on a front LED display rather than leaving campers guessing on a dial. A built-in processor caps the water at about 60 degrees to guard against scalding, and separate winter and summer settings plus a water-flow adjuster make it simple to dial in a comfortable shower in changing conditions.
The grey polymer body has a moulded carry handle and comes with mounting brackets, a variable-flow shower head with an automatic on and off trigger, a gas hose and regulator. Safety cover is generous for the price, with dry-burning protection, flame-out protection and incline-resistant protection that shuts the unit down if it tips. The catch is that this version has no pump, so it needs a pressurised water source, the two D-cell batteries are not included, and some assembly is required out of the box.
Pros
- LED temperature display is beginner friendly
- Winter and summer modes plus flow adjustment
- Triple safety cut-outs including tip-over protection
Cons
- No pump, so a pressurised water feed is needed
- Batteries not included and light assembly required
Key specs: LPG gas, up to 8 L/min (about 480 L/hr), LED display, max 60C, winter and summer settings, 2 x D-cell, grey finish. Model PID 51956.
3. Maxkon 7-in-1 Gas Water Heater – Best Budget Pick
The Maxkon 7-in-1 is the best budget portable camp water heater in NZ, giving the same 10 litre a minute flow as the flagship for less by leaving out the pump. It is the pared-back version of the Maxkon range in a silver finish, bundling the heater, gas hose and regulator, shower head and hose and mounting hardware across seven pieces. For campers at a powered site, a bach with mains pressure or anyone happy to add gravity from a raised tank, it delivers a full-strength hot shower at the lowest entry price here.
The silver steel casing keeps the same twin-dial layout and D-cell ignition as its siblings, so lighting is instant and controls are familiar. Because there is no pump, it relies entirely on incoming water pressure, and owners across the Maxkon line report that hitting a hot 38 to 40 degrees can mean turning the flow down and the gas up. The supplied hoses suit standard fittings, so a garden-hose adaptor is worth checking before a trip.
Pros
- Lowest price for a full 10 L/min flow
- Compact and lighter without the pump
- Instant D-cell ignition, no mains power needed
Cons
- Requires an existing pressurised water source
- Reaching hot temperatures can need low flow
Key specs: ULPG gas, 10 L/min, tankless, 7-piece kit, no pump, 2 x D-cell ignition, silver finish. Model PID 73989.
4. Maxkon Digital Instant Gas Water Heater – Best for Caravans and RVs
The Maxkon digital model is the pick for caravan and motorhome owners who want precise temperature control from a compact tankless unit. Rated at 520 litres an hour, roughly 8.7 litres a minute, it swaps the usual rotary guesswork for a digital control panel with a temperature display, so a set shower temperature can be repeated night after night. It is the newest release in this line-up and is pitched squarely at RV, caravan and boat fit-outs where a tidy mounted panel matters.
The body is more compact than the 10 litre Maxkon kits, which helps in a cramped van locker, and it still runs on an LPG bottle with D-cell ignition for off-grid starts. The digital readout is the standout feature and the reason it earns the caravan slot rather than the raw-flow models. Trade-offs are that the 520 L/hr flow sits just under the 10 L/min units for very long showers, the electronics lean on the batteries staying fresh, and like the others it expects a pressurised water feed rather than including a pump.
Pros
- Digital control display for repeatable set temperatures
- Compact footprint suits caravan and RV mounting
- Newest model in the Maxkon range
Cons
- Flow slightly lower than the 10 L/min kits
- No pump included, needs a water pressure source
Key specs: LPG gas, 520 L/hr (about 8.7 L/min), tankless, digital control display, D-cell ignition, for caravan and RV use. Model PID 104652.
5. Midea Portable Gas Water Heater – Best Compact & Lightweight
The Midea instantaneous califont is the best choice where light weight and a quality heat exchanger matter more than raw flow. At 6.0 kg net and just 413 by 310 by 136 mm, it is the smallest and lightest unit here, easy to lift into a car boot or onto a caravan wall. Inside sits an oxygen-free copper heat exchanger, a step up in materials from the budget steel coils, and a Multi-Point Showersafe system for safer operation. A low water-pressure start from 0.03 MPa means it fires even on gentle gravity or tank feeds where bigger units stall.
It is a 4 litre-per-minute class heater delivering about 3.5 kg of hot water a minute at a 25-degree rise, with a 28 MJ/h rated heat input, outlet-mounted controls and water-controlled automatic pulse ignition. That flow is the honest trade-off: it is ideal for one person rinsing off, washing up or a bach basin, but slower to fill a tub or run back-to-back family showers than the 10 litre Maxkon kits. It carries a one-year warranty. Campers pairing it with clean drinking water should also look at good water filters for the trip.
Pros
- Lightest and most compact unit at 6.0 kg
- Oxygen-free copper heat exchanger for durability
- Starts on very low water pressure from 0.03 MPa
Cons
- Lower 4 L/min class flow than the big Maxkon kits
- Only a one-year warranty
Key specs: ULPG gas, 4 L capacity class, oxygen-free copper heat exchanger, 28 MJ/h, 3.5 kg/min at 25K rise, 413 x 310 x 136 mm, 6.0 kg, 1-year warranty. Model JSZ8-4DZ.
6. Portable LPG Gas Water Heater (Black) – Best for Rugged All-Weather Use
This black portable LPG heater is the toughest pick for exposed, all-weather camping, thanks to a removable rain shield and tip-over protection. A removable rain shield panel sits over the burner so it keeps running in a drizzle at the beach or a wet bush site, and incline-resistant protection cuts the gas if the unit is knocked off level. It shares the proven Devanti-style layout with an LED digital display, adjustable temperature capped at 60 degrees, and dedicated winter and summer settings for year-round use.
Measuring 30.5 by 12 by 47 cm, it comes as a full kit with a variable-flow shower head and automatic on and off trigger, gas hose, regulator, water connector and mounting accessories. The 28 MJ/h burner delivers up to about 8 litres a minute and it runs on two D-cell batteries for ignition. It needs a minimum 0.3 MPa water pressure, so a pump or mains feed is required rather than a trickle, the batteries are not included, and assembly is needed before the first use. It ships with a one-year warranty. It slots in well alongside camp comforts like a good air mattress and packs down small enough to carry with the beach tents for a weekend away.
Pros
- Removable rain shield for wet-weather use
- Incline-resistant, dry-burn and flame-out protection
- Full kit with LED display and auto-trigger shower head
Cons
- Needs 0.3 MPa minimum water pressure, no pump included
- Batteries not included and assembly required
Key specs: LPG gas, 28 MJ/h, up to 8 L/min, LED display, max 60C, winter and summer settings, removable rain shield, 30.5 x 12 x 47 cm, 2 x D-cell, 1-year warranty, black finish.
How to Choose a Portable Camp Water Heater
Pump or no pump. If there is no tap or tank pressure at the campsite, choose a unit with a built-in pump such as the Maxkon 9-in-1. If a bach, powered site or gravity tank supplies pressure, a pump-free model saves money and weight.
Flow rate. A 10 L/min unit fills sinks and runs family showers faster, while a 4 L/min class califont like the Midea is lighter and fine for solo rinses and dishes.
Power and gas. Most models light from two D-cell batteries and run off a standard LPG bottle, so no generator is needed. Keep spare batteries and check the regulator fits NZ gas bottles.
Safety. Look for flame-out protection, dry-burn protection and a temperature cap. Tip-over or incline protection matters on uneven ground, and these heaters must only be used outdoors in open air.
Weight and mounting. Caravanners benefit from a compact digital unit that mounts neatly, while hikers and beach campers value the lightest body and a carry handle. Pair the heater with the rest of the kit, from a headlamp to sturdy hiking boots, for a complete setup.
Verdict
For most New Zealand campers the Maxkon 9-in-1 Gas Hot Water Heater is the best portable camp water heater overall, because its built-in pump and complete kit deliver a hot shower anywhere, on or off the grid. First-time buyers who camp at powered sites will find the Devanti the easiest to live with, the Maxkon 7-in-1 is the value king, the Maxkon digital suits caravans, the Midea wins on weight, and the black rain-shield unit is built for foul-weather trips. Match the flow rate and pump choice to how you camp and any of these will keep the hot water coming.
FAQs
Do portable camp water heaters need electricity?
No mains power is needed. Most portable camp water heaters light using two D-cell batteries for ignition and run entirely off an LPG gas bottle. Some kits add a 12V water pump that can run from a battery or power bank, so the whole system works completely off-grid at a remote campsite.
How does a portable gas camping water heater work?
Cold water flows through a heat exchanger where an LPG burner heats it on demand, with no storage tank. Opening the shower head triggers the water flow, which fires the gas burner, and hot water comes through almost instantly. A dial or digital panel sets the temperature while it runs.
Are portable gas water heaters safe to use?
They are safe when used outdoors in open, well-ventilated air, never inside a tent, van or cabin, because gas burners produce carbon monoxide. Most units add flame-out, dry-burn and tip-over cut-outs plus a temperature cap. Always leak-test hose connections with soapy water before lighting.
What size gas bottle do I need for a camping water heater?
A standard refillable LPG cylinder, commonly a 9 kg bottle in New Zealand, suits these heaters and gives many showers per fill. A smaller bottle is fine for short trips. Gas use depends on how hot and how often the water runs, so a solo camper uses far less than a family.
Can you use a portable camp water heater without water pressure?
Only if it has a built-in pump. Pump-equipped units like the Maxkon 9-in-1 can draw from a bucket, tank or stream. Pump-free models need a pressurised source such as mains, a 12V pump or a raised gravity tank, and units like the Midea can start on very low pressure.
How hot does the water get?
Most portable camp water heaters cap the outlet around 50 to 60 degrees Celsius for safety. In practice the water temperature depends on the incoming water and the flow rate, so turning the flow down and the gas up produces a hotter shower. A built-in processor prevents scalding by limiting the maximum.
