Description
A heat pump is one of the most efficient ways to heat a pool, and the Pentair UltraTemp 460932 is built to make the most of it. It delivers about 110,000 BTU per hour of heating capacity with a COP of 6.1.
UltraTemp is Pentair's residential/light-commercial heat pump line with a 100% titanium heat exchanger, scroll compressor, R410A refrigerant, corrosion-resistant composite cabinet and AHRI-certified BTU/COP ratings; H/C models add cooling. In this guide we explain how it works, how to size it, what electrical service it needs and how to get the best performance in your climate.
Quick Answer: What Is the Pentair UltraTemp 460932?
The Pentair UltraTemp 460932 is an electric heat pump pool heater rated at about 110,000 BTU/hr with a COP of 6.1. It uses a refrigerant cycle to move heat from the outdoor air into the pool water, delivering several units of heat for every unit of electricity it uses.

How a Heat Pump Pool Heater Works
A heat pump works like an air conditioner in reverse. A fan draws outdoor air across an evaporator coil, where refrigerant absorbs heat from the air. A compressor raises the refrigerant's temperature, and a heat exchanger, usually titanium for corrosion resistance, transfers that heat to the pool water. The refrigerant then cycles back to collect more heat.
Efficiency is measured by the coefficient of performance (COP). A COP of 5 means the heater delivers five units of heat for every unit of electricity, so each kilowatt-hour can deliver roughly 5 x 3,412 BTU to the water. Heat pump ratings are commonly published at 80 F air, 80 percent humidity and 80 F water; output drops as the air gets cooler, and most units are designed to operate down to around 45 to 50 F.
How to Size a Pool or Spa Heater
Raising one gallon of water one degree Fahrenheit takes about 8.33 BTU. Multiply your gallons by 8.33 and by the temperature rise you want to find the total heat needed, then divide by the heater's output to estimate hours. Heat pumps heat more gradually than gas, so they are best at maintaining temperature. Size for your pool's surface area, your coolest swimming month and how warm you like the water. In cooler regions, choose a larger model or pair it with a cover.
At its rated 110,000 BTU/hr, running 24 hours, the approximate temperature rise before heat losses is:
Real-world results depend on air temperature, humidity, wind and whether you use a cover. A cover can make a dramatic difference by reducing evaporation, the largest source of heat loss.

Installation and Electrical Requirements
This heater requires a dedicated electrical circuit (208-230V 1-Phase, 26 A rated at 80/80/80 (70 A max breaker)). A licensed electrician should size the wire and breaker and provide a service disconnect as required by code. The heater is plumbed after the filter and before any chlorinator, and it needs adequate water flow for the flow switch to engage.
Heat pumps need open airflow: leave the clearances shown in the manual on all sides and above the unit, avoid enclosing it under decks or in tight corners, and place it on a level pad that allows condensation to drain away. Condensation is normal and can look like a leak on humid days.
Professional installation is recommended.
Maintenance Tips
- Keep pool chemistry balanced to protect the heat exchanger and element.
- Keep the coil fins clean and clear of leaves, grass clippings and debris; rinse gently with a garden hose.
- Make sure the condensate can drain freely.
- Have a technician inspect electrical connections annually.
- In freezing climates, drain the heater and plumbing when the pool is closed for winter.
Best Climates for Heat Pump Heating
Heat pumps shine in the South and Sun Belt, including Florida, Texas, Arizona, the Gulf Coast and Southern California, where warm, humid air provides plenty of heat to harvest for most of the year. In the North, they work well for the core summer season, and many owners pair one with a gas heater for spring and fall or for a spa. Models with a cooling mode are popular in the hottest regions, where pool water can become uncomfortably warm in mid-summer.
What's Included and Compatibility
This listing is for the Pentair UltraTemp 460932. Unions and automation accessories may be sold separately.
Ideal for:
- In-ground pools and pool/spa combos in warm to mild climates
- Owners replacing gas heat with lower operating-cost electric heat
Heat Pump vs Gas vs Electric Resistance Heat
Many owners combine heat sources: a heat pump to hold the pool temperature through the season and a gas heater for quick spa heat or cold snaps. Covers reduce heat loss no matter which heater you choose.

Frequently Asked Questions About the Pentair UltraTemp 460932
How much will the Pentair UltraTemp 460932 raise my pool temperature?
At about 110,000 BTU/hr running all day, roughly 15.8 F per day for a 20,000-gallon pool before losses. A cover helps significantly.
Do heat pumps work in cold weather?
They work best above about 50 F. As the air cools, capacity and efficiency drop, and most units stop heating near their low-temperature limit.
Are heat pumps cheaper to run than gas?
In warm climates, usually yes, because they move heat rather than burning fuel. Your savings depend on local electricity and gas prices.
What electrical service does it need?
208-230V 1-Phase, 26 A rated at 80/80/80 (70 A max breaker). Have a licensed electrician install a dedicated circuit and disconnect.
Is water dripping from the unit normal?
Yes. Heat pumps produce condensation as they pull heat from humid air. It can be several gallons per hour on humid days.
