Dux electric storage tanks are not only manufactured for the Dux brand other brand both past and present have also used the Dux manufactured electric storage heater. Thermmann and Apricus use Dux manufactured electric storage tanks. Conergy and some of the older brands used Dux manufactured tanks at some time during their existence.

Dux have been involved in the Australian hot water industry since 1915. They have seen many changes over the years but are committed to producing high quality products and to the on-going development of new products.

Servicing of your hot water system every four to five years, depending on the system, can considerably increase your hot water system's life span. Where stainless steel, systems require less servicing. Steel or glass lined hot water tanks do require important five year minimum services.

Four to five year service on all DUX hot water systems generally includes:

  • Replace PTR (hot water expansion valve) - stainless and steel tanks
  • Replace EVC if required - stainless and steel tanks
  • Check Tempering valve
  • Check the heating element's resistance and replace only if required. - stainless and steel tanks
  • Check the hot water thermostat- stainless and steel tanks 
  •  Replace the hot water anode. This is for steel tanks only. The reason we replace the anode in a steel tank is because it is a sacrificial anode. This means it has been designed to break down to protect the inside of you glass lined steel hot water tank. The anode is made up of a weaker metal, it basically corrodes before you tank does.

If your Dux hot water system has a major leak and needs replacing call us today.

Some residential units will have a 50L or 80L electric model in the kitchen, laundry or a cupboard. These are great for one to two people, however you should be mindful that you may have limited hot water with this size system. If you have enough space or a bigger household, the best decision is to consider installing 125L or 160L system.

Most 3 to 4 bedroom houses would have the bigger tanks, 250L, 315L or the 400L models. Usually these electric hot water systems are connected to off-peak electricity supply which gives a cheaper rate of electricity. Off peak supply is only available in times of low energy use - usually the middle of the night, heating and storing your water for use the next day. The larger electric hot water heaters can be twin element, so if you run out of hot water outside off-peak times, the top element will provide some hot water for you.

Households who have solar power that receive low feed in tariffs are sometimes best to install a timer on their hot water element. This means the times when the hot water is heated can be controlled if installed on the correct tariff. The hot water system's element can be turned on during the middle of the day when the solar power system is producing the most amount of excess power. Rather then send this power back to the grid for 8 cents or less, the excess power heats your hot water system at the cheapest rate. 

Dux Airoheat heat pumps can also be a suitable solution
