Waiting on a tank to heat up before a shower, or squeezing a bulky water heater into a tiny bathroom closet, gets old fast — this tankless water heater delivers hot water on demand in about three seconds, right at the sink or shower where you need it. It's roughly the size of a carry-on bag, so it mounts under a kitchen or bathroom sink, in a closet, or on almost any wall, heating your whole house or just one fixture at a time. If a leak has you worried about running an electric heater near water, it shuts itself off automatically the moment one is detected.
Because it heats water as it flows through instead of storing it in a tank, you get fresh water every time instead of the rust and scale a tank-style heater can build up. The stainless steel body is built to last, and several safeguards work together behind the scenes: dry-heating protection, water-and-electricity isolation, and automatic shutoff if it overheats or sits unused for a while.
Call it an energy efficient water heater, an rv water heater, or an on demand water heater — this portable water heater answers to all three, and doubles as a small water heater for a single bathroom or an under sink water heater for the kitchen. As a point of use water heater it installs right where you need hot water, and as a hot water heater electric option, it skips the tank altogether.
