In Hot Water: Key Design Details to Make Efficient e-DHW Attainable for All
As we move rapidly towards an electrified future, we must re-evaluate design guidelines that have served us through the last century of abundant fossil fuels. Domestic hot water (DHW) production is a prime example of this evolution. Following up on past NESEA presentations on heat pump DHW design, this session compares long term data from two DHW systems in Central New York. While both systems demonstrated remarkable effectiveness, our analysis uncovers how subtle design variations yielded substantial efficiency differences (up to 50%). Engineers, owners, and program managers will all benefit from evidence-based design guidelines for the sustainable infrastructure of tomorrow.
