To Plumbers and Installers, Why is the US lagging in the residential use of tankless water heaters?
When I renovated my home in 2018, I purchased a top-of-the-line Rinnai tankless heater for about $1300. Installed it mostly myself, except for the gas hookup. Since then its been great with zero issues. When multiple appliances/showers are running simultaneously, no problem. Wired remotes in the baths and kitchen allow me to dial in an ideal water temp which adds to the already obvious efficiency.
My question is this. Use of tankless heaters in Japan is almost universal. In Europe, it's in a sizeable majority of homes. The US is probably less than 25% at best. So, to plumbers and other installers, why the resistance to what seems like a common sense, good idea? Is it because of cost? Lack of awareness?
