How to maximise the value you get out of your solar hot water system

Just having a solar hot water system isn't enough - you need to make sure that you have it installed by a professional, and once it's installed you should use it efficiently.

First - make sure it's installed right

Your solar professional should pay attention to these key details.

  • Your roof's structural strength can support the weight of the system
  • The tank and solar collectors are as close together as possible (reduces the length of connecting pipes - especially important in constant pressure and pumped systems).
  • Solar collectors won't be shaded by trees or buildings
  • Install the system as close to the kitchen, bathroom and laundry as possible
  • Pipes are well insulated
  • Frost protection is included if you're in a region that needs it
  • Check your area's water quality as this can affect the systems warranty

On your side, you need to ensure that you check the warranty details, get a certificate of compliance and use a licensed professional (you'll only find licensed professionals responding to your job when you use Service Central).

Second - once it's installed, use it effectively

The best way to get the most out of your solar hot water system is to use hot water efficiently around the home.

  • Do 'hot water' jobs early in the day, as this let's new water get heated during the day.
  • Set the booster thermostat to 60 degrees celsius. The lower the thermostat setting the lower the amount of energy used to heat supplement solar heating is.
  • Use less hot water but sticking to principles to saving water (8 tips on saving water here)
  • Follow the manufacturer's recommendations for maintenance.
