Heat Banks provide Secondary Circulation
by the usual means, except the return tees
into the mains in (above flow switch). The heat
exchanger pump

Don't you mean the secondary circulation pump?

can be brought on by a
pipe thermostat fitted to secondary return
that will result in circuit being reheated once it
has dropped to stat setting. A clock should
always be used.

Sorry, I misread. The pipe stats can switch in the secondary circulation
pump and the DHW plate heat exchanger pump simultaneously. No sense in
having both running when the draw-off pipe is hot.
