Heated Pool can be awesome.
Establishments that offer pools for twelve months of the year, yet travellers only use them for seven – by slightly heating up the water travellers can almost swim all year round.
By warming up the water by five to 10 degrees, the swimming time will be stretched by a number of weeks or even months on either side of summer.
There are a number of different ways to warm pool water, with the solar version thought to be the most cost effective in the long run.
The warmer pool water also allows travellers to swim later into the night.
