While the size of the hot water system will more than likely vary depending on your specific needs, the average 4-person Australian home will need at least a 160 litre tank for a continuous electric system, or a 250-315 litre off-peak system. If you’re in the market for a gas tank, a 4-person house averages a 170 litre tank. 270-315 litre tank should be sufficient for heat-pump users.

Handy Hints and Helpful Guides
What size hot water system do I need?
Why is the right size system so important?
If your hot water heater is too small for your needs, you will find yourself continually run out of water. On the other hand, if your hot water system is too large for your needs, you are going to spend an unnecessary amount of energy (and therefore money) heating it. This is because your hot water system will keep maintaining the heat of your water, even when you are not using it.
Can I install this system myself?
You will need a licensed plumber to install this system.
What additional parts do I need for my new system?
