Solar pool heating
June 20, 2009
Solar pool heating is one of the many applications of solar based heating. These are not only cost efficient but also helps in reducing green house emissions The system is simple to use and relatively very less expensive. It allows people with this system installed to extend the amount of time in the year that they can swim, thus swimming season is expanded.
The pool itself is the storage place for the system and the pump that is usually used for filtering the water also circulates water through this solar heating system. A collector is the most important part of these systems. A typical collector is a set of plastic panels which have large headers on its top and its bottom, this collector is strapped to the roof at both ends. So during the day when the filter works, the water is first sent through the solar collectors before they are returned back to the pool area. These systems are usually efficient enough to heat large amounts of water every day and then returns the water to the pool, after increasing the temperature by two to five degree Fahrenheit.
More than seventy percent of the heat generated by the pool is lost due to evaporation, and installing such solar pool heaters which includes a pool cover is the most economical step to take to control the temperature of the swimming pool. These covers are also helpful in keeping the pool clean and maintains the usage of chemicals.
It is basically the most effective method to reduce loss of heat, evaporation of water and use of chemicals. The amount of collector area required is from fifty to hundred percentage of the pool. This depends on the user’s requirements and also the site and the collector efficiency. The best method of using the solar collector is by tilting it to the south to a degree of twenty to thirty two. Indoor pools which are going to be used the whole year would require glazed and flat collectors, which should ideally be tilted to an angle of thirty five to forty degree. Roof types and pipes could cause interference for these collectors. In such cases these collectors can be mounted on the ground on a frame next to the pool.
Most of these pool collectors must be drained fully when it is not in use as freezing conditions can cause damage to these collectors. All plumbing which is connected to it must be drained back when the pool isn’t in function.
An average system can cost an interested party from anything between $2000 to $4000, depending on the area of the collector and also the installation charges.
