Quick answer
Jandy’s current gas-heater line, JXi, comes in three sizes — the JXi200N (200,000 BTU, 83% thermal efficiency), JXi260N (260,000 BTU, 84%), and JXi400N (400,000 BTU, 84%) — but only the two larger units are easy to actually buy: the 260N and 400N carry visible prices on Amazon and Walmart, while the 200N is mostly call-for-price or local-pickup-only, per listings at Sunplay and ePoolSupply. On the heat-pump side, Jandy’s JE-series splits into an older heat-only tier (JE1500T/72,000 BTU, JE2500T/119,000 BTU, and JE3000T/137,000 BTU) and a newer JE3000TR Pro Series unit (140,000 BTU, 6.3 COP) that adds a cooling mode — and several pool-equipment parts catalogs, including pool360.com’s own database, now flag the plain heat-only JE3000T as obsolete with no listed successor.
JXi isn’t one heater — it’s three, and the smallest one is the odd one out
JXi gets cited across this site’s Jandy coverage as the brand’s current gas-heater answer to Hayward’s Universal H-Series and Raypak’s lineup, but no page here has broken out all three sizes side by side. That matters because the smallest model doesn’t just scale down the BTU number — it also drops in efficiency and gets noticeably harder to buy.
| Model | BTU | Thermal efficiency | Where sold | Typical price |
|---|---|---|---|---|
| JXi200N | 200,000 | 83% | Local pickup / call-for-price only | Not published |
| JXi260N | 260,000 | 84% | Amazon, Walmart, pool-supply dealers | ~$3,450-$3,899 |
| JXi400N | 400,000 | 84% | Amazon, Walmart, pool-supply dealers | ~$3,999 |
JXi400N — Best Overall
Jandy JXi400N Natural Gas Heater (400,000 BTU)
- Fits the same 2' x 2' equipment pad as a discontinued Pentair MasterTemp or Jandy's own older Max-E Therm, per our best Jandy pool heater guide — a real retrofit advantage over switching to a heat pump's larger footprint.
- Widely stocked with a visible price on Amazon and big-box sites, unlike the smallest JXi200N below.

JXi260N — Best Value
Jandy JXi260N Natural Gas Heater (260,000 BTU)
- Same 84%-efficiency rating as the flagship 400N, just right-sized for pools under roughly 20,000 gallons.
- Also available in propane, and also stocked on Amazon with a published price.
JXi200N — the one you can’t easily just order
The JXi200N is the smallest JXi, rated 200,000 BTU — but it isn’t simply a scaled-down 260N. Jandy’s own published spec for the 200N lists an 83% thermal-efficiency rating, one point below the 84% shared by its two larger siblings. More practically: where the 260N and 400N both turn up with a checkout-ready price on Amazon and Walmart, the JXi200N mostly doesn’t. Sunplay lists it as in-store-pickup-only in Ogden, UT or Las Vegas, NV with no online price, and ePoolSupply and Pool360 both route it to a “call for price” listing. If a small pool or spa only needs 200,000 BTU, budget extra shopping time to track down an actual number rather than expecting the same Amazon-checkout convenience as the bigger JXi units.
Jandy JXi200N Natural Gas Heater (200,000 BTU)
- Slightly lower thermal-efficiency rating than the 260N/400N (83% vs. 84%).
- Harder to buy online — expect call-for-price or local-pickup-only listings rather than a published checkout price.
The JE heat pump line: one size is already obsolete
Jandy’s titanium-exchanger JE-series heat pumps are the brand’s electric alternative to the JXi gas line, and our best Jandy pool heater guide already covers the JE2500T and JE1500T as the current heat-pump picks. What that page doesn’t capture: there’s a third, larger heat-only size — the JE3000T (and its 3-phase commercial sibling, the JE3000T3) — and multiple pool-equipment parts databases, including pool360.com’s own catalog, now list it as obsolete with no identified superseded model. Jandy appears to be covering that 137,000+ BTU capacity class going forward with a different, newer unit instead: the JE3000TR Pro Series, which swaps the plain heat-only design for a heat/cool model rated 140,000 BTU at a 6.3 COP (80/80/80 AHRI conditions), still listed as “call for availability” rather than genuinely gone.
| Model | BTU | COP | Mode | Status (2026) |
|---|---|---|---|---|
| JE1500T | 72,000 | ~5.5 | Heat-only | Listed, dealer-quote pricing |
| JE2500T | 119,000 | ~6.2 | Heat-only | Listed, dealer-quote pricing |
| JE3000T / JE3000T3 | 137,000 | ~6.1 | Heat-only | Obsolete — no successor listed |
| JE3000TR (Pro Series) | 140,000 | 6.3 | Heat/cool | Current — "call for availability" |
This is the same heat-only-vs-heat/cool split we’ve already documented on Hayward’s HP50HA vs. HP50TA and Pentair’s UltraTemp 140 vs. 140 H/C — except here it’s tangled up with an actual discontinuation. If you’re comparison-shopping and see a plain “JE3000T” listed cheap on a used or closeout site, that’s old stock of a model several parts catalogs already consider obsolete, not a budget alternative to the TR.
Jandy JE2500T Heat Pump (119,000 BTU)
- The current mid-size JE pick for most in-ground pools, sized similarly to Pentair's UltraTemp 140.
- Most dealers hide this model's price online — expect to request a quote rather than check out directly.
Which Jandy JXi or JE model actually fits your pool
For most in-ground pools wanting a gas heater, the JXi400N is the easiest to buy and the one this site already ranks as Jandy’s best overall pick. Downsize to the JXi260N for smaller pools — both are stocked with real prices on Amazon. Only reach for the JXi200N if your pool or spa genuinely doesn’t need more than 200,000 BTU, and budget extra time to get a number out of a dealer rather than expecting an Amazon checkout. On the heat-pump side, the JE2500T remains the closest match to Pentair’s UltraTemp 140 on efficiency; skip any plain JE3000T listing you find, since that size has effectively been superseded by the heat/cool JE3000TR.

The bottom line
“Jandy JXi” covers three gas-heater sizes that don’t all sell the same way — the 200N is a full point less efficient than its siblings and consistently harder to find a price for, while the 260N and 400N are both easy Amazon buys. On the JE heat-pump side, the lineup isn’t static either: the 137,000 BTU JE3000T is flagged obsolete by multiple parts catalogs, with the newer heat/cool JE3000TR Pro Series stepping into that capacity class instead. Check the exact model suffix — not just the family name — before assuming you know what you’re buying or what it costs.
