Bosch Thermotechnology ES4 Reviews & Ratings

My third unit
By Mike D.

Review Posted 08/08/2019
This is my second unit, My first with the Bosch name. My last one was identical, but an Ariston. This choice made replacement very easy by me, the homeowner. No plumber needed since it was no more difficult then changing the zinc rod every year.
