Cold groundwater and hard winters wear on your water heater in Burlington
Your water heater works harder here than the label assumes. Groundwater coming into the tank is cold most of the year, since homes need heat from October through May, and the unit has to raise that temperature further to get you hot water. That extra work falls on the heating element or the burner, and on the thermostat that controls it.
Burlington has had 17 winter storms and 88 damaging wind events in the past ten years, and across Iowa, 15% of households lost power for 24 hours or more in 2024. When the power drops in the middle of winter, an electric water heater stops heating until it comes back on, and a tank full of cold water takes a while to recover. If your water heater has a pilot light, it will usually stay lit through an outage, but the thermostat on either type can fail after years of temperature swings, and that shows up as water that runs cold or never quite gets hot.

A new water heater would cut about $50 a year off hot water for a typical Iowa 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 tank itself has likely rusted through from the inside and is starting to fail. Water heaters corrode from the inside out over years of use, and once the tank wall is breached, no fitting or valve tightening will stop it. A leak lower down on the tank body usually means replacement, not repair. If the water is coming from a fitting, the drain valve, or the temperature and pressure relief valve instead of the tank itself, a contractor can often fix that without replacing the whole unit, so it is worth having someone check exactly where the water is coming from before assuming the worst.
- Why won't the pilot light on my water heater stay lit?
- The most common cause is a worn thermocouple, the small sensor that tells the gas valve the pilot is burning. When it wears out or sits out of position, the gas valve shuts off the pilot as a safety measure even though the flame was fine. A dirty pilot orifice or a draft in the area can also blow the flame out repeatedly. A contractor can test the thermocouple and clean or adjust the pilot assembly to find out which one is causing it.
- Can a tankless water heater be repaired?
- Yes, most tankless water heater problems are repairable. Issues like a clogged inlet filter, mineral buildup on the heat exchanger, a failed igniter, or an error code from a sensor are things a contractor can diagnose and fix without replacing the unit. Tankless units do need periodic descaling to prevent buildup, so a repair sometimes turns into a maintenance conversation as well.
