What to Look For in a Pool Heater

A pool heater is an important investment for your entire family. There are many factors to consider when purchasing the right pool heater.

You should keep in mind the size of your swimming pool, whether you want natural or propane gas, and also the features that make the most sense for you. Weaving through all these considerations can be tricky but with our guide, it will be easier for you to navigate what will work best for your needs!

There are multiple options on the market when it comes to pool heaters so we hope this article has helped simplify things and given you some insight into which ones would suit your home and budget.

Size of your Swimming Pool

The size of your pool is the first thing to consider when looking for a pool heater. It will determine what kind of model you need, whether it will be natural gas or propane, and how efficient it needs to be.

The larger your pool, the more intense the heat needs to be – this is because water loses heat faster than other media (such as air). If you have an above-ground pool then you can purchase smaller propane or natural gas heater however if you have an in-ground swimming pool it’s likely that you’ll need to invest in a high-quality unit to keep it heated efficiently.

BTU Output

The BTU output refers to the amount of heat your heater outputs. Higher BTU pool heaters can produce more heat and therefore work faster at heating your pool water. If you have a larger swimming pool you will likely need multiple smaller units rather than one large unit which is logical when it comes to calculating the BTU you need for your pool size.

Natural Gas vs Propane Gas Pool Heaters

There are two types of gas used for these kinds of pool heaters, namely propane or natural gas. Natural gas is usually cheaper but because propane is denser it can provide higher combustion rates so if this is an important factor when looking for your next unit then propane be better suited for you.

Solar vs. Gas Pool Heaters

Solar pool heaters are a great choice for those looking to save money and live a more eco-friendly lifestyle. There is usually an installation cost however they can be very effective in heating your pool water.

In comparison, gas pool heaters have the benefit of being able to heat your pool quickly as well as having adjustable temperature controls so if you’re looking for something that goes above and beyond then natural gas might be what works best for you!

Features of a Good Quality Pool Heater

If you’re looking for a high-quality pool heater then some features will typically come as standard:

• Is the unit fully automatic? If so, does it turn on and off with your swimming pool’s filtration system? This is an incredibly convenient feature to have as it ensures that you never forget to switch your heater on or off. You can set the temperature and leave it knowing that once your pool reaches this level the heater will automatically kick in!

• A digital display showing the operational status, water level, and service diagnostics is also very useful as it gives you everything at a glance without having to go into the unit itself.

• Some models come with timers which means you can program them to turn on and off at certain times during the day. This is particularly helpful if you want your pool water to reach a particular temperature overnight or first thing in the morning.

These are just some of the features that are commonly found on high-quality pool heaters so if these are important aspects for you then you might want to consider making them priority factors when looking into your next purchase!

Frequently Asked Questions

How long does it take to heat an average-sized pool? 

The time it takes to heat your pool water will depend on the size of your pool and the unit itself. For example, if you have an in-ground pool with a surface area of 400 square meters then you could expect to wait anywhere between 8 -12 hours for the water temperature to reach 30 degrees Celsius (if using propane gas).

How much does it cost to heat a pool?

The costs will keep rising along with the size of your swimming pool. If you’re looking for an average estimate then start by calculating 0.5 cents per liter of water heated up which is around $1,200 per month if heating a 20,000-liter pool! Prevention is better than a cure, so if you’re constantly fighting with your heating unit because it constantly breaks down then you should consider investing in a high-quality pool heater rather than buying a new one every other year. 

How long can you expect a pool heater to last? 

If you’re looking for a very long-term solution when it comes to heating your pool then the best choice is a gas heater which can last between 8 – 10 years. In comparison, solar heaters will usually have a lifespan of around 5-7 years while heat pumps only have an average life expectancy of 3 -5 years. 

How do you best maintain a pool heater? 

A common mistake made when looking after a pool heater is forgetting to change your filter element at least once a year. This is incredibly important as it ensures that your unit can function at peak performance and maintain its energy-efficiency levels over the years.

There you have it; all of their most frequently asked questions answered! So if you’re considering making a purchase then hopefully this article has given you some helpful pointers that will help you out in the long run. Remember, always do your research before spending money on something that could end up being an expensive mistake!
