Restoring The Smooth Looks Of Your Radiator
The heating radiators that are presently being used in many homes can be either be refurbished or a replica of those old time cast iron radiators. There is not much difference between those two in terms of functionality. But when you speak of sentimental value especially to those who have the passion for antique items, the refurbished ones may have a great edge. The radiator replicas being sold these days can be considered brand new. That is, a fresh new paint coated over the bare cast iron gives it an evenly textured surface making the radiator look neat. On the other hand, the refurbished ones are made to look like new by, more often than not, by just covering them with a new layer of finish or paint. As such, those restored radiators tend to exhibit an unevenly textured finish making them less nifty-looking than the replicas.
If you are the sentimental type who prefers to use cast iron metal radiators from the olden times and would want to restore them to their brand new looks they once had, then the best thing to do is to strip the paint or finish down to the bare cast metal before applying a fresh new coat of paint. There are three most common ways to accomplish this – using chemicals to get rid of those layers of paints and stains, manually scraping or chipping the paint, and sandblasting.
Manual scraping of the paint is a tedious process because it involves thorough chipping and scraping. Crevices and narrow areas on the radiator assembly can take some time to chip away the paint from those areas. Tools that will be needed for this undertaking are wire brushes, hammers and sandpapers.
Sandblasting is an old but effective method to chip away all those paints and stains that might have built up over time. In addition,
patches of rusts and tarnish resulting from the chemical reaction between the cast iron and some elements present in the air surrounding it can also be removed effectively and quickly by employing the sandblasting method. However, the tools needed to accomplish this might not be easily available in an average household. Purchasing a sandblasting equipment set might not be a practical approach. You do not need it at the house more often to justify the costs of acquiring it. What most radiator owners would do would be to take the radiator from the heating system and send it to a sandblasting contractor. Keep in mind that this will have to incur some added costs such and a bit more effort considering that you have to remove the radiator unit from the whole heating system.
Employing the use of liquid solutions or chemicals can be the quickest way to remove all those layers of paint. All one has to do is to dip the whole radiator into the solution and wait for a few hours until the old layers of paint fall off thereby exposing the bare cast iron metal in its clean and untarnished state. However, this could get a bit disorderly considering that you would have to deal with a mixture of chemicals and solutions. But despite the painstaking labor one has to undergo, nice results can be had when those rickety looking radiators are now transformed into sleek and classic looking antique cast iron radiators.

Hot Water Type Radiator Maintenance Tips
Like every other piece of equipment or thing that you happen own, a cast iron radiator may need some maintaining to do in order to put it in great shape all the time. A poorly maintained radiator will tend to deteriorate in functionality. Hence, the need to accord periodic maintenance schedules for them. It does not come by more often considering the fact that they are just being used during the cold months. Technically, the cast iron metal, by its nature, is a very durable material. This gives them a much longer lifespan than radiators made up of other material types. There are two main areas in maintaining your radiator thereby keeping it in tip top shape – bleeding and lea. We will discuss saliently each main step for a better understanding of the whole scenario when it comes to proper maintenance of the radiator units which you may have in your respective homes.
Bleeding the radiator simply means that you bleed out the air that might have accumulated inside the coils. Cast iron radiators are designed to be air tight and water tight. However though, air can seep through the system in a variety of ways. When that happens, the air in the system hampers the flow of the heated water through the coils and might exert a great deal of stress to the circulator pump which might result to its damage. As such, the heating capability of the radiator unit will deteriorate. One way to determine if the plenty of air is already in the system is when the radiator is already running cooler or generates insufficient heat. If you observe such, then it the air in the system might be the likely culprit.
Bleeding the air from the system is a very simple step actually. All radiators have vents which are purposely used for bleeding air. They are most likely located near the top of the assembly in most radiators. All you have to do is to turn the vent using some tool such as a screwdriver or a wrench to let the air bleed out. However, one must take due note that the vent must only be gradually opened so as prevent a lot of water from squirting out. Once a solid flow of water from the water starts sputtering out, it means that the air is completely drained. As you can see, bleeding the radiator is just a very simple maintenance undertaking actually. It does not take much effort to do it and the benefits you get out of it can lead to a longer uninterrupted service of your hot water radiator.
