Hayward and Pentair are the two biggest names in pool heating, and most buyers end up choosing between them. They both make excellent gas heaters and heat pumps — so the real question is which brand fits your pool, budget, and existing equipment. Here’s how they compare head to head.
Hayward vs Pentair at a glance
| Factor | Hayward | Pentair |
|---|---|---|
| Flagship gas heater | Universal H-Series (H400FDN) | MasterTemp 400 |
| Flagship heat pump | HeatPro (COP ~5.5) | UltraTemp (COP ~6.0) |
| Efficiency | Excellent | Class-leading |
| Noise | Low | Lowest |
| Automation | OmniLogic | IntelliCenter |
| Price | Lower | Higher |
| Service/parts | Very common, cheaper | Common, pricier |
Gas heaters: MasterTemp vs Universal H-Series
Both flagship gas heaters land around 84% thermal efficiency and cover the same 250k–400k BTU range, so raw heating power is a wash. The differences are at the margins:
- The Pentair MasterTemp 400 lights faster from a cold start, runs slightly quieter, and has a clean, modern control panel.
- The Hayward Universal H-Series H400FDN is a little easier to service, is compatible with more setups out of the box, and usually costs less.
For most owners the Hayward is the better value; choose the MasterTemp if quiet operation and fast cold-starts matter to you.
Pentair MasterTemp 400 (Gas)
- 84% efficient, 400,000 BTU, quick cold-start.
- Quiet operation and IntelliCenter-ready.

- 84% efficient, 400,000 BTU, easy to service.
- Cupro-nickel exchanger option handles salt pools.
Heat pumps: UltraTemp vs HeatPro
Here Pentair pulls slightly ahead on paper. The UltraTemp posts a rated COP near 6.0 with an automatic defrost cycle, giving it the lowest running cost and a wider operating range. The HeatPro answers with a COP around 5.5, a titanium exchanger, and a noticeably lower price.
- Choose the Pentair UltraTemp if you want maximum efficiency and the widest shoulder-season range.
- Choose the Hayward HeatPro if you want nearly the same efficiency for meaningfully less money.
Hayward HeatPro HP21404T (Heat Pump)
- 140,000 BTU, COP ~5.5, titanium exchanger.
- Quiet, corrosion-proof, salt-friendly.
The bottom line
Both brands are safe, top-tier choices — there’s no wrong answer. Buy Hayward if you want the best value and easy, affordable service down the road; the Universal H-Series and HeatPro do 95% of what Pentair does for less. Buy Pentair if you want the quietest, most efficient equipment and a fully automated IntelliCenter pool. The most common tie-breaker is simple: match whichever brand already runs your pump and automation, and installation stays clean.
