I live in a large home with 5+ people, is a HWHP suitable?

You will need to ensure you get the correct size tank to benefit with 5+ people. To find the perfect balance between lower electricity bills and your family’s need for hot water, follow these steps: 
1. Count the number of people in your household and consider the people who might join or leave your household soon. 
2. Assume that each person will use around 50 litres of hot water per day. (Modify if someone prefers cold showers or very long, very hot ones). 
3. Require that your hot water tank keeps 1.5 days’ capacity at all times. 
4. Thus, multiply the number of people by 75. 

Choose a brand with the highest recovery rate. 
The HWHP comes with a timer so you can set to turn on for the whole day if required (providing it is not on a dedicated off-peak meter).
