Leaking

Only 2 1/2 years old and started leaking. Called customer service, they said you must replace the Anode rod every year, or warranty is void.

Didn’t work!

It just didn’t work. Possibly the computer board? Lowes is now out of stock so we really don’t know if it would be a good option.

Very easy to install! No issues at all! Everything went as planned!!

Nice product...well-designed and compact. Used this for an efficiency apartment. Requires direct wiring, and 3/4" NPT water connections.

So far it works well. Easy to install. Does what it's supposed to do.

Bosch 7 gal water heater has worked out well. It was easy to install and set up. We are pleased with this product and would recommend it.

Great service fast delivery!

May just be a glitch, but it did not work right out of the box. Went thru a lot of work to install it, plugged it in, and nothing. Will be returning it when I can get a plumber back out here to take it out again. I will probably buy the same one, it must be a fluke - right? An expensive fluke.

Great master bath instant hot water

We plumbed this ES8 in-line with the main water heater, so that all of our master bath hot water is supported. Main heater is opposite side of the house. Has been installed since 2020, used daily, our water is not overly hard, and, in general, the main water heater replenishes it so it does not work too hard. We like the near instant hot water. Our electrical inspector required the unit to be on a dedicated 20A circuit even though it is only 80% of a 15A circuit. We also installed a mixing valve to limit the main water heater usage...which had a backflow preventer...which required a local expansion tank, so you might want to consider those items. It was installed vertically, for the max gallons, in a vanity cabinet. Takes up about half the cabinet and still leaves room for the sink drain, but just barely.

I've been using these Bosch water heaters for over twenty years and am not aware of an element burning out yet. Apparently it is hard to beat a titanium element.

We've only had it for about a month, so I cant speak to reliability or longevity, but so far it has worked great, we've had no problem's with it. In our application, it's used as a hot water "booster" for a kitchen sink that's a 90 feet from the water heater.

This is my second Bosch heater. Previous heater lasted almost 8 years. So the installation was easy since the pumping was already in place.Works well for a single point. Would recommend placing the heater in a heater pan in case of any leaks. This will protect the cabinet floor.

Perfect for my application. Works great, small footprint.

Works as specified. Installed under kitchen cabinet.

These water heaters don’t seem to last

This was purchased for use in a out building shop / garage with a restroom. The 7 gallon size is great for using the sink and any hot water needed while in the shop and was even great when we had to shut of the water in the house for a day while doing some plumbing. I did not want a 220v water heater in an all electric house, and yet did not want a small unit that was just enough for handwashing. This unit works perfect for this situation. Also having the safety valve and anode rod, like a large unit is awesome, especially when on well water. It is installed just like a large unit, with a small "point of use" expansion valve.

Good Brand...but

Purchased similar item on the past and was very satisfied with it so I bought another. Was sent a used item. HD nonotorious for sending used and returned items.

7 gal lasted entire shower and shampoo. 4 gal turned cold real fast i. Under 4 min

I bought this water heater for my camper. Very easy to install and plenty of hot water now to shower.

Leaked after 3 years old.

Leaked after 3 years. 6 year warranty on tank not leaking. I will have to see if they will replace it.
