The best buying guide for cast iron radiators

The first cast iron radiators appeared in 1841, and during the next 50 years, some of the designs and production techniques still in use today evolved from them. Each radiator has discrete cast-in-a-foundry components that get machined and joined with connecting nipples and gaskets. Cast iron has the mass and storage capacity to hold and radiate heat into the room even after your boiler has shut off, which is a significant advantage.

Finish & Colour:

Color can have a significant impact in addition to the cast iron radiators’ shape, designs, and elaborate details. For radiators from cast iron radiator ranges, which have more prominent features, a hand-burnished finish or “wash” can apply to highlight the design or even give the radiator an aged appearance. Cast Iron Radiators can even be hand polished to bare metal; yet, this shiny surface needs minimal upkeep to maintain its spectacular appearance and prevent tarnish.
