Cast Iron Radiators FAQs


No! Cast iron radiators providing steam or hot water heat are the most efficient, quietest and most comfortable of all heating systems. Converting to a more “modern” method is costly, results in less comfort, and increases heating costs.

The worst choice is baseboard heating because convection is up to 30% less effective than radiator heating, requiring higher water temperatures plus more BTUs and fuel to deliver the same amount of heat. Baseboard systems often require replacement because of overloading. (If you have cast iron radiators, count your blessings!)
