Warwick’s Story

We have recently renovated our home. In the process we have replaced all windows with double glazing, insulated all walls and ceilings, ensured no draught gaps exist around windows and doors, replaced gas hot water with an electric storage system, replaced gas cooktop with induction cooking and replaced gas heating with reverse cycle air-conditioning. We topped this off with a 6.6kw solar system and added a timer to ensure our hot water is heating during peak solar generation times. We have also switched to Diamond Energy, so any electricity we can’t generate to meet our needs is completely CO2 free.

Our motivation for making these changes is that we wanted to save money in the long term, but most importantly, we wanted to reduce our carbon footprint.

The decision to upgrade our home has been great. Our home is cosy in winter and cool in summer. We rarely use the aircon to cool the home as the insulation and double glazing do a great job. I absolutely love cooking on my induction cooktop – it is so fast to heat and no energy is wasted as the heat goes straight into the pan and doesn’t heat the surrounding air. Since removing our gas heater, our winter air is much better quality. 

Our summer bills are down to about $30 per month which is one third the cost of our combined gas and electricity bills in our old house which was about half the size. We are generating no emissions from household energy requirements, except for our vehicle emissions which, for $145 per year, we are able to purchase carbon offset based on our annual vehicle usage.  We have an electric storage hot water system, but simply using a timer to ensure we use electricity generated by the sun whenever possible to heat our water which is saving us $360 per year on our hot water.  We also have a Powerpal which we use to monitor when it is best to throw on a load of washing, turn on the dishwasher, or pop the oven on to bake a loaf of sourdough.  

We plan to purchase an EV in 2024 and along with this we will boost our solar capacity by 3 or 4 KW.  We also hope to be able to use our EV battery to power our home in the evening utilising bi-directional charging. 

We used local electricians for appliance installation and were happy with this. We actually used one of the big national solar companies to install the solar which proved to be a total nightmare.  We may have saved a few dollars but lost out with service and fault rectification.  I would definitely recommend a trusted local installer for anyone considering solar.
