What Stockton winters do to a water heater

Nights average 40°F from December through February, and your water heater works harder those months to keep the tank up to temperature. That means more cycles on the burner or the heating element, and more cycles is what wears either one down.

Power matters too. San Joaquin County has logged 21 damaging wind events over the past ten years, and statewide, 17% of households lost power for a full day or more in 2024. A gas water heater with a standing pilot keeps working through an outage. One with electronic ignition will not relight on its own, and you will notice cold water until it is reset or repaired.

Hot water flows from a brushed stainless steel faucet into a sink, surrounded by rising steam.

A new water heater would cut about $110 a year off hot water for a typical California home.

  • A new high-efficiency gas water heater$240 a year
  • A heat pump water heater$300 a year
  • An older gas water heater$350 a year

Estimates for a typical California home, compared with an older unit built to the federal minimum, from EIA household energy data and California fuel prices. Your home will differ.

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 itself has likely rusted through and started leaking. Water heaters corrode from the inside over the years, and once the tank wall gives way, no seal or fitting fixes it. It could also be the drain valve or a fitting that's failed, which is a smaller repair. A contractor can tell the difference by drying everything off and watching where the water shows up first.
Why won't the pilot light on my water heater stay lit?
A dirty or failing thermocouple is the most common reason a pilot won't stay lit. The thermocouple senses the flame and tells the gas valve it's safe to keep gas flowing, and once it's worn out or coated in soot, it shuts the gas off even though the pilot lit fine. A weak gas supply or a draft near the pilot can cause the same thing. A licensed contractor can test the thermocouple and replace it if that's the cause.
Can a tankless water heater be repaired?
Yes, most problems with a tankless water heater are repairable. Mineral buildup on the heat exchanger is common and usually calls for a descaling flush rather than a new unit. Ignition failures, sensor faults and venting issues can often be fixed by replacing the specific part that failed. A contractor can run the unit's error code to find out what's actually wrong before recommending a repair.
