Water Heater Installations & Hot Water Repairs
Repair or Replace? How to Decide
| Situation | Usually the answer |
|---|---|
| System under 8 years old, minor fault | Repair — element, thermostat, valve or anode replacement |
| 8–12 years old, first major fault | Judgement call — depends on the part and the tank’s condition |
| Over 12 years old | Replace — tanks corrode from the inside and repairs won’t stop it |
| Leaking from the tank body | Replace — a leaking tank cannot be repaired |
| Rusty or discoloured hot water | Replace — the internal lining has failed |
| Repeated repairs in 12 months | Replace — you’re paying for a new system in instalments |
Common Hot Water Repairs
Plenty of hot water faults are genuinely fixable, and we repair them the same day where parts allow:
- No hot water at all — failed element, thermostat or pilot light
- Hot water running out too fast — undersized system, failed lower element or a sediment-filled tank
- Water too hot or not hot enough — thermostat calibration or a failed tempering valve
- Leaking or dripping relief valve — usually a $100-ish part, not a new system
- Water hammer or banging noises — sediment build-up or valve issues
- Pilot light won’t stay lit on gas systems
- Rusty or smelly hot water — a failed sacrificial anode, sometimes replaceable before the tank goes
Water Heater Installations
We supply and install every major type, and we’ll help you pick the right one for your household rather than the one with the best margin:
- Gas storage — fast recovery, good for larger families with mains gas connected
- Electric storage — lowest upfront cost; worth pairing with off-peak or solar
- Continuous flow (instantaneous) gas — endless hot water, compact, no standing heat loss
- Solar and heat pump — highest efficiency and eligible for government rebates
- Gas room heaters and other gas appliance installations
Every installation is completed to Australian Standards by a licensed plumber and gas fitter (Lic. No. L55), includes safe removal and disposal of your old unit, and carries our 25-year workmanship warranty.

Sizing It Right
An undersized system is the most common reason people think their hot water “isn’t working” when it’s actually working exactly as specified. As a rough guide for storage systems: 1–2 people suits 125–160L (gas) or 160L (electric), 3–4 people suits 170–200L, and 5+ people needs 250L or more — or a continuous flow unit, which never runs out regardless of household size.

FAQ
A straightforward like-for-like replacement usually takes 2–4 hours, including removing the old unit. Changing type or location — for example electric storage to continuous flow gas — takes longer as it may need new gas, water or electrical work.
Often yes. If your system has failed completely we carry common sizes and can usually have hot water back on the same day.
Storage systems typically last 10–15 years, continuous flow units often longer. Replacing the sacrificial anode every 5 years can add years to a storage tank’s life.
It never runs out and wastes no energy keeping water hot, but it needs adequate gas supply and costs more upfront. For most Shire homes with mains gas and variable hot water use, it’s the better long-term choice — but it isn’t automatic, and we’ll tell you if a storage system suits you better.
Yes — 25 years workmanship warranty on installation work, in addition to the manufacturer’s warranty on the unit itself.
