Choose a hot water system suitable for your household
Don’t wait until your hot water system dies, plan your next purchase now!
Water heating accounts for 25% of your household’s energy use – and it could be even more. It’s worth reviewing your hot water usage well before your system dies and checking out the alternatives. You may find a hot water system that saves you energy and money as well as being kinder to the environment.
Also, a new electric storage system may not be an option for your home because of new regulations aimed at reducing energy consumption.
Which hot water system is best for me?
One person uses on average about 50L of hot water a day. You will use more hot water if you use your dishwasher often, take very long hot showers or often wash clothes in warm or hot water.
Your Know Hot Water Specialist can analyse your home and usage and recommend the best hot water systems for you.
To determine the right size of system, we will need to know:
- How many people live in your home?
- How much hot water you use, and when you use it?
- When do you all shower – in the morning or evening?
- How do you wash clothes – in hot or cold water?
For most households, a solar HWS can be the most efficient and cheapest to run. If that’s not an option, here are other suggestions:
- Small household (1-2 people): Instantaneous hot water system (gas or electric) or small gas storage hot water system.
- Medium household (3-4): Gas hot water system (instantaneous or storage).
- Large household (5+): Multiple instantaneous hot water systems may be an option but gas storage units may be more economical.
Energy Star rating
Gas hot water systems have energy efficiency star rating labels; the more stars, the more efficient the water heater. The highest rating is six stars. Minimum Energy Performance Standards (MEPS) currently apply for electric hot water storage systems.
