Hot Water Systems

If your system is no longer producing hot water, there may be an issue with the heating element, thermostat, pilot light, gas supply or electrical components. A lack of hot water is one of the most common signs your system requires urgent attention.

Leaks around your hot water unit should never be ignored. Water pooling near the tank may indicate corrosion, pressure valve failure, damaged pipework or a cracked storage tank. Early repairs can help prevent significant water damage to your property.

Brown, rusty or discoloured hot water can be a sign of internal corrosion inside the tank or deteriorating pipework. If left untreated, corrosion can eventually lead to leaks or complete system failure.

Reduced hot water pressure may be caused by sediment build-up, blocked pipework, failing valves or issues within the hot water system itself. Low pressure can affect showers, taps and appliance performance throughout your home or business.

Banging, rumbling, popping or hissing sounds are often caused by sediment build-up inside the tank. Over time, this build-up can reduce efficiency, increase running costs and place additional strain on the system.

An ageing or inefficient hot water system may use significantly more electricity or gas than necessary. If your energy bills are rising without explanation, your system may be working harder than it should to maintain water temperature.

If your hot water constantly fluctuates between hot and cold, it could indicate a failing thermostat, heating element, tempering valve or internal system fault. Inconsistent temperatures can affect comfort, safety and overall system reliability.

Most hot water systems have a lifespan of around 8–15 years depending on the type, maintenance and usage. Older systems are more likely to experience breakdowns, reduced efficiency and costly repairs.

If your household is suddenly running out of hot water faster than usual, your system may no longer be heating or storing water effectively. This can indicate sediment build-up, worn components or an undersized system for your household needs.

A hot water system that takes longer than normal to heat water may be struggling due to ageing components, heating element issues or reduced efficiency caused by internal wear and sediment accumulation.

For gas hot water systems, a pilot light that repeatedly goes out can indicate problems with the thermocouple, gas supply or burner assembly. These issues should always be inspected by a licensed gas fitter.
