Quick answer: Jandy and Hayward both make solid gas heaters and heat pumps, but the comparison plays out differently on each side. On gas heaters, Jandy wins on confirmed price — the JXi400N runs about $3,999 versus the Hayward Universal H400FDN’s current $4,600-$5,100 (per Home Depot, Walmart, and PST Pool Supplies listings), both at 400,000 BTU and roughly 84% efficiency. On heat pumps, the matchup is genuinely uncertain: Jandy’s JE2500T is priced by dealer quote only, so its estimated $4,200-$4,600 (based on comparable Hayward/Pentair units) can’t be verified against Hayward’s openly-listed HeatPro HP21405T at $6,500-$7,000. Pick Jandy for the cheaper, confirmed gas heater or if you already run AquaLink automation; pick Hayward if you want to see an actual heat-pump price online before you commit.
Jandy (a Fluidra brand, the same parent as Zodiac) and Hayward both sell full residential gas-heater and heat-pump lineups, and both integrate with their own whole-pool automation systems. The catch: only one of these brands tells you what its heat pump costs before you call a dealer. Here’s how they actually compare.
Jandy vs Hayward at a glance

Gas heaters: JXi400N vs Universal H400FDN
Both flagship gas heaters are rated at 400,000 BTU and land around 84% thermal efficiency, so they’ll heat a large in-ground pool at essentially the same speed. Price and fit are what actually separate them:
- The Jandy JXi400N costs about $3,999 per current retail listings and, per Jandy’s own product literature, is engineered to fit the same 2’x2’ equipment pad as a discontinued Pentair MasterTemp or Jandy’s older Max-E Therm — a real advantage on a replacement install where re-plumbing adds cost.
- The Hayward Universal H400FDN now runs $4,600-$5,100 across Home Depot, Walmart, and PST Pool Supplies — noticeably higher than the roughly $4,589 this site tracked a few weeks ago — but it offers a cupro-nickel heat-exchanger option built for salt-chlorinated pools and sits on Hayward’s much larger service-and-parts bench.
For most straightforward gas-heater replacements, Jandy’s confirmed lower price makes it the easier value pick; Hayward earns its premium mainly through salt-water durability and easier local repairs. See our best Jandy pool heater guide for the smaller JXi260, and our best gas pool heater roundup for how both stack up against Pentair and Raypak.

Heat pumps: JE2500T vs HeatPro — a price comparison you can’t fully verify
This is where the two brands diverge structurally, not just on numbers. Hayward publishes its HeatPro HP21405T price openly on Amazon and other major retailers — currently $6,500-$7,000 for the titanium-microchannel model at a COP around 5.7. Jandy does the opposite: per Jandy’s own dealer network, the JE2500T (119,000 BTU, 6.2 COP, titanium exchanger) isn’t listed with a retail price anywhere, and most sites show “call for price” and route buyers to an AquaLink-authorized dealer instead. The $4,200-$4,600 figure quoted for it — here and on our own best Jandy pool heater page — is an estimate based on comparable Hayward and Pentair units at the same BTU/COP class, not a confirmed number.
That matters for a straight price comparison: if the estimate holds, Jandy’s JE2500T would undercut the HeatPro by $1,900-$2,800 while posting a higher COP (6.2 vs ~5.7). But you can’t verify that the way you can with Hayward’s listed price — you’d need an actual dealer quote first. See our pool heating cost guide for what the COP difference means in monthly electricity cost either way.
- Choose the Jandy JE2500T if the estimated price holds up on a quote and you want the higher COP — worth calling a dealer to confirm before you decide.
- Choose the Hayward HeatPro if you’d rather shop and compare a confirmed price online without contacting a dealer first.
Hayward HeatPro HP21405T (Heat Pump)
- 140,000 BTU, COP ~5.7, titanium exchanger.
- Price listed openly — no dealer quote needed to compare.
Automation: AquaLink vs OmniX
Both heaters tie into a whole-pool automation panel rather than offering built-in app control on their own — see our pool heater automation guide for how every brand’s system actually works. Jandy’s AquaLink (via the iAquaLink app) is the one named feature that stands out here: it supports Amazon Alexa and Google Assistant voice commands for basic tasks like setting the spa temperature. Hayward’s OmniX app focuses on phone-based scheduling and remote monitoring and doesn’t advertise voice-assistant support as a headline feature. If voice control specifically matters to you, that tips toward Jandy — otherwise the two systems cover the same core ground.
The bottom line
Buy Jandy if you want the cheaper, confirmed-price gas heater, you’re willing to call a dealer for a heat-pump quote, or you specifically want AquaLink’s Alexa/Google Assistant voice control. Buy Hayward if you want every price listed openly before you buy — especially on the heat-pump side, where Jandy simply won’t tell you a number online — or you want the wider bench of local service technicians.
