Should I insulate the Recoup Pipe HEX within the SVP boxing?

Guidance on WWHRS insulation

We do not recommend insulating around the Recoup WWHRS, as you need heat to dissipate from the unit asap for legionella purposes. Please note due to the rotation of the water through the turbo rotator, the water clings to the heat exchanger and therefore is relatively quiet. If you need to insulate the SVP for noise purposes, then a panel divide can be built between the pipe and SVP, which may increase the box size - see related article.
