Feel free to get in touch
The Pentair UltraTemp 140 (460934) is a high-performance pool and spa heat pump in almond, rated at roughly 140,000 BTU. Rather than burning fuel, it moves heat from the surrounding air into your water — which is why a heat pump costs a fraction of gas or electric resistance heating to run.
Key Features
- 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: Standard feature that 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.
- Digital controls: Clear readout and simple setpoint adjustment.
- Automation compatible: Works with Pentair automation control packages.

Frequently Asked Questions
Does this unit cool as well as heat?
No. The 460934 is heat-only. If you need cooling as well, the UltraTemp 140 H/C is the heat/cool version — 460958 in almond, 460959 in black.
What's the difference between 460934 and 460964?
Colour only. The 460934 is almond; the 460964 is the same unit in black.
How does a heat pump compare to a gas heater?
A heat pump moves existing heat rather than generating it, so running costs are dramatically lower. The trade-off is slower heat-up and reduced output as air temperature falls, which makes it best suited to extending the season rather than heating a cold pool quickly.
What electrical supply does it need?
230V single-phase, on a dedicated circuit sized by a licensed electrician. Confirm your panel capacity before ordering.
Does it work with pool automation?
Yes — it is compatible with Pentair automation control packages.
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 460934. Quote 460934 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.
