Up to 5.2 GPM from a 130,000 BTU burner

That's the maximum flow the listing states, and headline flows are usually quoted at a mild temperature rise. A cold January asks for a 63 °F rise (42 °F in, 105 °F out), and at that rise every tankless gives less than its headline; the maker's chart says how much. Our calculator counts a shower at 2 GPM, so on paper 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: hang it outside and you skip the vent run through the rim joist and the combustion-air questions indoors.

Hard freezes: the listing names freeze protection, which needs power at the wall. Plan for the night the power goes out and the thermometer drops: draining it is the fallback.

Great for you if…

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 a long review record: only 2 buyer reviews so far
You want the high-efficiency kind: the listing doesn't call it condensing

What STPFFOT promises

The seller states, word for word, in the STPFFOT 130,000 BTU Propane Outdoor listing:

This propane tankless water heater is equipped with an advanced thermostat system for precise temperature control (temp fluctuation ±1°F).
The included controller (15ft wire) allows you to easily adjust the water temperature from indoors.

The seller's claims, quoted as written; we haven't measured any of it. The flow at your winter rise is in the maker's chart, not in the bullet points.

Price and cost per GPM of stated flow

$419.99 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 $80.77 (price ÷ stated GPM, our arithmetic). That puts it in the cheaper third of the 32 outdoor tankless heaters we have a price and a stated flow for.

No vent run to pay for, but the gas line, the water lines to the outside wall and an outlet for the freeze protection still come on top.

A better fit for your house?

Two showers and the dishwasher at once? The A. O. Smith 10 GPM Natural Gas Outdoor (8.0/10) states up to 10 GPM.

Hard freezes where you live? The ThermoMate CZ422LP Propane Indoor (7.8/10) 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

We like the STPFFOT 130,000 BTU Propane Outdoor for up to 5.2 GPM and an outside-wall install with no vent run. Only 2 buyers have rated it so far (5.0/5), so treat the score as an early read. The catch with this STPFFOT outdoor tankless heater: no word on the warranty. We'd pick it if there is no good vent route inside your house; otherwise, put it next to the VELPAX 20L Natural Gas 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 130,000 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 5.0/5, an excellent record, well above our ranked picks' 4.3 average. Only 2 reviews so far, and our formula damps averages built on fewer than 50.

Ranked picks' average: 4.3/5

The one thing we'd check first

Before the STPFFOT 130,000 BTU Propane Outdoor ships, check your gas line: 130,000 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

5.2 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 STPFFOT 130,000 BTU Propane Outdoor any good?

We rate it 7.0/10 (good). The rating comes from its documented listing alone, as no customer-review record is captured yet.

How much hot water can the STPFFOT 130,000 BTU Propane Outdoor deliver?

The listing states a maximum flow of 5.2 GPM and a gas input of 130,000 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 STPFFOT 130,000 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 STPFFOT 130,000 BTU Propane Outdoor?

Its listing states up to 5.2 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 STPFFOT 130,000 BTU Propane Outdoor?

Your winter flow: 5.2 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.
