Hot Water Timer Installation Services Brisbane
Your electric hot water system is likely one of the largest electricity consumers in your home — typically accounting for 20–30% of your household energy bill. Most hot water systems, by default, heat water whenever the thermostat calls for it — including during expensive peak tariff periods. A simple timer controller changes this entirely.
By programming your hot water system to heat only during off-peak hours — or, for solar households, only during the middle of the day when your solar panels are generating — you can dramatically reduce the cost of heating water without any change to your hot water availability.
Fused Air installs hot water timers and smart controllers for electric storage hot water systems across Brisbane and Moreton Bay. It’s one of the most cost-effective electrical upgrades we carry out — many customers see payback within 6–12 months on the cost of installation.

Hot Water Timers
Hot Water Timers and Smart Controllers
- Standard 24-Hour Timer Switch
A 24-hour mechanical or digital timer installed in the hot water circuit allows you to set the heating window — for example, 10am to 3pm to align with solar generation, or 10pm to 6am to use off-peak tariff rates. Simple, reliable, and inexpensive.
- Smart Hot Water Controllers
Smart controllers go further — they can monitor your solar inverter output in real time and activate the hot water system only when excess solar is being generated. Some models (such as the Catch Power or Solaray Controller) integrate directly with your solar system for automatic optimisation.
- Tariff 31/33 Off-Peak Relay Setup
If your hot water system is eligible for Queensland’s off-peak tariffs (Tariff 31 or 33), we can wire the system with the appropriate relay and register it with your electricity retailer. Off-peak tariffs charge a lower rate for electricity used during specific overnight windows — significantly reducing hot water running costs.
How Much Can a Hot Water Timer Save You?
- Average household hot water cost on standard tariff: $600–$1,000 per year
- Hot water cost using off-peak tariff (Tariff 31): $200–$400 per year
- Hot water cost using solar hours timer: $50–$150 per year (solar generation absorbed)
- Typical timer installation cost: $200–$450
- Typical payback period: 3–12 months
The exact savings depend on your current electricity tariff, your solar system size (if applicable), and your household hot water usage. We’ll give you an honest assessment of likely savings at the time of your free quote.

Frequently Asked Questions
Will I run out of hot water if I use a timer?
For solar households, a smart controller is significantly more effective than a fixed timer. Solar generation varies day to day, and a smart controller automatically responds to your actual generation — a fixed timer doesn't. The additional cost of a smart controller is typically recovered in 1–2 years through better solar utilisation.
If your system is already on an off-peak tariff and it's correctly wired, a separate timer may not be necessary. However, if you also have solar and want to shift heating to midday solar hours, a timer or smart controller adds additional savings on top of the off-peak rate.
Yes — installing a timer in the hot water circuit involves working with your switchboard or the dedicated hot water circuit, which is licensed electrical work in Queensland.
