Pool Heating Systems .... Extend your swim
Especially in the current economic climate we won't pretend to advise that purchasing and running a pool heater is cheap, however, whilst some class it as a luxury, the practicality of them, is that if you love using your pool then it makes sense to lengthen the use of them, enabling you to swim and enjoy for the whole year.
Another benefit is that it could increase your villas rental potential by extending the season than just over summer.
If you have solar panels then this is a cheaper way to run them.
