Hum, I like that idea or beast of a boiler (38kW) cycles liike crazy
and overheats unless we wind it's stat well down when it only has the
HW to heat or just a little bit of CH. Solar would be nice to add
along with a woodburner so a thermal store or a heatbank sound like a
very good idea if it can soak up 38kW from the boiler as well...

The boiler size is probably overkill but not by much when you consider
it may have to heat 2 3 bed semis with external temps down to -10C and
a gale blowing...

Take the CH off the store using a Grundfoss Alpha pump. Heat the store
"directly" with 28mm piping. Put a TMV on the boiler flow and return to
maximise efficiency.

The store can take solar and stove input by adding coils to the bottom of
the cylinder.
