Tired of high energy bills? Your old hot water system might be part of the problem.
Hot water typically makes up 25–30% of the average Australian household energy use — so switching to a modern, energy-efficient water heater can make a real difference to your monthly bills.
In this blog, we’ll show you how upgrading your system can help you save money, use less energy, and enjoy hot water when you need it.
1. Old Systems Use More Power Than You Think
If your hot water system is more than 8–10 years old, it’s probably using more energy than it should. Older models weren’t built with today’s efficiency standards, and over time, they also become less effective due to wear and tear or sediment buildup.
Result?
Longer heating times = higher electricity or gas bills.
2. Choose the Right Type of Modern System
Today’s water heaters come in a range of energy-efficient models:
- Heat Pump Water Heaters – Use ambient air to heat water, cutting electricity use by up to 60%
- Solar Hot Water Systems – Use solar panels to heat water during the day, with gas/electric backup
- Instantaneous (Tankless) Units – Only heat water when you need it, no standby loss
- High-efficiency Gas or Electric Storage Systems – Use insulation and smart controls to reduce energy waste
The key is choosing a system that suits your home size and usage patterns.
3. Off-Peak Tariffs Can Save You Even More
If you choose an electric storage system, ask your provider about off-peak electricity plans. These heat your water overnight when rates are lower — great for families that mostly use hot water in the morning or evening.
Housecare Plumbing can help you check if your switchboard supports this option.
4. Regular Servicing Keeps Your Bills Lower
Even the best system will use more power if it’s not maintained.
We recommend:
- Flushing the tank every 1–2 years
- Checking for leaks or rust
- Testing the pressure relief valve
- Inspecting the thermostat and heating element
A quick check-up once a year can keep your system running smoothly and efficiently — and stop small issues from becoming expensive repairs.
5. Upgrade Once — Save for Years
Yes, a modern system might cost more upfront. But most homeowners see real savings on their energy bills within the first 12–24 months.
Plus, newer systems are:
- Quieter
- Safer
- More compact
- Less likely to break down unexpectedly
And many models come with 5–10 year warranties for extra peace of mind.
