A water heater with a tank preheats water and stores it in a large tank until the water is needed. Tankless heaters do not store any water, they quickly heat it as it is being used.
Sometimes tankless water heaters are call “on-demand” water heaters for this reason. A traditional tank model is less expensive to install, but uses more energy and raises utility costs, which can add up over time. Also, a tankless water heater will typically have a longer lifespan, so you won’t need a replacement as soon.
Tankless models provide on-demand hot water, it can run into issues providing a lot of hot water to multiple fixtures at the same time. A traditional tank model however, does run out of water and takes time to re-fill and re-heat. So there are pros and cons to both types. There are also hybrid options that offer the best of both worlds.
Tankless water heaters can run on electricity, natural gas, or propane. There are benefits to each type, and this should be considered for each home. Gas may increase capacity, but electric models are typically more efficient and have lower costs.
