5 Smart Ways to Save Money on Your Hot Water System

Most households spend a significant amount of money on energy. And a substantial proportion of that energy is used to heat water. If you want to cut your household budget or lower your energy consumption to reduce greenhouse gas emissions (or both! ), reducing the energy required to heat water is a wonderful place to start.

Let’s look at how we might reduce the energy costs associated with water heating in your Sydney home. Here are some strategies to help you save money on your water heating expense.

Water Heater Tips:

1. Lower the Thermostat

As a general rule, you want to set your water heater thermostat to 60 degrees Celsius. But you can lower that setting by as little as 5 degrees or as much as 20 degrees—depending on the temperature of the water that comes out of your tap and the temperature you feel comfortable with. You’re looking for hot water (of course), but you also want it to be comfortable to touch.

Try taking a shower after you’ve made the adjustment; it’s unlikely you will notice a substantial difference in the temperature. Not only does this small decrease cut costs, but it also reduces scalding and slows mineral buildup and corrosion in your heater and pipes.

2. Insulate the Tank

Heat loss through the side of the tank is the fastest way the temperature of the water in your water heater will drop. So insulating the tank and sealing any cracks or gaps reduces energy use by keeping that water warm.

There are two ways to insulate your tank: Install an insulated jacket that slips over the outside of your tank or have a company come and install foam or fibreglass insulation around the tank. If you choose an in-tank insulation option, ensure the insulation thickness and rating are sufficient for your tank size. The insulation is wrapped in a corrosion-resistant material.

3. Use Less Hot Water

This tip may seem counterintuitive, but consider this: Hot water uses more energy than cooler water. Therefore, you can save energy and money by reducing the amount of time that hot water is running.

It’s not the only way to save, but cutting back on hot water usage and water heating costs by a few degrees can add up.

4. Don’t Skip Hot Water System Maintenance

It is crucial to have your hot water system professionally inspected annually to ensure that it’s in good operating condition. This will help prevent expensive damage to your tank and its components.

Your plumber will conduct a thorough inspection and make any repairs necessary to ensure your hot water system is running efficiently.

5. Replace Your Water Heater

If your water heater is older than 10–12 years, consider replacing it. The cost to replace your hot water tank may seem high, but it is a proactive investment in your home.

A new water heater will save you money on energy costs, be more efficient and reliable than an older model, and reduce your total carbon footprint. For the best value and lowest cost, consider a tankless system, saving up to 40% of the energy a traditional water heater uses.


You can save money on a hot water system in many ways. You can do it by preventing damage and costly repairs, and you can do it by modifying habits and testing out some of the equipment on the market.
