How Often Should You Service a Hot Water System?
A quick, honest guide to how often each type of hot water system needs a service — based on manufacturer guidance and 25+ years in the field.
As a rule, continuous flow and heat pump hot water systems should be serviced every 12 months, while electric and gas storage systems need a full service every 3–5 years — with the relief valve checked every 6–12 months and a sediment flush every 1–2 years. Solar systems are typically serviced around every 5 years. Here is how that breaks down by system type.
| System type | Service interval | Key tasks |
|---|---|---|
| Continuous flow / instant gas | Every 12 months | Burner & ignition check, water filter clean, gas pressure, error-code clear |
| Heat pump hot water | Every 12 months | Clean air filter & evaporator, check refrigerant operation, anode, relief valve |
| Electric storage | Full service every 3–5 years | Relief valve every 6–12 months, sediment flush every 1–2 years, anode ~5 years |
| Gas storage | Full service every 3–5 years | Relief valve every 6–12 months, burner & pilot check, anode ~5 years |
| Solar hot water | Every ~5 years | Pump, controller & booster check, anode, valves, roof collectors & seals |
Intervals are a guide — your system's age, water quality and manufacturer guidance all matter. Not sure when yours was last serviced? Call 1300 728 122and we'll help.
What's Included in a Hot Water Service
A SunCity hot water service is a full health check of your system — not just a quick look. Our licensed technicians work through the safety, efficiency and wear items that decide how long your system lasts, and give you a clear report before any repairs.
Temperature & pressure relief valve
The TPR valve is eased and tested roughly every 6 months and replaced around every 5 years — it's the single most important safety check on a storage system.
Sacrificial anode inspection
The anode rod is inspected every 2–3 years and replaced around every 5 years. A healthy anode is what stops the inside of the tank rusting out early.
Sediment flush
Flushing the tank every 1–2 years clears mineral and sediment build-up, which protects efficiency, stops rumbling noises and extends tank life.
Tempering valve check
The tempering valve that keeps your delivered water at a safe 50°C is tested and replaced around every 5 years, so your taps stay both safe and hot.
Element, thermostat & burner
Electric elements and thermostats, or gas burners, pilots and thermocouples, are checked for correct, efficient operation and replaced if worn.
Full system health check
Fittings, connections and the tank are inspected for leaks and corrosion, so small issues are caught before they become a cold-shower breakdown.

FAQs
Hot Water Servicing — Frequently Asked Questions
How often should you service a hot water system?
Do hot water systems need servicing?
Yes. Regular hot water servicing protects your warranty, keeps running costs down and prevents most breakdowns. The sacrificial anode and relief valve in particular wear out over time — left unchecked, they're the main reason a tank fails years earlier than it should.
How often should a gas hot water system be serviced?
Do solar hot water systems need servicing?
Do heat pump hot water systems need servicing?
What's included in a hot water service?
How much does a hot water service cost?
Does regular servicing make a hot water system last longer?
Yes, significantly. Most systems last 8–12 years, but a neglected anode or relief valve can halve that. Replacing the anode and flushing the tank on schedule is the single best way to get the full life — and sometimes more — out of your hot water system.
Which hot water brands do you service?
Every major brand — including Rheem, Rinnai, Dux, AquaMAX, Bosch, Vulcan, Stiebel Eltron, iStore, iHeat, Haier, Apricus, Reclaim, Midea, EvoHeat, Thermastore, OMNI X, Enviroheat and Envirosun. We also service systems we didn't install.
