wiring for a heat pump(new IG pool)question

[Poolsean]

Most heat pumps will be 220 volts and not more than 60 amps of service for their largest heat pump. Usually this will be #6 AWG. If you research the various manufacturers, you'll be able to tell how much service you need.
I can tell you that the Aqua Cal H155 (123,000 btus) requires 40 amp service due to the efficiency.

Bury a couple large conduits so you can fish wires, extra pipes, whatever you think.

Advice worth repeating. Plastic electic conduit is dirt cheap. Run a cheap non-biodgradable string or small rope through it ahead of time too. I'd be sure to run one to the opposite side of the pool in case you end up wanting to put some lighting, change hut, or whatever at some time. This saves a huge headache later on.

We did the same thing you did. I wanted a heat pump but did not have the cash to put it in initially. We had the pool equipment slab made big enough to put in the heatpump. We also ran a intermatic 100amp sub panel out to the pool.
