Radiator Labs's low-cost, easy-to-install and patent-protected retrofit converts old cast-iron radiators into precision heating machines. Our low-cost radiator retrofit allows convective heat transfer turned on and off at each radiator location without contact with plumbing. The product is sold both directly to consumers as well as through channels to building owners. Residents benefit from greatly improved comfort while building owners/managers gain building-wide heat distribution control and significant system-wide energy efficiency gains through reduced global overheating.
