SOLAR HOT WATER SYSTEMS - SYDNEY

Solar Hot Water Systems

A solar hot water system is made up of two main components. The storage tank to hold the hot water and the solar panels or evacuated tubes, known as collectors to attract the sun's heat energy. Panels are usually flat while the evacuated tubes will be circular. Evacuated tubes are more efficient and cost a little more as a result. Solar hot water systems are available in 2 main forms, thermosiphon or Split/Pumped.

Thermosiphon solar hot water system

This method of solar heating houses the collectors and the hot water tank together on top of the roof.  A thermosiphon system relies on natural convection called thermo-siphoning. As the sun shines down and heats the collectors, the water warms and in turn travels up into the storage tank, pushing the cold water out and down to the collectors to be warmed. This cycle continues and is relatively passive... quite energy efficient when it comes to a water heating service.

Split/pump solar hot water systems

A split/pump system will have a separation between the hot water storage tank and the collectors. The collectors will be housed in the most desirable location, usually a north-facing rooftop location. If this is not possible and efficiency is comprised, extra panels may be required to achieve the desired amount of solar power to warm your hot water. Our solar hot water specialist will be able to calculate the number of collectors you'll need, based on your hot water needs and the household the unit will service.

With the separation of the hot water storage tank and the collectors, a pump is required in order for the water to travel up to the solar collectors to be warmed. This type of hot water unit will have a sensor device to monitor the temperature. When the water in the collectors reaches the desired temperature, it will travel down to the water tank and in turn, the cooler water from the tank will be pumped up to the collectors to be heated.

Both these systems have relatively the same amount of energy use. A factor that may play into your selection process could be the structural strength of your existing roof. As a thermosiphon water heating service is installed on the roof with the water tank and the solar collectors, this can be quite heavy. Yet, a split/pump system will require a little more energy when pumping the water instead of relying on the thermo-siphoning factor.

Boosters For Solar Hot Water Systems

It is a wise decision to opt for a booster to compliment your hot water system when installing a new solar hot water system. As we all know too often, weather can be unpredictable. If there is little sunshine, you'll see minimal energy created... meaning there will be minimal hot water for you and your household.

It is not unusual for solar hot water systems to have a backup energy source. The backup energy source will either be an electric or gas. This backup energy source will kick into gear when the temperature sensors trigger that the water tank temperature has dropped below a certain amount. A hot water tank temperature should not fall below 60 degrees by Australian Standards. Ensuring your water heating supply remains above 60 degrees is important and reduces your risk of legionnaires disease.

Well-equipped solar hot water systems will have a booster, whether your chosen hot water system is a thermosiphon one or a split system. Taking extra precautions to ensure you are never without hot water is always a wise choice. Our local plumbers can advise on the best solutions for boosters and explain how a booster helps to support your solar hot water system.
