What winter here does to your water heater
Groundwater coming into your house is cold for seven months of the year, December through February especially, when nights average 23°F. Your water heater has to work harder through that stretch to get water up to temperature, and the parts that do that work, the heating element in an electric unit or the burner and thermocouple in a gas one, take the wear. That's when a lot of people notice the shower running lukewarm instead of hot, or the recovery time getting longer between uses.
Power loss is part of it too. Indiana saw 17% of households lose power for 24 hours or more in 2024, and Vigo County has had 49 damaging wind events and 5 winter storms over the past ten years. An electric water heater won't heat while the power is out, and some won't come back on by themselves once it returns. If yours has a pilot light, that part stays lit through an outage, but the rest of the unit still depends on power to run safely.

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 and is starting to fail. Sediment builds up in the bottom of the tank over years and eats away at the lining until it lets go, and once a tank is leaking that way it needs to be replaced, not patched. The leak can also come from a fitting, the drain valve, or the temperature and pressure relief valve, and those are worth checking before you assume the tank is done. A contractor can tell you in a few minutes which one it is.
- 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 can't sense the flame anymore, so the gas valve shuts off the pilot as a safety measure. A dirty pilot orifice or a draft blowing the flame out can cause the same thing. Any of these is a straightforward fix for a contractor, but don't keep relighting it over and over if it won't hold.
- Can a tankless water heater be repaired?
- Yes, most tankless water heater problems are repairs, not replacements. The heat exchanger, the igniter, and the flow sensor are the parts that fail most, and a contractor can test which one it is and replace just that part. Mineral buildup inside the unit is another common issue, especially if the water heater has never been flushed, and that's often a service rather than a repair. A full replacement is usually only needed when the heat exchanger itself has cracked or corroded through.
