Owning your personal pool is an excellent means to relax and take a bit of beneficial exercise. It is in addition great for socialising with relatives and friends. A lot of people have discovered that it is possible to significantly improve the desirability of a pool/spa and the swimming season via heating it and you are able to buy very capable pool heating equipment which makes doing this realistic. However, if a pool is warmed and is left uncovered this is like throwing money in the trash since you will be wasting a significant amount of energy.
Evaporation is the way the majority of heat is lost from a pool, this will happen to all pools but factors involving the positioning determine the extent of the issue. Evaporation is a natural process that happens permanently regardless of the temperature, however the higher the temperature the greater the rate, and therefore the warmer you heat the water the greater the loss of heat. Humidity is another issue as the more humid it is there is a lower ability for the atmosphere to take up more water vapor. Additionally wind has a key impact for the reason that it moves the moist air above the water making space for further evaporation and thereby speeds up the loss of heat.
Pool covers are available over a large price range ranging from standard manual products through to expensive motorised examples, however, the fundamental aim is the same, to act as a vapour barrier. Whilst you can try and shelter your pool/spa from the wind to decrease the impact of loss of heat this will merely reduce the heat loss and the warmer you like the water the more evaporation there will be. A pool cover keeps the heat loss in check and is a big help in keeping your heating outlay as little as possible.
It is always best to keep the pool cover in place when it is not in use. But be aware that keeping your cover on the pool will reduce the solar gain (sunlight heating the pool) however you are able to purchase covers intended to minimize this effect and this should be borne in mind while purchasing a cover for your pool.
The key point here is that you can save yourself money on the heating charges through utilizing a suitable cover for the pool. And then you will find a few extra benefits to bear in mind. By means of reducing water evaporating you also save on pool chemicals and do not have to add fresh water as often. A cover also prevents debris getting into the pool so reduces cleaning too.
