Enjoying a hot shower after a hard day's work is one of life's small joys. However, when your water heater suddenly overheats, it can take all the pleasure out of your showering experience. This unpleasant situation can result from various issues, ranging from a faulty thermostat to an accumulation of sediment.

If you're wondering why your water heater is overheating and how to fix it, this article will provide you with all the answers you need!

Sediment Buildup

Sediment can be from minerals like calcium and magnesium that have accumulated in your water heater over time. It can also be caused by corrosion of pipes leading to the water heater.

The buildup can act as an insulator, trapping heat in your water tank and causing it to overheat. If you've noticed a decrease in water pressure or reduced hot water flow, this could be a sign of sediment buildup.

To resolve this issue, contact a local plumber to clean the sediment from your tank. The plumber can also offer solutions like installing a water softener to prevent the sediment from building up again.

Faulty Thermostat

A malfunctioning thermostat may be caused by an electrical surge, wear and tear, or incorrect calibration. The water can overheat if the thermostat cannot detect and keep the water temperature at the set level.

Before contacting a professional, try resetting the thermostat and check if that resolves the issue. If it does not, you'll need an experienced plumber to inspect and repair your water heater's thermostat or replace it entirely. The professional will also check if your water heater needs insulation or not.

Leaking Tank

A leaking tank can cause your water heater to overheat. Leakages can also originate from valves or pipes connected to your water heater. Leakages can reduce the amount of water in the tank, making it harder for the heating element to maintain a steady temperature.

If you suspect your tank leaks, contact a professional plumber immediately. The plumber will check whether replacing the valves or pipes connected to your water heater is necessary.

Incorrect Size

The size of your water heater is important because it should be able to accommodate the household's hot water needs. If the size is too small, it can struggle to keep up with demand and become overworked. This can lead to a higher temperature and eventually overheating.

A plumber can help you determine the right size for your water heater. They can also advise on the best type of water heater for your home, including tankless and solar-powered models.
