Cold winters put extra load on your water heater
Winter nights here average 24°F from December through February, and the water coming into your tank starts out cold. The heating element or burner has to run longer to bring it up to temperature, and that extra runtime is what wears out an electric element or a gas igniter over enough winters.
Cass County has recorded 9 winter storms and 89 damaging wind events over the past ten years, and in Missouri, 19% of households went at least 24 hours without power in 2024. A gas water heater with electronic ignition will not relight on its own once power drops out mid-cycle. If yours went quiet during an outage and never came back, that is usually why.

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 most common cause is the tank itself failing from the inside, where sediment builds up and corrodes the steel until it gives way. Once a tank is leaking like this, it cannot be patched or sealed, it needs to be replaced. A leak can also come from a loose drain valve or a fitting where a pipe connects to the tank, and those can sometimes be tightened or repaired. A contractor can tell you which one you're dealing with by looking at where the water is actually coming from.
- Why won't the pilot light on my water heater stay lit?
- Usually the thermocouple has worn out and can no longer sense that the pilot is burning, so it shuts the gas off as a safety measure. It can also mean the pilot tube is dirty or there is a draft in the area blowing the flame out. A thermocouple is a simple, inexpensive part to replace. If replacing it does not fix the problem, there may be a gas supply issue that needs a closer look.
- Can a tankless water heater be repaired?
- Yes, most problems with a tankless water heater are repairable. Error codes usually point to something specific, like a blocked vent, a buildup of scale on the heat exchanger, or a failed sensor, and each of those has a fix. Scale buildup is common in units that have not been flushed regularly, since minerals in the water collect inside the heat exchanger over time. A contractor can read the error code and check the unit to know exactly what needs attention.
