Things to Consider Before Buying a Reliable Pool Heater
Before you start signing any checks, you need to know whether your equipment pad can accommodate another piece of gear. A heater is most often installed after your filtration system, so there needs to be at least 3–4 feet of room for the heater to fit into your rig.
Otherwise, you may need to invest in some rearrangement renovations.
Best pool heaters
Heat pumps
These are the most common and efficient types of swimming pool heaters to use in Florida. A heat pump takes the heat from the outdoor air, then transfers it to the pool water via a compressor and a heat exchanger.
Heat pumps are usually costlier than gas heaters. They consume significantly less energy and have a longer lifespan. Their efficiency decreases when the temperature drops to 50 degrees Fahrenheit.
Heat pumps are not effective in freezing temperatures; this issue is less concerning for residents of Florida.
Gas heaters
These can heat a pool very quickly, but do so at the expense of either natural gas or propane. They’re not as efficient as heat pumps, but the startup cost is much less. Gas heaters work well if you have a natural gas line in your house.
They are effective for small pools that heat quickly. They are suitable if you do not intend to keep your pool heated all winter.
What is the best pool heater to buy?
Heating? Cooling? Or Both Some heat pump models don’t just heat water, but are also able to bring the water temperature down in warmer months.
So, if your water is too cold in the winter and too hot in the summer, you might want to consider one of these options! Just look for a model notated as a “Heat and Cool” or “H & C” unit.
When choosing a pool heater, it’s important to consider the type of pool you have. If your pool uses salt water, you may wonder what the best pool heater is for this setup.
Intended Use and Size
Do you plan to keep the pool warm year-round, or just in the winter months? Are you using your pool every day in December, or just once in an ice-blue moon?
Is the heater dedicated to a backyard pool, or is it also providing auxiliary heat to your hot tub? Or maybe you’re not sure of the best pool heaters for Florida?
When considering the right pool heater for your needs, there are several important questions that can help you figure out the size and functionality you require. If you plan to use the heater only occasionally, a gas heater might be a suitable option for you, as it can provide quick heating when needed without being overly expensive.
However, if you have a larger pool or anticipate using the heater more frequently, you may want to think about upgrading to a larger heater that can accommodate your needs more effectively.
It’s essential to discuss these factors to choose the best pool heater in detail with your pool professional to ensure you find the most appropriate heater that meets both your size and usage requirements.
