Blowing Off Steam: The Case for Variable Refrigerant Flow (VRF) Heat Pumps To Replace Steam, New York’s Biggest Energy and Water Glutton

Steam heating systems are widely used in New York State, in all kinds of buildings: universities, large high-rises, schools, and even homes. We know that converting steam to hot water systems routinely saves 50% of the heating energy use, as well as saving water. But it is not known how much steam heat in fact exists in the state – it is just not something that is inventoried in any of the various building information databases. So we set out to estimate how much steam is used in different kinds of buildings, and were surprised with the results. We also evaluated the savings to convert from steam to a new type of heating technology, variable-refrigerant flow heat pumps. Join us to learn how much steam we are blowing off, and how much we could save by converting steam to VRF heat pumps, in a fast-moving and information-filled session.
