What Are Cast Iron Radiators?

Many old homes were heated with cast iron radiators before the invention of forced air heating systems that many of us know today.  Cast iron radiators relied upon the heated water from a boiler that would circulate through the "coils" of the radiator, heating the air around them and thus the room they were in.

Cast iron was a popular choice for these radiators that often were bland in design.  However, the designs became more popular and stylish as more people were using them and demanded something with more visual appeal to them.

Those old radiators that many people remember as clanging and banging around when the water would begin to circulate are gaining in popularity again as a way to heat your home for less.  Along with radiant floor heating systems, heated water radiators are an environmentally and financially viable option.  The old cast iron radiators are even capable of working with modern boilers and radiators to add a stylish look to your home.

The Benefits of Using Cast Iron Radiators for Home Heating

One of the benefits of using a cast iron radiator for heating your home is that they don't produce moving air currents.  Some people with severe allergies require a limited amount of airflow in their home in order to prevent stirring up allergens and dust.  Along with radiant floor heating systems, cast iron radiators and more modern radiators work well to provide heat to your home.

Another benefit of using cast iron radiators in your home is that they work with modern heating systems.  If you have radiant floor heating or a boiler, you can tap into that heated water to use the radiator as a means to provide additional heat to your home.

Most radiators were situated in areas that had the chance of allowing the coldest air into the room.  That is why most radiators sat underneath windows or close to them.  The more modern radiant heaters are much smaller and more compact, some even fitting into the walls so that they appear to be molding.

If you are a fan of old homes or restoring old things, the benefit of finding, restoring and using cast iron radiators is another item of interest.  Many old radiators were destroyed or turned in for scrap.  Finding and restoring old cast iron radiators is a growing business.  If you are able to find old radiators or are restoring an old home with them, cherish them and have them restored or fixed instead of pitching them out with the garbage.

I have always been interested in cast iron heaters. My home is totally electric, but being able to use radiant heat is very compelling. My area has no gas lines to the home, only electric. Is there a way to heat the water and pump it to the radiator without relying on electric or a steam supply? You have written an excellent hub! Thanx

Steve, I don't think so, however your boiler company can verify as they would know the water types in your area and any other code requirements as well.

I have Cast Iron Radiators and I need to replace my boiler. Do I need a cast Iron Boiler to keep the metals the same?

Great Hub. I love the look of radiators, especially in older homes.

Hi Ellen,

I would remove the wooden cover and also don't let any combustibles touch the radiators when in use. Although the radiators aren't like an open flame, they do build up enough heat that over time in contact with certain materials, they can catch fire due to the length of heating them.

I have cast iron radiators in my condo... the largest one came with a wooden cover, is it safe to leave that cover over the radiator when it's on full blast??

Also, the one in my bedroom doesn't have a cover. My curtains touch the edges of the radiator- is that a fire hazard??

THANKS SO MUCH!

Hi Josh,

There are several ways to turn one on, it just depends on how your heating system is configured. Most cast iron radiators have a valve that will shut off the water flow to them, you want to make sure that it is open. You will also need to verify that your boiler or heater is running and that any other valves that need to be open are opened.

The best bet is to call a licensed contractor to your location for service and to verify that things are the way they should be if you aren't familiar with your system.
