Pool Heaters 101

February 12, 2019


Here in South Florida the weather is so nice in the winter months but the water in your pool is chilly, so you have been thinking about expanding your pool season by adding a pool heater to your swimming pool. What type of pool heater is good for your pool and how much does it cost? In this blog we are going to try to answer these questions. Let us start by saying that for South Florida we recommend electric pool heaters or heat pumps and here is why.


There are three types of pool heaters: electric, gas and solar.


Electric: Pool Heat Pumps have a lower cost to operate than gas, only solar heaters are better in that regard, and are more expensive to install than gas heaters. They are our choice for South Florida taking into consideration that many houses aren’t retrofitted for gas and you probably need a permit to install solar panels in your roof.


Pros: Inexpensive to operate


            No emissions

            Last up to 20 years with proper maintenance

Cons: More expensive upfront

           Doesn’t work well in colder temperatures

           Heats the water slowly

Cost: $2500 to $4000


Gas: Gas heaters are the one that heat the water faster, they are less expensive to install than pool heat pumps or solar heaters but the monthly cost to operate is significantly higher compared to an electric heater, plus your house needs to have a gas line or tank.


Pros: Heats the water fast

            Less expensive up front

            Low emissions       

Cons: Costs a lot to operate

            Your house needs to have a natural gas line or a propane tank

            Not eco-friendly

            Short lifespan (5 years on average)

Cost: $1500 to $3500


Solar: Solar heaters are the least effective when heating a pool, it depends on how much sun there is that day plus you have to install panels on the roof or backyard and they take a lot of space. There is no monthly cost to run it, but the initial installation can be expensive.


Pros:  Uses a free source of energy

            Lasts about 15 years

            Good for warmer climates


Cons: Heats the water slowly

            Only works if the sun is shining

            Takes a lot of room in your backyard or roof

Cost: $3000 to $4000


In conclusion Pool Heat Pumps are our choice of swimming pool heaters for South Florida. The price is going to depend on the size of your pool as well as the brand.
