Customer Reviews for Bosch 4 Gal. Mini-Tank Electric Water Heater (3-Pack)

It does provide hot water, but the flow rate has been reduced by a factor of 3. Had I known this I would not have purchased it.

Compact and easy to install. Water heats up quickly. Only issue so far is the off/temp control knob is hard to change.

The Bosch Tronic 3000T four gallon water heater has given flawless performance for the last six months. I believe that is long enough for me to now write a review. Our main water heater is in the garage, so when a little bit of hot water for hand washing or rinsing a dish was desired at the kitchen sink, the task would be long finished before any hot water ever made it to the sink. We installed the Bosch water heater in a "trash can" cabinet next to the sink. The cabinet was large enough for two large trash cans. We installed the heater and still have room for smaller regular and recycle cans. On a winter day (or any day for that matter) it is now such a luxury being able to turn on the tap and have perfect hot water instantly. There is a detente mid-way on the thermostat knob. We turned the temp higher than the detente, and then backed it down to just touching the detente. Perfect water temperature for us every time. And if we need more hot water for the dishwasher or other uses, the Bosch delivers all the hot water we need until the hot water from the main water heater arrives. Not only do I like the instant hot water, but I am still getting warm smiles from my wife every time she uses the hot water, too. As a husband, this was a great way for me to get many points.

Used this one as a booster water heater since my main water heater is in my garage at the other end of the house; who designs these systems? Easy to install and gives nearly instant hot water in my master bath. Easy to install and works great.

Love it! EZ installation. Provides all we need at the kitchen sink

Absolutely does what it is suppose to. Holds hot water overnight even when turned off

So far it has been great. Haven't had it long enough to rate properly

easy to install, made life better

Had an issue with water not getting hot for sometimes up to a minute depending on time of year. Now less than 3 seconds! Should save on my water bills. Great product and easy install.

Easy to install. Enjoying instant hot water.

Only installed last week but so far works great. Time will tell

Easy to install and Work well.satisfied!

One line in, one line out, fill it up, plug it in, and hand-freezing cold water turned into glorious warmth. No delay in the hot water since it's right there under the sink.

Performed as stated. Instant hot water

The water heater works excellent and is very is to install

I love this little water heater. My hot water heaters are both upstairs. I had to run the water at my kitchen sink for over 2 minutes before to he water was hot. Maddening!!! Now I have instant hot water when I need it with a constant reservoir of hot water. Heaven!!

I bought one of these, paid to have it installed snd within weeks it leaked at the the pressure relief valve. Replaced it, again paying to have it installed. HD took the first unit back, no problem. I hope the second unit lasts.

Went thru all the work of installing and the heater doesn’t even work! Does the manufacturer cover labor costs ?

Works great, saves $$

Works perfectly and is a great solution to obtaining hot water instantly at the kitchen tap. Now we don't have to run the water for five minutes to get warm water, at best. The tank was easy to install and I also installed a discharge hose off the pressure relief nozzle back to the sink drain just in case of any pressure relief discharges. I plan to drain the tank every six months and examine the anode to ensure proper operation. Took up some room under the kitchen sink but it needed to be cleared out anyway. I also have leak sensors under the sink just in case of any future issues with connections, peace of mind, etc. Would NOT recommend the 2 gallon and the 4 gallon is perfect. Didn't opt for the 8 gallon since it was larger and had to be hardwired. You can get scalding hot water if you want but can adjust accordingly at the faucet or at the tank itself. I'm considering ordering another tank for the outside kitchen where I have the same issue with taking too long to get warm and wasting water. Highly recommend!
