Isn't it true that only one of the heaters would function? I say this based on the fact that they cannot be set at precisely the same setting.
One would turn on first, then with its heating effect the other wouldn't even get to turn on. I'm assuming there is adequate current to spread the heat evenly around the tank and overcome the thermal inertia of the water.
If this is true then the other heater would only come on if the first failed, which is a good thing anyway....or if I changed in cold water.
I guess it would also mean that I should buy two heaters that are each capable of heating the tank on their own so that it doesn't take too long to recover and they don't get too stressed.
Is this the way it works or am I just talking through my hat?
