Eight months of hard use on your water heater
From October through May, your water heater is working against cold groundwater for eight months straight. On the winter nights here, when temperatures average 12°F, the incoming water is cold enough that the burner or element has to run longer to bring it up to temperature. That extra runtime wears on the heating element, the thermostat, and the gas valve faster than it would in a milder climate.
Parker has seen 36 winter storms over the past ten years. When the power goes out during one, an electric water heater stops heating until it comes back on, and most units pick up again on their own once power is restored. If yours does not, or the water stays cold after the power returns, something inside failed rather than just the outage.

A new water heater would cut about $280 a year off hot water for a typical South Dakota home.
Estimates for a typical South Dakota home, compared with an older unit built to the federal minimum, from EIA household energy data and South Dakota fuel prices. Your home will differ.
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 cause is the tank itself, corroded through from the inside after years of holding water. Once a steel tank rusts through, no seal or fitting will stop the leak, and the tank needs to be replaced. Water at the bottom can also come from a loose drain valve, a failing temperature and pressure relief valve, or fittings that have loosened over time, and those can often be repaired. A contractor can tell within a few minutes which one you have.
- Why won't the pilot light on my water heater stay lit?
- Most of the time this means the thermocouple, the small sensor next to the pilot flame, has worn out and no longer tells the gas valve the flame is lit. When that happens, the valve shuts off the gas as a safety measure, even though the pilot lit fine a moment ago. A dirty pilot orifice or a draft pulling the flame away from the sensor can cause the same thing. A standing pilot does not run on electricity, so a power outage is never the reason.
- Can a tankless water heater be repaired?
- Yes, most tankless water heater problems are repairable. Mineral buildup on the heat exchanger is common and is cleared by flushing the unit, especially important since it runs 8 months of heating season here alongside hot water demand all year. Igniters, flow sensors, and venting can also fail on their own and get replaced without swapping the whole unit. A contractor can check the error code on the display and tell you which part is at fault.
