Bosch ES series is a huge step forward in technical development but such a bad taste has been left by former products and Bosch technical support that few plumbers will recommend one regardless of what improvements are made today or tomorrow. This model still has the same potential for gas valve failure that goes back to their 250 SX series that if condensation or rain is not caught before it reaches the gas valve, the valve must be replaced and is nearly 3X the cost of their competitors. Performance is as stated but if your incoming water temperature is not 65 F then expect far less performance. Your homes gas piping and water piping must be taken into account before considering this and the cost of a single wall stainless steel vent system must be calculated into the total cost. Bosch also requires a propritory roof termination kit that if not installed, voids your warranty and this too adds to the total cost.
As a licensed plumber contractor in Ca and a former authorized service provider I had never in all the years of servicing Bosch, seen a correctly installed Bosch tankless. It really doesn’t take that much effort to read the instructions and follow them. Of all the various makes and models we have installed in nearly 30 years, I never once had a failure or problem due to my own installations. Bosch service calls sometimes totaled more than 35 per week on new installations alone by home owners, handymen and plumbers. If properly installed, they are perfectly good water heaters. Tthey do have the best and most robust heat exchangers of all brands, this particular models control board is the most advanced and user friendly of all but only to service providers. The only downside is the limited access to Bosch technical support too and if not installed to the letter, Bosch may and have voided warranties in the past. Due diligence goes a long ways and emotional reviews only blur accurate information for those seeking answers. Bosch is making the effort to improve product and service and I will give them that…
