Everyone desires to have a nice swimming pool in their backyard. The reason is simple- it is a perfect way of cooling off on hot days. But owning a swimming pool is not that easy. You have to make the right technical decisions while building a pool. And here is one overlooked decision homeowners make when they buy a pool heater.
Choosing the wrong size heater can lead to disappointment and unnecessary expenses. That's why tools like the pool heater calculator help you buy the right heater. So, let’s understand how a calculator saves you time and money.
Why Pool Heating Matters in Australia
Australia experiences a tropical climate which ranges from the humid Queensland, through the cool southern states of Victoria and Tasmania. Australians experience both cold and warm seasons throughout the year.
That is why a pool heater adds more time to your swimming season and makes it pleasant to dip, even when the weather outside is uncomfortable for swimming. But apart from comfort, there are financial and environmental aspects involved as well.
A small heater runs constantly and may not achieve the desired water temperature, while a large heater can waste both energy and money. Just there, the proper sizing is essential. A pool heater calculator can help you make sure that the heating capacity is appropriate enough to match your pool volume and conditions.
How to Use a Pool Heater Size Calculator Correctly
So, how do you actually use a pool heater size calculator? Here’s a step-by-step guide:
1.Measure your pool’s volume – Calculate using:
Length × Width × Average depth
For irregular shapes, break the pool into sections and add them together.
-
Input your location – Many calculators factor in regional climate data.
-
Select your desired water temperature – For example, 27–28°C is a common comfortable range.
-
Consider your swimming season – Will you heat year-round or only in cooler months?
-
Account for pool covers – A cover significantly reduces heat loss, so calculators may recommend a smaller heater if you use one regularly.
Example:
-
A 40,000-litre pool in Sydney aiming for 28°C may require a 12 kW heater.
-
A similar-sized pool in Melbourne might need 15 kW due to cooler conditions.
Without a pool heater calculator, many homeowners would underestimate this difference, leading to inefficient heating.
Other Factors That Influence Heater Performance
While the calculator gives a precise starting point, there are additional factors to consider:
1. Pool Covers
A thermal pool cover can reduce evaporation and heat loss by up to 70%. This means your heater won’t have to work as hard, lowering energy bills.
2. Wind Exposure and Shading
Pools in open, windy backyards lose heat faster. Likewise, shaded pools may need stronger heaters to maintain consistent warmth.
3. Frequency of Use
If you swim daily, you'll want a heater that can maintain a consistent temperature. For occasional use, a smaller heater may suffice since you only need to heat the pool on demand.
4. Energy Source
Different heater types perform differently depending on your setup. A pool heater size calculator helps determine capacity, but energy source choice also matters.
Choosing the Right Pool Heater
After finding the right size pool heater with the help of the pool heater calculator, you can proceed to the type of heater. There are mainly two most popular options, which are as follows:
Electric Heat Pumps
-
It consumes less energy, is compatible, and reduces long-term operating costs.
Solar Pool Heaters
-
Environmentally friendly, low operating costs, suitable in sunny weather.
A pool heater size calculator can tell you how much capacity to get, though it is important to know the advantages of each system so that you can make the best decision.
