Recommended unit for Kelso
Given Washington’s cool marine / temperate climate and electric water heating, heat-pump (hybrid) is the sensible default for most Kelso homes. Winter inlet water runs cold here, so recovery rate matters — size up a tankless or favor a high-recovery tank. A pro can confirm the right size and fuel for your home.

Older homes (median built 1961) may need plumbing or electrical upgrades, and installing seismic strapping is mandatory in Washington. Permit fees and expansion tank requirements also add to the total. Inlet water is cold year-round, which can affect heat pump efficiency, but modern units are designed for cooler climates.
