Why does it take so long for my water to heat up?

You don't want to wait for hot water in your home when you need it. There are several things you can do to cure your hot water troubles if your shower takes too long to warm up or you have sluggish hot water throughout your house!


  1. Distance: The greater the distance between your water heater and the faucet or shower where you want hot water to flow, the longer it will take.
  2. Faulty Water Heater: Water heaters that are 10 years old or older are nearing the end of their useful life. This might indicate that they failed unexpectedly, or that they are just less efficient at heating water. A skilled plumber from Len The Plumber can inspect and repair your water heater to decide if it is time to replace it.
  3. Low volume restrictor: A low volume restrictor may be put on fixtures such as your shower, which might cause the water supply to be delayed.
  4. Sediment accumulation: occurs when dissolved minerals, such as calcium and magnesium, collect on the bottom of the tank—exactly where the electric heating element or gas burner is located. The tank can't create hot water as rapidly as it used to because a crusty coating of silt is obstructing heat transmission. Edge's water heater experts can flush your water heater and clear out the sediment to increase efficiency and performance.
  5. Undersized water heater: Perhaps you built a water heater some years ago when you just had two people living in your house. If your family has expanded since then, you may be expecting more from your water heater than it can. Upgrading to a bigger unit may be the answer to your problem.


All storage water heaters have a recovery time. This is the time it takes for the tank to re-deliver hot water once it has been drained. The time it takes to recover might vary significantly based on the following factors:

  • Tank size: Larger tanks require more time to recover.
  • Electric water heaters take almost twice as long to warm as gas units.
  • First-hour rating (FHR): The greater the FHR, the faster the water heater recovers.
  • Temperature rise: It takes longer to reheat cold entering water than warm water.

Overall, it takes roughly an hour for a typical 80-gallon gas water heater to recover. The parameters discussed above affect whether the recovery period of your water heater is greater or less than this.


Hot Water Recirculation System

A hot water recirculation system might help you save water as you wait for it to heat up from the faucet. A recirculation system:

  • Increases the speed with which water is sent from the water heater to the selected tap.
  • It returns used water to the heater and keeps hot water near the faucets.
  • It is set off by a timer or a thermostat.

The recirculation system may be coupled to your water heater or positioned near your faucet. The model that is connected to your water heater has a pump and a timer to keep the hot water moving.

Given that water heaters may account for up to 25% of a home's energy use, selecting an efficient system that can also satisfy your water heater demands is critical. Edge can assist you in this process to guarantee that you receive a water heater that meets your budget and your hot water demands while also giving the best long-term value!
