Sizing comes first.The right heater is set by your pool's surface area and the temperature rise you want, and by the flow your pump and plumbing deliver. Start with the heater size calculator; we confirm it on site before quoting.

These are the manufacturer's published terms. Terms can depend on the installer, the dealer program and where the heater was bought, and they change without notice, so we confirm the exact term for your install on the written quote.
Titanium doesn't corrode in pool water, so it's the standard on quality heat pumps and the reason a heat pump can sit on a salt pool for years without exchanger trouble. It costs more, which is why it's rare on gas heaters, and the ETi 400 is the exception here.

Most to least forgiving of salt and unbalanced water.

Every figure on this page comes from these manufacturer documents. We re-open each one and match the model number, capacity and efficiency before the date moves. How we verify.
Manufacturers revise terms without notice. Treat this page as a starting point and confirm the current terms before you buy. If something here is out of date, tell us and we'll fix it.
Parts: 2 years. Compressor: 5 years. Heat exchanger: 5 years. These are the manufacturer's terms as published; warranty terms change and can depend on the installer and the channel, so we confirm the exact term for your install on the written quote.
The JRT4001R is rated at 160,000 BTU/hr heating output. Heater size comes from your pool's surface area and the temperature rise you want, not from gallons, and the pump and plumbing have to deliver the flow the heater needs. Use our heater size calculator for a starting number, and we confirm it on site before quoting.
Only through a compatible automation system. The JRT4001R has no Wi-Fi of its own, so the app control comes from the automation system it's wired to.
