220 vs 110v pump

[Jrimbri]

So I am in a weird situation. I have a heyward SP1510Z1XEHC 1HP motor it is currently running on 220v, but I am looking to get a pool heater and it seems running an additional 220v is out of the question due to the conduit size and they cant run it in the same conduit which means I'd have to break up pavers..

I may be wrong but from what I am seeing this pump can run on 110v. What would be the negatives of switching the pump to 110v since I have that outlet next to my 220v and then utilziing the 220v for the heat pump.

Is that possible? Sorry, I am just spit balling ideas.

J,

A heat pump takes a lot of current.. Are you sure the wires that you have now are large enough??

What size breaker does your heat pump require???

Thanks,

Jim R.

What heater?

Can you show pictures of everything?

Show the pump motor label.

Distance from main breaker panel to pool pump?

Main breaker size?

Wire size?

There is almost zero chance that your existing wires are big enough for a heat pump.

How far is the run from breaker panel to pool equipment pad?

They can tunnel under pavers with equipment.

What size is the conduit?

You might be able to pull out the old wires and pull in bigger wires for everything as long as you do not exceed the conduit fill level.

If you have 3/4" conduit, you can use (4) #6 copper THHN.

You can probably use (2) #6 for the hot wires, (1) #8 for the neutral and (1) #8 for the ground.

You can use a regular 60 amp breaker in the main panel and go to a subpanel.

Typically, you will use a regular 50 amp breaker for the heat pump and a 20 amp GFCI breaker for the filter pump.

The maximum continuous load is 48 amps for the pump and heat pump combined.

For example, a 140,000 btu/hr heat pump will use about 33 amps and that leaves 15 for the pump.

Maximum distance = 169 feet.

If the conduit is 1/2", you can't do it.

Note: Verify all plans with a local licensed electrical contractor/electrician before deciding what to do.
