Abstract
An appropriate volume segmentation method for a multi-nodal energy model of a vertically oriented stratified electric water heater tank is determined through the use of energy balance during steady-state cycles under different thermal insulation schemes. A multi-nodal approach is chosen due to the transient limitations of single-node or bi-nodal methods during draw events. This paper only focusses on the steady-state condition to prepare for a multi-nodal model for draw events. This energy balance methodology will be extended to the tank in dynamic state.
