Dux gas hot water heater repairs

dux gas hot water heater repairs

Dux hot water. All Sydney suburbs.

We were contacted by a customer at Rockdale (St George area, Sydney) with a leaking Dux gas hot water heater.  Over the phone, we instructed the customer how to turn off their water supply to prevent more water leaking. Our Rockdale hot water specialist, Steve, was just finishing another hot water heater repair close by so was onsite within the hour.

Once onsite, Steve ran a series of tests on the customer’s existing Dux gas HWS. He found multiple problems, most significantly, the internal storage tank had corroded and, hence, the leak.

The system was 15+ years old and, unfortunately, parts for a hot water system of this age are very hard to find.  Often, it works out more cost-effective to replace the old HWS with a new one that is more economical to run and suited to the household hot water usage requirements.

Hot water system upgrade

After discussing the customer’s hot water usage requirements, we recommended a new Vulcan 135 litre gas hot water heater (Model Vulcan 648135NO). The customer wanted the best value for money for their requirements and the Vulcan 135 litre was the perfect product for their budget.

Tailored advice. Value for money.

The new hot water system was installed in the same location as the previous one so no additional piping or electrical work was required, saving both time and money.

When a customer’s old hot water system is beyond repair, it’s the perfect opportunity to upgrade to a more energy efficient model that better suits their household hot water usage requirements.   This not only includes their hot water usage needs now, but also those that may be required in the future. For example, as small children grow into teenagers, they invariably use more hot water.

Additionally, we don’t just consider the hot water usage of the ‘humans’ in the house but those of appliances such as washing machines and dishwashers which can use as much hot water as one person.
