Jandy (a Fluidra brand, the same parent company as Zodiac) sells two current pool-heating lines: the JXi gas heater series and the JE titanium heat pump series. Both integrate with Jandy’s AquaLink and iAquaLink automation system, which is the brand’s real differentiator over Hayward or Pentair. Here’s how the models compare.
Quick answer
The Jandy JXi400N (400,000 BTU natural gas, 84% thermal efficiency, ~$3,999) is the best overall pick for most in-ground pools — it’s built to fit the same 2’x2’ equipment pad as a discontinued MasterTemp or Max-E Therm, so a replacement install often skips costly re-plumbing. Smaller pools or tighter budgets do well on the JXi260 (260,000 BTU, ~$3,499–$3,899). If you’d rather run a heat pump, the Jandy JE2500T (119,000 BTU, 6.2 COP, titanium exchanger) is the efficiency-focused pick, sized similarly to Pentair’s UltraTemp 140. One catch worth knowing before you shop: Jandy’s dealer network hides heat pump pricing far more than Hayward or Pentair do, so getting an exact quote usually means contacting an AquaLink-authorized dealer directly.

| Jandy JE2500T | Heat pump | 119,000 | 6.2 COP | ~$4,200–$4,600* |
| Jandy JE1500T | Heat pump | 72,000 | 5.5 COP | ~$2,800–$3,200* |
*Jandy heat pump pricing isn't published by most dealers — estimated range based on comparable Hayward/Pentair units at the same BTU/COP class (see our best pool heat pump pricing).
1. Jandy JXi400N — Best Overall
Jandy JXi400N Natural Gas Heater (400,000 BTU)
- Fits the same 2' x 2' pad as a discontinued Pentair MasterTemp or Jandy's own older Max-E Therm — Jandy markets it explicitly as a plumbing-compatible replacement.
- 117 lbs with a removable, rotatable top and flip-up electrical panel, which cuts service time versus older bulkier gas heaters.
- Automation-ready out of the box with Jandy's AquaLink systems and the iAquaLink mobile app.
- Low-NOx design that exceeds DOE efficiency requirements.
The JXi400N earns the top spot mainly on retrofit convenience: pool owners replacing an aging gas heater rarely want to pay a plumber to re-route pipes, and Jandy engineered the JXi’s footprint specifically to avoid that.

2. Jandy JXi260 — Best Value
Jandy JXi260 Gas Heater (260,000 BTU)
- Same 84%-efficiency C-Fin heat exchanger and low-NOx design as the 400N, just sized down for pools under roughly 20,000 gallons.
- Available in both natural gas and propane versions.
- Several hundred dollars cheaper than the 400N — right-sizing down instead of buying the biggest unit saves real money if your pool doesn't need the extra BTU.
If your pool is on the smaller side, there’s no efficiency penalty for stepping down from the 400N to the 260 — you’re just trading heat-up speed for a lower price, which is the right call for most residential above-ground and mid-size in-ground pools.
3. Jandy JE2500T — Best Heat Pump
Jandy JE2500T Heat Pump (119,000 BTU, 6.2 COP)
- Titanium heat exchanger resists corrosion in salt-chlorinated pools better than the copper exchangers used in gas heaters.
- 6.2 COP means roughly $1 of electricity returns about $6 of heat — in the same efficiency tier as Pentair's UltraTemp 140 (COP ~6.0), which we cover in our best pool heat pump guide.
- Dual thermostats for pool and spa, plus self-diagnostics on the digital control panel.
- Most online retailers won't list a price — expect to request a quote from an AquaLink-authorized dealer.
The JE2500T is the pick if you’re running the pool on electricity rather than gas and want Hayward-HeatPro-or-better efficiency with a titanium exchanger built for salt water — you’ll just need to work a little harder than usual to get an actual number out of a dealer.
4. Jandy JE1500T — Best for Small Pools & Spas
Jandy JE1500T Heat Pump (72,000 BTU, 5.5 COP)
- Right-sized for above-ground pools, small in-ground pools, and spas rather than large in-ground pools.
- Same titanium heat exchanger and digital controls as the larger JE-series units, just less BTU output.
- Lowest-cost entry into Jandy's heat pump line and AquaLink automation ecosystem.
For a spa or a pool under about 12,000 gallons, the JE1500T’s 72,000 BTU is plenty, and there’s no reason to pay for the JE2500T’s extra capacity you won’t use.
Why Jandy hides its pricing
Unlike Hayward and Pentair, which both list heater and heat pump prices openly on Amazon and big-box retail sites, most Jandy dealers show “call for price” or hide the number until checkout — especially on the JE heat pump line. That’s a deliberate dealer-protection policy rather than a sign the equipment is overpriced; independent retailers report JE-series street prices land in the same range as comparable Hayward and Pentair units once you get a quote. It does mean comparison-shopping Jandy takes an extra step most buyers of the best Pentair MasterTemp or Hayward vs. Pentair picks don’t have to bother with.
The bottom line
The Jandy JXi400N is the best overall Jandy pool heater for most in-ground pools, especially as a drop-in replacement for an aging MasterTemp or Max-E Therm. Downsize to the JXi260 for smaller pools, or go the heat-pump route with the JE2500T if you want titanium corrosion resistance and Pentair-UltraTemp-class efficiency — just budget extra time to get an actual price out of a dealer, since Jandy doesn’t publish heat pump pricing the way Hayward and Pentair do.
