Up to 6.4 GPM from a 150,000 BTU burner

That's the maximum flow the listing states, and headline flows are usually quoted at a mild temperature rise. With January water coming in at 42 °F and a 105 °F shower, the rise is 63 °F and the real flow is lower; the maker's flow chart has that number. Counting 2 GPM per shower, as our calculator does, that's one shower and a sink at a time, maybe two showers where the water comes in warm.

What it has going for it

What changes in the morning shower rush

Mounts outside. No vent pipe through the roof or the rim joist: it hangs on an outside wall and breathes on its own. The listing states freeze protection, which typically needs power at the wall to work.

±1 °F hold. The burner adjusts as the flow changes, so the shower stays where you set it when somebody opens the kitchen tap. On paper, at least: that is the seller's claim.

Mild winters or hard freezes?

Mild winters: the CAMPLUX 150,000 BTU Propane Outdoor goes on an outside wall, which saves the vent pipe and keeps the closet free.

Hard freezes: freeze protection is stated, and it runs on electricity. A long outage in January is when you drain it, before the heat exchanger splits.

Great for you if…

You run one shower and the kitchen tap at once, rarely more
There is no good vent route inside your house
A shower that suddenly runs cold drives you mad

Skip it if…

Your winters freeze hard and the outside wall has no power for freeze protection
You want the high-efficiency kind: the listing doesn't call it condensing
The far bathroom already waits a minute for hot water: no built-in recirculation is named

Gas, mounting and what's in the box

What the CAMPLUX 150,000 BTU Propane Outdoor listing names:

Up to 6.4 GPM
150,000 BTU/h input
Propane
Outdoor mounting
±1 °F temperature hold claimed
Freeze protection named
CSA, ETL or UL mark named

The installation manual has the last word on venting, gas line and clearances; your installer reads it before you order.

Price and cost per GPM of stated flow

$629.99 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 $98.44 (price ÷ stated GPM, our arithmetic). That puts it around the middle of the 32 outdoor tankless heaters we have a price and a stated flow for.

Outside mounting saves the vent pipe; the gas line, the water lines and a weatherproof outlet are still a separate bill.

A better fit for your house?

Two showers and the dishwasher at once? The APUS 190,000 BTU Propane Outdoor (6.9/10) states up to 8.1 GPM.

Hard freezes where you live? The Marey 170,000 BTU Propane Indoor (7.6/10) is an indoor unit, out of the frost.

Want the high-efficiency kind? The ThermoMate Condensing Propane (7.6/10) is a condensing unit rated 0.86 UEF, per its listing.

Our take

The verdict

Our favourite thing about the CAMPLUX 150,000 BTU Propane Outdoor is a 6.4 GPM maximum flow, closely followed by outdoor mounting that skips the flue. Only 76 buyers have rated it so far (4.3/5), so treat the score as an early read. Our main reservation: no word on the warranty. We'd pick it if you run one shower and the kitchen tap at once, rarely more; otherwise, put it next to the APUS 190,000 BTU Propane Outdoor first.

Living with it

Install day

It goes on an outside wall, with gas, water and power run to it. Plan the gas line for 150,000 BTU/h; a licensed pro handles it, and often a permit.

The first shower

Hot water arrives after the cold already in the pipes, then stays (within ±1 °F, per the listing). A trickle from a bathroom tap may not light the burner; open it a bit more.

The first winter

January water comes in colder, so the same unit gives fewer GPM. Stagger the showers if you sized it tight.

Once a year

Flush the heat exchanger with a pump and a descaler (the service valves make it an hour's job), and clear leaves and wasp nests from the cabinet vents. Our flushing and descaling guide has the checklist.

What buyers say

Buyers give it 4.3/5, a solid record, right on our ranked picks' 4.3 average. 76 reviews is still a modest pile, so a handful of new ones can move it.

Ranked picks' average: 4.3/5

The one thing we'd check first

Before the CAMPLUX 150,000 BTU Propane Outdoor ships, check your gas line: 150,000 BTU/h is a lot of gas at once, so ask your plumber whether the existing line can feed it.

Before you buy

Your winter flow

6.4 GPM is the headline. In a northern January the water comes in near 42 °F, so a 105 °F shower needs a 63 °F rise and the real flow drops. Our flow-rate calculator runs the numbers for your house.

The outside wall

Pick a wall away from windows and doors, with power for the controls and the freeze protection the listing mentions. Our indoor vs outdoor guide compares the two installs.

The warranty terms

Read what it requires: a licensed install, the gas type and regular flushing are the usual conditions.

Flushing

Hard water scales the heat exchanger. Service valves on the water lines turn the yearly flush into an hour with a bucket and a pump; our flushing and descaling guide shows the routine.

Frequently asked questions

Is the CAMPLUX 150,000 BTU Propane Outdoor any good?

We rate it 6.8/10 (good). It is based on 76 buyer reviews averaging 4.3/5 and the specifications stated in the listing.

How much hot water can the CAMPLUX 150,000 BTU Propane Outdoor deliver?

The listing states a maximum flow of 6.4 GPM and a gas input of 150,000 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 150,000 BTU Propane Outdoor be installed indoors?

The listing says outdoor mounting. It only goes inside if the maker lists that exact model for indoor use, with the venting it specifies; a licensed gas installer confirms the spot under your local code.

What do you get with the CAMPLUX 150,000 BTU Propane Outdoor?

Its listing states up to 6.4 GPM, outdoor mounting that skips the flue and temperature held within ±1 °F. 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 150,000 BTU Propane Outdoor?

Your winter flow: 6.4 GPM is the headline. In a northern January the water comes in near 42 °F, so a 105 °F shower needs a 63 °F rise and the real flow drops.
