I work for a water supply company ad all our pressurised tanks/vessels are
inspected once a year, this is due to H&S rules in the water industry but I
would say your friend will need a certificate of safety

I've been reading up about heatbanks and pressurised DHW systems in
the archives and am sure I came across a comment that PDHW tanks have
to be inspected annually for insurance purposes.

Can someone confirm this please? I've been visiting a friend who has
just bought a backpacker's hostel and he showed me this large HW tank
and mentioned there was no header tank. Having never seen a
pressurised tank before and read about the inspection thing, I asked
him about this and he didn't know.

To further confuse the matter, I've been looking at the Megaflo tank
specifications on the Heatrae Sadia website and it says that no annual
inspection is required as there is no sacrificial anode (or was it
cathode!).

I've raised a little bit of concern on this guy's part and it would be
better if I could get a definite Yes or No to pass on to him.
