Vitodens 200 combi model 25-91

I'd like input on the vitodens 25,000 to 91,000 BTUH Boiler in the combi model. How reliable/how is the good is the hot water output? I know what the stats say - something like 2.1 GPM @ 128 degrees with I believe a 60-70 degree temp differential if I'm not mistaken.If I used the existing electric bradford white lowboy as a pre-heat tank to say 80-100 degrees then this technically should really help output as well.

I've asked about the vitodens 100 and loch. knight wb050 so I'm trying to garner info on this one, the most expensive of the options.

With 5 loops of radiant at 250-300 feet each roughly, I figure the Vitodens BUS Pump would probably have enough juice to do the radiant too (thoughts?).

Thanks,

Scott
