Hot Water Runs Out Fast? Here's Why and What to Do

Hot water runs out fast in your home? A failed lower element, a broken dip tube, sediment, or an undersized tank are the usual causes. Learn the fix from NH water heater experts.

Electric heater: a dead lower element

Electric tanks have two elements. When the lower one fails, only the top third of the tank heats — a hot start and a fast cold finish. Element replacement is a quick repair.

Broken dip tube

The dip tube sends cold water to the bottom of the tank. When it cracks, cold water mixes at the top and the shower goes lukewarm in minutes.

Sediment and undersizing

Sediment takes up tank volume; flushing restores some capacity. If the household has outgrown a 40-gallon tank, a larger tank or a tankless water heater ends the problem for good.
