Heat Pump Questions

[BigTallGuy]

I would not put anything bigger than a 40 amp breaker on a circuit with 8 gauge wire.

Specific wire sizes mandate breaker size.

Is this circuit a dedicated circuit meaning the Heat Pump is the only thing on the circuit, or do you have other items running off of it like your pool pump etc.?

How long is the actual circuit from the Service Panel to the unit?

If you have a long run, do like Ben said and go with a #6 wire and a 50 amp breaker.

Thanks for the info. It is a dedicated run just under 60' which is why I was thinking the 40a/8ga setup would be fine, but I wanted to double check here to make sure I wasn't missing something obvious (or maybe not so obvious :-) ).

Also, does anyone see any issues with the 1.5"x2" adapter on the inlet/outlet for the heat pump? The heat pump has a min/max gpm rating of 35/75 and my current pump is rated @ 90 gpm, but that is an unrestricted rating. By the time the water flows through the hoses and the sand filter to the heat pump it is within the 75 gpm rating and I don't believe running it through the 2" piping in the heat pump should cause it to drop enough to take it below the minimum. Any thoughts? Thanks.
