How does this help cost?

Read post 15 and the torch scenario small torch runs forever never gets to temp burning using lots of energy big torch uses lots of energy just for a couple of minutes but totally a lot less. His heater as soon as the pump comes on within minutes water temp drops from 110° to 80 - 85° never gets to set point of 110°.
Building needs better insulation and roof/ ceiling but with 70 gallons of water in system theirs a lot mass.

That doesn't change the energy consumption no heat is being wasted all the energy is being turned into heat.

thats right but with one element it never turns off and only satisfies when the outside load warms up or system stat is turned down. Two elements with cycle.
