Pool heater BTU sizing chart (2026)
Undersized heaters run constantly, fail early, and can't hit target temp on cold nights. Oversized heaters cycle on/off too fast and shorten compressor life. Here's correct sizing by pool volume:
| Pool volume | Gas heater BTU | Heat pump BTU | Solar panel area |
|---|---|---|---|
| Under 10,000 gal (small) | 175,000 BTU | 55,000 BTU | 180–250 sq ft |
| 10,000–15,000 gal | 200,000 BTU | 65,000 BTU | 250–325 sq ft |
| 15,000–25,000 gal (typical 14×28) | 300,000 BTU | 100,000 BTU | 325–450 sq ft |
| 25,000–35,000 gal | 400,000 BTU | 125,000 BTU | 450–600 sq ft |
| 35,000–50,000 gal | 400,000–450,000 BTU | 140,000 BTU | 600–800 sq ft |
| Over 50,000 gal (oversized) | 2× units 400K each | 2× units 140K each | 800+ sq ft |
Rule of thumb: target pool size up by 10–15% for safety margin, especially in NE Florida winter. Solar panel area = 60–80% of pool surface area for full year-round use; 40–50% for warm-weather extension only.
10-year pool heater cost of ownership (2026 Florida)
Total cost over 10 years = install + (annual operating cost × 10) for a typical 14×28 NE Florida pool, 82°F year-round, no cover. Add a solar cover to cut every "annual" and "10-year" number by 40–70%.
| Heater type | Install cost | Annual operating | 10-year TCO (no cover) | 10-year TCO (with cover) |
|---|---|---|---|---|
| Solar (with gas backup) | $8,500 | $1,000 | $18,500 | $13,500 |
| Heat pump only | $5,800 | $2,300 | $28,800 | $15,800 |
| Hybrid (HP + gas backup) | $11,500 | $2,500 | $36,500 | $22,500 |
| Natural gas only | $5,500 | $3,100 | $36,500 | $21,000 |
| Natural gas + new line | $8,500 | $3,100 | $39,500 | $24,000 |
| Propane only | $6,500 | $4,700 | $53,500 | $31,000 |
| Electric resistance (avoid) | $2,500 | $6,500 | $67,500 | $38,000 |
Mid-range NE Florida estimates. South FL costs drop 20–30%; Northeast US costs rise 30–60%. Heat pump or solar+backup is the cheapest year-round option for nearly all use patterns.
Pool heater costs in Jacksonville & Northeast Florida (2026)
Northeast Florida is a strong pool heating market — long swim season, relatively mild winters, and active competition keep installer pricing about 5% below national average. Here's what's different about heating a pool here:
$5,800
Median heat pump install in Jacksonville
$1,800
Average annual operating cost (heat pump + cover)
25–40
Nights/winter below 50°F (heat pump slows)
2–4 yr
Typical solar payback period in NE FL
What's different about Jacksonville heating
Mild winters help. Jacksonville averages about 25–40 nights below 50°F per winter (vs. 90+ in Atlanta). Heat pumps work efficiently most of the year. The trade-off: those 25–40 cold nights cost 2–3× more per night to heat, which is why so many homeowners eventually add a gas backup.
JEA natural gas is competitive. JEA's NG rate (May 2026 ~$1.35/therm) is reasonable, making gas a viable backup or primary option. Many Jax neighborhoods have NG service already at the house — verify before quoting gas. New lines run $25–$50/foot from the meter.
Solar works well here. NE Florida averages 230+ sunny days/year. A properly sized solar system (60–80% of pool surface area in panels) can maintain 80–85°F year-round with minimal backup heat from gas or heat pump. Highest-ROI heating investment in the region — 2–4 year payback typical.
Salt water pools wear gas heaters faster. 78% of new Jax pools are saltwater, and salt water vapor accelerates corrosion of standard copper heat exchangers. Specify cupro-nickel heat exchanger on any gas heater for a saltwater pool — adds $400–$800 but extends heater life 30–50%.
The combo to ask about: Heat pump + solar pool cover. This is the cheapest year-round heating setup for a typical NE Florida pool — about $6,800 total install, $900–$1,400 per year operating, 10-year TCO ~$16,000. Add a small gas backup heater later if you want guaranteed warmth on the coldest 20–30 nights of winter.
Jacksonville pool heater costs by neighborhood (heat pump install, typical)
| Neighborhood / area | NG available | Typical install |
|---|---|---|
| Nocatee / St. Johns | Most lots yes | $5,500–$7,500 |
| Ponte Vedra Beach | Mixed | $6,000–$8,500 |
| Mandarin / Julington Creek | Most lots yes | $5,200–$7,200 |
| San Marco / Avondale / Riverside | Almost all yes | $5,500–$7,800 |
| Jax Beach / Atlantic Beach / Neptune Beach | Most lots yes | $5,800–$8,000 |
| Fleming Island / Orange Park | Most lots yes | $5,200–$7,200 |
| World Golf Village / St. Augustine | Limited / propane common | $5,500–$7,800 |
| Fernandina Beach / Amelia Island | Limited / propane common | $6,000–$8,500 |
How this ROI calculator works (methodology)
Our pool heater ROI estimates are built from a dataset of 7,000+ real homeowner heater installs collected 2024–2026 from licensed pool contractors across Florida, Texas, Arizona, Georgia, the Carolinas, and the Northeast. The calculator combines install cost data (by pool volume and heater type) with operating cost models based on heat-loss physics and current 2026 utility rates (NG, propane, electricity by region).
Install cost scales primarily with pool volume (which determines required BTU output) and gas line availability. Operating cost scales with pool surface area, climate zone, target temperature, swim months, screen enclosure presence, and solar cover usage. All four together can swing annual operating cost by 5–8× — which is why generic "$X per month to heat a pool" estimates are almost always wrong.
Baseline operating cost references (typical 14×28 pool, 82°F, NE Florida, year-round, no cover):
- Natural gas: $2,800/yr ($1.35/therm at 85% efficiency)
- Propane: $4,200/yr ($2.50/gallon equivalent)
- Heat pump: $2,300/yr (COP 5.0 above 50°F, COP 3.0 below 50°F, JEA $0.143/kWh)
- Solar + gas backup: $1,000/yr (gas backup runs ~15% of year)
- Hybrid (HP primary + gas backup): $2,500/yr
Adjustment factors applied: pool volume (linear), screen enclosure (×0.80), solar cover (×0.45), climate zone (NE FL 1.0, S FL 0.55, Atlanta 1.40, Boston 2.20), target temperature (78°F 0.65, 86°F 1.45), swim months (12=1.0, 9=0.55, 6=0.20, 3=0.05).
10-year TCO assumes no major repairs (a $400–$1,200 service event is typical at year 6–8) and stable utility rates (NG and electricity rates have averaged 2–4% annual increase historically). Last full data refresh: May 2026.

Pricing basics
1. How much does a pool heater cost in 2026?
Pool heaters cost $3,500–$15,000 installed in 2026, depending on type and pool size. By type: solar pool heating $3,500–$7,500, natural gas heater $3,500–$8,000 (add $1,500–$4,000 for new gas line if needed), electric heat pump $4,000–$8,500, hybrid heat pump + gas backup $8,500–$15,000. Larger pools need bigger BTU units that cost more. National median for a single-system install on a typical 14×28 pool is about $5,800.
2. How much does it cost to install a gas pool heater?
A natural gas (NG) or propane (LP) pool heater costs $3,500–$8,000 installed in 2026 for the heater alone, plus $1,500–$4,000 if a new gas line is needed. By pool size: small pools (under 15,000 gal) use a 200,000 BTU unit at $3,500–$5,500 installed; medium (15K–25K gal) use 300,000 BTU at $4,500–$6,500; large (25K–40K gal) use 400,000 BTU at $5,500–$8,000. Permits typically add $65–$250. Total turnkey for a typical 14×28 Jacksonville pool with existing gas line: $5,000–$7,000. With new gas line: $7,500–$10,000.
3. How much does a pool heat pump cost?
Electric pool heat pumps cost $4,000–$8,500 installed in 2026, by pool size: small pool (<15K gal) 65,000 BTU unit $4,000–$5,500; medium (15K–25K gal) 100,000 BTU unit $4,800–$6,800; large (25K–40K gal) 125,000 BTU unit $5,500–$8,500; extra large (>40K gal) 140,000 BTU unit $6,500–$10,500. Pad, plumbing, electrical, and start-up included. Top brands: AquaCal (premium), Hayward HeatPro, Pentair UltraTemp, Raypak. Most Florida homeowners pay $5,500–$6,500 turnkey for a quality 100K BTU unit on a 14×28 pool.
4. How much does solar pool heating cost?
Solar pool heating systems cost $3,500–$7,500 installed in 2026. Pricing depends on panel coverage: 50% of pool surface area in panels (minimum effective) $2,500–$4,500; 80–100% coverage (recommended for Florida year-round use) $4,000–$7,500. Includes solar panels (typically roof-mounted), automatic controller ($300–$600), check valve, mounting hardware, and pool plumbing tie-in. Top brands: FAFCO, Heliocol, iSwim, Aquatherm. Most Florida solar pool installs pay back in 2–4 years through saved gas/electric heating costs — among the highest-ROI pool investments.
5. What's the cheapest way to heat a pool?
Cheapest by lifetime cost (install + 10 years operating): solar heater with no backup ~$8,000 total — but only works 6–8 months/year in NE Florida. Cheapest year-round option is an electric heat pump ($5,800 install + $1,800/yr operating = $23,800 over 10 years). A solar cover ($200–$400) is the highest-ROI accessory of all — cuts heating cost 40–70% regardless of heater type, paying back in 2–6 months. For cheapest year-round Florida pool: heat pump + solar cover = $24,000 over 10 years vs $35,000+ for gas heater without cover.
6. How much does it cost to heat a pool in Jacksonville, Florida?
In Jacksonville, FL the annual cost to heat a typical 14×28 pool to 82°F year-round runs $800–$4,500 per year depending on heater type, screen enclosure, and pool cover. Heat pump only: $1,800–$2,800/year (struggles below 50°F). Natural gas heater only: $2,400–$3,800/year. Propane heater: $3,800–$5,500/year. Hybrid heat pump + gas backup: $1,950–$3,200/year and most reliable. Solar with gas backup: $700–$1,500/year (highest ROI but biggest install). Adding a solar cover cuts every number by 40–70%. Unheated pools in NE Florida swim May–October naturally at 75–88°F.
Operating costs
7. How much does it cost to operate a gas pool heater per month?
Operating cost for a natural gas pool heater varies sharply by month in NE Florida. December–February (heaviest use): $400–$700/month to maintain 82°F on a 14×28 pool. March and November: $150–$300/month. April–October: typically $0–$80/month because Florida pools warm naturally. Annual total for year-round use: $2,400–$3,800. Propane (LP) costs 50–60% more than NG. Adding a solar cover cuts monthly costs by 40–70%. JEA natural gas rate (May 2026): roughly $1.35/therm; a 300K BTU heater uses about 3 therms per hour at full burn.
8. How much does it cost to run a pool heat pump per month?
An electric pool heat pump on a typical 14×28 NE Florida pool costs $80–$200/month to maintain 82°F when outdoor temps are above 50°F. Below 50°F the heat pump runs longer and less efficiently, pushing cost to $200–$350/month. Annual cost year-round: $1,800–$2,800 without a cover, $900–$1,400 with a solar cover. Heat pumps work by transferring heat from outdoor air into the pool — they typically deliver 5×–6× the heat per dollar of electricity vs. an electric resistance heater. JEA's average residential rate (May 2026) is $0.143/kWh; a typical 100K BTU heat pump draws 5–6 kW continuously when running.
9. How much does it cost to heat a pool year-round in Florida?
Heating a Northeast Florida pool to 82°F year-round costs $700–$4,500 per year depending on heater type, screen enclosure, and pool cover. Best to worst by annual cost: solar with gas backup $700–$1,500, hybrid heat pump + gas $1,950–$3,200, heat pump only $1,800–$2,800, natural gas only $2,400–$3,800, propane only $3,800–$5,500. A solar pool cover ($200–$400) reduces total heat cost by 40–70% — the highest-ROI pool accessory bar none. Screen enclosures cut heating cost by an additional 15–25% by reducing wind heat loss.
10. How much does pool electricity cost overall (including heater)?
A typical Florida pool with electric heat pump and standard equipment uses 4,500–8,500 kWh/year of electricity, costing $640–$1,210/year at JEA's $0.143/kWh rate. Breakdown: variable-speed pump 1,800–3,000 kWh ($260–$430), heat pump 2,000–4,500 kWh ($285–$645), salt cell 400–600 kWh ($55–$85), LED lights 50–150 kWh ($7–$22). Switching from single-speed to variable-speed pump cuts pump consumption 50–70% — Florida code requires variable-speed on new pools. Adding a solar cover cuts heat pump consumption by 40–70%.
11. Does a solar cover really cut pool heating cost in half?
Yes — and often by more. A standard solar cover (clear bubble blanket, $200–$400) reduces pool heat loss by 40–70% by blocking evaporation, which accounts for 60–75% of all pool heat loss. Annual heating savings on a typical 14×28 NE Florida pool: $800–$1,800/year reduction. Payback period: 2–6 months. Solar covers also reduce chemical use (less evaporation = less chemical loss) and water use (less makeup water). Downsides: must be manually removed before swimming and replaced after (5–10 min); needs replacement every 2–4 years from UV damage. Hard to find a higher-ROI pool product.
Heater types & comparisons
12. What's the difference between a gas pool heater and a heat pump?
Three key differences: (1) How they heat — gas heaters burn natural gas or propane and dump combustion heat directly into pool water (fast: 1–2°F/hr); heat pumps extract heat from outdoor air and concentrate it into pool water (slower: 0.5°F/hr but very efficient). (2) Operating cost — heat pumps cost 35–55% less per BTU delivered when outdoor temps are above 50°F; gas works at any temperature. (3) Temperature range — heat pumps lose efficiency below 50°F (a problem in Dec–Feb NE Florida cold snaps); gas heats fine at any temp. Best Florida setup: heat pump as primary, gas as backup for cold snaps.
13. Should I get gas or heat pump for my Florida pool?
For NE Florida year-round use, heat pump wins on total cost of ownership. 10-year TCO comparison for a typical 14×28 Jacksonville pool: heat pump $5,800 install + $19,000 operating = $24,800. Natural gas $5,500 install + $28,500 operating = $34,000. Heat pump saves ~$9,000 over 10 years. Exception 1: if you have free or extremely cheap natural gas (some Jax neighborhoods do), gas can match heat pump cost. Exception 2: if you want fast heating for occasional weekend use (heat to 88°F for a Saturday party), gas heats 3× faster. Exception 3: if you have backup power needs during outages, propane is independent of grid. Best of both worlds: hybrid system.
14. What is a hybrid pool heater system?
A hybrid pool heater combines an electric heat pump (primary heating, 80–90% of annual use) with a gas heater (backup for cold snaps and fast heating, 10–20% of use). Install cost $8,500–$15,000 — about 50–80% more than either alone. Annual operating cost $1,950–$3,200 in NE Florida — typically the lowest of any year-round system. Best for homeowners who want guaranteed pool temp year-round including Dec–Feb cold snaps, want the option to heat fast for parties, and have the budget for both systems. About 12% of new NE Florida pool installs go hybrid; most upgrade later when they realize heat pumps struggle in January.
15. How long does each type of pool heater last?
Pool heater lifespan in Florida by type: gas heater (NG or LP) 8–15 years (corrosion from chlorinated water vapor is main failure mode); electric heat pump 10–18 years (compressor is main failure point); solar panels 15–25 years (panel itself; controllers and valves 8–12 years); hybrid systems 10–15 years (whichever component fails first). Saltwater pools shorten gas heater life by 30–40% due to accelerated corrosion — install a cupro-nickel heat exchanger version for salt pools. Annual maintenance ($150–$300) extends lifespan 30–50%. Florida humidity accelerates outdoor electrical failures vs. drier climates.
16. What size pool heater do I need (BTU)?
BTU sizing depends on pool volume, desired temperature rise, and time-to-heat target. Simplified Florida sizing: small pool under 15,000 gal — gas 200,000 BTU or heat pump 65,000 BTU; medium 15,000–25,000 gal — gas 300,000 BTU or heat pump 100,000 BTU; large 25,000–40,000 gal — gas 400,000 BTU or heat pump 125,000 BTU; extra large over 40,000 gal — gas 450,000 BTU or heat pump 140,000 BTU. Undersized heaters run constantly, fail early, and can't maintain temp on cold nights. Oversized heaters cycle on/off too fast, shortening life. Better to slightly over-size than under-size.
17. Are solar pool heaters worth the cost in Florida?
In Florida — usually yes, but only as part of a hybrid system. Solar pool heating costs $3,500–$7,500 installed and pays back in 2–4 years through saved gas/electric costs. The catch: solar alone can't maintain 82°F in NE Florida Dec–Feb (you need gas or heat pump backup for those months). Best Florida configuration: solar panels covering 80–100% of pool surface area + small gas backup heater for cold snaps. Total install $7,500–$13,000, annual operating cost $400–$1,200 — the lowest year-round cost of any system. Roof-mounted panels are most common; ground-mount works if you have a sunny lot.
Installation & setup
18. How long does it take to install a pool heater?
Most pool heater installs take 1–2 days for the equipment portion plus 1–4 weeks total elapsed time including permit. Heat pump install: 4–8 hours (electrical work + plumbing tie-in + pad). Gas heater install with existing line: 4–8 hours. Gas heater with new gas line: 1–3 days (gas company runs the line, separate trade). Solar install: 1–2 days (roof mounting + plumbing + controller). Permit timelines NE Florida: Duval 1–3 weeks, Clay 1–3 weeks, St. Johns 2–5 weeks. Most reputable contractors handle permits — confirm in writing.
19. Do I need a gas line for a pool heater?
Only for gas heaters — heat pumps and solar don't need gas. If you're going gas and don't already have a line near the pool equipment pad, expect to add $1,500–$4,000 for the gas company to run a line. Cost factors: distance from existing meter to pool pad (usually $25–$50/foot), trenching difficulty, and whether the meter needs upgrading for higher BTU demand. Natural gas (NG) requires utility connection — JEA serves most of Jacksonville. If your home doesn't have NG service, you can install propane (LP) with a 250–500 gallon underground tank — tank install adds $2,500–$5,500 separately.
20. Where should the pool heater be installed?
Pool heaters install on the equipment pad alongside the pump and filter, typically 5–25 ft from the pool. Code clearances: gas heaters need 3 ft clearance on all sides plus 4 ft above for venting; heat pumps need 24 inches on intake side and 36 inches above (poor airflow kills efficiency); solar panels mount on the roof (south-facing optimal in Florida). Avoid placing heaters under overhanging trees (leaf debris) or in low spots that flood. Florida Building Code requires manufacturer-specified clearances or the install fails inspection. Confirm clearances at site walk-through before quoting.
21. Do I need a permit to install a pool heater?
Yes — every Florida county requires a permit for new pool heater installation. Typical 2026 permit costs: Duval $65–$165, St. Johns $125–$275, Clay $85–$225, Nassau $95–$245. Gas heaters require an additional gas permit ($45–$95). Permits trigger inspection of: gas line pressure test, electrical bonding (heat pumps), proper venting (gas), clearances, and equipment pad mounting. Owner-permitted installs are technically allowed but rarely approved without a Master Plumber's signature for gas work. Most reputable contractors pull the permit in their name — verify in the contract.
22. Can I install a pool heater myself?
Heat pumps and solar — technically yes, practically risky. Gas — no, not legally. Gas pool heater installs in Florida require a licensed plumber or pool contractor by law (Chapter 489 FS); DIY gas work voids manufacturer warranty AND insurance coverage. Heat pump DIY install: $700–$1,500 in equipment costs saved, but most warranties (Hayward, Pentair, AquaCal) require professional install for full coverage. Solar DIY: most feasible for handy homeowners with roof access — $1,500–$3,000 in install labor savings. Best DIY-friendly: solar panels (just plumbing, no gas/high-voltage); worst: gas (legal + safety + warranty issues).
Performance & efficiency
23. How fast can a pool heater warm up a pool?
Heating speed varies dramatically by type. Gas heater (properly sized): 1–2°F per hour — a 14×28 pool from 65°F to 82°F takes 8–17 hours of continuous run. Heat pump: 0.5°F per hour above 50°F outdoor temp, 0.25°F per hour below 50°F — same heat-up takes 17–34 hours (or longer in cold weather). Solar (full sun): 0.3–0.5°F per hour during peak hours only — solar heats slowly and only during daylight. For occasional weekend swimming, gas wins on speed. For year-round 'always warm' use, heat pump wins on cost. Solar wins on operating cost but needs days to heat from cold.
24. What's the most efficient pool heater?
Solar pool heating is the most efficient by far — once installed, it delivers ~95% of received solar energy directly into the pool for essentially free (just pump electricity). Among purchased-fuel options, heat pumps have COP (Coefficient of Performance) of 5–6, meaning 5–6 units of heat delivered per unit of electricity used. Gas heaters convert 82–95% of fuel energy to heat (95% for premium condensing models like Pentair MasterTemp HD). Electric resistance heaters (rarely used in Florida) are 100% efficient but expensive to run — the worst choice for pool heating. Most efficient real-world year-round system: solar + heat pump + cover.
25. Will a heat pump work in Florida winter?
Yes, but with limits. Pool heat pumps work efficiently down to about 50°F outdoor temperature. Below 50°F efficiency drops sharply — at 40°F a typical 100,000 BTU heat pump only delivers about 60,000 BTU, and at 35°F it can struggle to maintain pool temp at all. NE Florida sees overnight lows below 50°F about 25–40 nights per winter; heat pumps will run those nights but cost 50–80% more per night during cold periods. Best practice: pair heat pump with a backup option (gas heater, or just accept lower pool temp for 1–3 weeks per year). Newer 'low-ambient' heat pumps work down to 35°F but cost 15–25% more upfront.
26. Does a pool enclosure reduce heating costs?
Yes — by 15–25% annually in NE Florida. A screen enclosure reduces wind-driven heat loss (the second-biggest heat loss after evaporation), keeps water temperature more stable overnight, and reduces the difference between water and air temperature. Combined with a solar cover, an enclosed pool can run 40–60% lower heating cost than an open uncovered pool. The math: open pool with heat pump $2,400/year heating; enclosed pool with heat pump + cover $900/year heating. Annual savings $1,500. Doesn't justify building an enclosure for heating alone, but it's a meaningful side benefit of an enclosure built for other reasons.
Maintenance & lifespan
27. How often does a pool heater need to be replaced?
Typical Florida pool heater replacement cycle: gas heater every 8–15 years, heat pump every 10–18 years, solar panels every 15–25 years (panels themselves; controllers/valves every 8–12 years). Saltwater pools cut gas heater life 30–40% — use cupro-nickel heat exchanger models for salt pools. Signs of needed replacement: heater cycling on and off frequently, water not reaching set temp, visible corrosion or rust at heat exchanger, unusual noises (banging, clicking), error codes that recur after professional service. Replacing a heater proactively at year 10–12 typically saves the cost of an emergency mid-summer failure repair.
28. What maintenance does a pool heater need?
Annual maintenance recommended for all pool heaters; cost $150–$300 per year in Jacksonville. Gas heaters: clean burner tray, check gas pressure, inspect heat exchanger for soot/scale, verify carbon monoxide venting, replace pilot/ignitor as needed. Heat pumps: clean evaporator coil (critical for efficiency), verify refrigerant pressure, check fan motor, clean condensate drain, inspect electrical connections. Solar: inspect panels for cracking/leaks, flush plumbing, check controller and check valve, verify drain-back. Skipping annual service typically reduces heater lifespan by 30–50% and increases operating cost 10–25% in the meantime.
29. Why is my pool heater not working — common problems?
Top 6 pool heater failure causes by frequency in Florida: (1) Heat exchanger scale buildup (especially saltwater pools) — heater runs but pool doesn't warm; (2) Faulty pressure switch — heater won't ignite even with proper water flow; (3) Bad ignitor/pilot (gas) — heater clicks but won't light; (4) Low refrigerant or bad compressor (heat pump) — runs but pumps cold air, no heat into water; (5) Tripped high-limit safety — heater shuts off after 5–10 minutes; (6) Clogged air intake (heat pump) — leaves, debris, or pollen blocking airflow. Most issues diagnosable in 30–60 min by a licensed pool tech; repairs $150–$800. Replacements over 10 years old often more economical than repair.
30. Is a pool heater covered by homeowner's insurance?
Most Florida homeowner's policies cover the pool heater as part of "pool equipment" under personal property or detached structures coverage. Typical coverage: lightning strike (yes, common in FL), accidental damage (yes), theft (yes if installed property), fire (yes), flooding (only with flood policy). NOT covered: normal wear and tear, freeze damage (rare in NE FL but does happen), poor maintenance, manufacturer defects (covered by warranty instead). Document your heater with photos and serial number, save receipts and maintenance records, and verify pool equipment coverage limits with your insurer — many policies cap pool equipment at $3,000–$5,000 which won't replace a premium heat pump.
