Radiator Labs is solving a 100-year-old problem: the lack of comfort or efficiency in radiator heating systems. The Radiator Labs Cozy is a smart hardware cover for radiators. Combined with our Building Optimization Services management system, we yield energy savings that are 3x better than smart thermostats like Nest. Radiator Labs delivers a value proposition for everyone involved: building owners increase their net operating incomes by 10% on average through fuel and maintenance cost savings, and their tenants benefit by being able to control their temperatures for the first time in the history of this building type.
