I am renovating the master bath. We're at the opposite end of the house from the water heater, so I haven't washed my hands in hot water in 17+ years. I'd like to add a point-of-use electric tankless hot water heater (e.g., Bosch Tronic 7kW) that requires a dedicated 30A circuit. I have a new subpanel that I installed last year that's about 10' away (in the basement, so not line of sight).
My understanding is that the following conditions must be met (questions in red):
- I can use 10-2 wire to the subpanel and install a new 30A breaker.
- I plan to use Romex. Is this OK or do I need to use conduit or flexible steel conduit?
- It needs a manual disconnect. This can be a 30A switch. Can I put the switch under the sink near the heater?
- I am not allowed to install a 30A receptacle and wire a corresponding plug into the unit on a short cord. I must direct wire the heater. [Is this correct?] This is a bummer because I would like to be able to move the vanity from the wall, etc.
Thanks in advance for your help and advice!
