Determining the right size for your hot water tank, specifically an electric storage hot water system, primarily depends on the number of people living in your household and their hot water usage habits.
To ensure you have enough hot water for daily needs without running out, consult guides based on typical usage patterns. According to Pure Plumbing Professionals, the recommended sizes for electric storage hot water systems are as follows:
| Household size | Electric storage hot water system size |
|---|---|
| 1 person | 25 litre |
| 1 - 2 people | 50 litre |
| 2 - 3 people | 80 litre |
| 3 - 5 people | 125 litre |

Why Size Matters
Choosing the correct size is crucial for both convenience and efficiency:
- Too small: You might frequently run out of hot water, especially during peak usage times (like morning showers).
- Too large: The tank will heat more water than you typically use, leading to wasted energy and higher electricity bills.
Consider your household's specific needs. If you have multiple people showering at the same time, frequently use appliances like dishwashers or washing machines that require hot water, or have a large bathtub, you might consider leaning towards the higher end of the recommended range or consulting a professional.
Ultimately, selecting the appropriate tank size ensures a consistent and efficient supply of hot water tailored to your home's demands.
