    Hot Water System Installation & Repair in Melbourne

    No hot water is one of those problems that goes from inconvenient to urgent inside a single morning. MB Plumbing Services Pty Ltd offers fast, professional hot water system installation, replacement, and repair across Melbourne, with most jobs completed within 24 hours of your call. Whether your existing unit is leaking from the bottom, has stopped producing hot water, is making noise, or is simply old enough that replacement makes more sense than another repair, our licensed plumbers and gas fitters handle the full job, supply through to commissioning. We work across every system type, including gas storage, continuous flow gas, electric storage, heat pump, and solar hot water, and we install all major brands including Rheem, Rinnai, Dux, Aquamax, Vulcan, and Bosch.

    Common Hot Water Problems We Fix in Melbourne

    Hot water units rarely fail without warning. Spotting the signs early often means a repair instead of a full replacement. Here's what we see most often:

    • No Hot Water at All: Pilot light out, faulty thermostat, blown element, or tripped circuit. Often a same-day repair.
    • Hot Water System Leaking from the Bottom: Usually a sign the internal tank has corroded through. Replacement is almost always the right call here.
    • Lukewarm Water or Running Out Quickly: Failed thermostat, broken dip tube, sediment build-up, or an undersized unit for the household.
    • Banging, Rumbling, or Hissing Noises: Sediment hardening on the heating element. Flushing the tank often fixes it; in older units it signals end of life.
    • Discoloured or Smelly Hot Water: Anode rod failure or bacterial growth in the tank. Both are fixable without full replacement in most cases.
    • Pilot Light Won't Stay Lit: Faulty thermocouple or gas valve. Usually a quick repair on gas storage and continuous flow units.
    • Pressure Relief Valve Constantly Dripping: Failed valve, excessive mains pressure, or expansion issues. Cheap to fix early, expensive to ignore.

    If your unit is leaking onto the floor, switch off the power or gas at the isolator and call us straight away to limit water damage.

    Frequently Asked Questions

    In almost every case, no. A leak from the base of a storage unit means the inner tank has corroded through, and there's no patch repair that's safe or lasting. The right move is replacement, ideally within 24 hours to limit water damage to flooring, walls, or your subfloor. We carry common storage units in our vans and can usually replace your unit the same day you call.
    It depends on the type. Gas and electric storage units typically last 8 to 12 years. Continuous flow gas systems often run 15 to 20 years. Heat pumps generally last 10 to 15 years, and solar systems can run 15 to 20 years for the panels with the storage tank lasting 10 to 15. Anode rod replacement every five years can extend storage tank life noticeably. If your unit is over 10 years old and starting to fail, replacement usually makes more sense than another repair.
    It depends on the system type and capacity, the brand, whether the install location stays the same, and whether any pipework, gas line, or electrical work needs upgrading to current code. Like-for-like swaps of standard gas and electric units are at the affordable end, while heat pumps and solar systems cost more upfront but pay back through lower running costs and rebates. We provide a fixed written quote after a quick on-site assessment, with the supply, install, removal of the old unit, and compliance certificates all included.
    Yes to both. Electric to gas usually requires a new gas line to the unit location and a flue setup if going with storage. Gas to heat pump is straightforward where the existing electrical supply is adequate, and heat pump systems are eligible for Victorian Energy Upgrade rebates that significantly reduce the upfront cost. We assess the cheapest install path and the long-term running cost before recommending a system, so the decision is based on what actually saves you money over the next decade rather than just what we have on the van.
