Anything new in waterheaters?

[Marc Bergmueller]

I've been looking for a replacement for my water heater. A few owners ago the saildrive was removed from my boat and replaced with an outboard. Right now I have a solar shower bag but have thought of adding an on demand 120v water heater for dockside use. Are there any other ideas out there for anytime use?

Not new but I like this Bosch GL4. Our local fuel dock located way out on salt water uses it for the public restroom. This Amazon price is good but look around. The problem with on demand water heaters is the 240v needed to run them, this on is a more normal 120v.
