Can anyone provide some advice for me.
I was wondering if I would be able to connect my new Hayward HP21254T heater to the same timer (Intermatic T104P3) as my pool pump (USQ1152 - 115/230 volt 1.5 hp). Currently, the pump is the only thing attached to the timer. The timer is connected to a 60 amp breaker panel on the outside wall.
Any help would be appreciated.

A heat pump uses a lot of power. You can't just connect it to the timer. You probably need an electrician to make sure that it's wired correctly.

Unless there is a special situation you really don't need this heater on a timer. It will only run when the pump runs as the heater has a water flow switch.
