Wiring timer into indirect water tank

I have a honeywell aquastat on my indirect . It's wired into it on one of 4 zones on my taco switching relay. How can I wire a timer into this, so I can shut it off during night.

You would put the control contacts from the timer in series with the aquastat. You will need a timer where the contacts are isolated from whatever is powering the timer.
Note that a well insulated indirect probably won't cool enough to trigger a dhw call in 8 hours unless it was close to the cut in temp of the aquastat from a hot water draw or you are using some hot water during the night.3 -
You could do this and place a timer on the oil valve or gas valve to see if there is a significant reduction in burner operation over the summer months when there is no call or heat. Maybe 2 months with timer active and 2 months without timer active. I bet you won't see a very big savings as @mattmia2 indicated
