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 460733. Quote 460733 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.
