How To Choose The Right Intex Pool Heater

Your pool heater is a vital machine in keeping your Intex pool water swimmable for you and your family even during the cold months. It keeps your pool warm for a better swimming experience.

If you’re having a hard time choosing your Intex pool heater, then you might consider answering these questions first:

  • What’s the overall size of your Intex pool?
  • What type of pool heater are you looking for?
  • How much are you willing to spend on your Intex pool heater?
  • How much use are you expecting to get out of it?

Once you’re able to come up with answers to those questions, it’ll be easier for you to make a decision on what pool heater you should purchase.

Types Of Intex Pool Heaters

Intex pool heaters are often measured in BTU or British Thermal Unit. If a higher BTU is indicated that means the quicker that machine can heat your swimming pool.

Gas Pool Heaters

Using gas heaters is one of the most common ways you can heat an Intex pool as it’s fairly easy to use. And can heat your index pool quickly.

Most gas heaters use either propane gas or natural gas to heat your swimming pool.

The BTU that you need will highly depend on your pool size. The larger it is the higher BTU your pool requires for your gas heater.

Like any typical machine that uses gas, these heaters emit air pollution and can be expensive to operate as they can cost you anywhere from $300 to $600 per month. Of course, you also have to pay for the upfront cost of acquiring a gas heater that’s anywhere between $1,000 to $1,500.

Heat Pumps

Heat pumps work by either using both electricity and your surrounding air or by electricity and a water source.

Heat pumps are a more efficient way to heat an Intex pool and will only cost $50 to $150 to operate monthly.

The main drawback of using heat pumps is that they’re more expensive to acquire than a gas heater. Their price usually ranges from $2,000 up to $4,000.

Solar Heating System

Using a solar heating system is another great way to heat your Intex pool. It can be expensive to set up but a solar heating system for your pool is much affordable to install than a solar heater for your house. And it won’t require you to spend on any monthly operating expenses.

It works by utilizing your installed solar panels to transfer heat from the sun to your pool by letting your pool water pass through them.

But what if it’s raining or during the night when there’s no sun to heat my solar panels?

For this one, you might have to rely on another pool heater to heat your pool.

A solar heating system does not heat the pool quickly as a gas heater would.

Solar Covers or Blankets

An inexpensive way to heat your pool is by utilizing solar covers or blankets. These are made of plastic material that’s designed to retain the heat from the sun or the heat produced by your pool heater.

For those living in warmer climates, using solar covers to heat your pool might be enough so you won’t have to buy an Intex pool heater anymore.

But if the solar covers are not enough to give you the right temperature you want for your Intex pool, then you may opt to purchase a more powerful pool heater and supplement it with a solar pool cover for better heat retention.

  1. We just purchased a Coleman pool which is similar to the Intex pool. I am told by pool supply companies that any pool heater other than solar will not work as the pipes will melt. Could you recommend the adjustments that would be required to the pipes and fittings to allow for a heater to be used. Thank you
