A 110V under sink water heater eliminates this waiting time and only heats up the amount of water that you need, thus saving both time and energy.

3. Space-saving: Traditional water heaters are bulky and take up a lot of space, usually in the basement or utility room. However, with an under sink water heater, you can utilize the space under your kitchen or bathroom sink which would otherwise go unused.
