Nephi winters put weight on a water heater
Groundwater coming into your house is cold from October through May, and your water heater has to work harder to make up the difference. That extra work falls on the heating element or the burner, and on the thermostat that tells it when to fire. Over time that shows up as water that never gets quite hot, or a tank that takes longer to recover after a shower.
Winter nights averaging 20°F also mean a higher chance the power goes out. Utah households saw outages of a day or longer last year, and Juab County has logged 48 damaging wind events over the past ten years. A gas water heater with a standing pilot will keep working through that. One with electric ignition will not relight on its own, and you will notice cold water until it does.

A new water heater would cut about $80 a year off hot water for a typical Utah 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?
- Most often the tank itself has rusted through from the inside and is cracked. Water heaters hold sediment at the bottom of the tank over the years, and that sediment eats away at the lining until the steel underneath gives way. A leak from the bottom almost always means the tank needs to be replaced, not repaired, since a cracked tank cannot be sealed. Sometimes the leak is coming from a fitting or the drain valve instead of the tank, and a contractor can tell the difference quickly by drying the area and watching where the water shows up again.
- Why won't the pilot light on my water heater stay lit?
- The most common cause is a worn thermocouple or flame sensor, the part that tells the gas valve the pilot is burning. When it wears out or gets coated in soot, it reads the flame as out and shuts the gas off even though the pilot is lit. A weak gas supply or a draft blowing across the pilot can cause the same thing. A dirty pilot orifice is another possibility, and cleaning or replacing the right part usually solves it for good.
- Can a tankless water heater be repaired?
- Yes, most problems with a tankless unit are repairable. The heat exchanger, the igniter, the flow sensor and the venting are the parts that tend to fail, and each can be replaced on its own without replacing the whole unit. Mineral buildup inside the heat exchanger is common too, especially with hard water, and flushing the unit on a regular schedule prevents a lot of the problems that would otherwise call for a repair. A contractor can tell you whether the fix is worth it or whether the unit has reached the point where replacement makes more sense.
