The Pentair UltraTemp 140 H/C (460958) is a heating and cooling pool and spa heat pump in almond. It delivers roughly 140,000 BTU of heat or 71,000 BTU of cooling, making it the right choice in hot climates where summer water temperatures climb above comfortable.
Key Features
- Heats and cools: Reverse-cycle operation drops water temperature in peak summer as well as extending the season in spring and autumn.
- 100% pure titanium heat exchanger: Corrosion-free performance and long service life in chemically treated water.
- Ozone-friendly refrigerant: Environmentally superior to older heat pump designs.
- AutoSet temperature control: Monitors water temperature and cycles the unit as needed, overriding the time clock to hold your setpoint.
- Dual thermostats: Separate pool and spa setpoints for precise control on combination systems.
- Emerson Copeland Scroll compressor: More efficient, durable and quieter than piston-driven compressors.
- Automation compatible: Works with Pentair automation control packages.

Frequently Asked Questions
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.
What's the difference between 460958 and 460959?
Colour only. The 460958 is almond; the 460959 is the same unit in black.
How does this differ from the 460934?
The 460934 heats only. This model heats and cools, and costs more accordingly.
What electrical supply does it need?
230V single-phase at 50 amps, on a dedicated circuit sized by a licensed electrician. Confirm your panel capacity before ordering.
How much space does it need?
The cabinet is roughly 39" x 31" x 44.5". Heat pumps also need generous unobstructed airflow around the coil — follow Pentair's clearance requirements in the installation manual.
Who should install it?
A qualified pool professional. Electrical connection must be carried out by a licensed electrician, and professional installation is generally required to validate manufacturer warranty coverage.
Frequently asked questions
How do I size a pool heater?
Heater sizing follows pool surface area, the temperature rise you want and how exposed the pool is to wind. A larger BTU rating heats faster and cycles less; an undersized heater runs continuously and still struggles on cold nights. Gas heaters also need a gas line and meter capacity that can supply their rated input.
What is the part number for this heater component?
Pentair lists this heater component under part number 460958. Quote 460958 when you cross-reference against your equipment manual, an existing part, or a parts diagram, so you are comparing the same revision.
What routine maintenance does a pool heater need?
Keep water chemistry balanced, because low pH and high calcium hardness are the two most common causes of premature heat exchanger failure. Beyond that: keep the cabinet clear of debris, check for rodent nests before each season, and have the burner and gas train inspected periodically.
How do I confirm this fits my equipment?
Match the part number stamped on the component you are replacing, or look it up in the parts list for your Pentair equipment. If your model or serial number is not named on this page, send it to us before you order and we will confirm the fit.
Is this the complete heater or a replacement part?
Check the title and the specification section above. Heater listings and heater component listings share the same part-number format, so confirm whether you are buying a full appliance or a single serviceable component before ordering.
Is there a warranty on this heater component?
It carries the standard Pentair manufacturer warranty. The terms are set by Pentair, and on some equipment the coverage only applies when a licensed professional performs the installation. Keep the receipt and packaging until you have confirmed correct operation.
