User questions & answers
| Question: | Do you need electric to the tank |

My unit runs in the on position so when I open the hot water valve at the faucet it will allow hot water to flow. |

User questions & answers
| Question: | can this 6.6 gpm tankless water heater be ok for a 2 bathrooms and the kitchen |
| Answer: | Probably not, certainly not if both showers are running and the kitchen sink. Use the Navien 240-A instead. This is a 40 gallon WH replacement only. |
| Question: | Do you just run the 2" vent pipe trough the existing 4" liner? Seems like a pain |
| Answer: | I ran the flex myself through our existing B-vent. I had the benefit of a perfectly straight run up to the roof and less than 5'. Very easy and probably took me about 20 minutes to install the vent line. Measuring/cutting the flex to length took the most time. |
| Question: | Anyone using this in a place that has colder ground water like washington state |
| Answer: | Yes. When I lived in Bellingham, WA. I replaced my tank heater with this system. Had no issues with it providing hot constant water at the factory settings. |
| Question: | Is it noisy, loud |
| Answer: | I don't find this noisy at all. There is a small noise that I can hear from the closet it is in if I am listening for it, but can't hear it above the HVAC or water if either are running. It is mounted in my house on a wall shared with another room and noticed a small vibration that I can hear from the other room when it is running, but nothing more annoying than the other normal noises in my house. |
