You want to make sure that your pipe for your hot water or steam heating system is well insulated so that the heat travels to the farthest reaches of your house without the heater having to work too hard. Well, the best way to do this is to make sure that you properly insulate the pipes with Steam Pipe Insulation .
Although regular pipe insulation might be a bit cheaper and might be easier to find, you cannot use this type of insulation with steam pipes. Because these pipes get too hot, reaching as high a temperature as 450 degrees F in some cases. While regular pipe insulation is only approved for temperatures up to 120 or maybe 200 degrees F. So it will not work with steam pipes, but special steam pipe insulation is available that can be used for systems generating up to 500 degrees F in heat.
As far as we know, old houses might still have asbestos pipe insulation around the pipes. However, this type of insulation is no longer advisable to install since there is a health risk associated with it. If you have this type of insulation it can be covered up to lessen the risk, or you can hire asbestos abatement professionals to remove it for you. At present, fiberglass steam pipe insulation is widely used. You can purchase this from a number of different suppliers, Wanli is one of your option. Wanli makes an easy to install version that is slit down the middle to slide over pipes as well as having a peel and stick adhesive for the lap. The outer surface consists of white Kraft paper that has been bound to aluminum. You can use this type of insulation on copper or iron pipe.
On the other hand, for pipe that is located in areas with high traffic, you might want to consider adding a PVC protective covering over the insulation. This will help to keep the steam pipe insulation from being damaged, as well as helping to further limit the chances that someone will get injured from bumping into a hot pipe. It is not necessary to use this in all areas though if you would like to minimize expenses a bit.
