Tankless or tank — which water heater makes sense?
Both work. Neither is automatically better. The right choice depends on how your household actually uses hot water.
A tank water heater keeps a volume of water hot and ready all the time. When you draw off hot water, cold refills and the tank reheats. It's simple, proven, and the standby losses — the energy spent keeping water hot while you're not using it — are the trade-off.
A tankless (on-demand) heater warms water as it flows through, so there's no standby tank and no stored volume to keep hot. The advantages are continuous supply and no idle losses. The trade-offs are a finite flow rate — only so much hot water at once — and, for gas units, a larger gas supply and proper venting to handle the high burn rate.
Which one makes sense depends on how the household actually uses hot water: how many simultaneous draws, how often, and the gas and venting situation. A big family filling two bathrooms at once has different needs than a single person who wants endless showers. The right answer comes from the usage, not from whichever one is being promoted this month.
