I have looked at the glow worm and it is considerably cheaper and out
of what is available seems to be a reasonable product. If I can't get
suitable answers from DPS and Eco Hometec regarding the Man and the
Pandora then I may yet go down this route.

Also, consider the Worcester Bosch Greenstar with additional diverter valve
(assuming they still make it in the new range). This allows separate
temperature settings for DHW and CH. Technically, the DHW is (or was in the
previous version) limited to 75C and the CH is limited to 85C, but we
couldn't see a reason why you couldn't swap the circuits, although a relay
might be required to get DHW priority instead of CH priority.

This way, the boiler can produce 82-85C for the Pandora and drop to 60C for
the CH, which is safer and more efficient.

I have the WB and the Pandora, but didn't specify the diverter, which I
probably regret now, as I have to run the rads too hot.
