- Make sure you have ~50psi water pressure. For city water use a pressure regulator to verify your pressure and to make sure it is not too high (can damage plumbing) or too low (can prevent tankless heater from working properly).

- Do not use the cold water with the hot. Set your desired temperature and use the hot water only.

- Do not run water at any other faucet when using the hot water.

- Be sure to pull the strainers / flow restrictor on all the faucets and shower head and clean them from construction debris and other contaminants.

- Pull the strainer in the fresh water pump and make sure it is clean.

- Make sure your house water filter is not clogged and restricting flow.

- Check the water valve on the back of the water heater to make sure it is about half way open.

If you have adequate pressure and flow, it should work just fine. I can take a 30 minute shower and never run out of hot water.
