Hot Water Systems Gold Coast

Cold shower this morning? We repair what we can, replace what we can't. Same-day swap-outs available.

No hot water? Three things to check first.

Before you call, try these, solves about a third of "no hot water" complaints:

  • Gas storage units: open the front panel, look at the pilot light. Steady blue flame = good. Out = needs relight (sticker inside the panel explains how; if it won't catch in 2-3 tries, stop and call us, repeated attempts release gas into the cabinet).
  • Electric storage units: check the switchboard for a tripped breaker labelled "HOT WATER". Flick it firmly off then on. If it trips again immediately, you have an electrical fault, stop.
  • Heat pump units: check the controller on the unit for an error code. Note it down before calling, tells us what's wrong before we arrive.

If those don't fix it, ring us. We carry common parts in the van so most repairs are same-visit.

Repair or replace? Here's how we decide.

Hot water systems usually last 8-12 years. Our honest decision tree:

  • Under 7 years old, small fault: repair. Cheap, quick, system has years of life left.
  • 7-10 years, repairable fault, system has been serviced: repair if it's a $200-400 part. Replace if it's a $500+ part.
  • 10+ years, tank leaking: always replace. Tank failure means the tank's gone. No repair worth doing.
  • 10+ years, small electrical fault (thermostat, element): grey area. We'll quote both options so you can decide.
  • 15+ years, anything: replace. The other components are at end-of-life too.

We don't push replacements when repair is the right call. If you want a second opinion on a unit we said to replace, get a second quote, we won't be offended.

What we install, gas, electric, heat pump, solar.

Gas storage (Rheem Stellar, Vulcan, Aquamax): traditional tank-and-burner. Reliable, simple, easy to service. Cheaper install, higher running cost than heat pump.

Gas continuous flow (Rinnai Infinity, Rheem Metro): no tank, heats water on demand. Compact, good for tight spots. Best for high peak-demand households.

Electric storage (Rheem, Vulcan, Aquamax): cheapest to install, most expensive to run. We rarely recommend new electric installs in 2026 unless heat pump won't fit.

Heat pump (Sanden, Reclaim, iStore, Rheem Ambiheat): runs like an air-conditioner in reverse, extracts heat from outside air to heat water. About 3-4x more efficient than electric. Federal STCs + QLD incentives make these very attractive right now.

Solar hot water (Solahart, Rheem Loline, Edwards): roof panels heat water directly, gas or electric booster for cloudy days. Highest install cost, lowest running cost. Best ROI if your house is already set up for it.

Which system suits your house, honest take.

What we'd put in your house, based on situation:

  • Most homes, replacing a dead system: heat pump. Take the rebate, save $300+/year. Payback 2-3 years.
  • Large family with peaky demand (5+ showers in a morning): gas continuous flow.
  • Already has solar, replacing booster: upgrade the solar tank, keep gas booster.
  • Investment property, lowest install cost matters most: gas storage or continuous flow.
  • Off-grid acreage: heat pump with adequate solar generation, or LPG storage.
  • Apartment with limited install space: small gas continuous flow inside the cupboard.

Send us a photo of your current setup + the location and we'll tell you straight what we'd install.

Heat pump rebates, why the maths is good right now.

Federal STC (Small-scale Technology Certificates) plus QLD-specific incentives can knock $1,000-$2,500 off the upfront cost of a heat pump install in 2026. A heat pump that costs $4,500 supply-and-install becomes $2,500-$3,500 after rebates.

Compared to gas continuous flow at $2,000-$2,800 with no rebate, the upfront gap shrinks to a few hundred dollars. Then the heat pump saves you $300+/year in running cost. Payback on the difference is 2-3 years.

We register every install with the manufacturer and submit the rebate paperwork on your behalf. No paperwork on you.

Same-day swap-outs.

If your system is dead and you need a new one in today, we usually can. We carry common units in the van, Rheem and Rinnai gas continuous flow, Vulcan and Rheem gas storage, common electric storage. Worst case it's a next-day install.

For heat pumps we typically schedule out 3-5 days because we don't carry them in the van, too big, and the install needs a concrete pad and electrical work coordinated. If you can survive without hot water for a few days, the heat pump is usually worth the wait.

Annual servicing, worth it?

For gas units (storage or continuous flow): yes. $150-200 a year buys you a clean burn, no carbon monoxide risk, longer unit life and warranty validity. Manufacturers like Rinnai actually require annual servicing to honour the warranty past year 5.

For electric storage: less critical. But replacing the sacrificial anode every 5 years (we do this as a service) doubles the tank's expected life from 8-10 to 15-20 years. Cheap insurance.

For heat pumps: minimal servicing required. We recommend a check at year 5, clean the air filter, verify refrigerant pressure, replace the anode in the tank.

For solar: panels and collectors need an annual rinse-and-inspect. Boosters need normal servicing.

What we don't recommend.

Some things we'll talk you out of:

  • Cheap online heat pumps from unknown brands. We've seen them fail in 18 months and the warranty is unenforceable. Stick with Sanden, Reclaim, iStore or major brand units.
  • Reinstalling an electric storage system when heat pump is an option. The rebate maths is too good in 2026.
  • Cheap solar hot water, install costs are high, cheap brands have a poor track record, payback is too long.
  • Repairing a 12+ year old gas storage unit with multiple faults. You're throwing money at a system that'll fail again soon.
