Thermal storage water heater (Gledhill PulsaCoil)

As a related follow on to my viewtopic.php?p=493473#p493473 ("Considering replacing my traditional vented 180ish litre hot water immersion heater with a direct unvented one instead"), I wonder if anyone has any experience with a thermal storage system for providing mains pressure hot water from off-peak electricity, such as the Gledhill PulsaCoil?

https://www.gledhill.net/products/thermal-storage/pulsacoil-stainless/

Seems to have some big advantages over the unvented systems, in particular that as the thermal store is vented there's no need for a discharge pipe, and there's no annual maintenance needed.... :D

I may be wrong but I think Mike the boilerman, member of this forum is worth contacting. Mike4?

He runs a forum on Gledhill products.

Thanks. Lots to read. :D

Is the number of posts in you Gledhill Repairs discussion forum indicative of the reliability (or lack thereof!) of those? I note you don't have an advanceappliances-repairs.co.uk, and is that also indicative of their (much better) reliability?

Also, I note the comments in https://www.pulsacoil-repairs.co.uk/replacing-a-pulsacoil.html although those seem to be a little out of date in that, IIUC, the Pulsacoil ECO Stainless has been replaced by what you call the Pulsacoil Stainless Mk2, which they call just the Pulsacoil Stainless and is, if I've got this right, the one I linked to in my OP.

So, considering that, would your comments be much the same now? (BTW, Advance now also do a 210Litre one.)

I'll go through all that, but now I'm also wondering if it might just be easier to add a pump on the hot water output of my current vented immersion heater (after the vent pipe of course!), and change the bathroom cold water supply to the mains (relatively easy to do). What's your view on adding a pump to a gravity system for getting decent pressure?
