Too small for a shower. sink maybe okay.

After buying several models, Bosch doesn't make anything tankless that works for more than a sink. For a cabin shower? Don't even think about it.

Pros
  • Rough Plumbing
Cons
  • Limited warranty period compared to traditional tanks

Pros
  • Sink in shop.
Cons
  • Does not get water hot. It’s barely warm, even when turned on high. Very disappointed, to say the least.

The water doesn’t get hot enough to wash your hands

Used for a kitchen sink at the church.l am very disappointed because I have a regular size in my 3 bedroom home and it’s gas it’s great .but this one is not good . I can’t get a technician to respond

Pros
  • ‎5.47 pounds
Cons
  • No option for backup power or storage

Not like having a tankful of hot water sitting ready

It will cost you almost as much for everything to install it (to code) as it costs. By the time you buy the GFI 30 amp circuit breaker and the hoses and the installation it gets up there. After running all to code it gives you hot water at a very slow rate, luke warm at a hand washing rate, and just takes the chill off at wide open. Don't expect too much, it's ok for a shop but I wouldn't want one in my bathroom and no way could it fill a tub. Probably won't use them again.

Pros
  • I liked this electric water heater! I have been using it for a long time and it has never broken.
Cons
  • May not provide enough hot water for larger households

Not as advertised, BUT Bosch stepped up to fix it

I put this on the sink in my shop. First off, it did not work at all. I then found that the factory side of the wiring that goes into the junction block was never connected in the block. I fixed that, then. With the high/low switch on high, if I run the water as slow as I can, so the valve in this heater opens to turn on the heater, it will WARM up the water. It does not make any HOT water. I wasn't expecting this to heat the water to hot, but it barley warms it. Maybe only one leg of the 240v…

Pros
  • ‎water heater
Cons
  • No option for adjustable temperature control

not hot enouph good for me

I run the kitchen faucet on fully hot only now and the water temp is still not hot enough. I think I will use it with my parts washer to heat the kerosene instead.

Pros
  • ‎No
Cons
  • Can be dependent on the temperature and pressure of incoming water
