Perth, West Australia is fortunate to get hot, sunny days for much of the year. However, this doesn’t mean that swimming pool heaters are redundant in this part of the country. In autumn, or from March to May, temperatures can drop to as low as 21 °C, below a swimming pool’s comfort levels of 24 to 28°C; and in winter, temperatures fall to an average of 17 to 18 degrees Celsius.
With these in mind, people who wish to extend their “swimming season” need only to install heaters in their pools and spas. At present, they can choose between two types of heaters: solar and gas. Gas-fired heaters work faster, but they’re costlier to operate. Solar heaters, on the other hand, are more cost-effective, but they require a more powerful pool pump to work properly. In addition, spas require more powerful heaters since their comfort levels rest somewhere between 34 to 38 °C.
Despite the availability of such options, people should be careful not to heat their pools too much, because warm bodies of water are a suitable environment for algae to thrive. Increased algae growth, in turn, leads to more frequent pool cleaning, which can get very expensive over time.
