Yes, it is expected to meet 2 points of use throughout the whole house.

What are my considerations when installing it?

Use the supplied drilling sample to determine the location of the mounting holes. When drilling holes in the wall, be sure to avoid buried electrical wires, water pipes, or gas pipes in the wall.

What amp breakers are required for 18kW and 27kW Electric tankless water heater?

The units of 18kW requires a 2x 40 AMP breaker and 2 x 8 AWG gauge wire. And about 27kW requires a 3x 40 AMP breaker and 3 x 8 AWG gauge wire.

If you have a lot of sediment in your water, it is recommended that the unit be flushed and descaled at least once a year at a minimum, removing the heating elements and cleaning them prior to flushing.

We usually suggest you can check whether the connector is not installed in place or not, and then tighten the connector. And another problem is you need to replace the seal.
