Hot Water Systems Gold Coast

Often it is a part, not the whole tank. A gas system may also need gas fitting work. We look at what has failed before we suggest a new one.

Last reviewed

Vesey Plumbing Solutions repairs, replaces and services electric, gas, heat pump and solar hot water systems across the Gold Coast, Monday to Friday, 7am to 5pm. Licensed plumber and gas fitter Jamie Vesey does the work and puts the price in writing first. The QBCC lists installing or replacing a water heater as notifiable work.

What is your hot water doing?

No hot water at all

Usually a repair

What is usually behind it

On an electric system it is usually the heating element or the thermostat. Both are parts, not the tank. On gas it is more often the pilot light or the gas getting to the unit.

What you can do now

Call us. Tell us whether the system runs on electricity or gas, and what you noticed just before the hot water stopped.

0405 690 174

Not sure? Describe it on the phone.

Water or rust under the tank

Usually a replacement

What is usually behind it

The tank itself has usually rusted through. A tank in that state cannot be repaired, so patching it only delays the replacement.

What you can do now

Turn off the tap on the cold water pipe going into the tank. That stops it refilling while it leaks. Keep clear of any wet wiring. Then call us. If the water is not coming from the tank, it may be a pipe: see leak detection.

Not sure? Describe it on the phone.

It runs out part way through a shower

Usually a repair

What is usually behind it

Usually a heating element has failed or the thermostat is set too low, so only the top of the tank gets hot. If more people live in the house than when the tank went in, nothing is broken. It is simply too small.

What you can do now

Notice whether it changed suddenly or slowly over months, and tell us which when you call. They point to different causes.

Not sure? Describe it on the phone.

It never gets past lukewarm

Usually a repair

What is usually behind it

A thermostat or element on its way out, or on gas a burner that is not firing properly. Sometimes it is the valve that mixes hot and cold water for the bathroom.

What you can do now

Run the kitchen tap on hot. If the kitchen is hot and the bathroom is not, mention it when you call. That points straight at the mixing valve.

0405 690 174

Not sure? Describe it on the phone.

A pipe off the tank drips all the time

Usually a repair

What is usually behind it

That pipe drains a safety valve. A little water while the tank heats up is normal. A constant drip means the valve is worn, or the water pressure coming into the house is higher than the system is made for.

What you can do now

Never block, cap or tie off that pipe. The valve has to be able to let water out.

0405 690 174

Not sure? Describe it on the phone.

Banging or rumbling from the tank

Depends on the age

What is usually behind it

Usually minerals from the water settling at the bottom of the tank and crackling as it heats. In a younger tank a service can deal with it. In an older one it is often a sign the tank is near the end.

What you can do now

Tell us roughly how old the tank is when you call.

Not sure? Describe it on the phone.

It works, but it is getting old

Worth planning ahead

What is usually behind it

Every tank wears out in the end. Replacing one when it suits you beats replacing it on a cold weekday morning with everyone waiting.

What you can do now

If the tank is still sound, a service can add years to it. That includes a new anode once the old one wears out, a rod inside that rusts so the tank does not.

Something else

Not on the list?

Call us and describe it.

What to do

Call and describe what it is doing in your own words, and the type of system if you know it.

Repair it, or replace it?

Age decides most of it. The date the tank was made is on a sticker or metal plate on its side.

  1. Newer systems

    Usually worth repairing

    If the tank is not leaking, the fault is almost always a part: an element, a thermostat or a valve. Replacing the part is the smaller bill.

  2. Middle of its life

    Depends on the fault

    A small part is still worth fitting. A big repair on a tank near the end of its life usually is not.

  3. Old, or leaking

    Plan a replacement

    A tank that is rusty or leaking cannot be repaired at any age.

If it needs replacing, we talk you through the options. The same again, gas, heat pump or solar, and what each would cost to run.

A written price. Guaranteed workmanship.

A written price before we start, and our workmanship guaranteed for as long as you own the home.

You get the price in writing before any work begins. If we find something the quote did not cover, we stop and tell you what it means before we touch it. If our workmanship ever fails, we will repair or redo the work, whichever we judge right for the job.

Some jobs cannot be quoted without opening something up. Where that is the case, we tell you before we start.

The workmanship guarantee covers the work we carry out, for as long as you own the property. Anything we supply also carries its manufacturer's warranty, and we will help you claim on it. This guarantee is in addition to your rights under the Australian Consumer Law. How to make a claim, and your consumer guarantees.

Electric, gas, heat pump or solar

A straight swap is usually half a day. Changing type takes longer, because pipes, power or gas may need to reach a new spot.

  • Electric

    A tank with an element inside, a bit like a big kettle, kept hot around the clock.

    Simple and the cheapest to replace. The dearest to run, unless it heats on an off-peak tariff.

  • Gas

    Either a tank kept hot by a gas burner, or a continuous flow unit that heats water only as you use it.

    Continuous flow never runs out, which suits a big household. It needs gas at the spot where it goes, run by a licensed gas fitter.

  • Heat pump

    Pulls warmth out of the air and puts it into the water, like a fridge working backwards.

    Uses far less power. It costs more to buy, needs space outside with airflow, and the fan makes some noise.

  • Solar

    Panels on the roof heat the water, with electric or gas backup for cloudy days.

    Very cheap to run in Gold Coast sun. It needs roof space facing north and a roof that can take the weight.

What to tell us when you call

  • What it is doing

    In your own words.

  • What type it is

    Electric, gas, heat pump or solar. If you are not sure, say so.

  • How old it is

    Roughly is fine. The plate on the tank has the exact date.

  • Where it is

    Inside, outside, in the roof space or under the house.

Hot water questions people ask

On an electric system the usual cause is a failed heating element or thermostat, and both are replaceable parts rather than a reason to replace the unit. On a gas system it is more often the pilot, the thermocouple or the gas supply itself, which is gas fitting work. If the tank is leaking or the water is rusty, the cylinder is the problem and no part will fix that.

Whether to repair or replace a hot water system comes down to the cylinder. Repair it if the cylinder is sound and the fault sits in a part: element, thermostat, valve or anode. Replace it if the cylinder has corroded through, because a rusted tank cannot be repaired at any price. Age is the quick guide. An older unit with a major fault is usually worth replacing rather than patching.

It depends on the unit, how hard it works and the local water. Replacing the anode once it wears out adds years, because the anode corrodes so the tank does not. A system nobody looks at fails sooner, and a service shows what condition yours is in.

Size is set by how many people live in the house and whether they all want hot water at once. Peak demand matters more than total daily use, so a household of five showering in the same hour needs more storage than the same volume spread across a day. A continuous flow unit sidesteps the question by heating on demand instead of storing.

It suits a house with somewhere sensible to put it. A heat pump moves heat out of the air into the water rather than generating it with an element, so it uses considerably less electricity to deliver the same hot water. The trade-offs are a higher purchase price, outdoor airflow and clearance around the unit, and compressor noise.

A tank that empties faster than it used to usually has a failed lower element or a broken dip tube, so only the top portion of the water is being heated. A thermostat set too low does the same thing. If the household has grown and the tank has not, nothing is broken and the answer is a larger unit or a continuous flow one.

A small discharge from the pressure relief valve during a heating cycle is normal, because the valve is releasing the expansion as the water heats. A constant drip is not normal. It usually means the valve has worn or is holding grit on its seat, and it can also mean mains pressure into the house is running higher than the system is rated for.

A like-for-like replacement in the same position is usually a half-day job. It takes longer when the new unit is a different type or size, because the connections, the relief drain line and the tempering valve all have to be reworked. Changing from electric to gas can also mean a new gas line to the unit, which is gas fitting work.
