Unveil the key to ensuring your pool heater lasts for years.

Have you ever wondered about the lifespan of a pool heater? Today, we’re taking you on a unique tour of our boneyard, which is essentially our heater graveyard, to discuss the remarkable longevity of our heaters.

As we stroll through the boneyard, you’ll notice a common theme among these retired heaters—the manufacturing date. Almost all of them are between 15 to 20 years old. This reveals a crucial fact: our pool heaters boast one of the longest serviceable lives in the industry. You can count on enjoying your pool for a solid 15 to 20 years with our reliable heaters.

Recently, we encountered an extraordinary case. A residential customer had been using their heater for a staggering 35 years. Yes, you read that right, 35 years! While the heater had developed a minor refrigerant leak, it could have been repaired. However, the homeowner opted for a replacement.

Inspecting the installation photos, you’ll notice a homeowner who diligently performed planned maintenance on their entire system. This meticulous care included corrosion prevention inside the heater—an essential practice for extending the life of any heating system.

If you’re interested in installing a pool heating system that matches the remarkable longevity of our ambient service heaters, don’t hesitate to call or email. Our team is here to ensure your pool stays warm and enjoyable for years to come.

A look at two more of the most popular pool-heating options.

It’s time for part two of our side-by-side comparison of all your different Florida pool heating options. If you missed part one where we covered the pros and cons of electrical resistance heaters and natural gas/propane heaters, check it out here. This time, we’re focusing on the air source heat pump and the PH90 GeoThermal pool heater. 

The air source heat pump has an evaporator coil that is susceptible to damage from the salt air. If you have a pool on the coastline, you may not want this type of pump. However, it is a pretty efficient option.

Here’s how it works: It takes in air through the coils, sucks the heat out of the air, ejects the heat through the coil, and the condensing coil has a titanium tube heat exchanger that produces about 150,000 BTUs per hour. For every dollar you spend on heating, you’re getting six dollars worth of heat. To heat your average pool, it only costs around $1,300 to maintain 84 degrees. That’s much lower than the $6,000 average for pools heated with natural gas or propane systems.

We’re here in the boneyard today to go over the different types of heaters that you can use to heat your pool in Florida. There are four different types of pool heaters that we’ll cover. We’ll go through the pros and cons of the first two today, show you how they work, and detail the maintenance costs of each.

We’ll start with the electrical resistance heater. It has two heating elements that stick down into a reservoir and heats water as it flows through. As you apply power to the coils, they glow and heat the water. 

They are very susceptible to chemical imbalances, however, so they end up having to be replaced quite often. They produce 37,000 BTUs per hour and a coefficient of proficiency of 1.0. That means for every dollar you spend, you get one dollar’s worth of heat. It’s not a great choice for bigger pools; it’s better for spas.

Next, we have the natural gas and propane heaters. It produces 400,000 BTUs at 84% efficiency. That means you’re only producing 336,000 BTUs per hour. It has a small footprint, and it’s not affected by the outside temperature no matter how cold. 

A weakness of this is that as pool water flows through the cupronickel heat exchanger, it’s also very susceptible to chemical imbalances. When the pool water gets to a saturation point, it will stain your pool surface with copper. You have to be extra careful with this one. In a typical residential pool, to heat the pool year-round, it will cost you $6,000 per year for natural gas but $14,000 per year with propane. It does have a small footprint and provides a lot of heat

In order to know what size of heating system you need for your pool, you will need to know how many gallons it holds. For the equations you’ll need to use to estimate this amount, please refer to the video above starting at 0:15.

After you know how many gallons your pool holds, you can then find the BTUs that your pool will need each day. You can see the equation for this at 0:37. This calculation requires using a recovery factor, which is the number of degrees that the heating system must be able to raise the pool each day to maintain a temperature when heat is lost overnight.

As I mentioned before, a pool that is not heated would match the outside average air temperature. So, if you wanted to keep a pool heated to 86 degrees in January when the average temperature is only 60 degrees, you will have to raise it 26 degrees just to counter the air temperature.

To calculate the recovery factor after this temperature difference is considered, there are many factors to evaluate: Average wind speed, shade from trees and buildings, if a blanket is used, where return locations in the pool are located, and depth, which is a large factor.

The pools that you see in the video at 3:00, although they look much different in terms of surface size, only have a 200,000-gallon difference. The depth of the pools greatly impacts the number of heaters required for the competition pool versus the diving pool. This is because there are less BTUs needed to heat a deeper pool with a smaller surface area compared to a shallower pool with the same volume. In this example, the competition pool requires eight heaters while the diving pool requires only three.

When comparing the differences between air source heat pumps and water source heat pumps, what is the first thing that comes to mind? The answer is simple: One uses air and one uses water. Yet there are even more differences between these two heat sources that may not be so obvious.

During my recent lecture about swimming pool heating systems, the room was set to a comfortable 75 degrees. However, this same temperature would be far less comfortable if you were in a pool, because water transfers heat more efficiently than air. A lack of humidity translates to a lack of efficient heating.

When you use a water source, the temperature is more consistent. Bodies of water experience temperature change less rapidly than air. So which heating method is most beneficial for maintaining a pool’s temperature?

Geothermal heat sources are a very effective option for heating pools, because they can be installed indoors while an air source cannot. Since they don’t need any air flow, you have more options of where to position the system.

Geothermal heat sources also offer great performance, low operating costs, and a life expectancy of up to 15 or 20 years if serviced regularly. They are also capable of cooling.

The primary drawback to this heating method is that it has a higher installation cost.

If you have any additional questions about geothermal heating, please feel free to contact me. I look forward to speaking with you soon.

In continuation of my course, “Choosing the Right Swimming Pool Heating System,” today I’ll be discussing the function and mechanics of geothermal heat pumps.

When you hear the term ‘geothermal,’ what do you think of?

‘Geo-’ means ‘earth,’ and ‘-thermal’ means ‘heat.’ Old Faithful geyser, the popular tourist destination at Yellowstone National Park, is just an example of the kind of power that can be harnessed for human use. The vapor and steam that erupt from the geyser is high-grade geothermal energy.

Another high-grade geothermal area of interest you might have heard of is Warm Mineral Springs in North Port. The water there bubbles at 87 degrees Fahrenheit and flows out into a lake, issuing a strong sulfur smell.

At Symbiont, we use low-grade geothermal power. When the sun heats the Earth, that heat is stored in groundwater, and we use our technology to operate heating and cooling systems by harnessing this phenomenon.

At 1:40 in the video above, you’ll see a map of the United States indicating the temperature of groundwater in wells that range in depth from 50 to 150 feet. In Florida, the average temperature of the water is 75 degrees. In the winter, this heat acts as a great source for our heat pumps. In the summer, this same temperature acts as a great sink, or a place to put heat back into the ground, if you’re using our cooling system.

As a recap for how a geothermal heat pump works, refer to 2:25 in the video above. Similar to the air pump we’ve discussed before, our heat pump differs only in that it has two water coils instead of the fan. It still has a compressor, refrigerant flow control, the condenser, and the evaporator. The refrigerant flows through, changing states depending on where it is in the cycle.

If you have any questions about geothermal heat pumps, please feel free to contact me. I’d be glad to help answer any questions you have.
