Clinton Hill Co-op Conquers Chronic Heat Imbalance

Most of the 1,200 apartments in the Clinton Hill Co-op have three radiators. To attack the chronic problem of imbalanced heat, the co-op board decided to install a Radiator Cozy on each radiator. The Cozy, the invention of Brooklyn-based Radiator Labs, uses insulation, a small fan and computer-regulated controls to keep too much steam out of hot apartments while sending more to cold ones. Each one has to be custom-made and installed, at a cost of $650 to $850. So the Clinton Hill board was looking at an outlay of about $3 million.
