What Greenwood winters do to a water heater
Groundwater coming into your house is coldest from December through February, when Johnson County nights average 23°F. Your water heater has to work harder to bring that water up to temperature, and it runs longer to do it. That extra runtime wears on the heating element in an electric unit or the burner assembly in a gas one, and it's often when a tank that was already struggling finally quits.
Johnson County has seen 39 damaging wind events and 11 winter storms over the past ten years, and statewide, 17% of households lost power for 24 hours or more in 2024. If your water heater is electric, an outage means no hot water until power is back. Gas units with a standing pilot keep working through an outage, but many newer ones use an igniter that needs electricity to start, so it's worth knowing which kind you have before the next storm hits.

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?
- Most often the tank itself has rusted through from the inside. Sediment builds up at the bottom of the tank over years, and once it wears through the lining, water finds a way out and the tank can't be patched or repaired. It could also be a loose drain valve or a fitting that's failed, which a contractor can check before assuming the worst. If the leak is coming from the tank itself, the water heater needs to be replaced, not repaired.
- Why won't the pilot light on my water heater stay lit?
- The thermocouple is the most common reason. It's the small sensor that sits in the pilot flame and tells the gas valve the flame is lit. Once it wears out or sits at the wrong angle, it stops sensing the flame and shuts the gas off even though the pilot is burning. A dirty or clogged pilot orifice, a draft, or a failing gas valve can cause the same thing, so a contractor will need to see which one it is. Don't keep relighting it over and over if it won't hold. That points to a part that needs replacing, not a fluke.
- Can a tankless water heater be repaired?
- Yes, most problems with a tankless water heater are repairable. Mineral buildup on the heat exchanger, a failed igniter, a bad flow sensor, or an error code from the control board are all things a contractor can diagnose and fix without replacing the unit. Tankless units also last a long time when descaled and serviced, so repair is usually the right call. A contractor can look at the specific error and tell you whether it's a repair or whether the unit has reached the end of its life.
