I read somewhere that there is a difference in electric water heater elements. There are "standard" ones and then there are some that are"low watt density". From what I read the "low watt density" are supposed to be more energy efficient? Is this true? Also, do you know anything about an element called a "sandhog" or something like that. It is a very curvy element that is supposed to last for years?
Also, do you think that you save energy by having the thermostat on 120 versus 140? I feel like at 120 we use more hot water showering than we would at 140 plus the dishwasher runs a long time at 120 heating the water.
Appreciate any thoughts/advice you have on this.
