True, but my goal is to never use the electric water heater again . Although a 90 f. shower is doable for me but i prefer 100 f. I do like the attic idea though and i can take my showers late in the afternoon if need be while the attic is still warm in the winter. But my project will guarantee hot enough water in the winter months.
