Also called on-demand or instant hot water systems, these unique devices have no need for a large water storage tank, as they only heat the water when you actually need to use it in your home. Because they don’t have to maintain a large amount of hot water at any given time, instant water heaters are much more energy-efficient than their traditional tank-based counterparts, potentially saving you a lot of money over time.
