By solarising your hot water, you can save money and reduce your greenhouse gas emissions. The recent publication, Go Solar and Save, produced by the Australian Greenhouse Office, states that a solar hot water system could save you between $300-$700 off your electricity bill and reduce your greenhouse gas emissions by around 2-4 tonnes of CO2 every year.*
Solarising your hot water is an easy and effective way to help the environment and save money on your energy bills.
We simply add a solar collector to your roof and replace your water tank, so your hot water is heated by the sun instead of traditional electricity or gas.
Why go solar?
Hot water heating makes up 16% of an average household’s total greenhouse gas emissions* and is the second largest source after transport. By solarising your hot water system, you’ll cut down your energy bills and do your bit to reduce greenhouse gas emissions.

Here's how it works:
- A solar collector is installed on the roof of your home
- The sun heats up the water in the solar collector which then gets added to your gas or electric hot water storage
- Instead of using energy to heat up cold water, you're using much less energy to produce water that’s actually already warm or even hot
- Your solarised hot water system is ready to enjoy, with no change to your water supply

It's simple to solarise your hot water with Hearns Heating and Cooling systems. We can offer you a fully installed system that's right for you - we'll even arrange applicable Government rebates.
