The Last Frontier: Solutions for Fossil-Fuel-Free Domestic Hot Water

Natural gas moratoriums, consumer demand for fossil-fuel-free homes, Passive House standards: these are among the many reasons why people are increasingly opting for domestic hot water systems powered by renewables. As improved energy codes drive down heating loads, soon the largest load in the home won’t be heating or cooling; it will be the domestic hot water system. This session will explore the options for fossil-fuel-free domestic hot water, achievable in nearly all projects, single family to high-rise, in both new construction and retrofits.
