McAlester winters put weight on a water heater
From November through April, six months a year, your water heater works harder. Winter nights average 32°F, and cold ground water takes more energy to heat before it reaches the tap.
Pittsburg County has seen 9 winter storms and 61 damaging wind events over the past ten years, and a quarter of Oklahoma households lost power for 24 hours or more in 2024. A gas water heater with a standing pilot will keep working through an outage. One that relies on electronic ignition will not fire until the power comes back. New units also have to meet a federal minimum efficiency rule that scales with tank size, so the right minimum for your household depends on the size you need, not just the type.

A heat pump water heater would save about $250 a year to run in Oklahoma compared with an electric water heater.

- How do I know it's time to replace my water heater?
- The clearest sign is water around the base of the tank. That usually means the tank itself has started to fail on the inside, and once that happens it does not get better on its own. Water that stays lukewarm no matter how you adjust the thermostat, or that runs out fast, is another sign the tank is wearing down. Rust colored water from the hot side, or a rumbling sound from the tank when it heats, points the same way. Most storage water heaters last a limited number of years, so if yours is old and starting to show any of these signs, a contractor can tell you whether it is worth repairing or time to replace it.
- Should I switch to a tankless water heater?
- It depends on what you want from your hot water and what your home can support. A tankless unit heats water as it passes through rather than storing a tank of it, so you do not run out of hot water partway through a long shower or back to back loads of laundry. It also takes up much less space than a tank. Switching usually means changes to the gas line, venting, or electrical circuit feeding the unit, since tankless heaters draw more power at the moment they fire than a tank does. A contractor can look at your home and tell you what that would involve for your setup.
- What changes when you install a tankless water heater?
- The unit itself is smaller, but what feeds it usually has to get bigger. A gas fired tankless heater needs a larger gas line than a tank because it has to heat water fast rather than gradually over time. It also needs its own venting, sized and routed differently than a tank's vent. An electric tankless heater draws enough power that it often needs a dedicated, heavier circuit than the one that served the tank. None of this is guesswork specific to your house. A contractor checks the gas line, the vent path, and the electrical panel before installing, and sizes each one to the new unit.
