What winter here does to your water heater
Clay County homes run their water heaters through seven months of cold weather, October through April. When groundwater runs colder on nights that average 22°F, the burner or heating element has to work longer to bring the tank up to temperature. That extra run time wears on the burner and igniter in a gas tank, or the heating element and thermostat in an electric one.
Power is part of it too. In Missouri, 19% of households went at least 24 hours without power in 2024, and this area has logged 116 damaging wind events and 9 winter storms over the past ten years. Most electric water heaters come back on by themselves once power returns. If yours does not reheat after an outage, that is worth a look.

A new water heater would cut about $80 a year off hot water for a typical Missouri home.

Repair makes sense when an element, thermostat or gas valve has failed.
Replacement makes sense when the tank itself is leaking.
- Why is my water heater leaking from the bottom?
- The tank has likely rusted through from the inside and is starting to fail. Water heaters corrode from the inside out over years of use, and once the tank itself is leaking, it cannot be patched or sealed. A puddle at the base can also come from a loose drain valve or a fitting on the cold water line, so it's worth checking those before assuming the tank is done. If the water is coming from underneath the tank itself, the unit needs to be replaced.
- Why won't the pilot light on my water heater stay lit?
- The most common cause is a worn thermocouple, the small sensor that tells the gas valve the pilot is burning. When it wears out, it fails to sense the flame and shuts the gas off as a safety measure. A dirty pilot orifice or a draft near the burner compartment can cause the same thing. This is a gas component, so it should be diagnosed and fixed by a licensed contractor rather than adjusted on your own.
- Can a tankless water heater be repaired?
- Yes, most tankless water heater problems are repairable. Issues like a failed igniter, a clogged inlet filter, mineral buildup on the heat exchanger, or an error code from a sensor can usually be fixed without replacing the unit. Because these run on gas or electricity and often involve venting, a licensed contractor should diagnose the specific error before any part is replaced.
