How many fixtures can it run at once?

The 4.8 GPM rating is meant for three to four hot water points running together. Actual output drops in cold weather, when incoming water is colder.

Will it work with a low-flow showerhead?

Yes. It activates at a minimum flow of 0.6 GPM, so low-flow fixtures still trigger the burner.

Can it be installed outdoors?

No. It is built for indoor installation and comes with an exhaust pipe for venting.

Does it run on natural gas?

No. It is a propane unit, so you need an LP supply and the matching regulator and line.

Is it a condensing heater?

No. It is a standard non-condensing tankless unit, so it vents hotter exhaust and is less efficient than condensing models.

Our take on the STPFFOT Gas Tankless Water Heater for Indoor, 18 L Capacity with Exhaust Pipe

The STPFFOT is an indoor propane tankless water heater rated for 4.8 GPM, enough to feed three or four hot water points at once. It starts on flows as low as 0.6 GPM, so a single tap or a low-flow shower still triggers it. It ships with an exhaust pipe for venting indoors. Against rivals in the same class, it targets whole-house duty rather than a single bathroom, but it is a propane-only, indoor-only unit with no condensing design, so efficiency and venting demands are higher than with a condensing model.
