Replacing radiators needn't be a chore

The 150 year-old one you already have can easily be replaced with a brand new Castrads radiator.

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.  

One-pipe steam

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 (coming very soon) 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.   

One-pipe TRV

Creates an air barrier to prevent steam from entering the radiator

Two-pipe TRV

Closes off the inlet to prevent steam entering the radiator

What type of heating do you have?

Steam radiator valves

Take control of your steam heating with thermostatic valves for one- and two-pipe radiators. 

Our valves are in development right now and due for general release spring/summer 2019. Installation is simple and the valves are cost effective. They’re easy to add to existing radiators or to install with new ones. 

Thermostatic steam valves are the perfect antidote to stifling apartments, overheated brownstones and searing townhouses.
