Eight months of heating season puts real demand on a water heater
Carson City homes need heat from October through May, eight months a year, with winter nights averaging 25°F from December through February. A water heater here is working through the same cold months as the furnace, drawing on the same incoming water and the same power supply.
Power does not always stay on. Across Nevada, 13% of households lost power for 24 hours or more in 2024, and this county has logged 221 winter storms and 287 damaging wind events over the past ten years. Most water heaters come back on by themselves once power returns, so that is one less thing to worry about after an outage. Whatever size you choose, it has to meet the federal minimum efficiency for storage water heaters, and that minimum is set by a formula based on the tank's rated volume, not one flat number, so a larger tank and a smaller one are held to different standards.

- How do I know it's time to replace my water heater?
- Check the data plate for the age of your tank first, since older units are the most likely to fail without warning. Rust-colored hot water, a tank that's damp or rusting at the base, or water pooling underneath all mean the tank itself is failing, and there's no repair for that. If it's still heating but running out fast or taking longer to recover, that can sometimes be fixed. A leaking tank always means replacement, not repair.
- Should I switch to a tankless water heater?
- It depends on what you want, not on whether your current tank is failing. A tankless unit heats water as it flows through instead of storing it, so you don't run out partway through back to back showers. It won't deliver more gallons per minute than the unit and gas line are sized for, so a house that runs several fixtures at once needs a unit sized for that load. A contractor can look at your gas line, venting, and hot water use and tell you whether tankless fits your house.
- What changes when you install a tankless water heater?
- Hot water stops running out. A tank heater stores a set number of gallons, and once that's used up you wait for it to reheat. A tankless unit heats water on demand, so supply matches how long you run the tap rather than how much was stored ahead of time. Because the burner fires in shorter, harder bursts, gas tankless units often need a larger gas line and different venting than a tank did. It also takes up much less floor or closet space since there's no tank to house.
