Cold winters and power outages both work against your water heater
Cedar City needs heat from October through May, eight months a year, and winter nights average 20°F from December through February. Cold weather like that means the water coming into your tank starts out colder, so the burner or heating element has to run longer and more often to bring it up to temperature. That extra cycling wears on the thermostat and the heating element or burner assembly over time.
The county has logged 36 winter storms and 32 damaging wind events over the past ten years, and outages follow storms like that. Most water heaters come back on by themselves once power returns, but a gas unit with a standing pilot needs to be relit by hand. Either way, a day without power means cold water until the tank catches back up.

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 it means the tank itself has rusted through and is starting to fail. Water heaters corrode from the inside over the years, and once the tank wall is breached, no seal or fitting will stop it. It can also be a loose drain valve or a failed temperature and pressure relief valve, both of which a contractor can check before assuming the tank is done. If the leak is coming from the tank itself, the unit needs to be replaced, not repaired.
- Why won't the pilot light on my water heater stay lit?
- A pilot that won't stay lit is usually a sign 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 gas flowing. Once it wears out, it can't confirm the flame is lit, so the gas valve shuts things down as a safety measure. A dirty pilot orifice or a draft blowing out the flame can cause the same symptom, so a contractor will check both before replacing anything.
- Can a tankless water heater be repaired?
- Yes, most tankless water heater problems are repairable. Common issues include a clogged inlet filter, a buildup of mineral scale on the heat exchanger, or a failed igniter, and each of those can be cleaned or replaced without swapping out the whole unit. Scale buildup is worth asking about directly, since it affects how well the unit heats water over time and how long it lasts. A contractor can run the error code the unit displays to identify which part needs attention.
