Raypak vs Hayward
Quick answer: Raypak and Hayward both make gas pool heaters and heat pumps, and both are widely sold and serviced. We do not rank either. Compare the specific models you are quoted on output at your conditions, efficiency, exchanger material, warranty terms, gas or electrical needs and local parts and service support, then decide with your installer.
Why we don't pick a winner
Brand comparisons online often turn into rankings based on a few reviews or on which model a writer happened to test. Real-world outcomes depend far more on correct sizing, installation, water chemistry and service than on the logo. Both makers offer multiple product lines that change over time, and a given model from either can suit or mismatch your pool. So instead of a verdict, this page gives you a neutral way to compare the two quotes in front of you.
Step 1: line up equivalent models
Make sure you are comparing the same type and size class: gas with gas, heat pump with heat pump, similar input or output ratings. A quote for a 400,000 BTU/h gas heater from one maker against a 266,000 BTU/h unit from the other is not a brand comparison; it is a size comparison. Run the pool heater size calculator first so you know the range you need.
Step 2: compare the spec sheets line by line
| Item to compare | What to look for |
|---|---|
| Rated input or output | Matches your sizing; heat pumps at your cool-month air temperature |
| Efficiency or COP | Thermal efficiency for gas; COP at stated test conditions for heat pumps |
| Fuel and conversion | Natural gas, propane or both; conversion kit needs |
| Heat exchanger | Material and any stated water chemistry limits |
| Flow range | Minimum and maximum flow versus your pump |
| Venting and clearances | Outdoor or indoor approval; distances required |
| Electrical | Voltage, amperage, breaker size |
| Controls | Digital display, automation compatibility, remote options |
| Sound | Published sound level for heat pumps |
| Low-temperature limit | Minimum operating air temperature for heat pumps |
Use the current spec sheets from each maker's website or your dealer, not old forum posts, because model generations change.
Step 3: read both warranties side by side
Look at length of coverage for parts, heat exchanger and labour; whether professional installation and registration are required; what water chemistry conditions void coverage; and whether residential and commercial use are treated differently. Warranty differences can matter more than small spec differences.
Step 4: ask who services each locally
Call two local service companies and ask which brands they repair most, how quickly they get parts and what common issues they see. A brand your local technicians know well can mean faster fixes. Availability differs by region, so a national reputation may not reflect your town.
Step 5: compare installed price and running cost
Installed price includes gas or electrical work, which may differ by model if one needs more gas input or a bigger breaker. Then use the operating cost calculator with each model's efficiency or COP. Over several seasons, a small efficiency difference can matter for heavy users and barely register for light users.
Worked example: two gas heater quotes
Figures below are illustrative examples (2026-10-29), not quotes or guarantees.
Assumptions: Quote 1 is a 266,000 BTU/h input heater at 84% efficiency for $4,800 installed. Quote 2 is a 260,000 BTU/h input heater at 82% for $4,500 installed. Output: about 223,000 vs 213,000 BTU/h, so heat-up speed is similar. Delivering 12 million BTU a month for 4 months at $1.40 per therm: Quote 1 ≈ 571 therms ≈ $800 a season; Quote 2 ≈ 585 therms ≈ $820. The $300 price gap would take about 15 seasons to recover through efficiency, so warranty and service support become the deciding factors.
Heat pumps from either maker
For heat pumps, focus on output and COP at the lowest air temperature you plan to swim in, the minimum operating temperature, defrost capability, sound level and electrical requirements. Compare using the pool heat pump size calculator result. Two units with the same headline rating can perform differently in cool air.
What reviews can and cannot tell you
Owner reviews are useful for spotting patterns such as recurring error codes or difficult service access, but they over-represent unhappy buyers and rarely mention water chemistry or installation quality. Weigh them lightly against spec sheets, warranty terms and local service advice.
Installation and safety
Whichever brand you choose, gas connections and venting must be done by a licensed HVAC or pool professional, and 240 V circuits by a licensed electrician. Never attempt DIY gas work. Follow pool chemical labels to protect the heat exchanger.
Other makers
Other manufacturers also sell pool heaters and heat pumps. The same checklist works for any pair or group of models. See best pool heaters for the full how-to-choose process.
Questions to ask your dealer
- Which model generation is this, and when was it released?
- What exchanger material does it use, and what chemistry ranges does the maker require?
- Is the unit compatible with my automation system and salt chlorinator?
- What is the typical lead time for common parts?
- Who handles warranty claims, you or the manufacturer?
Comparing service experiences
Service experience is personal, but you can collect useful evidence. Ask neighbours with heated pools what brand they own and how repairs went. Ask your pool supply store which parts they keep in stock for each brand and how long special orders take. Ask your installer how many of each brand they have installed in the past year. Patterns from local sources tell you more about likely downtime than national ratings. Write the answers down in a short table so the comparison stays factual rather than based on memory.
FAQ
Is one brand more reliable?
We have no independent data to say so; installation and chemistry dominate reliability.
Can I mix brands of heater and pump?
Usually, if flow and controls are compatible; your installer confirms.
Should I choose based on price alone?
Price, running cost, warranty and service together give a better answer.
