Hot Water System Repairs & Servicing Costs: 2025 Guide
When your hot water system stops working or is taking too long to heat up for a shower, it’s time to call in a professional to take a look at what’s causing the problem. A hot water system can last anywhere between 8 to 20 years (depending on the make and model), during which it may need routine servicing or spot repairs to keep the system in good working order.
If your hot water system simply needs repairs and is not due to be replaced, a qualified electrician or plumber will be able to identify the problem and address the issues directly – whether it be a faulty pressure relief valve or burnt-out wiring. So, how much can you expect to pay for hot water system repairs? Here’s a guide to the costs involved.
Average Cost of Hot Water System Servicing
Hot water system repairs in Australia generally cost between $140 and $200. The costs will also change depending on who you book, and the extent of repair work. Hot water system servicing will require the expertise of a licensed plumber or electrician (for electric hot water systems).
Additional costs may be involved for emergency call-out services or replacement parts needed to complete the repair.
Factors Affecting Hot Water System Repair Costs
The cost of hot water system repairs can vary based on a range of factors, including labour costs, the type of hot water system, and the components that need replacement.
Cost of Labour
The labour costs for hot water system repairs will come down to the provider you choose. Each plumber or electrician has their own hourly rate. On average, electricians in Sydney charge between $80 and $130 per hour.
Hot water system services usually don’t take long; most repair jobs can be completed in 1 to 2 hours. Taking the median hourly rate of $100 for an electrician’s services, a typical repair job for a hot water system will cost $100-$200 based on labour charges alone.
Model and Type of Hot Water System
Hot water systems are either electric, solar or gas-powered – the work required in repairing each system will depend on the type. Electricians are required for repairing an electric hot water system, as they have the requisite experience to identify and rectify electrical issues.
In addition to the type of hot water system, the specific model of the hot water system will also affect the cost of repairs. Replacement parts may not be as readily available for less-popular or older models, which can drive up the price of parts. In some cases, servicing technicians may have to look for replacement parts from aftermarket sources, which can add to the cost of labour and time for repairs.
Replacing Hot Water System Components
The cost to replace each hot water system component will also affect the overall cost of repairs. Here’s a list of the costs for hot water system components that often need replacement:
• Heating Element: $20 – 30
• Anode rod: $40 – $140
• Thermostat: $30 – $120
• Dip tube: $50 – $150
• Pressure relief valve: $150 – $200
• Electric wiring upgrades: $300-$800 (often needed for older homes)
• Pilot light (gas-powered systems): $120 – $200
Location of Hot Water System
Hot water systems located in easily accessible areas (usually on the outside side passage of the property) will not incur any additional fees. However, if the hot water system is located in an area that is more difficult to access or requires permission (such as in a strata property) it may result in additional fees from the electrician or plumber.
Should You Repair or Replace a Faulty Hot Water System?
Repairing a hot water system will almost always be more cost-effective than replacing the system outright. However, there are instances where the hot water system may be too outdated or in such poor condition that it is not worth repairing.
As a general rule, a faulty hot water system will require replacement after 10-15 years, especially if it consistently requires repairs. Replacing a hot water system will involve a higher upfront cost, but it will be more reliable in the long run.
