On demand Vs tank water heaters
Is anyone using on demand systems to heat just hot water instead of the traditional tank? I saw a post from 7 years ago where people weren't hot on the on demand system reliability, but I'm sure they have gotten at least a little better. I'm inclined to swap natural gas HW tanks for electric when they die to make it easier/quicker on replacement, but curious if anyone has been using tankless as they claim to have a longer life.
I'm assuming the benefits are mostly eaten away by the initial higher cost, especially if the tenants are paying for hot water and therefore no savings there.
Specifically looking relating to a triplex and a quad with NG atmospheric tanks in place (A few electric tanks are in the mix as well).

I only have on demand at my primary residence. The gas connection like all appliances has a flex connection from the valve on the steel pipe to the unit. That set up shouldn't be any slower to change than an electric. All my rentals still are tanked based on the cost. Not sure I trust the complexity of the on demand system to last substantially longer than the tanked version.
