Precisely as the name implies, tankless water heaters are water heaters without the tank. They are the Netflix to your DVD collection. Instead of storing hot water in waiting, a tankless water heater warms the water up when you are ready for it.
These energy-efficient heaters are relatively small, sometimes no bigger than a suitcase. You can install them on a wall, in between studs, or even under a cabinet.
These bite-sized powerhouses pack a big punch of benefits over their larger, more traditional competitors.
