Pressure vessel in loft - does it need insulating?

    With a pressurised central heating system, all pipes and taks are insulated in the loft apart from a small pressure vessel which is located on the loft floor above the insulation.

    It was suggested this should be insulated as it consists of half water / half air.

    I haven't had a problem that I know of so far. Does this tank need insulating?

    Thanks for any info

    To be honest I have never seen them insulated in all my years.

    I have never seen them insulated either. I wonder is it because occasionally you see condensate on the outside of them?

    i have stainless steel cylinder in the attic . the flexible pipe to the pressure vessel had no insulation frost traveled up to the caleffi inlet valve which was insulated and froze it . had to use heat gun to get it going again that was two years ago, so i insulated the flexible pipe and wrapped earthwool around the pressure vessel no problems last year and it got down to -15 here in kilkenny
