If water from your hot water heater is no hot enough even after checking that the thermostat is set correctly, there are a number of things to check.
1. The Dip Tube Is Damaged
The dip tube is where the cold water enters the water heater and is sent to the bottom of the tank so it can be quickly heated. If the tube is damaged the water will remain at the top of the tank, where the hot water outlet is, causing it to return cold water to get returned with the heated water.
2. Sediment Has Accumulated at the Base of the Tank
Minerals in the water can build up at the bottom of the water heater over time. This will result in a gradual loss of heating efficiency, as the burners work harder to heat the water. Sometimes, when a tank has sediment you will be able to hear a gurgling sound as the water boils through the layer of sediment. Flushing the tank annually will prevent sediment build-up.
3. The Water Heater's Heating System Is Malfunctioning
Most water heater problems can be traced to these systems:
- Thermal switch
- Heating element
A licensed plumber should inspect the water heater and repair the pasts as needed.
4. The Water Heater Is Too Far From Where Hot Water Is Needed
If the water eventually get hot enough after a running for a while, the problem is often that the tank is too far away from where hot water is needed. In the winter, pipes will cool the hot water before it reaches the faucet where it's needed. Insulating the pipes can help reduce heat loss.
5. The Water Heater Tank Is Too Small
If you're noticing that your water heater is running out of water suddenly it could be that your water heater tank is simply too small to keep up with demand. Installing a larger tank or tankless water heater will ensure that you have all the water your household needs.
