Which should you pick?
- Tank: lowest upfront cost, simplest swap, good if your current tank is the right size.
- Tankless: endless hot water and less space, but gas line and venting upgrades can double the price.
- Heat pump: lowest running cost for electric homes, especially with rebates.

Costs across Portland neighborhoods
We haven't found reliable published prices broken down by Portland neighborhood, so we don't list made-up numbers per area. What does change from one part of town to another is the age and type of housing, which drives how much work a job needs.
- Older homes (much of Southeast and Northeast): may need new seismic strapping, expansion tank or venting to meet current code.
- Basement or crawl-space installs: harder access adds labor time.
- Condos and apartments: tight closets and building rules can limit tankless options.
