Worcester Greenstar Boiler and DPS Heatbank

[DaveS]

I'm replacing the boiler and moving the cylinder and am very tempted to use a DPS GXV vented directly-heated heat bank with a Worcester Greenstar 29HE boiler.
This would have a zone (maybe 2) for heating and a zone for towel rails and airing cupboard, each zone having its own pump. DHW would have a recirc pump to avoid delays because of the long'ish pipe run to the taps.
Any views on any of this?

Not familiar with this particular heatbank - but be careful. If the design temperature of the heatbank is high (say, more than 70 degrees) and mostly they are high, then your expensive condensing boiler will not condense very much! To condense, at least part of the heat exchanger in the boiler must be below 56 degrees. Fundamental mismatch, possibly.
