Did you just move into a new home? Have you found that the home quickly runs out of hot water? Even with the most thorough inspections, there are some things you just can't learn about a house until you move into it. If you're running out of hot water on a frequent basis, there could be a few possible reasons. While some may be very simple, others could require major water heater repair or even a hot water heater replacement. Here are three reasons why your home may not have enough hot water:

The water heater is undersized for your family's demands. This is one of the most common reasons why homes run out of water. You're simply demanding more hot water than the water heater can provide. Think about when you run out of hot water. Is it at the end of your family's morning routine? Is it at night after your children take baths? If so, supply and demand issues could be the source of the problem. A water heater professional can inspect your heater and let you know how much hot water you're using and whether your heater is sufficiently sized to meet the demand.

Cold and hot water are mixing in the tank. Water is cold when it enters your water heater. It enters through a dip tube, which places the cold water at the bottom of the tank. The cold water then heats up as it rises through the tank. However, if your dip tub is damaged, cold water could be leaking into the middle or top of the tank and could be coming out of the tank before it has the chance to heat. You can shut off water to the heater and remove the dip tube for inspection. If it has a crack or hole, then it likely needs to be replaced.

Cold and hot water lines are mixed. This is a mishap that can happen during construction or during appliance installation. If only one water outlet has a hot water issue, then this is likely the cause. Whoever installed the outlet simply crossed the lines and accidentally hooked the hot water line to a cold water outlet. Turn off water flow to your hot water heater. Then turn on the hot water at the affected faucet or appliance. If water comes out, then you know that it's pulling cold water instead of hot water. A plumber could help you resolve the issue.
