Quick answer: Raypak and Pentair are both top-three pool-equipment brands, and Raypak wins on price across the board. The AVIA 264K gas heater (around $3,890) adds built-in Wi-Fi and still costs less than the similarly sized Pentair MasterTemp 250 (around $3,700 without app control built in), and the Crosswind V 8550 heat pump undercuts Pentair’s UltraTemp 140 by roughly $650-$900 ($4,550-$5,100 vs. $5,200-$6,000) while now matching it on COP (both around 6.0, since Raypak retired the older, lower-COP R8450ti). Pentair still wins on automation depth and cold-weather range — UltraTemp’s automatic defrost cycle extends its operating window, and IntelliCenter is the deepest smart-pool ecosystem on the market. Pick Raypak to save money on either equipment type without giving up heat-pump efficiency, or Pentair if you already run IntelliCenter or need the widest shoulder-season range.

Raypak and Pentair are two of the three brands (alongside Hayward) most pool professionals install first, and both build full gas-heater and heat-pump lineups for residential pools. Here’s how they compare head to head.

Gas heaters: AVIA vs MasterTemp

Matched by BTU class, the Raypak AVIA 264K and Pentair MasterTemp 250 (250,000 BTU) both land around 82-84% thermal efficiency, so raw heating power is close. The real differences:

If you want the biggest available gas heater rather than the mid-size match, Pentair’s MasterTemp also scales up to a 400,000-BTU flagship (around $4,789) — see our full Pentair MasterTemp size guide for all three sizes. Choose Raypak if built-in Wi-Fi is worth paying a little more for; choose Pentair if you want the lowest sticker price or already own IntelliCenter automation.

Heat pumps: Crosswind V vs UltraTemp

Pentair and Raypak are now close to tied on efficiency, and Raypak still wins clearly on price. The UltraTemp 140 posts a rated COP near 6.0 with an automatic defrost cycle that extends its operating range into colder shoulder-season air, at $5,200-$6,000. Raypak’s Crosswind V 8550 — which replaced the older, lower-COP R8450ti — is tested to a comparable 6.0 COP under AHRI 1160 conditions for a meaningfully lower $4,550-$5,100. See our pool heating cost guide for what a small COP gap actually means in monthly electric-bill dollars.

Raypak Crosswind V 8550 (Heat Pump)

Lowest price here · 138,000 BTU, COP 6.0 · ~$4,550–$5,100
  • 138,000 BTU, COP 6.0 under AHRI 1160 testing, titanium exchanger, built-in Wi-Fi/app control.
  • Meets Florida's state-mandated 4.0 minimum COP for pool heat pumps sold in-state.

The bottom line

Both brands are safe, top-three choices — there’s no wrong answer. Buy Raypak if price is the deciding factor on either gas heaters or heat pumps, or if you want Wi-Fi control without paying for a separate automation system. Buy Pentair if you want the widest shoulder-season heat-pump operating range or you’re already invested in IntelliCenter automation. Weighing a third option? Our Hayward vs. Pentair and Raypak vs. Hayward comparisons cover the other two matchups, and our best gas pool heater roundup lines up all three brands’ natural gas models side by side by BTU size and price. Gulfstream’s HE-RA lineup — now sold under Pentair — undercuts the UltraTemp on price at a similar COP if efficiency-per-dollar is your priority, and Jandy is the fourth major brand if you’re already running its AquaLink automation. Whichever brand you land on, a fitted pool heater cover is a cheap way to protect either cabinet between uses. Still deciding gas vs. heat pump first?
