Hot Water System Electrical Repairs and Efficiency Timer Installations

There’s nothing more inconvenient than turning the shower on to find out you’ve only got cold water available. If you’re in urgent need of electrical repairs to your hot water system due to it simply not heating anymore or causing the circuit to trip, get in touch with us today!

If you have rooftop solar panels and an electric hot water system installed on your property, check out our information below and contact our team to discuss how you could potentially save on your power bill through the implementation of timer-controlled hot water heating.

TIMER Benefits

Installing a hot water timer alongside a heating element size reduction can lead to noticeable savings on your electricity bill by optimising when your hot water system operates, maximising the usage of your solar PV systems generated energy.

  • How It Works:

A hot water timer installation gives you the ability to schedule the heating of water within your storage tank at set times of the day (within 15 minute increments). The timer is programmed to operate during peak solar energy production periods of each day, typically between 9am-4:30pm.

  • Maximising Solar Energy:

Installing a smaller 1.8kW heating element in coordination with the timer helps to maximise the heating of water from free, solar-generated energy instead of drawing electricity from the supply grid, further increasing your savings.

  • Ability To Sustain Hot Water Supply:

If your hot water system runs cold due to additional holiday guest usage, you can manually override the timer to reheat the water within a few hours. This is a key advantage over off-peak metered supplies, which require you to wait until the following morning for hot water to return.

common QUESTIONS

I’ve been told my hot water system is off-peak and metered seperately, what does this mean?

Appliances such as hot water systems that don’t require a constant supply of power to operate correctly can be connected to an economy tariff.

There are two economy tariff options in Queensland depending on how many hours per day you wish to run your appliance:

Tariff Available
Volume Controlled Night
Depending on your electricity retailer, this tariff may be referred by various names, including Super Economy, Night Rate, Tariff 31, Control Load 1 (CL1).		 8+ hours (around 10pm – 7am)
Volume Controlled
Depending on your electricity retailer, this tariff may be referred by various names, including Economy, Night Rate, Tariff 33, Control Load 2 (CL2).		 18+ hours (usually outside 4pm – 9pm)

How long does it take to heat a standard electric hot water system?

To heat a 250L electric hot water storage tank full of 15 degrees celsius incoming cold water to a recommended 60 degrees celsius will take the following amount of time based on the listed heating elements:

  • 1.8kW Element – 7.3 Hours.
  • 2.4kW Element –  5.5 Hours.
  • 3.6kW Element – 3.7 Hours.

For a 315L hot water storage tank increase the time taken by 25%.

For a 400L hot water storage tank increase the time taken by 60%.

What lifespan should I expect from my hot water system?

An electric hot water system typically lasts between 10-20 years, heavily dependant on factors including:

  • Water supply quality
  • UV and Weather exposure
  • Usage patterns
  • Material construction
  • Maintenance frequency
