How To Use electric boosted solar hot water

​Electric boosted solar hot water has two power sources.


The primary source is the heat from the Sun collected in the panels, which is free energy.

The back up power source is an electricity (called a booster) which we pay for.

Using solar hot water as designed means leaving the back up booster off until required, therefore using the Sun as the primary power source.

Only on days when not enough heat from the Sun is available (extended cloudy periods and Winter) is electricity meant to be used.

The “backup” sources of power or “Boost” is only to be used when there is insufficient heat available from the Sun to fully heat the water. This will occur during colder months and/or extended cloudy periods.

On average in Brisbane QLD, for approximately 7-8 months of the year, a Solar Hot Water system will provide most homes with “free” hot water.

During the rest of the year, a correctly designed and installed Solar Hot Water system will preheat the water before requiring the use of backup power, dramatically reducing the boost required, therefore lowering energy bills.


In Brisbane, on a clear Winter 16°C day, the amount of energy required to "boost" is about one-third of what would be consumed with a standalone electric or gas hot water system in most homes.

We recommend setting your booster to an automated service. Then you will always have hot water regardless of what the weather is doing while maximising savings potential of your hot water bill. 


This is what Solar Hot Water was designed to do. 

If you currently have Solar Hot Water and do not get these results, then the system has been incorrectly installed or has stopped working properly, guaranteed!
