Are You Paying More Than You Should on Power?

Energy-saving home setup designed to reduce electricity costs title: Reduce electricity bills with energy-efficient home electrical setup

With electricity prices on the rise across South Australia, it's no surprise that many households are looking for ways to cut costs. But between the online advice, energy-saving gadgets, and mixed opinions, it can be hard to separate fact from fiction.

At Mastin Electrical, we’ve worked in homes and businesses across Adelaide, and we’ve seen firsthand where energy savings can (and can’t) be made. Here's what actually works — and what doesn’t.

💡 1. Switch to LED Lighting – It's a No-Brainer

Tip: Replace old halogen or incandescent globes with LED lights.
Why: LEDs use around 80% less energy and last up to 10 times longer.

Myth Busted: “Turning lights on and off uses more power than leaving them on.”
Truth: This might’ve been true with ancient fluorescent tubes — not modern LEDs. Always turn lights off when you leave a room.

❄️ 2. Air Conditioning: Set & Forget (The Right Way)

Tip: Set your aircon to 24–25°C in summer and 18–20°C in winter. Every degree outside this range can increase your energy use by up to 10%.

Myth Busted: “Cranking the thermostat to 16°C cools the house faster.”
Truth: It doesn’t. It just forces the system to run longer and harder, using more power.

Bonus: Install a smart switch or timer to avoid running it longer than necessary. We can help you set this up.

🔥 3. Heating: Avoid the Hidden Power Guzzlers

Tip: Use zoned heating (heat only the rooms you need) and seal any draughts to keep warmth in.

Myth Busted: “Oil column heaters are the cheapest way to heat a room.”
Truth: They can be economical in small, enclosed spaces — but in larger or draughty rooms, they’re far less efficient than reverse-cycle split systems.

If you’re using plug-in heaters long-term, it might be worth upgrading to a more efficient fixed heating system.

🕰️ 4. Use Timers, Sensors & Smart Tech

Tip: Installing timers, sensors, and smart switches is one of the most cost-effective ways to curb energy use — especially for outdoor lighting, bathroom fans, and underfloor heating.

Example: Bathroom heat lamps left on all day can chew through power. With a timer or smart switch, they’ll shut off automatically.

We supply and install smart solutions to make energy savings effortless.

⚡ 5. Know What’s Pulling the Most Power

Some of the most common energy-hungry appliances we see include:

Old fridges and freezers
Electric hot water systems
Pool pumps running longer than needed
Inefficient lighting

Solution: An energy audit or power usage meter can help identify where you're losing money.
