    • Great value for the cost
Model: V7B-140B
I bought this as was one that was in the lower end of my budget. Installed it about 6 months ago and still working great. Provides Hot water pretty fast. It is a space saver. Installation was easy and I think it is a great value for the money. I have a total of two, the other one is pricier (I'll call it brand X). If I needed to purchase a third one, I will definitely buy this same one instead of brand X. ... show more

    • So far so good
Model: V7B-240B
Review Image by Amazon Customer
So far, this is working great for us. The water comes out hot, and although the temperature drops during the shower, it's not that bad. I'm waiting for my first electricity bill to see how expensive it's going to be. I'm electrician so the installation was done super easy.

    • We love it
Model: V7B-140B
This thing is awesome for the money. My standard hot water heater went out so I figured I give this a try and it's been great. It did leak out of the inlet so I had to grind down part of the inlet screw/screen so that it was more recessed and could seal better. Just make sure your wiring can handle it. It gets extremely hot we love it! ... show more

    • Spend the extra money for the model V7B-240B. It will heat up more water.
Model: V7B-140B
I bought the Model: V7B-140B It works great but if you use more than one faucet at a time, the water does not get as hot. I just turn the water slower and it heats up better. If I had to do it again, I would buy the Model: V7B-240B it is almost 100.00 more but it heats up more water at a time.

    • Hot water
Model: V7B-180B
I like the idea of it taking up less space, but you will need to adjust temp, it will get very hot and then get very cold. I’ve adjusted so we only need a little cold water to manage the temp in shower.
