The Hot Water Brands We Install And Repair
Real units from recent Sydney jobs, from electric tanks in cupboards to continuous flow gas on the wall. We also repair and replace Solahart, Zip, Beasley and Aquamax systems.
Rheem Hot Water Systems
Leaking or cold Rheem hot water systems, from electric tanks like this one to gas continuous flow, repaired or replaced.
Rinnai Continuous Flow
Rinnai continuous flow units that will not fire up, run hot and cold, or show an error code, repaired or replaced.
Dux Electric Tanks
Dux electric storage tanks like the Proflo, checked when they leak or run out early, and replaced when a repair is not worth it.
Vulcan Storage Tanks
Small Vulcan electric tanks tucked into cupboards and laundries, with the relief valve, element or thermostat fixed, or the tank replaced.
How Bad Is Your Water Heater Problem?
Three hot water problems we get called about, whatever the brand, and what to do about each.
Water Pouring From The Unit
Water running from the tank, the relief valve drain or the pipes under a continuous flow unit. Turn off the cold water valve to the unit, switch off its power or gas, and call.
No Hot Water Or An Error Code
A cold shower or a code on the controller often comes down to one part, like an element, a thermostat or an igniter. Note the code and the model, then book a hot water repair.
Old, Rusty Or Running Out
Rust on the tank, or hot water that runs out sooner than it used to, is worth a look before the tank lets go. We tell you whether it is a repair or time to replace it.
How We Handle Your Water Heater, Whatever The Brand
Every brand has its own parts and setup, so we check what you have before anything is priced.
Licensed plumbersCheck The Make And Model
We read the brand, model and age off the unit, whether it is a Bosch continuous flow on an outside wall or a tank in the laundry, and find what has failed.
Fixed price firstRepair Or Replace, Priced First
You get one fixed price for the repair, or for a new system when the old one is past it, and the choice of brand is yours.
Tested before we leaveFit, Fill And Test
We fill the system, run hot water at the taps, check every joint for drips, and take the old unit away if we replaced it.

- No Call-Out Fee*Having a plumber come out to check a Rheem, Rinnai or Dux that has stopped working costs you nothing during business hours. You only pay for work you have said yes to.
- Pay Later At 0%A new hot water system rarely fits the budget the week the old one gives out. Spread the fixed price over a 0% interest payment plan and get hot showers back now.

Hot Water Heater Brands FAQs
Answer:
Yes, along with the type and size. A small electric tank, a large gas storage tank and a continuous flow unit all price differently, and each brand prices its models differently too. You get one fixed price for the unit and the installation, and you approve it before any work starts.
Answer:
No. In NSW, connecting a hot water system to the water supply is licensed plumbing work, and connecting gas needs a licensed gas fitter. You are welcome to choose the brand and model, and we will tell you whether it suits your home before you buy.
Answer:
There is no single right brand for every home. The choice comes down to whether you have gas, how many people use hot water, and where the unit has to go. We look at your setup and tell you which systems suit it before you pick.
Answer:
Yes. As well as Rheem and Rinnai, we service Dux, Bosch, Vulcan, Thermann and Aquamax hot water systems. Tell us the brand and model when you book so we can check whether a part needs ordering.
Answer:
Repair makes sense when the tank is sound and a part like an element, thermostat or valve has failed. A tank leaking from its body cannot be patched, so it needs replacing. We tell you which on the spot and price both where it makes sense.
Answer:
Yes. The new system does not have to match the old brand. What matters is the fuel type, the size and the connections, and any pipework changes are part of the fixed price we give you before we start.
Answer:
Yes. The fixed price can be spread over a 0% interest payment plan, so you can get the hot water back on now and pay it off over time.
Answer:
The brand and model from the label on the unit, whether it runs on gas or electricity, roughly how old it is, and what it is doing. A photo of the unit and any error code helps us bring the right parts.
