Up to 1.58 GPM from a 41,000 BTU burner

That's the maximum flow the listing states, and headline flows are usually quoted at a mild temperature rise. At 2 GPM a shower (our calculator's figure), that's one person at a time: the kids, then the dog, then you.

What it has going for it

What changes at the campsite

Runs on a 20 lb tank. Screw it to the tank, hook up a garden hose and you have a hot rinse at the campsite, the barn or the beach house. Outdoors only: it burns propane right there with no vent.

From 3 PSI. The lowest water pressure it starts with, per the listing. Handy on an RV pump or a gravity tank.

Campsite or backyard shower?

At the campsite: it runs off a 20 lb tank, it starts from 3 PSI of water pressure and it weighs 13 lb, per the listing. That pressure is within reach of a 12 V RV pump.

In the backyard: a garden hose and a 20 lb tank are all it needs. Its spot is in the open air, out of the wind; a shed, a tent or a closed stall is out.

Great for you if…

You need one shower or one sink at a time, not the whole house
Camping, the RV or an outdoor shower is the plan

Skip it if…

You want something to mount inside the house: this one runs outdoors only
You'd rather wait for buyer reviews: none are captured for this listing yet
There's no outlet where you'll use it: the listing names no battery ignition

Fuel, water hookup and what's in the box

What the CAMPLUX BW158B Portable (1.58 GPM) listing names:

Up to 1.58 GPM
41,000 BTU/h input
Propane
Outdoor use only
Runs off a 20 lb tank
Starts from 3 PSI
13 lb

Read the installation manual for the vent, the gas line size and the clearances before you order; it overrides anything above.

Price and cost per GPM of stated flow

$169.99 Price on Sep 30, 2026 · may have changed

At the price on Sep 30, 2026, each GPM of stated maximum flow works out at about $107.59 (price ÷ stated GPM, our arithmetic). That puts it around the middle of the 7 portable propane water heaters we have a price and a stated flow for.

Count a 20 lb propane tank if you don't have one, and a hose to reach the water.

A better fit for your trips?

Want a stronger flow? The VELPAX 110,000 BTU Natural Gas Outdoor (7.0/10) states 4.76 GPM.

No outlet out there? The CAMPLUX 5L Portable Propane, 1.32 GPM (7.3/10) lights on batteries, per its listing.

Want the shower head in the box? The Amzgachfktch 1.58 GPM Portable Propane (7.3/10) comes with one, per its listing.

Our take

The verdict

The CAMPLUX BW158B Portable (1.58 GPM) earns its place with up to 1.58 GPM and a grab-and-go propane heater. No buyer reviews yet, so this CAMPLUX portable propane water heater has to win you over on paper. The catch with the CAMPLUX: no word on the warranty. We'd pick it if you need one shower or one sink at a time, not the whole house; otherwise, put it next to the VELPAX 110,000 BTU Natural Gas Outdoor first.

Living with it

Setup

Tank, regulator, garden hose: that is the whole install. Pick a spot in the open air, out of the wind.

The first rinse

Open the water, let the burner light, then set the temperature. It needs at least 3 PSI to start, per the listing.

Between trips

Drain it, disconnect the tank, and store it dry. A unit left full in a cold shed can crack.

The one thing we'd check first

Before you order the CAMPLUX BW158B Portable (1.58 GPM), check your water pressure: it needs at least 3 PSI to fire up, so check your pump or your hose bib.

Before you buy

Water pressure

It starts from 3 PSI, per the listing. A garden hose off a house tap is usually plenty; an RV pump or a gravity tank is worth checking first.

The tank and the hose

It is made for a 20 lb tank. Check that the regulator and the gas hose come in the box, and keep a spare tank for a long weekend.

Where it runs

Outdoors only, with open air around it. Never in a tent, a camper, a garage or a closed shower stall: it burns propane right there and makes carbon monoxide.

Before the frost

Drain it after the last trip of the season. Water left inside can freeze and crack the heat exchanger. Our natural gas vs propane guide covers propane setups.

Frequently asked questions

Is the CAMPLUX BW158B Portable (1.58 GPM) any good?

We rate it 6.6/10 (good). The rating comes from its documented listing alone, as no customer-review record is captured yet.

How much hot water can the CAMPLUX BW158B Portable, 1.58 GPM deliver?

The listing states a maximum flow of 1.58 GPM and a gas input of 41,000 BTU/h. The headline flow is a mild-weather number: with cold winter water coming in, the same unit gives you less. Read the maker's flow chart at your winter rise, or let our flow-rate calculator do the sums.

Can the CAMPLUX BW158B Portable, 1.58 GPM be installed indoors?

No. It is a portable propane unit with no vent connection, so it belongs outdoors with air all round: never in a closed room, a tent or a vehicle.

What do you get with the CAMPLUX BW158B Portable (1.58 GPM)?

Its listing states up to 1.58 GPM and hot water from a 20 lb propane tank. These are the seller's figures, not our measurements: how steady the temperature is in your shower and how it copes with your winter water can't be read from a listing.

What should I check before ordering the CAMPLUX BW158B Portable (1.58 GPM)?

Water pressure: it starts from 3 PSI, per the listing. A garden hose off a house tap is usually plenty; an RV pump or a gravity tank is worth checking first.

Where it runs: outdoors only, with open air around it. Never in a tent, a camper, a garage or a closed shower stall: it burns propane right there and makes carbon monoxide. Before the frost: drain it after the last trip of the season. Water left inside can freeze and crack the heat exchanger. Our natural gas vs propane guide covers propane setups.
