One efficient way of reducing pool heating costs is to cover your swimming pool when not in use. One can easily see that swimming pool heating costs using a hidden pool covers Sydney is much lower than those with pools without covers.
There are several ways in getting your latest model of swimming pool covers. Hidden pool covers is one alternative in saving energy costs. Hidden pool covers Sydney are an automatic pool cover that is seen when in use and hidden when not in use.
How it works
Swimming pools lose energy in a variety of ways by its nature. Evaporation is by far the largest source of energy loss. Evaporating water needs big amounts of energy.
In technical terms, it takes 1 BTU (British thermal unit) to raise one pound of water. However, each pound of 80 degrees Fahrenheit of water that evaporates takes a whopping 1,048 BTU of heat out of the pool.
The rate of evaporation on an outdoor pool varies. This depends on the pool’s temperature, air temperature and humidity, and the wind speed at the pool’s surface. The higher the pool temperature and wind speed and the lower the humidity, the greater the evaporation rate.
Pool types
In areas that are windy, add a windbreak—trees, shrubs, or a fence—to reduce evaporation on your pool. The windbreak needs to be high and close enough to the pool that it doesn’t create turbulence over the pool (increasing evaporation).
Indoor pools require room ventilation to control indoor humidity caused by the large amount of evaporation. However, they are free from the changes in the environment.
However, they can still lose a lot of energy from evaporation. The ventilated air also must be conditioned, which adds to the energy costs.
Covers
From both outdoor and indoor pool, pool covers minimize the evaporation. It is also very effective when pools are covered when not in use. It can reduce up to 70% savings.
The pool covers on indoor pools not only can reduce evaporation but can also work on the need to ventilate indoor air and replace it with unconditioned outdoor air. Shutting exhaust fans can also save more energy.
Types
Basically, a large plastic sheet is all that is needed for a pool cover. Those plastic sheets from stores are not really the most ideal. These sheets must meet the requirements of being a vapor barrier.
First, it is difficult to handle and store and it tears easily, while sunlight can deteriorate it fast enough. At most, it can only last about 1 or 2 seasons.
Special materials
Covers for pools need those that are designed for swimming pools, are made of special materials like the TV-stabilized polyethylene, polypropylene or vinyl. They can be transparent or opaque, light or dark colored.
Hidden pool covers Sydney are usually those that are automatic or semi-automatic. It has mounted reels that covers (or uncovers) the pool at a push of a button.
They are actually hidden from view when the pool is used. The semi-automatic covers also use a motor-driven reel system.
