Multifamily Central Heat Pump Water Heating Retrofits: Learning the Hard Way

We will share our experience with the design, permitting, installation, commissioning, and operation of 14 large-capacity central heat pump domestic hot water heating plants in low-income multifamily buildings (20 - 120 units) in disadvantaged communities in NYC and California. Manufacturers installed are Lync, Mitsubishi, Aermec, and Waterdrop.

What works? What does't? This talk will share the many lessons we learned the hard way, in order to help accelerate the adoption of all-electric water heating systems in New York.
