The last thing you want when you take a shower is to run out of hot water. When you live alone, this issue can be an annoyance, but when multiple people in a household need hot water, it can be downright disruptive. So, why does hot water run out after one shower? In this post, our experts explain three common causes and what you can do about it.
Sediment build-up inside of your water heater tank is a common reason for hot water that runs out. Minerals and sediment are deposited in your water heater. With time, they sink to the bottom and build up, creating a barrier between the heating elements and your water. In extreme cases, sediment can also take up space, which means your water heater will have less room to store hot water.
The Fix: A qualified HVAC technician can flush your tank to clear out sediment. Moving forward, regular water heater maintenance will help prevent this problem.
Insufficient Water Heater Size
If you’ve tried flushing your water heater and you still run out of hot water after one shower, your water heater might be too small. If you live with multiple people, your water heater could struggle to keep up with the demand.
The Fix: On average, a household with 3-4 people requires a tank with a 40–50-gallon capacity. If you’re not sure about the optimal water heater size for your family, an HVAC technician can assess your situation and make recommendations based on your needs.
Water Heater Age
If your water heater is more than 10-years-old, it might be nearing the end of its lifespan. An aging water heater will become less efficient as time goes on.
The Fix: Contact an HVAC professional to replace your old water heater with a new system.
