Up to 8.1 GPM from a 190,000 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 two showers and a kitchen tap, less when the water comes in cold.

What it has going for it

What changes in the morning shower rush

0.81 UEF. Uniform Energy Factor is the federal efficiency label: the higher it is, the less gas or power goes up the vent instead of into your shower.

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.

Mild winters or hard freezes?

Mild winters: an outside wall is the easy spot. No vent through the roof or the rim joist, no combustion air to plan inside the house.

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

Skip it if…

You want a tight temperature hold: the listing claims no ±1 °F control
Your winters freeze hard and the outside wall has no power for freeze protection
You'd rather wait for buyer reviews: none are captured for this listing yet

What Konfino promises

The seller states, word for word, in the Konfino 190,000 BTU Natural Gas Outdoor listing:

Space-saving 24.3 x 15 x 8.3 inch heater installs outdoors and keeps the indoors clutter-free.
Wind-resistant ten-level outdoor heater with electric anti-freeze plus freeze, overheat and flame-failure protection.

Their words and their figures, not our measurements. How steady your shower stays when someone opens the kitchen tap, and what's left of that flow in January, no listing can tell you.

Price and cost per GPM of stated flow

$529.79 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 $65.41 (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.

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?

Hard freezes where you live? The Ranein 190,000 BTU Natural Gas Indoor (7.9/10) is an indoor unit, out of the frost.

Want the high-efficiency kind? The Rheem RTGH 8.4 GPM Natural Gas Indoor (7.3/10) is a condensing unit, per its listing.

The far bathroom takes ages to run hot? The Rinnai REP199eN Smart-Circ (7.3/10) has built-in recirculation, per its listing.

Our take

The verdict

Our favourite thing about the Konfino 190,000 BTU Natural Gas Outdoor is an 8.1 GPM maximum flow, closely followed by a 0.81 UEF rating. No buyer reviews yet, so the Konfino 190,000 BTU Natural Gas Outdoor has to win you over on paper. The catch with this Konfino outdoor tankless heater: no stated temperature hold, while most picks here claim ±1 °F. We'd pick the Konfino if you run one shower and the kitchen tap at once, rarely more; otherwise, put it next to the LiberLive 130,000 BTU NG Outdoor in Gray 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 190,000 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. 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.

The one thing we'd check first

Before the Konfino 190,000 BTU Natural Gas Outdoor goes in your cart, check your gas line: 190,000 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

8.1 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.

How it compares

How the Konfino 190,000 BTU Natural Gas Outdoor stacks up against the closest alternative, the LiberLive 130,000 BTU NG Outdoor in Gray.

Both score 7.3/10. The LiberLive 130,000 BTU NG Outdoor in Gray adds a longer stated warranty (2 years), while the Konfino 190,000 BTU Natural Gas Outdoor brings more flow (8.1 GPM) and a bigger burner (190,000 BTU/h).

Frequently asked questions

Is the Konfino 190,000 BTU Natural Gas Outdoor any good?

We rate it 7.3/10 (good). The rating comes from its documented listing alone, as no customer-review record is captured yet.

How much hot water can the Konfino 190,000 BTU Natural Gas Outdoor deliver?

The listing states a maximum flow of 8.1 GPM and a gas input of 190,000 BTU/h on 120 V. 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 Konfino 190,000 BTU Natural Gas 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 Konfino 190,000 BTU Natural Gas Outdoor?

Its listing states up to 8.1 GPM, a 0.81 UEF rating and outdoor mounting that skips the flue. 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 Konfino 190,000 BTU Natural Gas Outdoor?

Your winter flow: 8.1 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.

Where can I buy the Konfino 190,000 BTU Natural Gas Outdoor?
