What a Corvallis water heater is up against
Water heaters here run nine months of the year, October through June, and on winter nights that average 35°F the incoming water is cold too. A new unit needs to be sized for that stretch, not just for a mild day in summer.
Oregon saw 20% of households lose power for at least 24 hours in 2024, and Benton County has recorded two damaging wind events over the past ten years. A gas water heater with a standing pilot keeps working through an outage. One with electronic ignition will not light again until the power is back. That is worth thinking about when choosing which kind to install.
The federal minimum efficiency for a new storage water heater is not a single number. It is set by a formula tied to the tank's rated volume, applied differently depending on how a household draws hot water. Two tanks of the same type in different sizes can carry different minimums, which matters when deciding what size to install.

A heat pump water heater would save about $390 a year to run in Oregon compared with an electric water heater.

- How do I know it's time to replace my water heater?
- How it's failing tells you most of what you need to know. Rust colored water from the hot tap, water pooled at the base of the tank, or a pilot that won't stay lit are signs the tank itself is going, not just a part on it. A tank that's rumbling or not keeping up with hot water is often coated with sediment inside, and that gets worse, not better. If the problem is a thermostat or heating element and the tank isn't leaking or rusting, a contractor can usually fix that instead of replacing the whole unit.
- Should I switch to a tankless water heater?
- It depends on what you want out of it, not on any rule that says one is better. A tankless unit heats water as it flows, so you don't run out partway through back to back showers the way you can with a tank. It also takes up less space than a tank. Against that, a tankless unit needs venting and a gas supply sized for it, and in some homes that means real work to install one where a tank sat before. A contractor can look at your gas line, venting, and where the unit would go and tell you what switching actually involves in your house.
- What changes when you install a tankless water heater?
- The biggest change is that hot water stops being something you can run out of, since the unit heats it as it flows instead of storing a tankful. That also means a smaller footprint on the wall or in the mechanical room, since there's no tank to make room for. It usually means new venting, since tankless units vent differently than a storage tank and the existing vent often isn't sized right for one. Some homes also need the gas line upsized, since a tankless unit calls for more gas flow in the moment than a tank does. A contractor can check your existing gas line and venting to see what the switch requires in your specific house.
