7 Indications that your hot water system needs some work.
The hot water failures are most of the time detected several weeks before the system stops working. Early detection of these signals is a less difficult, less expensive repair, and no cold showers.
Lukewarm Water
Never reaching full temperature. Typically a defective component or thermostat (electric) or a contaminated burner (gas). Usually a one-day part replacement.
Too fast of running out
The accumulation of sediments isolates water against the element, and lowers effective tank capacity. A professional flush can be a healing factor.
Brown Water or Rusty water
The sacrificial anode is corroded and the wall of the tank begins to rust. Early replacement of anode is years of life saved. In case the tank is perforated, it should be replaced.
Popping or Rumbling Sounds
The element has deposits of hardened minerals that trap steam. Indicates high levels of sediment and decreasing efficiency.
Around the Base of Water
It may be a leaking pressure relief valve (reparable), corroded tank (replacement) or a loose fitting. Any pool water must be inspected.
Energy Bills Climbing
In Australia, 15 to 25 percent of domestic energy is taken by hot water. A low efficiency system will consume significantly higher amounts of power to warm the same volume.
Due to the use of hot taps, sulfur smell occurs
Bacteria which reacts with the anode in the tank. It is normally removed by replacing the anode and flushing the tank.
Hot Water Problems unique to the South Head Peninsula.
Vaucluse is located on the peninsula of South Head, approximately 3.1 square kilometres and has a population of approximately 9500. It is surrounded by the Tasman Sea to the east and the Sydney Harbour to the west, implying that it is constantly attacked by corrosive salt air, on all sides. That influences the aging of hot water systems in this area.
Two Salt Exposure, Sea and Ocean
The majority of Eastern Suburbs property has been exposed to salt air on one side. Two give it to Vaucluse. Floods of moisture-laden westerlies off the water occur in properties along Wentworth Road and the harbour side. Eastern facing properties, along Diamond Bay, The Gap, and the ocean, cop onshore winds with salt spray directly off the Tasman. In the case of externally installed hot water systems, it translates to corrosion of copper pipework, gas fittings, stainless steel braiding on flexi connections and external covering of storage tanks.
We find that hot water systems wear away in Vaucluse, two or three years more rapidly than the same systems in sheltered inland suburbs such as Strathfield or Epping. A shorter servicing period can make a significant difference to the duration of your unit service should your unit be installed outside, on a side terrace, beside the garage or on a balcony.
Heritage Properties and Vaucluse House–Era Homes
One of the old suburbs of Sydney is Vaucluse. The historic Vaucluse House is 1803 and lots of homes in the suburb are of heritage listing with the Woollahra Council or the Waverley Council, Vaucluse is located in both the Waverley Council and the Woollahra Council. The heritage home hot water systems are frequently installed in areas where they did not originally exist, laundry cupboards, under stair alcoves, narrow service corridors. The replacement of a system implies meticulous sizing, innovative routing of the pipework and in some cases, bespoke solutions to fit within the building constraints without compromising heritage character.
Families That Have Children of Growing Age
Vaucluse has a high number of children aged between 10 and 19 years, with the number of couples with children constituting a majority of the household structure. It translates to using a lot of hot water, numerous showering sessions in the morning, bathing small children, sports washing machines, dishwashers after dinner. Households that have been living on an undersized or failing system do not realise how much of a difference a correctly sized replacement can make until they get one.
The Energy Cost Reality
A typical electric storage tank would cost about 600-1200 dollars a year to operate in a household of four people. Gas sits around $350 to $600. Since a heat pump does not produce heat, only transfers its heat to a lower temperature, its cost is only $150 to $400 per year (a savings of 450-900/year). With NSW government rebates of $1,000 to $2,500, a heat pump will pay back in four-six years, and provide another six-ten years of net savings. The maths is especially strong with Vaucluse families who shower their teenagers in the morning until they are dry.
Repair or Replace, How We Help You Decide.
Repair When Generally Makes Sense...
The system is less than 8 years old and the fault is one component, thermostat, element, gas valve, ignition module, anode or tempering valve. These are some of the items we have on the van. Repair costs 180-450, an hour or two, and provides the system with several additional years of use.
Replacement is a Good Idea When...
The tank is leaking from the body. The system is over 10 years old and repairs are becoming frequent. There has been an increase in energy charges. Or the system has a part that is no longer in use. In the Vaucluse, which is experiencing external systems corrosion on the coast, the tipping point of replacement can be achieved much earlier than in suburbs. We will always tell you what is more economically viable in your case with one or the other choice.
