Still, even buying multiple units will save you a lot of money when you compare that to spending $1500 to $2000 or more for a propane or natural gas pool heater.

Each Smartpool Sunheater package comes with 80 ft.² of solar panels. The panels are easy to install and only require a few simple tools. The Smartpool Sunheater features a direct flow system with one header hole for each heating tube.

Water is passed through the heating tubes using your existing pool pump and as water passes through the tubes, the sun heats the water before it is reintroduced to your pool.

The Smartpool WWS601P Sunheater Solar Pool Heater is getting great reviews from customers online. A number of customers said that using this solar pool heater, they were able to extend their swimming season by about two months.

Different Types Of Pool Heaters

 

Gas Pool Heaters

 

If you have natural gas service to your house, a natural gas pool heater would be an option. If you don’t have natural gas service, a liquid propane heater would be an alternative.

One of the main benefits of gas pool heaters is that they are a lot less expensive to purchase than an electric heat pump or a solar heating system. An electric heat pump my cost anywhere from $3000 to $5000 whereas a gas pool heater will be somewhere in the neighborhood of $1500.

A gas pool heater will also be less expensive to install than an electric heat pump. Having a professional install your gas pool heater will run you approximately $300 to $500 and that includes all labor and materials. Installation for electric heat pump can be 2 to 3 times that price.

Another benefit of gas pool heaters is that they work really well. You can raise the temperature of your pool by several degrees fairly quickly depending on the size of your heater.

Now for the drawbacks. Although gas pool heaters are effective and they are cheaper to purchase and install, the operating costs for gas pool heaters is substantially more than that of an electric heat pump.

Prices of natural gas, propane, and electricity fluctuate regularly, but on average it will cost 4 to 5 times more to heat your pool with a gas pool heater than with an electric heat pump.

 

Electric Pool Heaters

 

When it comes to electric pool heaters you have two options; electric resistance heaters, or heat pumps. Like gas heaters, electric resistance heaters are relatively inexpensive to purchase, but that’s where the similarities end.

The operating costs for electric resistance heaters can be quite expensive. Installation can be expensive as well because heavy duty wiring and large amperage circuit breakers are required.

Heat pumps are expensive to install but they are very inexpensive to operate. The monthly operating costs of heat pumps will generally be between $50 and $150.

Heat pumps work by taking heat from the ambient air and transferring that heat to the water which is why they are so energy efficient. A heat pumps energy efficiency is also the reason why this type of heater has become so popular in recent years.

Of course, there are drawbacks to this type of pool heater as well. In addition to being considerably more expensive to purchase and install, this type of heater works best when it is already warm outside.

During cooler weather, when you need to heat your pool more, it will take a lot longer to heat the pool and you may not even be able to get it up to your desired temperature.

 

Solar Pool Heaters

 

Solar pool heaters harness the energy from the sun to heat the water from your pool. This makes them very environmentally friendly and because energy from the sun is free, there is virtually no monthly operating costs with this type of heater.

Although this type of pool heater is very inexpensive to operate, one of the drawbacks is that they are somewhat expensive to purchase and install. Another obvious drawback is that if the sun is not shining brightly, you won’t be able to heat your pool very efficiently.

 

Choosing the Right Pool Heater

 

Choosing the pool heater that’s going to be best for you depends on a number of different factors. You’ll have to decide if you want to invest a little more money up front for savings in the long run in the form of lower monthly operating costs, or if you want to save money on the initial purchase and installation, you’ll have to be willing to pay a little more each month to operate the heater.

Your location and climate will also be a big factor in deciding what type of pool heater to buy. If you live in a cooler climate that doesn’t get a lot of sunshine, solar pool heaters and electric heat pumps won’t be the best choice. You’ll have to use an electric resistance heater or a gas heater.

 

Getting the Right Size Pool Heater

 

Pool heaters are designed to be able to heat a certain number of gallons per hour. To make sure you’re getting a pool heater that is the right size for your pool, you have to know approximately how many gallons of water your pool holds.

If you already know this, you’re ahead of the game. If you don’t know what the capacity of your pool is, some measurements and simple math will help you get the answer.

Start by figuring out the average depth of your pool. Measure the depth of the shallow end, measure the depth of the deep end, add these numbers together and then divide by two to get the average depth of your pool.

Take this number and then multiply it by the width of the pool and then multiply that figure by the length of the pool. This will give you the volume of your pool in cubic feet. Finally, take that figure and multiply it by 7.5 because there are 7.5 gallons of water in a cubic foot.

Sure, it takes a little bit of effort, but figuring out how many gallons your pool holds is not terribly difficult.

With all of this information in mind it’s time to start doing some comparison shopping. First decide which type of pool heater would be best, then go online and start comparing features, specifications, and pricing.

With a little bit of research, you will be able to find the best heater at the best price.

Shopping online also allows you to quickly research customer reviews to help you make your purchasing decision. If you can find a pool heater that is the right type of heater, at the right price, and is also getting great reviews from customers, then you’ve found the right pool heater for you.
