Ten months of hard use, and winters that push past freezing
Your water heater works from September through June here, close to year round. Winter nights average 14°F from December through February, and the colder the water coming in, the harder the unit runs to bring it up to temperature. That extra work falls on the heating element or the burner, and on the thermostat that keeps calling for more heat.
Big Horn County sees hard weather. Ten years of records show 84 winter storms and 91 damaging wind events, and storms like that take down power lines. When the power goes out, an electric water heater stops heating until it's back, and you will notice cold water first, before anything else in the house tells you power is gone.

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, and once that happens the tank can't be patched or sealed. Sediment builds up at the bottom of the tank over years, and it corrodes the steel from the inside until it gives way. A leak could also come from the drain valve or a fitting near the bottom, which a contractor can replace without touching the tank. If the water is coming from the tank body, the water heater needs to be replaced.
- Why won't the pilot light on my water heater stay lit?
- The most common cause is a worn thermocouple, the small sensor that sits in the pilot flame and tells the gas valve it's safe to stay open. When it wears out, it can't hold that signal and the gas valve shuts the pilot down. A dirty pilot orifice or a draft in the area can also blow the flame out. A contractor can test the thermocouple and replace it if it's reading weak.
- Can a tankless water heater be repaired?
- Yes, most problems with a tankless unit are repairable. Igniters, flow sensors, and heat exchangers can all be replaced without swapping out the whole unit. Mineral buildup from hard water is one of the most common issues, and flushing the unit often restores it. A contractor can check the error code the unit is showing to find out what's actually failing.
