Choosing a boiler again... but can anyone suggest any non-modulating

a
choice of more than 1 would be good.

This would be for a Thermal Store system, for which flame modulation
is
(in
theory) an unneccessary waste. On the other hand, I'm thinking I might

better off just 'going with the flow' and getting a standard
(modulating)
boiler regardless of the redundant fucntion.

Egremont.

PS - there is a background that's been gone into in another thread
(which
I'm still looking into...)

You would be better off with a
modulating one driving the radiators
directly

He wouldn't at all.

and the cylinder of the thermal store directly, with the
thermal store used only for hot water.

He has the heating already off the store in two zones.

This does not make optimal use of a condensing boiler, let alone a
modulating one.

It does. Only a cheaper, simpler more reliable boiler need be used.
