Installing a pool heater in Bradenton costs $3,500 to $9,500 including the electrical or gas run. The choice between a heat pump and a gas heater is not about which is better, it is about how you swim. Heat pumps win for owners who keep the pool warm all season. Gas wins for owners who want it warm this weekend. See our design service, and for related reading, see which upgrades pay back.
Heat Pump Versus Gas Running Costs on the Gulf Coast
Short answer
A heat pump maintaining a screened Bradenton pool at 86F through the cool months typically runs $70 to $160 a month. A propane heater doing the same job runs three to four times that. Gas reaches temperature in hours; a heat pump takes a day or more.
The mechanism explains the gap. A heat pump moves existing heat from the air into the water, so it delivers several units of heat per unit of electricity, but it depends on there being warmth in the air to move. Below roughly 50F ambient its output collapses. Bradenton sees those conditions on a handful of nights each winter, which is exactly why heat pumps suit this climate better than they suit north Florida.
Gas creates heat by burning fuel, so its output is unaffected by air temperature and its cost per degree is fixed and high. The right use case is a pool you heat occasionally: family visiting for a week in January, an evening in the spa. Owners who buy gas expecting to keep the pool at 88F from November to March are typically shocked by the first propane bill.
Why a Solar Cover Changes the Heater Sizing Conversation
Short answer
An uncovered pool loses the majority of its heat through evaporation off the surface, not through the walls. A solar cover typically cuts heat loss by 50 to 70 percent, which can drop you a heater size and pays for itself in a single season.
This is the most under-discussed part of pool heating in Florida. Heating an open pool in February is largely heating the air above it. The cover is inconvenient and unattractive and it is also the highest-return item in the entire heating conversation. A screen enclosure helps but does not substitute for it; a cage cuts wind-driven evaporation, not the evaporation itself.
We size heaters on covered-pool assumptions where the owner will actually use a cover, and on open-pool assumptions where they will not, because an undersized heater on an open pool will run continuously and never reach setpoint. Being honest about whether you will really roll a cover on and off is worth more to the sizing than any other input.

| Type | Installed cost | Monthly running cost | Time to heat 10F | Best for |
|---|---|---|---|---|
| Electric heat pump | $4,500 - $8,000 | $70 - $160 | 24-48 hours | Season-long warmth, lowest running cost |
| Natural gas heater | $3,500 - $6,500 plus line run | $250 - $600 | 8-14 hours | Occasional use, fast heat, spa |
| Propane heater | $3,500 - $6,000 plus tank | $350 - $800 | 8-14 hours | No gas main available, occasional use |
| Solar panel array | $4,000 - $9,500 | Near zero | Weather dependent | Extending shoulder season, roof space available |
| Solar cover alone | $150 - $600 | Zero | Retains rather than adds | Every pool, alongside any of the above |
Running costs assume a screened residential pool held at 86F during Bradenton's cool months.
