Renting here. Moved into a very old home, at least a hundred years old. The water heater is electric and just not cutting it. I want to turn up the heat, but I can’t for the life of me find the circuit breaker to cut off power before I do so. I’ve called the owner and he doesn’t know where the circuit breaker is either. I’m thinking because of the age, it’s probably a fuse box instead.

Is there a way to adjust the heat of an electric water heater if I don’t have a circuit breaker? Im tired of warm-at-best showers.
