What a Stillwater winter asks of a new water heater
Heat runs October through April here, seven months of the year, with winter nights averaging 28°F. A new water heater sits through that same stretch of cold, and the tank you choose has to meet the federal minimum efficiency set for its size, since the standard is not one number but a separate figure for each tank volume.
Power matters too. A quarter of Oklahoma households lost power for 24 hours or more in 2024, and Payne County has logged 7 winter storms and 83 damaging wind events over the past ten years. A gas water heater with a standing pilot keeps making hot water when the power goes out. One with electric ignition will not, though it comes back on by itself once power returns.

- How do I know it's time to replace my water heater?
- Look at the age first. Most tank water heaters last about a decade, and past that point the tank itself starts to wear from the inside. Rusty water from the hot tap, a tank that's making popping or rumbling sounds, or water pooling around the base are all signs the tank is failing rather than something you can repair. If your water heater loses power in a storm and doesn't reheat once power is back, that points to a problem with the unit itself, not just the outage. A leaking tank won't get better, so once you see water at the base it's time to replace it rather than wait.
- Should I switch to a tankless water heater?
- It depends on what you want out of your hot water, not on your old tank failing. A tankless unit heats water as you use it instead of storing it, so you don't run out during a long shower, and it doesn't sit there holding heat when nobody's using hot water. It also takes up less space than a tank. What it won't do is fix low water pressure or hard water problems, since those come from the plumbing and the water itself, not the heater. A contractor can look at your gas line, venting, and how much hot water your household actually uses at once to tell you whether tankless makes sense for your house.
- What changes when you install a tankless water heater?
- The biggest change is that hot water gets made on demand instead of pulled from a tank that's already heated and waiting. That means a gas tankless unit usually needs a larger gas line than your old tank did, since it has to heat water fast rather than slowly over time. Venting is different too. Tankless units vent through pipe sized for their own output, which often means new venting has to be run rather than reusing what's there. The unit itself mounts on a wall instead of sitting on the floor, which frees up space but means the installation involves more than swapping one box for another.
