Can you get instantaneous electric hot water single-phase?
Yes, instantaneous electric hot water systems, also known as tankless electric water heaters, can provide hot water on demand, without the need for a storage tank. These systems heat water as it flows through the unit, using an electric heating element.
They are more energy efficient than traditional storage tank water heaters, because they do not have to continuously heat and maintain a large tank of water at a set temperature. They also have the advantage of providing hot water instantly, eliminating the wait time for a storage tank to heat up.
However, instantaneous electric hot water systems are generally not as powerful as gas-powered tankless systems, and may not be able to provide enough hot water for large households or commercial buildings.

What is a single-phase electric water heater?
A single-phase electric water heater is a type of water heating system that uses electricity as its power source and only has one phase of electrical power.
This means that the electrical power supply to the heater only has one alternating current (AC) waveform, as opposed to a three-phase system, which has three separate AC waveforms.
Single-phase electric water heaters are typically used in residential and small commercial settings. They are easy to install and maintain but are less efficient than three-phase systems.
Can you run a 3 phase water heater on a single phase?
It is technically possible to run a 3-phase water heater on a single-phase power supply, but it may not be the most efficient or cost-effective option and we don’t recommend it.
Three-phase water heaters are designed to be used with a 3-phase power supply, which provides more consistent and reliable power. When running a 3-phase water heater on a single-phase power supply, it may not be able to function at its full capacity or may experience power fluctuations.
Additionally, the cost of converting the electrical system to support a 3-phase water heater on a single-phase power supply may be significant. It’s recommended to check with the manufacturer or a licensed electrician to see if it is possible and if it makes sense in terms of cost and efficiency.
Is it cheaper to run single-phase or 3 phase?
It is not definitely clear whether it is cheaper to run a single-phase or 3-phase electric water heater, as the cost depends on various factors such as the size of the water tank, the temperature setting, and how often the water is used.
However, Three-phase power systems are less expensive to run over time when compared to single-phase, but the cost of electricity and the efficiency of the hot water system also play a role in determining the overall cost.
How much do instantaneous electric hot water systems cost to run in Melbourne?
The running costs vary based on the model of electric hot water system. To find what a system costs to run, you need to know how much electricity it uses. This is measured in kWh.
How do you calculate kWh on a hot water system?
The amount of kWh a hot water system will use depends on the water tank size of the system, the temperature setting, and how often the water is used. For example, a 125-litre tank at 55 degrees Celsius that’s used twice a day will use about 3 kWh per day.
What is the lowest kWh hot water system?
Hot water systems vary in energy efficiency. A low Btu input system generally uses between 2 and 4 kWh per day, while a high BTU input hot water system can use as much as 7 or 8 kWh per day.
The cost of 1 kWh of electricity in Melbourne is $0.20. Assuming the water heater uses 5 kWh per day, that adds up to $1 per day or $7 per week.
To calculate the kWh usage of a hot water system, you can use the following formula: (Tank size in gallons x 12) x (Temperature Rise in °F) ÷ (Efficiency rating of the system) x (Number of hours of use per day).
This will give you an estimate of the number of kWh the system will use per day. To calculate the monthly or annual cost, you will need to multiply the daily usage by the cost of electricity per kWh, which varies depending on location and time of use.
In Melbourne, you can check the cost of electricity per kWh on your utility bill or by contacting your electricity provider. Additionally, you should consider the type of instant hot water system you are using, as some models may be more energy efficient than others, which will affect the running costs.
What is the main disadvantage of using a single-phase electric instant hot water system?
The main disadvantage of using a single-phase electric instant hot water system is that it may not be able to handle high demand household. Since instant hot water systems heat the water on demand, they require a lot of power to do so.
A single-phase electric instant hot water system may not be able to provide enough power to heat the water quickly enough to keep up with high demand. This can lead to a lack of hot water, or water that is not hot enough. A three-phase electric instant hot water system would have a higher recovery rate, making it a better option for households with high hot water demand.
Additionally, a single-phase instant hot water system may have a lower flow rate, which means it may not be able to deliver water as fast as a three-phase system.
The main advantage of using a single-phase electric instant hot water system is that it is energy efficient, as it heats water only when it is needed and does not waste energy keeping a tank of water hot when not in use.
Additionally, since it does not require a storage tank, it takes up less space in the home. It also eliminates the potential issues associated with a storage tank such as corrosion, leaks, and the need for regular maintenance.
Furthermore, it is a great option for smaller households with lower hot water demand, as it can provide hot water on demand while minimising energy consumption.
What are the pros and cons of using single-phase electric hot water?
