What Is An Electric Hot Water System?
An electric hot water system heats water using one or two electric heating elements inside an insulated storage tank. A thermostat controls the element, switching it on when the water temperature drops below a set point and off again once it’s reached. The tank stores the heated water until it’s needed.
Electric storage systems are straightforward in design, which is part of why they’re so widespread — they require no gas connection, no flue, and relatively little installation complexity. They come in a wide range of tank sizes and can be installed indoors or outdoors depending on the property.
The main trade-off is running cost. Because they use electricity directly to generate heat, electric storage systems are more expensive to run than gas or heat pump alternatives. However, they remain a practical and cost-effective choice in the right circumstances — particularly for smaller households, all-electric properties and homes with rooftop solar panels.
Benefits Of An Electric Hot Water System
Is An Electric Hot Water System Right For Your Property?
Common Electric Hot Water Faults We Repair
We diagnose before we quote
Every fault traced to its actual cause — no guesswork.
Failed Heating Elements
The most common electric hot water fault; the element burns out and the system stops heating or heats slowly.
Thermostat Failure
The thermostat fails to regulate temperature correctly, resulting in water that is too hot, too cold or inconsistent.
Circuit Breaker Tripping
An electrical fault, moisture ingress or failed element causes the system to trip the circuit breaker repeatedly.
Pressure Relief Valve Issues
The valve leaks, drips or fails to operate correctly, often a sign of pressure or temperature problems within the system.
Tempering Valve Failure
The valve that blends hot and cold water to a safe delivery temperature wears or fails.
Leaks From Valves, Connections Or The Tank
Particularly common in older systems approaching end of life.
Anode Rod Deterioration
The sacrificial anode that protects the tank from internal corrosion depletes over time and needs replacing.
Sediment Build-Up
Mineral deposits accumulate inside the tank over time, reducing efficiency and potentially damaging the element.
Internal Tank Corrosion
Once the tank begins corroding internally, replacement is typically the only viable option.
Electric Instantaneous Unit Faults
Heating element failure, flow sensor issues or pressure fluctuations preventing the unit from activating correctly.
If your electric hot water system has stopped heating, is tripping the power, leaking, producing rusty water or simply not keeping up with household demand, our technicians can identify the fault and advise whether a repair or replacement makes better sense.
