- Critics were mentioned primarily few criteria to choose the device, for instance: the grey colored design, for being tiny it’s easy to transport and takes little space to fit.
- Next, the digital thermal reading system helps to give proper measurement, control over the device.
- Through that, one can fix temperature by the assist of thermostatic curbing limit technology, ranging from 90 to 135 degree (F) almost.
- Coupling with that thermostatic controlling range, the flow rate can supply 3.7 GPM water in usual season and 1.9 GPM in the coldest season.
- For generating the supply, it takes less amount of energy; hence, the electric bill has also ripened into 50% down.
- Also, the corrosion and rot resistance has incremented the overall efficiency into 95% so that the durability confirms.
- This long-lasting device needs three individual DP circuit breaker, 240 volts, 75 amps for the entire house, 8 AWG wire to survive as a guardian of the galaxy.
Expert opinion: Since the device has chosen from critic forum, most of the user from that forum knocked for not having on demand water supply, to fix the issues our review team has detected some common reason which will be discussed in expert solution option.
The problem arises for the blockage of the air intake, awful igniter, for a defiled burner or less gas supply. Therefore it’s good to call e plumber to solve the issue rather than do it by yourself.
Finally, our expert team has come to an end with 11 kW water heater which is used downstairs of our office. Since we have been accustomed to it for five years, deserves to be listed in our review. For pulling this in our list, has to consider some basic features and dibs. Permit us to talk something about our downstairs guardian:

- With that control board, our users can set 86 to 126 degree (F) temperature. Between that temperature ranges, the heater can produce 0.53 GPM water at least.
- Moreover, this NFS approved device has the ultimate electric and overall efficiency, reflected at the monthly electric bill. Even it is far lower than our previous electric tank.
- For serving those supports, this ETL listed machine needs only one 50A type circuit Breakers, 240 volts, and 46 amps electric supply to the house minimum.
- Also, it can serve you for five years with an unlimited warranty; seriously, we are benefited with that even.
Expert opinion: On that five years journey, we did not face any significant issues, but from another user, we have got a question such as: shutting down during shower. For assisting regarding the problem, the team requests you to check the following criteria:
From our in-depth research, we have found that the problem usually occurs, when the flow rate of the heater crosses its limit. So check the warranty and then call a plumber to fix the problem. If there is a warranty, the company will fix that.
