Over the past 2 years I have seen many posts showing piping for the boiler. I have yet to see any insulation on there pipes. I have about 20 feet of exposed copper pipping and have insulated all of it. I still have about 15 feet of iron pipe to insulate yet. Have not been able to find insulation for the 1 1/2 Iron pipe yet. I am sure there must be some heat loss with these pipes reaching temperature in the 180 degree F. Do many of you insulate your pipes or am I wasting my time and money insulating the boiler pipes.
