Gas Hot Water Heater

We have two gas hot water heaters in our house. One is for the bathrooms that we rarely use unless we have guests. I would love to be able to remotely adjust the temp on these guys, especially the one that is rarely used since it’s difficult to get to.

I’ve searched around but couldn’t find anything. Any suggestions?

rather than fiddling with your current hot water heater you might want to look into a point of use hot water heater. (AKA tankless)

even if you could remotely adjust the setpoint you would still have the pilot light running 24/7/365.

I’m not really sure of the economics but something used infrequently sounds like a great application of one of those.
