I installed a Pandora a few weeks ago after reading Christian McArdle's
review. I considered it along side an unvented cylinder such as a
Megaflo, but decided in favour of an unpressurised cylinder because the
layout of my house does not lend itself to easily accommodating the
pressure relief pipework. A bonus was that I could get a tall, thin
cylinder which would still leave me some useful space in the airing
cupboard. Now I have installed it, I'm not even sure the Megaflo would
have fit in the cupboard. The narrow cylinder also gives me scope to
relocate it to the loft if I decide to do so in the future.

So far the performance has been as expected.

If it needs topping up you'll soon know, because you won't be getting
any more hot water. The fill level is just above the level of the
take-off point for the pumped side of the heat exchanger.

I have not actually measured the pressure of the DHW to compare with the
cold main but they are similar - if I turn on the hot and cold taps in t
he cloakroom they produce similar levels of embarrassing water splashes
on light coloured trousers. The heat exchanger certainly seems to do its
job.

hope this helps

Neil,
Can you point me to the review you mention please. Also, how much does
one of these things cost?
