Does the UltraTemp 140 really cool the pool?

Yes. It runs in reverse to chill water at about 71,000 BTU, which helps in peak summer heat. Cooling output is about half its heating output, so expect slower temperature drops than warm-ups.

How many gallons can it heat?

Pentair rates the 140,000 BTU model for roughly a 20,000-gallon pool in a warm climate, less in cooler air or with a spa. Size it with a heat-loss calculation for your pool and cover.

What power does it need?

It is a 220V unit that needs a dedicated circuit sized by an electrician. It also needs clearance around the cabinet for airflow, so plan the pad location before buying.

Does it work with my automation system?

It is compatible with Pentair automation control packages, and the listing says it works with all automated control packages. Check your controller's model for the specific wiring and protocol.

Is the titanium exchanger worth it?

A 100% titanium exchanger resists corrosion from treated water far better than cupronickel, which is the main reason to pay more for this line. It matters most in salt or heavily dosed pools.

What reviewers say

Owners of Pentair heat pumps generally report reliable heating and quiet operation, and the titanium exchanger is a common reason buyers pick this line. Reception of the H/C cooling function is thinner, and some owners note the price and the need for professional installation.

What people mention

BuildPraisedOwners like the corrosion-resistant composite cabinet and titanium exchanger for holding up to pool chemicals.
NoisePraisedThe Copeland scroll compressor is described as noticeably quieter than older piston units.
CoolingMixedThe reverse-cycle cooling works, but at about 71,000 BTU it is weaker than the heating side.
ControlsPraisedThe LCD board with full-word messages and dual thermostats is seen as easy to set up and read.

What does H/C mean?

Heat/Cool. The unit reverses its refrigeration cycle to remove heat from the water, which is genuinely useful in hot climates where pools become uncomfortably warm in midsummer.
