Electric Hot Water Systems

What is an Electric Hot Water System?

There are two types of electric hot water systems. They are either storage electric hot water systems, which use a storage tank, or instantaneous electric hot water systems, which use a continuous flow of hot water rather than instant hot water. Both are used to heat the water that is supplied to your home or business for showers, laundry, taps etc.

Pros and Cons of Purchasing an Electric Water Heater

Electric hot water systems are one of the most commonly used hot water heaters all over Australia. It is true that you can save water if you install an instantaneous electric hot water system because you only use the water that you need at your demand. This, however, does not hold true for storage electric hot water systems where you have to store hot water in a tank and risk heat loss while it’s on standby. We have looked at the positive side and the negative side of choosing to install an electric hot water system in your household or property:

Cost

Electric water heaters have the lowest upfront costs compared to gas, heat pump, and solar water heaters. Alternatively, electric storage water heaters have the highest operating costs because electricity is required to ensure hot water on demand.

Reliability

It goes without saying that electric hot water systems are only reliable if they are connected to electricity. The capacity of an electric hot water system determines how much water it can hold. For example, continuous flow electric hot water systems can be inconvenient when you are in a hurry and need to wait for the water to heat up.

Environmental Impact

You also avoid the combusting issues and safety risks associated with gas heating when you use an electric hot water system. Due to the longer amount of time it takes electric hot water systems to heat water, you end up paying more for electricity. Emissions of greenhouse gases are also increased.

Why is my electric hot water not working?

Your electric hot water heater may be on the way out. You’re not sure what is wrong with it but one thing for sure you have no hot water. When it comes to electric hot water systems and its faults, we have three solutions:

A hot water specialist checks the thermostat, heating elements, associated valves, fittings, and electrical supply to diagnose the cause of the hot water issue. If any of the mentioned items are defective or faulty, the Plumbing and Electrical Doctor will fix and replace them right away in order to get your hot water back and running.

We often encounter questions from customers asking us if we can do electric hot water tank repair. Unfortunately, when the tank is leaking or split, amateur tradies would try to peel off the outer tank layer or skin to weld it up. While this may temporarily fix the issue, it causes serious damage as time goes by, because the insulation is already compromised. Replacement of the old water heater tank is a better option and costs less overall. 

Tank replacement is also essential when your water heater is leaking from anywhere other than the element gasket. It’s important that you know and understand the warranties of your water heater. Most water heaters built after 2016 carry a warranty of 10 years or even up to 12 years, depending on the manufacturer or type. If your hot water system is leaking then please check out the warranty details and call the manufacturer for their warranty obligations. 

According to most hot water manufacturers, your hot water heater should be serviced every 5 years. This electric hot water maintenance service includes:

  • Examining the thermostat and heating elements
  • Testing the temperature relief valve and replacing if over 5 years old
  • Inspecting the pressure limiting valve
  • Checking the installation and other safety features of the equipment.
