It can be a real pain to heat an Intex pool, but it’s not impossible. In fact, you can use basic math and an above-ground heater to get your water up to the right temperature. Here are the steps you’ll need to take:

## Know your water per hour.

Your pool will lose water through evaporation, and this rate is your water per hour. So, how do you calculate it? Well, first you’ll need to know the volume of your pool. If you don’t know that off-hand, here are a few things you can use as a measurement guide:

- A standard-sized residential pool is about 15 feet by 30 feet (460 square feet)
- An average size above-ground spa is 6 feet by 12 feet (72 square feet)

Once you have that number handy, divide it by 60 and then multiply by .15 to get the total gallons lost per hour. For example: if your in-ground swimming pool holds 1000 gallons and has an area of 100 ft^2 then 1000/60 x .15 = 15gph

## Know the water capacity of your pool.

Measuring the water capacity of your pool is a simple task.

It’s important to know the volume of your pool because this will help you determine how much fuel it takes to heat it.

To measure the volume of your pool, fill up a plastic measuring cup with water and set it down in one corner of the pool. Then, stand back and look at the distance from that corner to where your marker pen or pencil has been placed on a vertical surface inside the pool (like its wall). This distance will be used as an approximation for how deep your pool is when full.

In order for these measurements to make sense later on when we’re talking about heating methods and costs, let’s convert them into percentages so we can easily see what percentage each measurement represents compared with all others combined:

## Know the average temperature of your pool.

It’s important to know the average temperature of your pool and environment, as well as the average temperature of your water.

That way, you can use a heater that’s designed to raise the temperature by X degrees within Y minutes, where X is your target change in temperature and Y is the amount of time it takes for that change to happen. For example, if you have an Intex pool and want it to heat up from 68°F / 20°C to 80°F / 26°C in 4 hours (so your kids won’t freeze their little swimmer toes), then you need a heater that can raise its target temperature by 3 degrees per hour (or 1 degree every 20 minutes).

## Know the ambient temperature of your environment.

The first thing you need to do is figure out the average temperature of your pool. This is pretty easy—you can use a thermometer or just take an educated guess based on experience. If it’s a hot day, then your pool will be hotter than usual and if it’s cold out, it’ll be colder. Once you know this number, subtract it from the ambient temperature of your environment (the temperature of the air around your pool). This gives you the number of degrees that need to be added in order to get things up to where they should be.

Now go ahead and put those numbers into action!

## Choose an above-ground heater.

The next step is to choose an appropriate heater. If you have a small, shallow pool, it’s probably not necessary to invest in a very powerful electric heater. You can save money by simply buying one with less wattage and installing it yourself. If your pool is large or deep, however, consider investing in a more powerful model that will heat up the water faster than a smaller model would be able to do so on its own.

When shopping for an above ground pool heater, be sure to check out any needed accessories as well (such as hoses or wiring adapters). You may also need some special tools for installation such as pliers or screwdrivers if your new unit does not come preassembled from the factory (which means it’ll need some assembly before installation).

## You can heat an Intex pool using simple math and an appropriate heater

There are a few things to consider before you choose a pool heater for your Intex pool. First, you need to find out the surface area of your pool. You can use a tape measure or even just eyeball it if that’s all you have on hand (it’s okay!). The next step is determining how long you plan on using your pool and what kind of water temperature you prefer in general. If it’s summertime, then naturally most people want their pools at around 85 degrees Fahrenheit—but keep in mind that most adults can only comfortably swim when it’s around 82 degrees Fahrenheit!

If all this sounds like too much math for your liking, no worries: there are calculators available online that will take care of everything automatically! All they’ll require is some basic information about your particular situation and then spits out exactly what size heater will work best for both heating and keeping up with larger fluctuations in ambient temperature throughout the year as well as seasonal changes between summertime heat waves versus cold winters where outdoor pools may become dangerously cold unless heated properly beforehand so as not cause damage during operation while also ensuring maximum comfort level while using one ourselves.

## Conclusion: How to heat an Intex pool?

It’s not that hard to heat an Intex pool and it can be a lot of fun. Just remember the math; you need to know how much water your pool holds, what temperature it is, and how much energy you want to put into heating it. Then go out and get the right heater for your needs!
