I think you can use Type536 itself but you need to make sure of a
few things. First, make sure that you account for the capacitance of
the collector and use a short time step. If you run a pump to put
hot fluid into the collector then turn off the pump, the liquid is
going to get hot very very quickly (both in the simulation and in
reality). Second, you need to fully define your control strategy.
For example what happens after you extract the liquid; does another
batch go in and start heating?<br clear="none">

If you have access to the TESS Controls library you can use
Type980 (on/off time calculator) for the timer between "filling" and
"extracting" If you don't then I think you can use an integrator
(Type24) and the built-in variable TIME.<br clear="none">
