One demand or many
Point-of-use equipment works best when the fixture and flow are clearly defined. It is not automatically a substitute for whole-home capacity.
Hot water close to the fixture
Use a compact point-of-use water heater for a remote sink or small demand when long pipe runs, limited use, or a specialized fixture makes a whole-building change unnecessary.

The symptom is only the starting point. These details help separate a lasting repair from a short-term patch.
Point-of-use equipment works best when the fixture and flow are clearly defined. It is not automatically a substitute for whole-home capacity.
Small electric units still require a correctly sized circuit, wiring, disconnect, and installation that matches the manufacturer's instructions.
A mini-tank stores a small volume for quick use. A compact tankless unit depends on incoming temperature, flow, and electrical capacity.
Phoenix Valley context
When a sink is far from the central heater, a point-of-use unit may reduce the wait without changing every hot-water line. Recirculation can be another option and should be compared.

Common questions
Only equipment sized for the required shower flow and temperature rise should be considered. Many small units are intended for sinks and cannot provide comfortable shower demand.
It depends on space, power, flow, frequency, and how quickly the stored volume may be used. A small tank can be simple for intermittent sink use, while tankless needs adequate electrical capacity.
Possibly. If several fixtures wait for hot water, a properly designed recirculation strategy may address the whole branch. One remote fixture may favor point-of-use equipment.
