Buderus GB142 Multiple boiler installs

Putting in 3 142/35s to satisfy loads as follows...
212kBtu heating (radiant)
190kBtu snowmelt - Low Priority
150kBtu indoor pool heat
119 gallon IDHW - High Priority
80 gallon IDHW - High Priority
Plan to use tekmar 264 boiler sequencer inputing to an outdoor reset control to control two mix temps (wood and slab)
Going to preheat incoming IDHW feeds with the boiler return via tube exchangers to depress the return temperature. Does anyone have a calculator or table for figuring the the tube exchanger sizing?
Looking for any experienced input as to pitfalls of sequencing these. They were chosen over the MZ and the W-M.
