Our home has a 50 gallon 4500w water heater. Since most of us in our household use the hot water generally around the same time of way, I would like the water heater to have a faster recovery rate. I would like to replace the 4500w elements with 5500w ones. The wire and breakers (30amp) are properly sized and the thermostats are rated up to 6000w. Based on napkin math, I think I'll achieve a 15-20% faster recovery rate. Has anyone ever done this? We plan on upgrading to an 80 gallon tank in the future but I'm looking for a simple improvement until this tank dies.
