Answer This Question
A:Â PrestoneAntifreeze, If by "owner" you are referring to the primary hot water unit, this will be fine. We refer to this as a booster application. You will simply run the primary hot water unit's Hot line into the ES4's Cold intake.

Q:Can this be used for a shower if paired with a conventional whole house gas water heater? I'd like instant hot water for the shower then when this runs out of its 8 gallons, the gas heated water would arrive.

Answer This Question
A:Â John, Yes, that is a common application. Just run your Hot line from your primary hot water source into the Cold intake of this unit and then run the Hot line from this unit to your shower. Place this unit as close to your shower as possible to reduce any lag time.

Wall mounted under my kitchen in the basement so we didn’t have to run the water so long for hot water. Also feeds the dish washer and laundry. Easy to install, works great.

Response from Bosch ThermotechnologyJun 3, 2020
Jim, That's what I did in my basement for our master bath. Unfinished basements are great. Some people will place this in their attic, too. They just need to be extra cautious of connecting the pressure relief valve to a drain line. It is great to experience "Hot Water Now!" We are happy you are enjoying your Bosch model ES7 water heater. Our motto is "Invented for Life" and we are glad to be a part of yours.

I have this installed in series after my tankless water heater. This provides a buffer of hot water to prevent any sort of cold water sandwich between hot water uses since the tankless heaters can take a moment to activate when flow begins. It also is important to me because when low-usages such as efficient washing machines and some dishwashers use hot water it's at such a low rate that it would not trigger the tankless' minimum flow rate. Between the two of them I feel I have a combination that results in endless hot water, immediate use when needed, and energy efficiency. Please note that this is the size to get if you plan to use your water heater in a similar capacity as the smaller tanks have 1/2" fittings that would likely limit your flow rates for whole-house solutions. This one is 3/4" and requires a hard-wired connection.

It took an out $200 worth of parts, but it works. Not quite as simple as it seems, but after a few minutes I get a hot shower. Guess that’s all I really wanted.

Love this water heater so far! Installed for 10 days in my cabin and could not be happier. Dial that lowers water temp works great; if you want very hot so that you can extend your hot water at your point of use.. bingo! I conserve water and have a shut off valve at my shower head so 7 gals. is plenty for me to take a full military shower and wash my hair! Anyone conserving water should install an on/off valve at shower head anyway. If you like to take long hot showers this heater would NOT BE FOR YOU.
This unit is supposed to be hard wired. I attached/wired a 12 guage, 6 foot cord to it so that I could plug or unplug it. I have experience so the installation was easy for me, otherwise you should consult a professional for the wiring and plumbing. The heater produces exactly like it says its supposed to and I would give it 10 stars if I could.

I finally have hot water in my kitchen what's truly fantastic is that I can finally use my dishwasher after 4 years and I can now actually get the dishes clean. I turn on the faucet and I have hot water immediately What's not to love about that.
