    More Insulation...

    Having the first dry day in about 3 weeks i finally managed to get my pump feed and return pipes insulated,
    with rubaflex nitrile 25mm lagging (same as armaflex but cheaper)
    I lagged the pipes in the filter house a week or so ago,

    but was putting off digging up the pipes i buried when i built the pond,
    as it was going to be a crappy job at this time of year...

    all done for now anyway...
    until i build a new bigger pond next year...

    Nice Job, Is that insulation waterproof, used loads of Armaflex, but mainly indoors and been wondering how it would fare out in all weathers?

    I've used armaflex outdoors. Can't find much detail on it but this video says its preferable to the standard foam insulation:

    Nitrile is fairly uv resistant and closed cell.
    I've used, and seen it used outside on site for years...

    Armaflex do a hard shell nitrile lagging that's better, but it costs a fortune.

    I got 10 mtrs of 54mm x 25mm
    And 14 mtrs of 42mm x 19mm
    Rubaflex for about 100 next day delivered.

    Thanks

    Anything that helps to save the electric heating over the winter
    The pond had 4 layers of foil bubble wrap insulation under the liner to help a little.
    A 2" pipe uninsulated can lose around 50watts per hour per meter in heat. So can soon add up with over 20 mtrs of external pipe.

    the last pic was before back filling the trench.
    It's all buried under 6" of soil with bark chips on top

    plus i used to work in site maintenance, and a while ago took the advise of the pest control contractor. 'jerry the ratman'
    there are no 'live' rodents in my garden... well not for long if any are any...
