What is a Solar Collector?
The most cost efficient and accepted method of solar heating a pool is by using kilometres of small diameter synthetic plastic tubing separated by a heat absorbing web as a collector.
-
How is Solar Pool Heating Installed?
Existing Pools:
The most widely accepted installation method is to pump filtered water through the collector and back to the pool. The existing pump may be used or a boost pump incorporated to reduce the load on the existing filter pump.New Pools: The installation is the same as existing pools except it is recommended that separate flow and return lines are installed when the pool is being built.

How does Solar Pool Heating work?
The strip absorbs radiation from the sun and also picks up heat from the roof. In order to pick up heat from the roof, the collector can be spread with spaces between each strip of collector. In this instance a dark roof is better than a light roof. When sizing a system however, a fully balanced solar collector with the correct m² as per Australian Standard is more effective than spreading out on a dark roof.
-
Do some systems perform better than others?
Yes! The Sunbather strip absorber provides a square metre of performance for every square metre of absorber. Tubular collectors are calculated on the width of the tube only. Sunbather has been tested under Australian Standard AS2535. All collectors have items such as collector wall thickness, re-radiation, reflection and collector wetted area, and these though relevant, are far less important than the actual area of collector.
AS2535 testing allows the system to be firmly balanced because we know what we have to achieve.
-
Can the same collector area perform differently?
Yes! A system that is poorly balanced (poor flow ie too slow, or over pressured ie too fast) will perform considerably less efficiently. Our system is tested to commercial standards.
-
Why is the Design System so important?
If the design or installation is incorrect, the system wont work to full capacity
