Rheem Performance 8 kW Tankless Electric Water Heater
Community verdict
The Rheem 8 kW Tankless Electric Water Heater is generally regarded as a functional point-of-use solution for low-demand fixtures like single sinks. Buyers appreciate its compact footprint and straightforward installation process when properly configured with adequate electrical service. However, reviewers frequently report that the limited flow rate makes it unsuitable for whole-home use or showers, particularly in regions with cold incoming groundwater.

Painless to Install, Works Great... four months ago and the unit is performing flawlessly! Zero leaks.
I bought a "used, acceptable" condition rtex 08 from Amazon over 4 years ago now. Raises temps about 60 degrees on avg in my experience...
it works well enough for a single sink in Northern Oregon once a flow restrictor is installed on the output. There is NO WAY this would run a shower
Purchased and installed one, it was faulty upon installation... Tenant constantly complained about insufficient hot water, then it caught fire...
