Tank vs. Tankless Water Heaters

Tankless water heaters present an alternative to conventional tank water heaters. Tankless units generally take up less space, can be mounted on a wall, and only heat water on demand. Although tank-style water heaters expend extra energy to keep their storage tanks warm at all times, they are the preferable option in many applications. Tankless heaters can provide hot water indefinitely – but only if the maximum per-minute flow rate of a unit at the required temperature rise is not exceeded. This makes them an ideal choice for homes and applications in which extended use at relatively low flow rates is the norm. Since conventional tank water heaters have a pre-heated reserve of hot water, they function more effectively when heavy bursts of simultaneous hot water usage can be anticipated.
