I recommend installing the equipment your local contractors install and recommend.

Maybe you, as the customer should make. The decision.

Navien is generally known as having the best efficiency for tankless water heaters. The best thing to do is go online and do some research on the spec or other people's reviews to give you a fuller picture.

Just curious as to why you want to switch to tankless. Is your current hot water heater not able to keep up with the demand during the day?

I think the plumbers’ opinions that you’ve received first-hand carry more weight than these phantom “most people.”

I want to free up space in my utility room, so I can make my bathroom larger. That is why I am looking to switch. Currently I am using natural gas as fuel source. Thanks for responses

Put our first tankless in homes beginning around 2003. Over the past decade my plumbing contractors have migrated from Rinnai to Navian to Norwitz. They take care of me and steer me to manufacturers with the best support. That's why I listen.
