What a new water heater faces in Tillamook County
Homes here call for heat September through June, ten months of the year, with winter nights averaging 35°F from December through February. A water heater in this county gets little rest.
The federal minimum efficiency it has to meet is not one number. It is set by a formula tied to the tank's rated volume, worked out separately across four draw patterns, so two tanks of the same type can face different minimums depending on their size. Power loss is worth planning for too. Oregon households went at least 24 hours without power in 2024 in 20% of cases, and the county has recorded six damaging wind events over the past ten years.

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 usually means the tank itself is failing and won't stop. Rusty hot water, a pilot or igniter that won't hold, or hot water that runs out faster than it used to are all signs the tank is near the end of its life. If yours is giving you any of these signs, it's worth having a contractor look at it before it fails outright and floods the space around it.
- Should I switch to a tankless water heater?
- It depends on what you want out of it, not just the type. A tankless unit heats water on demand, so you don't run out partway through back to back showers the way you can with a tank. It also takes up much less space and doesn't hold standing water that can leak. Against that, a tankless unit usually needs a larger gas line or a dedicated electrical circuit, and venting is different from a tank. A contractor can tell you what your house would need to make the switch.
- What changes when you install a tankless water heater?
- The unit itself is smaller and mounts on a wall instead of sitting on the floor, so where it goes in the house often changes. Gas tankless units need venting sized for that unit, which is different from tank venting, and many need a larger gas line to deliver enough fuel on demand. Electric tankless units draw a lot of current at once, so the electrical circuit feeding it has to be sized for that. A contractor will look at your gas line, venting, and electrical setup before quoting the switch.
