A portable propane tankless water heater gives you a hot shower or a warm rinse for pets without a storage tank. It is handy for campers, cabin owners and anyone without reliable hot water. Two things matter most: water pressure, because some units need more pressure to start, and heat output, because low output makes a cold-weather shower feel weak.
Our top pick is the GASLAND BE158B, which pairs 41,000 BTU and 1.58 GPM with a digital temperature readout. The Camplux AY132 is the lightest option for solo campers, and the Syfuulv suits cold weather. Here is what's available right now, from the lowest price to the lowest start pressure.

One catchIt needs at least 3.6 PSI of water pressure to start, a little more than the 3.0 PSI budget models on this list.
Why it's our top pick
The BE158B puts the most useful features in one unit: 1.58 GPM of flow, 41,000 BTU of heat and a digital temperature readout. One expert review named it the best value pick and pointed to its real digital display as the reason. It runs on a standard 20 lb propane tank, with two D-cell batteries for ignition, and the maker says it suits camping, washing pets and cleaning a vehicle.
Check that your water supply reaches 3.6 PSI before you buy. The package includes a 5-foot on/off shower head, a CSA certified gas regulator and hose, so you can connect it without extra parts.
2Lightest pick

- Lightest of the picks at 10 lb, with a folding handle
- Starts at 3.0 PSI, good for gravity bags and small pumps
- Recommended by both expert reviews
- CSA approved with 6-in-1 protection
Cons
- 1.32 GPM is less flow than the picks above; one reviewer said it is enough unless you have an unlimited water source nearby
- One reviewer found the included hose too short and suggests an 11-foot shower hose
Read our full take
Why we like it
This is the model both expert reviews recommend. It runs on a 20 lb propane tank and two D-size batteries, and at 10 lb it is easy to carry from the car to a campsite. Its 1.32 GPM flow is enough for one person, according to one reviewer, who said it is plenty unless you have an unlimited water source nearby.
Check that the listing you buy includes a stand. One reviewer had to build one, and the same reviewer found the 6-foot hose too short.
3Best for cold weather
Syfuulv PD41 Propane Tankless Water Heater, 1.58 GPM, 41,000 BTU
A 1.58 GPM heater with a winter setting, for cold-weather camping and shoulder-season trips.
- Heat output
- 41,000 BTU

- 1.58 GPM (6L)
- Start pressure
- 3 PSI
- Efficiency

- Cold weather

Prices and availability on Amazon change often.
Pros
- 41,000 BTU and 1.58 GPM for full-flow hot water
- Winter mode is listed to hold output steady in cold air
- Oxygen-depletion shutoff, overheat protection and high-pressure auto-drainage
- Starts at 3 PSI
Cons
- The water pump is not included and must be bought separately
- The efficiency and runtime figures are manufacturer claims, not independent results
Read our full take
Why it's our cold-weather pick
The Syfuulv has the same 41,000 BTU and 1.58 GPM output as the top pick, plus a winter mode that the maker says keeps output steady in cold air. Its outdoor setup includes a 5-foot propane hose with regulator, an oxygen-depletion shutoff and automatic drainage at high pressure.
The listing also claims 89% thermal efficiency and that one 20 lb tank lasts over 15 hours. These are the manufacturer's figures, so treat them as a guide rather than a promise.

- Brass connector, which the maker says is built to last
Cons

Read our full take
Why it's worth a look
This Kohree costs less than the other picks while listing the same 41,000 BTU and 1.58 GPM output. The gas pipe comes pre-connected, which removes one connection from setup, and the maker says the heater can be used on windy days.
The maker advises the 6L model where the average winter temperature stays above 50 degrees F, and a larger 10L model below that. Check your local winter minimum before you buy.
5Lowest start pressure

Cons

- The listing warns that prolonged rain exposure damages internal parts, so store it dry
Read our full take
Why it's our low-pressure pick
If your water supply is weak, start pressure matters more than the BTU number. This model starts at 2.5 PSI, the lowest on the shortlist, and delivers 40,000 BTU and 1.58 GPM once it is running. The package covers the shower head, gas regulator, hose adapter and mounting hardware.
Check your water pressure before you buy. the maker says a booster pump is recommended for low-pressure homes, and it says not to use Teflon tape on the gas regulator joint.
FAQ
Which pick suits you?
Solo campers and small showers will do well with the lightest pick, which weighs 10 lb and starts on low pressure. Families or anyone who wants a full-flow shower should look at the top pick, with 1.58 GPM and a digital display.
Cold-weather trips call for the Syfuulv and its winter mode. Buyers on a tight budget can start with the Kohree, and anyone with a weak water supply should check the 2.5 PSI model.
What to check before you buy?
- Water pressure: confirm your supply reaches the unit's start pressure, from 2.5 to 3.6 PSI on these models.
- Heat output: 40,000 BTU or more keeps showers hot when the air is cold.
- Hose length: one reviewer found the included hose too short and suggests an 11-foot hose.
- Certification: one expert review advises checking for CSA or ETL certification on any propane portable water heater.
- Display: a digital readout makes it easier to judge the temperature, which one expert review says matters with children.
When a portable heater is not the right fit?
If your water supply cannot reach the start pressure of the model you choose, the heater will not light, so plan a 12-volt pump first. The water pump is not included with some models, so add its cost to your budget.
A portable heater suits one or two showers at a time. For a larger household, a fixed unit is a better choice.
How long will a 20lb propane tank last on a tankless water heater?
Run time depends on how much hot water you draw and how cold the water is. The only runtime figure on these listings is a manufacturer claim that one 20 lb tank lasts over 15 hours on the Syfuulv. Plan for a shorter run if you shower often in cold weather.
What are some good portable tankless water heaters for camping?
The GASLAND BE158B is our top pick, with 1.58 GPM and a digital display. The CAMPLUX AY132 is the lightest option at 10 lb, and both expert reviews recommend it. For cold weather, the Syfuulv has a winter mode, and the Kohree is the lowest-priced pick on this list.
Who makes the best propane tankless water heater?
No single brand leads every category on this list. Our top pick is made by GASLAND, while Camplux, Syfuulv, Kohree and Amzgachfktch each win on a specific need such as weight, cold weather, price or low start pressure. Choose by your water pressure and climate first, then compare the brand.
