Any advantage to second lagging jacket on cylinder

    As the thread title asks, any advantage to fitting a second lagging jacket to hot water cylinder with the second jacket covering the jointings of the first one? How much more efficient would one of those insulated cylinders be in comparison?

    I used to have an old cylinder with a duvet around it, I eventually bought a lagging jacket to discover the duvet had done a better job! I now have one of the insulated tanks after old one leaked and again I think the duvet was the best of the lot for keeping the water hot.

    So if you have an old duvet wrap that around the existing lagging jacket and squish in around the back.

    A proper insulated cylinder is massively better than a insulated jacket or even two jackets. I'd go as far as saying the insulated jackets are a waste of time mainly because its impossible to get them to fit properly so I can see how a duvet might be better but not better than an insulated cylinder.

    Wake me up when it's all over.
