Did you know how much your hot water is costing you? Or what you can save if you upgraded your water heating system and/ or altered tariff.
To know the exact figures or calculate your hot water cost, you can use Endeavour Energy’s online calculator.
Overall cost to own & operate the water heating system
The cost involved in running hot water system includes the cost of the hot water system, installation cost, operating costs (i.e. fuel or energy used and what it costs) and maintenance cost. You may want to purchase the most resourceful heater available on the market. But if the installation costs for getting the heater installed and making it functional are going to be pricier than it may not be cost-effective; for instance, if you buy a solar water heating system with a payback period of 15 years or more.
Consider retrofitting costs when switching between water heating system types
Well, you know the efficiency of a gas continuous-flow is superior to a gas storage tank. Nevertheless, it’s important to evaluate the retrofitting costs when making a switch from a gas storage hot water system to gas continuous flow. In some instances, it can blow out.
Location
Next, factor in the location, which is significant:
- Is it possible to wheel it around on a trolley and effortlessly be placed into the position?
- Does the hot water system require being elevated over air conditioners to be set in place?
All different alternatives of a water heater’s location should take into account the house layout. The heater’s location requires averting probable “dead legs” – that means the cold water being wasted down the drain when waiting for the hot water to emerge. The ideal position of the hot water system is to place it as near to the kitchen as is possible, as this is the tap that often gets turned on in the house.
Major Types Of Hot Water Systems In Australia. Which One Is Best?
Types of hot water systems include electric and gas storage, continuous-flow, heat pump and solar-powered. Let’s see how they work and benefit you.
Gas-Powered Water Heating Systems
How do they work?
- Gas storage water heating systems make use of a gas burner to continually heat and preserve water in a tank at 60 degree Celsius.
- While gas continuous-flow water heating systems also make use of a burner that ignites only when you need hot water.
How are they beneficial?
Gas hot water systems will generate fewer greenhouse gas emissions. Besides, depending on where you live, gas water heating systems are normally regarded to have lesser usage rates compared to electricity, thus, making them a more affordable and viable option in the long term.
Electric-Powered Water Heating Systems
How do they work?
- Electric storage water heating systems heat the water with the assistance of an electric-powered element that rests at the bottom of the water tank.
- While electric instantaneous heating systems work identically, but the element is coiled around the pipes instead, to quickly heat the water inside on demand.
How are they beneficial?
When you use hot water systems, it can help you to lower your water heating system’s energy consumption by up to 90 per cent. As hot water systems are particularly energy-hungry, you can save over your energy bills substantially. Moreover, certified solar systems might also be entitled to STC rebates from the federal government through the clean energy regulator and other state-specific rebate schemes. Besides, solar water heating systems are one of the most environmentally-friendly alternatives available on the market currently.
Electric hot water heating systems have comparatively low costs upfront and are a dependable way to keep your water warm. Most of the big electric storage water heating systems are attached to controlled load tariffs and perform most of their heating at off-peak periods* to assist lower your energy bills.
*Off-Peak Periods: Off-peak refers to reduced, discounted electricity rates during the particular time duration. Off-peak time durations are normally when residential homes and businesses use less electricity. It depends on your meter type and location, but usually, it’s during night or weekends.
Heat Pump Water Heaters
How do they work?
Heat pumps contain a fan that absorbs warm air into the system, which is then transmitted to the water storage tank. So it’s a reverse refrigerator; instead of, pumping out warm air, to keep your refrigerator cool, it pumps warm air in, to heat the water.
How are they beneficial?
One of the most energy-competent hot water solutions, heat pumps also runs on electricity but they are nearly three times more competent than conventional electric water heating systems.
Solar-powered water heating systems
How do they work?
Solar water heating systems are storage units that produce heat from the sun using solar panels that are installed on the property’s roof. This heat is utilised to warm up and preserve the water in your tank. When there is inadequate solar produced then systems can be supercharged to a temperature of 60 degree Celsius by either natural gas boosters or electricity. Moreover, solar water heating systems can either be a combined system or spilt-system.
How are they beneficial?
When you use hot water systems, it can help you to lower your water heating system’s energy consumption by up to 90 per cent. As hot water systems are particularly energy-hungry, you can save over your energy bills substantially. Moreover, certified solar systems might also be entitled to STC rebates from the federal government through the clean energy regulator and other state-specific rebate schemes. Besides, solar water heating systems are one of the most environmentally-friendly alternatives available on the market currently.
What Size Hot Water System Do You Need In Australia?
While buying storage heaters, you need to consider the number of people, going to use it at the same time, in your home. Whereas, continuous-flow water heaters size has to be determined by total outlets that will be used at the same in your home. For instance, if everybody in the household shower at the same time of the day – say, for instance, morning, you may need a larger storage tank to make sure you don’t go out of hot water. Bear in mind, larger the tank, greater would be the standing heat loss, so look for the smallest tank that will fulfil your requirements in the best possible way.
An illustrative table is shown below indicating the size of water heater you’ll need depending on the number of people who will be using hot taps at a given point of time. However, always ask the manufacturer/supplier for particular size guidelines for the products you’re planning to purchase.
| Storage | Instantaneous |
| Number of people | Size (litres) | Number of hot taps used
at the same time | Flow rate
(litres per minute) |
| 1-2 | 90 | 1 | 16 |
| 2-4 | 130 | 2 | 20 |
| 3-5 | 170 | 3 | 24 |
| 4-6 | 200 | 3+ | 32 |
| 5-9 | 270 | | |
Note: Table information is taken from energyrating.gov.au
Take into account climatic conditions in your region when choosing the right water heater size.
- Storage water heaters are an efficient choice for any climate, but in colder climates, hot water usage is inclined to be higher, so it may be worth buying a greater capacity storage tank than recommended for your household size.
- If you’re planning to buy continuous-flow water heaters and if you’re living in a very cold region, then you should choose a heating system with a higher capacity than is typically suggested for your needs, as continuous-flow water heaters are restricted in how much they can increase cold water temperature level. Curtailing the flow rate can also facilitate the water to be heated to a higher temperature.
Hot Water Heater Fuel Types
- Off-Peak Electricity
Typically, off-peak electricity can be used during night hours till early morning hours. At times, off-peak electricity can get a second boost during the day time. This is comparatively cheaper, means to operate your hot water system. Nevertheless, it may not be an environmentally-friendly option.
- Electricity – Continuous Power
Again, not a very environmentally-friendly option and it is also costly to operate. If continuous electricity fuel source is the only available option then you must consider heat pump or solar-powered water heating systems.
- Natural Gas
The natural gas fuel source is low priced and is an environmentally-friendly option. If you want to make a switch to natural gas from any other fuel source, then consider a couple of things mentioned below:
- Is natural gas available in your region and your street?
- How long will it take to connect the natural gas and make it functional?
- LPG
Never opt for LPG, as it’s pricier and not very good for the environment. In places where only LPG is the available fuel source, it’s highly recommended choosing a heat pump.
