What a McMinnville water heater has to handle
Yamhill County homes run their heat October through June, nine months of the year, and the water heater works that whole stretch too. Winter nights average 35°F from December through February, cold enough that incoming water is cold when it reaches the tank.
The federal minimum efficiency for a new storage water heater isn't one number. It's a formula tied to the tank's rated volume, applied separately across four draw patterns, so two tanks of different sizes answer to different minimums. A licensed installer checks the new unit against the standard that applies to its size. Worth asking too is how it comes back on after the power goes out, since 20% of Oregon households went at least 24 hours without power in 2024.

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?
- The clearest sign is water pooling around the base of the tank, since that means the tank itself has failed and it will not stop. Water that comes out rusty or with a metallic smell, even after you run the hot side for a while, points to corrosion inside the tank. A unit that used to keep up and now runs out of hot water partway through a shower has lost capacity it will not get back. Age matters too. A contractor can check the date on the tank's label and tell you where it stands against a typical lifespan, and whether a repair is worth it or just a short delay before something else on it fails.
- Should I switch to a tankless water heater?
- It depends on what you want out of your hot water and what your home can support, not just on the water heater itself. A tankless unit heats water on demand instead of storing it, so you do not run out partway through back-to-back showers or a full load of dishes plus a shower. It also stops the standby loss you get with a tank, since a tank keeps a full volume of water hot around the clock whether you are using it or not. But a tankless install often means new gas line sizing or a larger electrical circuit, and venting has to be rated for the higher heat, so a contractor needs to look at your home before you know if the switch is straightforward or a bigger job.
- What changes when you install a tankless water heater?
- The unit itself is much smaller, so it usually goes on a wall instead of taking up floor space. Gas-fired tankless units draw a heavier gas load in short bursts than a tank does, so the gas line often needs to be resized to feed it properly. Venting changes too, since tankless units typically vent through PVC or stainless steel rated for their higher exhaust heat rather than the metal flue a tank uses. And because there is no tank storing hot water, the unit turns on and heats water the moment you open a hot tap, rather than pulling from what is already sitting hot and waiting.
