HELP- Navien Combi tankless water heater

I had a plumber install a Navien Combi-Boiler with a tankless water heater a few months ago and I do not have consistent timing on obtaining initial hot water.

Sometimes I will turn on the kitchen faucet or upstairs shower and it will take over 2-3 minutes before i get hot water. The Plumber tells me that this is "normal" and I should expect a delay.

I already paid in several thousand dollars and I do not want to give him any more money. Any advice?

Call the manufacturer and speak with a supervisor about your dissatisfaction. Is the water heater still under warranty?

If it's "on demand" water heater, 2-3 minutes is not instant.
