hi
my shelf chiller is struggeling to keep up in this unseasional hot spell any ideas i can do to lower the load on it
i have the python supplying a coil of 10mm copper tubing wrapped around the cask the cask/cooling coils are wrapped in 7m of foilised bubblewrap to insulate it (that is normally enough)

It doesn't sound like you can do any more to insulate the kegs, and I guess the lines supplying the coils are insulated too.

So you might look at the siting of the unit? You can't insulate it! It would quickly overheat, but you can make sure it is sited somewhere with good ventilation so the hot air (lots) it generates doesn't hang about it. That's all I can think of. My own shelf-chillers aren't properly commissioned yet so perhaps I'm yet to learn more in-depth tips (and learn fast; the newly brewed batch is sitting in its secondary at 19-20C).

"Unseasonal hot spell". It's Summer! Give Blighty some credit.

the pipes are not insulated as im running 1/2" inside diameter reinforced food grade PVC pipe i could run the python pipes in 3/8" line insulated
eventually i will improve the insulation around the cask into a proper jacket (just got to find somebody that can help me do it (ideas welcome ie to sew or to glue?)
really struggeling in this hot weather the ice bank is struggeling to get below 4 degrees

If you know anyone in the printing business, magazines and the like. Ask if they use off-set printing blankets. Buy a used one and see if it will fit over the cask. They make great insulating material. Thick, multi ply rubber coated materials.
