Recommended unit for Molalla
Given Oregon’s mild marine west of cascades, cold semi-arid east climate and mixed water heating, heat-pump (hybrid) is the sensible default for most Molalla 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.
