two questions: 1)are electric tankless water heaters reliable? 2)what companies make the best tankless water heaters? …ok, really three questions: 3)SETS system: they have a life-time guarantee, but i’ve heard that the quality is not-so-good.
background: i need to purchase a hot water heater to replace the ten-year-old one that came with my condo. the building, a high-rise, has no gas, so i’m limited to electric, so that’s not really an issue. i like that tankless systems because they’re spacesavers, but i’m concerned about reliability and quality.
