    • 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

    • 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.

    • Typical junk that doesn't last
Model: V7B-140B
It was nice while it worked. Less than 4 months and it stopped heating and screen does not turn on. Water is mildly warm but not even close to actually warm. So seems like flow sensor is working and at least some of the heating element is good. But yeah, junk is junk. Looking for another heater now

    • 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.
