What to Do If Your Water Is Taking Too Long to Heat

When you need hot water in your home, you don’t want to wait. If your shower takes too long to warm up or you’re dealing with slow hot water throughout your home, there are some things you can do to fix your hot water woes!

5 Reasons You Have to Wait For Hot Water From Your Home’s Tap

  • Distance. The farther away your water heater is from the faucet or shower where you want hot water to flow, the longer it will take to get there.
  • A low volume restrictor. You may have a low volume restrictor installed on fixtures, like your shower, which can delay the delivery of water.

  • A failing water heater. Water heaters that are about ten years old are at the end of their service life. That can mean they fail suddenly, or they’re simply less effective at heating water. An expert plumber from NDI can check out and repair your water heater and determine if now’s the right time for a water heater replacement
  • Sediment buildup. Sediment accumulates in your water heater when dissolved minerals, such as calcium and magnesium, settle on the bottom of the tank. Unfortunately, this is precisely where the electric heating element or gas burner is located. With a crusty layer of sediment blocking heat transfer, the tank can’t produce hot water as quickly as it used to. A water heater professional from NDI can flush your water heater and clean out the sediment to help improve efficiency and performance.

  • Undersized water heater. Perhaps you installed a water heater several years ago when only two people lived in your home. If your family has grown since then, you could be demanding more from your water heater than it’s designed to handle. Upgrading to a larger unit could be the solution to your problem.

How Long Does It Take to get Hot Water Back?

All storage water heaters have a particular recovery time. This is the amount of time it takes the tank to deliver hot water again after it has been depleted. The recovery time can vary widely depending on these factors:

  • Tank size: Larger tanks take longer to recover

  • First-hour rating (FHR): The higher the FHR, the less time it takes for the water heater to recover
  • Fuel type: Electric water heaters take about twice as long to reheat as gas models
  • Temperature rise: Cold incoming water takes longer to reheat than warm water.

Overall, it takes an average of 80-gallon water heaters about an average to recover. The factors outlined here determine whether your water heater’s recovery time is longer or shorter than this.

How Can I Get Hot Water Faster?

Hot Water Recirculation System

A hot water recirculation system can reduce the amount of water wasted while you’re waiting for it to heat up from the tap. A recirculation system:

  • Moves water more quickly from the water heater to the desired tap

  • Recirculates your used water back to the heater and keeps hot water close to the faucets

  • It’s activated by a timer or a thermostat

The recirculation system can be either mounted near your faucet or attached to your water heater. The version attached to your water heater includes a pump and a timer to keep the hot water circulating.

A Tankless Water Heater

A tankless water heater is another option to provide on-demand hot water continuously. Offering an endless supply of hot water, tankless water heaters don’t use tanks to contain or heat water. Instead, water passes over a heating element to instantly become hot.

The result is immediate access to hot water and a reduction in heating costs because the tank isn’t heating unused water.

In addition to whole-house tankless water heaters, there are also point-of-use tankless water heater units. These smaller units addressed hot water output for individual faucets and can be installed in a sink, cabinet or closet. These are a good option when a water heater can’t serve the entire home.

Given that water heaters can account for as much as 25% of a home’s energy use, choosing an efficient system that can also meet your water heater’s needs is crucial. The team at NDI Plumbing can help with that to ensure you get a water heater that fits your budget and your hot water needs while providing optimal long-term value!
