Factors to Consider When Looking for a Pool Heater- Consumer Guide

Here are the most important key factors to look for when looking for a pool heater. These factors will help you make a better decision as per your requirements and needs.

Let’s have a look at them.

Types of Pool heaters

It is important to have proper knowledge about types of pool heaters before jumping towards other factors. There are three types of pool heaters which are classified on the basis of power source. 

Choosing among them depends upon some factors like; size of your pool, pool type (in ground or above ground) and your budget. However, we will guide you which one is better for whom and when.

1. Electric pool heaters (Heat Pumps)

These pool heaters use electricity to run as the name indicates itself. These pool heaters take time to heat the pool water but the results stay longer. They can heat up large pools more efficiently and for a longer period of time.

best electric pool water heaters consumer reports

However, they are a bit expensive. Also, electric pool heaters are more efficient than the gas powered ones.

2. Gas powered

Gas powered pool heaters either use Natural gas or Propane as a fuel. Such heaters heat the pool instantly for a short period of time irrespective of the weather condition. They are not highly efficient comparative to electric heaters but are good for small pools to heat instantly.

best gas pool heaters consumer reports

In addition, the gas powered heaters are affordable but the expense of fuel makes it pricey. We would recommend Natural gas or propane pool heaters to opt for only when you use your pool occasionally. 

3. Solar pool heaters

These heaters work with the solar panels which absorb energy from the sun and transfer it to the pool. These are eco-friendly and don’t cost you on a monthly basis unlike other ones. However, the installation cost of solar panels is quite high.

Size of the pool

The type of pool heaters selection depends upon your pool size as well. If you have a small pool (above ground or in ground), it would be best to opt for gas powered or low-power solar heaters. For big pools, either opt for electric ones or high heat output (BTU) of gas powered ones. 

The simple rule of thumb is, the larger the pool size (more gallons of water) the higher heat output is needed to heat the pool water irrespective of the heater type. The BTU (heat output) is another factor which helps to select the right size of pool heater (we will be discussing it in detail in the next section below).

BTU and Size Consideration (How to measure the size)

Each and every pool heater comes with a specific amount of BTU (British Thermal Unit) which depicts the heat output of the pool heater. The amount of heat output needed to heat your pool water depends upon the size of your pool or how much your pool holds water (in gallons).

You need to run some calculations to get the correct size of pool heater with respect to heat output. First of all, you need to calculate the pool size. Here are the step by step calculations which will help you get the best pool heater size.

best pool heaters reviews
  1. First you need to know how much change you want in the temperature of your pool water. 

             Average temperature in cold season – your desired temperature = Your target   

             temperature rise ( For example; 70-60=10 degrees)

It means you need to raise your pool temperature by a 10 degree increase in Fahrenheit. 

  1. After that, calculate your pool size area in square feet (Length x width).
  2. Multiply the pool size (square feet) by Target temperature rise and by factor 12.

           Pool size x target temperature x 12 = BTU range of pool heater.

  1. You can convert the gallons of water (your pool hold) into pounds. 1 gallon = 8.83 lbs. And, further divide the pounds by 24 hours if you want to calculate per hour.

 For your information, 1BTU increases the 1 Lb of water. You can calculate it that way as well.

Compatibility

Another important factor which most of the users don’t bother to look at is the compatibility of the pool heater with your pool. For instance, if your pool contains salt water, look for the details whether it is safe to use for that or not as the pool heater might get damaged/rusted in the long run.

You can also clean your pool one time properly before installing a heater either without draining or with draining, depending upon the need.

Also, manufacturers have mentioned (mostly) about whether the pool heater is best for above ground pool or in ground pool.

However, we will guide you properly as well in detail so you wouldn’t be worrying about looking into the details from anywhere else. 

But…! 

Before that, here is a small description about how to install the pool heater (for those who don’t know), let’s dive into that first.
