Sounds like he should no such thing. He needs an "integrated" heat
bank
and
run the rads off the heat bank. Boiler cycling is eliminated. Run
the
heat
bank between 72 - 75C and set a primary blending valve to 54C.

You can (and should) zone the radiator circuits even when they're run
off
the heatbank, you know!

I know and they should, be run off the heat bank, directly if possible,
as
the heat bank is a neutral point, "not" off the boiler. All should be
off
the heat bank, with the boiler only heating the heat bank.


Only if a conventional boiler or other heating sources are used, not a
modulating condensing boiler.

You don't know much about this sort of stuff.
