Hi,

Just a general point, I wonder if it would be better to run the
radiator return through the heatbank lower coil, with a pipestat and
bypass valve across it.

Then as the return temperature from the radiator rises, the valve
would open so excess heat is dumped into the heat bank, reducing the
flow temperature to the boiler to promote efficiency.

If there was a sudden demand on the radiators, the lower temperature
would close the valve so the boiler sees a lower return temperature.

Otherwise the return temperature to the boiler would slowly rise until
the boiler cuts out but the heat stored in the lower part of the heat
bank would help keep the radiators hot and delay the time until the
boiler fires again.

There's probably some more potential in this idea if I could think of
it

The rads directly off the heat bank. The return of the rads runs through
a
plate heat exchanger and then back to the heat bank. The return from the
heat bank back to the boiler runs through the plate heat exchanger. The
returning rad water would cool the returning boiler water lower the
temperature. They may be case where this may not occur, but these
occurrences would be few and far between.


This gets more and more stupid.
Now you are adding an additional
heat exchanger to the mix.

You clearely do not understand.

You've forgotten the plastic pipe under the garage floor to preheat it
all.

About the only sensible thing you have said.
