Radiator Labs had received contracts from the managers of seven buildings agreeing to serve as pilot sites for the commercial product demonstration over the 2014-2015 winter heating seasons. The building owners agreed to cover 40% of the cost of the pilot, and NYSERDA committed to cover the remaining 60%. However, the agreement created a cash flow issue for Radiator Labs. It needed to pay upfront for manufacturing and installation but would not receive payment from the participants until after installation and finally measurement of the energy saving results.
