Sacramento County water heaters run hard for six months straight
Water heaters here work through the winter along with the furnace, November through April. On nights averaging 40°F, the tank cycles more just to hold its temperature, and that extra run time wears on the heating element and the thermostat that controls it.
Power matters too. About 17% of California households lost power for a day or more in 2024, and the county has seen 54 damaging wind events over the past ten years. A gas water heater with a standing pilot keeps working through an outage. One with electric ignition or a heat pump unit will not, and you will notice hot water not coming back until the power does.

A new water heater would cut about $110 a year off hot water for a typical California 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 most common reason is that the tank itself has rusted through and is failing from the inside. Sediment builds up at the bottom of the tank over years, and once it wears through the steel, water finds a way out. A loose drain valve or a fitting can also leak from the bottom, and those can be fixed. A tank that's actually rusted through cannot be repaired, it needs to be replaced. A contractor can tell you which one you're dealing with by looking at where the water is coming from.
- Why won't the pilot light on my water heater stay lit?
- Most of the time this means the thermocouple has worn out. That's the small sensor that sits in the pilot flame and tells the gas valve it's safe to keep sending gas. Once it wears out or sits out of position, the valve shuts the gas off even though the pilot lit for a second. A dirty pilot orifice or a draft in the area can also blow the flame out. A thermocouple is a cheap part to replace and usually solves it on its own.
- Can a tankless water heater be repaired?
- Yes, most problems with a tankless water heater can be fixed without replacing the whole unit. The igniter, the flow sensor, and the heat exchanger can all be worked on individually. Mineral buildup inside the heat exchanger is a common issue in any home that hasn't had the unit flushed in a while, and that can be cleared out rather than replaced. A contractor will need to check the specific error code or symptom to know which part is at fault.
