Ten months of heating demand, and power that doesn't always stay out
Homes here need heat from September through June, 10 months a year, and a water heater works alongside that system through all of it. Winter nights average 33°F from December through February, so the water coming into the tank runs cold for a good stretch of the year.
Power is the other piece. In Oregon, 20% of households went at least 24 hours without power in 2024, and Marion County has recorded six winter storms and two damaging wind events over the past ten years. A gas water heater with a standing pilot keeps heating through an outage. One with electronic ignition, or an electric unit, will not until power is back, though most come back on their own once it is. Whatever gets installed has to meet the federal minimum efficiency for its type, a figure set separately depending on the tank's size.

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?
- Look at the age first. Tank water heaters have a working life, and once yours is old enough, a repair is often just delaying the same decision a year or two down the road. Rust colored water from the hot tap, a tank that's damp or rusted at the base, or water pooling underneath are signs the tank itself is failing, not something a part replacement fixes. If it's making rumbling or popping sounds, sediment has built up on the bottom, and that can shorten what's left of its life. A contractor can check the tank and the anode rod and tell you whether you're looking at a repair or a replacement.
- Should I switch to a tankless water heater?
- It depends on what you want from it, not on your current heater being old or broken. Tankless units heat water on demand instead of storing it, so you don't run out of hot water partway through back to back showers or a shower and a load of laundry at the same time. They also tend to last longer than tank units. What they don't do is deliver more hot water per minute than the unit is rated for, so a house with several fixtures running at once may need a larger unit than a house with one bathroom. A contractor can look at your fixture count and gas or electric supply and tell you whether a tankless unit fits your house the way it's plumbed now.
- What changes when you install a tankless water heater?
- The biggest change is that hot water is made as you use it instead of stored ahead of time, so there's no tank sitting full and waiting. That means no standby heat loss from a tank cooling down between uses. It also means the unit has a maximum flow rate, so if you're used to running the dishwasher and a shower at once, that's worth checking against the new unit's rating. Gas fired tankless units usually need a larger gas line and a different vent than a tank unit, and electric units often need more electrical capacity than what fed the old tank. A contractor can tell you what your gas line, vent, or electrical panel would need to support the switch.
