Ten months of the year, your water heater doesn't get a break
Centralia asks a lot of a water heater. Homes here need heat, and hot water, from September through June, which means ten months of steady use instead of a few months of heavy demand and a long rest. Winter nights average 31°F from December through February, and cold ground water takes more energy to bring up to temperature, so the unit works harder on the coldest nights of the year, for most of the year.
A new water heater installed here has to be sized for your household, not just swapped in at the same size as the old one. The federal efficiency minimum isn't one number. It's set by a formula based on the tank's rated volume, and that formula changes depending on how the household draws hot water, so two homes with different needs can be held to different minimums even with the same size tank. Getting that sizing right at installation is what keeps the unit running the way it should through all ten months.

A heat pump water heater would save about $280 a year to run in Washington compared with an electric water heater.

- How do I know it's time to replace my water heater?
- The clearest sign is water pooling around the base of the tank. That means it's leaking, and a leaking tank doesn't get fixed, it gets replaced. Rust-colored water, a tank that's making rumbling or popping noises, or water that never gets quite as hot as it used to are also signs the tank is failing inside. If you're seeing any of these, it's worth having a contractor look at it before it fails outright and floods the area around it.
- Should I switch to a tankless water heater?
- It depends on what you want out of it, not on whether your current tank is old. A tankless unit heats water only when you're using it, so you don't run out partway through a shower, and it takes up a lot less space than a tank. It usually costs more upfront and may need changes to your gas line, venting, or electrical to be installed. A contractor can look at your home and tell you what switching would actually involve for your setup.
- What changes when you install a tankless water heater?
- The biggest change is that you stop storing hot water and start heating it on demand, as it flows through the unit. That means no more running out of hot water, but it also means the unit needs enough gas flow or electrical capacity to heat water fast enough for your fixtures. Venting is different too, tankless units typically vent through the wall rather than up through the roof. Because the unit mounts on the wall instead of sitting on the floor, it also frees up the space your old tank used to take up.
