unvented and secondary return circulation

[migoplumber]

lots of the larger cylinders i work with, have anti "stratisfication" pumps on them.
basically a pipe from top of cylinder, joined to the bottom of the cylinder with a bronze pump.
helps keep the cylinder tempereature equal from top to bottom, and wont confuse your stat to thinking everything is ok when its sat on top of cylinder reading 65 degrees, whilst at the bottom you have a lovely 40.

i imagine the same principle works for smaller cylinders.

I did the legionaire course, got shouted at by all these funny french blokes in poofy hats chasing me across the desert. By the way, frogs legs taste like chicken but ya can keep the fuc#ing snails. 😀

But seriously, is it worth doing the legionella course, its about £90 if im not mistaken but the basics are covered in the water regs! All for health and safety but £90!!!

Will surely read the above recommended leaflet - peace out.

The CIPHE design guide has a page on Legionella, and it cost only £40 to non members and I think £25 for members, half the price of going on a course

But if you like and when I can find it, I could post the actual French legislation on hot water cylinder and the risk of Legionella, and the methods of prevention
