What is how long does it take for hot water to come back after shower?

After a shower, the time it takes for hot water to return depends on several factors:

• Water Heater Type and Size: Tank water heaters need time to reheat the water in the tank. A larger tank will take longer to reheat fully than a smaller tank. Tankless water heaters provide hot water on demand, so recovery time is minimal.

• Water Heater's Recovery Rate: This is a measure of how quickly a tank water heater can heat a certain amount of water (e.g., gallons per hour).

• Distance from Water Heater to Shower: The further the shower is from the water heater, the longer it will take for the hot water to travel through the pipes.

• Pipe Insulation: Insulated pipes help retain heat, reducing the time it takes for hot water to reach the shower.

• Usage Patterns: If multiple people are using hot water at the same time, the recovery time will be longer.

General Estimates:

• Tankless Water Heater: Hot water should be available almost immediately, with a very short lag time.
• Tank Water Heater: Could range from 20-60 minutes or more to fully recover, depending on the factors mentioned above. It also depends on how much water was used. If just a little was used, it could be quick, but if a lot was, it may take longer.
