One of the main reasons hot water takes a long time to reach the faucet is simply due to the distance between the water heater and the fixture. The further away a fixture is from the water heater, the longer it takes for the hot water to travel to it..
Also question is, why does my hot water take so long to come through?
There's several reasons; the distance from the water heater, the diameter of the piping, and the flow rate of the water. The further the hot water has to flow, the longer it takes to heat up the shower faucet. Another reason for a delay in hot water is the water that is currently in the pipes.
Additionally, why does it take so long to get hot water from my tankless water heater? Some fixture mixing valves also create issues with tankless water heaters because of the way they balance flow between the hot and cold feeds.

If you want to loll in your own 15-minute shower, you'll need to wait 47 minutes before stepping in. (Gas units heat faster, so multiply by 1.9 instead of 4.3.)

Water Heater Runs Out Of Hot Water Quickly: Possible Reasons Why. As mentioned above, several things can cause a home's hot water supply to run out faster than it should. The three most common culprits are sediment build up, a faulty heating element and a broken dip tube.
