There is a lot to investigate if you want to save money by solar heating your pool, but it is definitely worth exploring as an option. In many cases, using a solar pool heater is significantly more cost efficient when competing against conventional heating methods such as gas or pump driving heaters.
Solar Heaters
There are a number of components which are typically included with a pool heating system, including:
Solar collector – This is a device which uses circulation to heat water in your pool.
Filter – To maximize the efficiency of the system, the filter collects dirt before it goes through the collector.
Pump – The pump ensures that water is directed through the filter and collector for heating.
Flow control – This is a valve which can have automatic or manual features to direct water through the solar collector.
Heating Process
In order to heat the water, the pump will direct water through the filter and then your solar collector. You can use a system with more than one solar collector, depending on your needs. All water that passes through the solar collector is heated and then circulated back into the pool.
If you want to get really high-tech, there are also solar heating systems which have sensors that control the circulation process. There is no risk of the water getting too warm as a bypass is built in for when the pool is already sufficiently heated.
Pool Collector Materials
Unglazed collectors are a good choice if you live in South Australia as they work well in any temperature above freezing. As these pool collectors are made from materials such as rubber or plastic and don’t have glass they are fairly inexpensive. If you do go for glazed collectors, which are typically made from copper tubing and an aluminium plate covered by tempered glass, you will pay more for the system.
Choosing a Solar Heating System
There are a few conditions to consider when installing a solar heating system as they are not one-size-fits-all. You will need to determine the site of the pool’s solar resource. That will allow you to then begin the task of determining the system size for your needs. It is also important to think about the system efficiency, which requires correct orientation and tilt for optimum collection.
Professional Contractor
While it is entirely possible to install a solar heating system for your pool without the help of a contractor, it is not advisable unless you are sure you know what you are doing. The measurements involved in orientation and tilt alone will make all the difference in the efficiency of the system. There are also cost calculations for the materials you will need, which are or should be largely based on the source and location data collected from measurements.
If you do want to err on the side of caution by hiring a contractor, make sure that you check the individual or company’s credentials. A reliable contractor who has installed solar heating systems in your area is likely the safest bet. However, check reviews and pricing for a number of contractors for the best price and quality of workmanship.
