It continues to absorb energy from the burner or heating element until it is hot enough to use.
Having a large water surface exposed will result in rapid drop in tank temperature. The installation of efficient insulation significantly reduces heat loss. Their goal was to pretty much eliminate their propane bill, which is exactly what we did. Uses very little propane because of the box. But this can be difficult to operate unless the system is mounted on the ground.
This approach is common in climates where freezing temperatures do not occur often, but can be less reliable than an automatic system as it relies on an operator. It warms the water up for the conventional home tank. But that would be an additional costly expense. Daily, home owners begin to take the plunge into renewable and sustainable sources of energy.
