<prompt> Human: This is a tip that works for someone who lives in an apartment or a house.

Aside from those two factors you can make it work with this new habit.Q: Hey Reddit, What do I do? A: Turn off your water heater at the breaker panel. Yes its that easy.Okay so it sounds extreme, but think about it...my one bedroom apartment tank is 40 gallons. Once it drops down below the thermostat setting - just like your AC - it kicks on. Its heating the water while Im away for 12-14 hours and not being used. When I get back home, I kick it on about 10 minutes before a shower and its good to go. SAVE YOUR BUCK and only turn it prior to using it.Tip works for the AC unit in the Spring and Fall seasons. My cheapest light bill has been 22.

Dont forget to wrap insulation you find lying on the side of the street around your water heater with packing tape you borrow from work while youre at it.
