Swimming Pool Heat Pumps

These systems usually operate on electricity and regarding efficiency; they are an excellent solution to keep warm your pool. They work with the same principle as HVAC (Heating Ventilation Air Conditioning); but instead of transferring heat to air, they transfer heat to the water in your pool.

Regarding inversion and installation; costs for acquiring swimming pool heat pumps vary depending on size and brand. In Florida; buying a heat pump may go from $1,700 to $3,800 without installation; while the entire system with installation may ascend over $8,000.

Concerning costs of operations; heating your pool with heating swimming pool systems increases %49 of your energy bill, which represents between $100 – $200 per month. And if you find affordable this amount, you aren’t taking into consideration the environmental impact in the equation.

Finally, in terms of maintenance; swimming pool heaters need to between $85 up to $1,800 a year for preventative/corrective maintenance. Keep in mind that maintenance will always depend on size and type of problem you find in your pump heater. 


Gas Pool Heaters

On the other hand, Gas Pool Heaters use either propane or natural gas to heat the water in your pool; just like if you were boiling water on your stove. Among its major advantages counts inversion and maintenance.

Buying a gas water heater in Florida costs around $1500-$2500; depending again on size. Also; you need to take into account if you have an attached spa you want to heat on, too.

In average; installation goes around $500-$1500. Regarding this last point; you need skilled labor to properly install gas pool heaters because risks of accidents are higher for this pool heater type.

However, they aren’t cheap neither: Running a gas pool heater costs around $200-$400 per month; and in terms of CO2 emissions, they are highly polluting and dangerous.
