Hot Water Repairs in Melbourne


A cold shower is the fastest way to find out your hot water system has failed. BM Heating & Cooling repairs all types of hot water systems across Melbourne, from our base in the northern suburbs. We diagnose the real fault, fix it with quality parts, and get the hot water back on quickly.

We repair gas storage, electric storage, continuous flow, heat pump and solar hot water systems, and we work on all the major brands, whether you bought the system from us or not. Gas work is carried out by a licensed gasfitter, and we tell you honestly when a repair is worth it and when a replacement is the smarter move.

We repair hot water systems throughout Reservoir, Preston, Bundoora, Thomastown, Epping, Coburg, Brunswick, Heidelberg, Northcote and right across the Melbourne metro area.

The Hot Water Faults We Fix


We repair the common faults across every type of hot water system.

No hot water: a tripped isolator or breaker, a failed thermostat or element on electric units, a pilot or ignition failure on gas, or a controller fault on continuous flow and heat pump systems.

Not hot enough or runs out fast: a failing thermostat, sediment build-up shrinking the tank's usable capacity, or one of two elements gone on an electric unit.

Leaks and rusty water: a weeping relief valve or a pipework leak is usually repairable, but water from the tank body itself means the tank has corroded and needs replacing. Rusty or discoloured water points to a spent anode rod.

Pilot out or error codes: a faulty thermocouple on gas storage, or an error code on a continuous flow or heat pump unit flagging ignition, flame, fan or sensor faults, which we read before we arrive so we bring the right parts.

How We Repair Your Hot Water


We diagnose first so we fix the actual fault, not just the symptom.

Diagnosis: we inspect the unit, test the power or gas supply, read any control-panel error codes, and check pressures and temperatures to tell a component fault from a failed tank.

Component replacement: we replace elements, thermostats, thermocouples, the temperature-pressure relief (TPR) valve, tempering valves, anode rods, gas valves and sensors. Gas work is done by a licensed gasfitter, and we confirm the tempering valve is holding water to your bathroom at a safe maximum of 50 degrees.

Honest assessment: if it is a leaking tank on an old system we will tell you plainly, rather than sell you a repair that only buys a few more months.

Why Choose BM Heating & Cooling


Fast Response

No hot water is an urgent job, so we prioritise it and aim to get to most Melbourne repairs the same day.

All Types & Brands

Gas, electric, continuous flow, heat pump and solar, across every major brand, no matter who installed the system.

Honest Repair or Replace

We assess whether a repair or a rebated heat pump upgrade is the better value, and give you straight advice with no pressure.

Repair or Replace, and the Brands We Fix


Storage hot water systems typically last 8 to 12 years. Under about 8 years a one-off repair is normal, but past 10 to 12 years with repeat faults, a repair on an old tank often only buys another year or two.

A leaking tank body cannot be repaired and means replacement, and we will treat it as urgent to avoid water damage. When replacement is the better call, it is the right moment to consider a heat pump, which can qualify for the Solar Victoria hot water rebate and a Victorian Energy Upgrades discount while cutting running costs.

We repair all major brands regardless of who installed them, including Rheem, Rinnai, Dux, Vulcan, Bosch, Aquamax, Thermann, Chromagen, Reclaim and Sanden, and we will explain your replacement options honestly if that is the smarter spend.

Hot Water Repairs FAQs


Check the isolator switch or circuit breaker on electric and heat pump units, or that the pilot is lit on gas. If power and gas are on and it is still cold, it needs a technician, commonly a failed element, thermostat or thermocouple.

Most storage systems last around 8 to 12 years, and continuous flow can run longer. Past that, repeat faults usually mean it is time to replace.

Under about 8 years, repair. Over about 10 years, with repeat faults, or with a leaking tank, replacement is usually the better value.

A dripping relief valve is often repairable, but water from the tank body means the tank has failed and needs replacing. Either way, get it looked at promptly to avoid water damage.

Usually sediment build-up shrinking the effective tank capacity, a failing thermostat or element, or the unit being undersized for your household. A flush or a component replacement often fixes it.

The sacrificial anode rod has likely worn out and the tank interior is starting to corrode. Replacing the anode early can extend tank life.

Codes flag specific faults such as ignition failure, flame loss, or a fan or sensor fault. We read the code before arriving so we bring the right parts.

Yes. Gas, electric, continuous flow, heat pump and solar, across all major brands including Rheem, Rinnai, Dux, Vulcan, Bosch, Aquamax, Thermann, Chromagen, Reclaim and Sanden, regardless of who installed the system.
