Thanks! That's the plan now

Hi everyone, I bought a new electric heat pump and I will do the plumbing on it. The heater has 2" fittings but all my plumbing on my existing filter / pump is 1 1/2" Should I just run 1 1/2 to the heater and then right at the heater install a 2x1 1/2 fitting or should I install a 2 x 1 1/2 fitting back at the pump and run all 2 inch pipe and fittings to the heater? Thanks for any advice you can give
