How does a cast iron radiator work?
Because of this, many freestanding, cast-iron radiators have their pipe connections at the bottom of the radiator. The heated water enters the radiator and rises by convection, while the cooler water inside the radiator falls back to the boiler. Where there is no flow of hot water, there is no heat.
How hot does a cast iron steam radiator get?
about 229°
You’d have to get the temperature up to 400° F to see that happen (the product is good up to 500°). Typically, a steam radiator will top out at about 229°, and a hot-water radiator at about 180°.
Are cast iron radiators more efficient?
Cast iron radiators are energy efficient radiators and a good energy saving radiator choice. Studies have also shown that the conductivity of cast iron is higher than that of steel, so the heat transfer from the cast iron radiator surface into the room is much better than steel.
Can steam radiators be used for hot water?
Steam radiators and hot water radiators are very similar, so much so that in many cases they are interchangeable. While it is certainly best to use a steam radiator for steam and a hot water radiator for water, in some cases a switch between the two will require only a few simple operations.
How efficient is steam heat?
If your boiler is 2.25 times the size required for the radiators, you may be about 4.5 times oversized for the heat load. This would yield a seasonal efficiency around 52 percent, assuming a steady state efficiency around 78 percent (which is a realistic number for most modern atmospheric steam boilers).
Can a cast iron radiator be used for hot water?
Available in multiple sections and sizes, these cast iron radiators are suitable both for hot water and steam heating applications in both residential and commercial settings. Due to their simple yet robust design, cast iron radiators have a long and proven track record in the domestic steam and hot water heating industry.
How much does a cast iron hot water heater weigh?
It’s simple to install – no special parts are needed (such as diverter valves and thermostatic valve heads needed for panel style radiators). Heavy – a single cast iron radiator may weigh anywhere from 40 to 150 pounds or more and will require a physically able person (or two) to position it in place.
What’s the difference between a steam and hot water radiator?
Steam Radiator Most steam radiators are conventional, freestanding “stand-up” radiators with visible fins. A freestanding stand-up radiator is mounted on the floor and constructed of a set of vertical fins flanked by pipes. There are also wall-mounted steam radiators.
How does the water come out of the radiators?
Steam is driven through it, fills the radiators, and then condenses and runs back down that same pipe in the form of water. The water is recycled and used again in the next cycle. Two-Pipe System: In the two-pipe radiator system, one pipe delivers steam to the radiators and a second pipe separately returns condensed water to the furnace.

How much does a cast iron steam radiator cost?
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.
