As energy prices continue to rise and concerns about climate change grow, more and more households in Australia are looking for ways to reduce their energy consumption and greenhouse gas emissions.
One important area to focus on is your hot water system, which can account for a significant portion of your household’s energy use.
In this article, we’ll explore the different types of hot water systems available, the energy efficiency features to look for, and how renewable energy systems like solar PV can significantly reduce your energy bill and contribute to a more sustainable way of life.
We’ll also provide tips on upgrading hot water systems for greater energy efficiency, helping Australian households become energy efficient homes, save money, and reduce their environmental impact.
Types of energy efficient hot water system
There are a few types of hot water systems available, each with its own advantages and disadvantages in terms of energy efficiency, cost, and installation requirements.
Let’s explore the three main types of hot water systems: electric, gas, and solar-powered.
- Common and easy to install, but can be more expensive to run than other types
- Choose models with high energy efficiency ratings and features like timers and temperature control to reduce energy use
- Heat pump systems, which extract heat from the air to heat water, can be a more energy efficient option
- Can be more energy efficient than electric systems, but require access to a natural gas supply
- Choose models with high energy efficiency ratings and ensure proper maintenance for optimal efficiency
- Natural gas is a relatively clean-burning fuel, making it a good option for households concerned about greenhouse gas emissions
- Highly energy efficient and can significantly reduce energy bills over time
- Uses solar panels to heat water, making them a renewable energy option
- Require good exposure to sunlight, making them more suitable for the typical Australian local climate
- Choose models with high energy efficient ratings and consider installing a booster for times of low sunlight or high hot water demand
Energy efficient features for hot water systems
When choosing a hot water system for energy performance and efficiency, there are several features to look for.
Energy efficiency rating: Check the energy efficiency rating of the system. The higher the rating, the more energy efficient the system is. It’s worth looking into the minimum energy efficiency standards for your system of choice. A higher rating can result in less energy consumption, greenhouse gas emissions, and lower energy costs.
Energy efficiency upgrades: Look for models with built-in timers and temperature control, which can help to reduce energy use by ensuring the system only heats water when it’s needed and at the right temperature.
Heat pumps: Consider heat pump systems, which extract heat from the air to heat water, as they can be a more energy efficient option for electric hot water systems. This is because they use existing heat, as opposed to electricity, to heat the water, resulting in reduced consumption and costs.
System size: Consider the size of the system, as a larger system may use more energy than necessary for your household’s needs. By reducing energy consumption, you can reduce your carbon footprint, contributing to a more sustainable future while potentially saving energy and money on your bills.
By choosing a hot water system with these energy efficiency upgrades and features, you can reduce your energy consumption and lower your energy costs.
Solar PV: Renewable energy systems for saving on energy bills
Renewable energy systems are becoming increasingly popular as households look for ways to reduce their energy use and bills. One of the most promising options for heating water is solar energy.
What are solar-powered hot water systems?
Solar panels and solar PV systems can be used in residential buildings to heat water in a highly efficient and cost-effective way.
One of the key benefits of solar hot water systems is that they rely on a free and abundant source of energy – sunlight.
By harnessing this energy, households can reduce their reliance on grid-supplied electricity or gas and potentially save money in the long run when it comes to running costs.
What’s more, solar hot water heating produces no greenhouse gas emissions during operation, making them a highly sustainable option.
Will they suit my household?
The availability and suitability vary depending on the local climate and household size. For example, households in sunny areas like Queensland or Western Australia may benefit more from solar hot water heating than those in cooler or more overcast areas.
However, with advances in technology, solar hot water systems are becoming more efficient and effective in a wider range of climates.
Additionally, some regions offer rebates or incentives for households installing renewable energy heating and cooling systems, further encouraging the uptake of solar hot water systems.
Energy efficiency upgrades for hot water systems
Upgrading existing hot water systems is a great way to improve energy efficiency and save money on your energy bills.
Let’s explore some tips for households looking to upgrade their hot water systems:
- Insulate hot water pipes to reduce heat loss and improve efficiency
- Install a water-efficient showerhead to reduce the amount of hot water needed for showers, saving both water and energy.
- Regularly maintain and service hot water systems to ensure that they’re running efficiently and not wasting energy.
- Consider installing a booster for solar hot water systems, which can provide additional heating during times of low sunlight or high hot water demand.
- Think about upgrading to a more energy efficient system with a higher energy rating, such as a heat pump or solar power system.
- Check with your energy provider or local government for rebates or incentives available for upgrading to a more energy-efficient system.
Final thoughts & next steps: energy efficient hot water systems for your home
Home energy efficiency is crucial for reducing energy bills and greenhouse gas emissions, and hot water systems play a significant role in achieving these goals.
Upgrading hot water systems with energy-efficient features or installing renewable energy systems can significantly reduce energy consumption and potentially save you money on your bills.
