Heating your pool with the sun can take some time. For example, in mid-July, the pool water can be 17 degrees Celsius and within a week warm up to 24 degrees. It entirely depends on the number of sunshine hours your pool receives and the daily temperature.

Is Pool Heating Necessary?
A comfortable pool temperature is around 28 degrees Celsius. As shown in the graph above, the water temperature rarely goes above 20 degrees, which is still quite cold. The green line indicates the water temperature with the SunnyTent, which is almost always above 25 degrees and sometimes even above 30 degrees. So it is certainly wise to invest in pool heating to have up to 10 degrees warmer water.
How Much Does the Pool Cool Down?
At night, the water always cools slightly during the summer, which means your swimming water always loses 1 to 2 degrees of warmth. It doesn’t matter which heating method you use, unless you use a cover like the SunnyTent pool cover. The SunnyTent heats the water through the thermal effect of the foil and retains the heat because the pool cover is placed over the pool. This keeps heat loss to a minimum.
