Plano weather is hard on a water heater in its own way
Collin County gets cold enough that your water heater works harder from November through March. Winter nights average 36°F from December through February. Incoming water is colder, so the tank runs longer to make up the difference. The heating element or burner assembly takes the load, and so does the thermostat. Those are the parts that wear first.
Power matters too. Collin County has logged 22 winter storms and 86 damaging wind events over the past ten years, and a third of Texas households lost power for 24 hours or more at some point in 2024. Most electric water heaters turn back on by themselves once power returns. A gas unit with a standing pilot never loses it at all. But a tank that was already struggling before the outage, with a weak element or a failing thermostat, often does not come back the same. That is when homeowners notice lukewarm water or a tank that will not heat at all.

A new water heater would cut about $290 a year off hot water for a typical Texas 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 starting to fail. Water heaters corrode over years of holding heated water, and once the tank wall is breached, no fitting or valve tightening will stop it. It can also be a loose drain valve or a fitting where a pipe connects, and those are worth checking before you assume the worst. A leak from the bottom while the tank is still full usually means the tank is done and needs replacing.
- 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, it shuts gas to the pilot even though the flame is fine. A dirty pilot orifice or a draft in the area can also blow the flame out. A standing pilot uses no electricity, so a power outage is not the cause here, but a contractor can test the thermocouple and replace it if that is the problem.
- Can a tankless water heater be repaired?
- Yes, most tankless water heater problems are repairable. Issues like a failed igniter, a clogged inlet filter, mineral buildup on the heat exchanger, or an error code from a sensor can usually be fixed without replacing the unit. A licensed contractor can run the diagnostics built into the unit to find which part is causing the problem and price the repair for your specific system.
