Denton County water heaters lose power more than they lose heat
Water heaters here rarely have to fight the cold the way a furnace does. Winter nights average 36°F, mild enough that the tank itself is not under much strain. What gets to a water heater in Denton County is the power going out from under it.
Across Texas, a third of households were without power for at least 24 hours in 2024, and this area has logged 20 winter storms and 115 damaging wind events over the past ten years. A gas water heater with a standing pilot will keep making hot water through an outage. One with electronic ignition or a heat pump unit will not, and it needs the power back before it lights again. If your water heater is cold after the lights come back on, that is often the reason.

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 of the time this means the tank itself has rusted through and is failing. Water heater tanks corrode from the inside over years of use, and once the metal gives way, no fitting or seal will stop the leak. It can also be the drain valve or a fitting that has loosened rather than the tank, and that part can be replaced. A contractor can tell you which one it is by drying the area and watching where the water comes from first.
- Why won't the pilot light on my water heater stay lit?
- The most common cause is a worn thermocouple, the small part that senses the pilot flame and tells the gas valve to stay open. When it fails, the valve shuts the gas off even though the pilot is lit, so the flame goes out soon after you release it. 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 that is the problem.
- Can a tankless water heater be repaired?
- Yes, most tankless water heater problems are repairable. Common issues include a failed igniter, a clogged inlet filter, mineral buildup on the heat exchanger, or an error code pointing to a sensor. A contractor can read the unit's fault code and know which part to check first. Whether it makes more sense to repair or replace depends on the age of the unit and what's wrong with it, which is something a contractor can assess in person.
