Steam Radiators

Home / Steam Radiators

Cast iron is the proven choice for steam radiators. Ours are built to last in a range of finishes. Modern valves give localized temperature control, sound installation makes for near-silent operation.


The most flawlessly engineered cast iron radiator of our time. Crisp linear features pair with perfectly blended curves.


Lavishly detailed cast iron radiators with an intricate floral motif and scrolled tops. A traditional design with gracefully flared feet.


Grace updates the cast iron column radiator to give a striking design that sits equally well in modern interiors and period properties.


An update to the classic Princess for the 21st Century. Flawless casting, smooth flowing lines and elegant, narrow feet.

Replacing a steam radiator? 

Steam radiators are always part of either one- or two-pipe heating systems. It’s important to know which you have when thinking about replacing one.

All our cast iron radiators work with both types of system, but the configuration of a one-pipe radiator is different than that of a two-pipe radiator.

How much does it cost?

Our new steam radiators range from $800 for something small to about $2500 for a large radiator in a more expensive finish. Get in touch for a full quote

We don’t offer installation. Expect to pay from a few hundred dollars for a straight swap to a thousand or two for a more complex job.  

Usually one pipe into the radiator with an air vent on the side.

Two-pipe steam

Two pipes connected to the radiator with no vent on the side.

Shhh… just between us, steam radiators don’t have to be noisy.

    Steam shouldn't leave you feeling parched

    Our thermostatic valves add localized temperature control to stop you from sweltering.  

    Controlling steam heat

    Keep the winter air outside and save the AC for summer. Our steam valves enable thermostatic control for both one- and two-pipe radiators.

    Self-regulating sensors inside the valve automatically turn off the radiator when the room is a little too hot, and turn it back on again when the room cools, maintaining a comfortable ambient temperature. 

    What’s more, thermostatic valves save money and reduce carbon emissions. No heating system is complete without them. Read about how they work.
