Electric Tankless Water Heater with Self Modulating Technology

first impression: when the courier called ahead for delivery, i was excited to set it up. as a software developer, i appreciate the smart way it modulates heat on the fly, but i've noticed it struggles a bit during peak usage times. it's energy efficient, only heating when needed, which aligns with my pragmatic approach to saving money. overall, it does the job well for a single person household, but it's not perfect—could be better for larger families or heavy use scenarios. i'd recommend it with some reservations.
- Pros: the endless hot water is incredibly convenient, especially for showers that never run cold. it adjusts automatically to keep the temperature just right, which saves energy and reduces waste. the compact size is a huge plus, fitting easily in small spaces without being obtrusive.
- Cons: it could be wrong, but the water flow might not be sufficient for multiple uses at once, leading to some lukewarm moments. installation required checking my home's electrical setup carefully, which was a bit of a hassle. the initial cost felt high compared to traditional options.
