No hot water? Don’t despair – call us now: 1300 87 50 20

If your hot water heater has “burst” or is leaking from the top or any other part of the casing, turn the cold water inlet control tap off. This is sometimes a t-headed tap near the bottom of the heater but more commonly now will have a round, black plastic handle. In either case, turn the handle clockwise until tap is off. If you cannot get close enough to the tap without getting wet or scalded, turn the water off at your water meter first. Then turn off the gas supply to the water heater, or power, whichever the case may be. Lastly, please call Hot Water Systems Perth to have the water heater replaced.

This is normally an early sign that the inner lining of the steel hot water cylinder has eroded and that failure of the integrity of the cylinder is imminent. Please call Hot Water Systems Perth and if the water heater is located inside the house, do not wait too long before taking action, due to a higher risk of water damage.

If it is just the one tap, make sure that it is not a jammed tap washer in the tap itself or a blocked aerator in the spout. If you have no water at any hot taps, it could be that the dual control/check valve on the inlet to the tank is faulty and needs replacing. If you have a gravity-feed tank in the roof, the tank could be empty due to a stuck or faulty inlet valve, (not filling the tank correctly), or faulty solenoid valve. In any of these situations, please call Hot Water Systems Perth.

It is normal for water to drip from the temperature and pressure relief valve when the system is heating because water expands as it is heated. If the valve drips or runs continuously, the hot water temperature and cold water inlet pressure needs to be checked. If the water is too hot, the thermostat needs to be adjusted or replaced. If the inlet pressure is too high, the pressure limiting valve should be checked or replaced. If both valves are fine, then the temperature and pressure relief valve is at fault.

Check that the heater is plugged into the outdoor powerpoint and that the powerpoint is working. If you have a temperature controller inside the house, check that it is switched on. Normally after a blackout or after power has been shut off, you will need to swich the unit on via the controller. This is not necessary if a controller was not included in your installation. If everything seems fine, check that you have gas to the rest of the house and, if you still can find nothing wrong, please call Hot Water Systems Perth.

It could be that your thermostat, (gas or electric), or your element (electric), is faulty and needs attention. Another possibility is that the relief valve on the tank is releasing a lot of water or you have a burst hot water pipe. In these cases, hot water is escaping and the heater cannot keep up with the loss. Depending on the fault and the age of the heater, you have the option of making repairs or replacing the water heater. Talk to us at Hot Water Systems Perth for further information.

Have you checked the fuse or circuit breaker for your hot water heater? If the fuse is unbroken, you may have a dead element or thermostat. If the fuse has blown, you may reset it, but it is more than likely that an electrical fault, such as a faulty element and/or thermostat, has caused the tripped fuse and the problem will reoccur. Depending on the age of the heater, you have the option of repairing or replacing the water heater.

Has the pilot light gone out? Follow the instructions, (usually found on the inside of the burner cover), to relight the pilot light. If the pilot light will not stay lit, you may have a faulty flame failure device or thermostat control valve. Depending on the age of the heater, you have the option of repairing or replacing the water heater.

Every household is different in terms of its requirements and plumbing setup, so it is always best to speak with one of our plumbers at Hot Water Systems Perth about your specific situation. However, below are some general points to consider:

  • With storage electric hot water systems, it can be possible to take advantage of ‘off peak’ electricity tariffs which can reduce electricity costs by only heating the water during off peak times. It is important to note here that a large enough storage tank is required to ensure you do not run out of water when you need it.
  • Also, if you are to be away on holidays for an extended period of time it is always advisable to turn off the electricity supply to your electric storage hot water system. This is usually found in your electrical meter box.

Every household is different in terms of its requirements and plumbing setup, so it is always best to speak with one of our plumbers at Hot Water Systems Perth about your specific situation. However, below are some general points to consider:

  • If looking at replacing your existing gas hot water system then the best way to ensure lower heating costs in the future is to make sure you select a higher efficiency rated hot water systems. Remember to look at how many stars (efficiency) the model has.
  • Also, if you are to be away on holidays for an extended period of time it is always advisable to turn the gas off to your gas storage hot water system. This is done either by a gas control valve next to your heater or by turning the heater control knob to ‘off.’ This is usually found inside the burner cover. On returning home, follow the instructions to re-ignite your heater which are usually located on the inside of your burner cover.

Cost effectiveness in terms of repairing or replacing your hot water system can depend a great deal on the age of your heater. Replacement parts and servicing can be expensive. We recommend you consider the age and condition of your hot water system before you authorise a service. Sometimes these costs go a long way toward the cost of replacing your heater with a new system, complete with warranty and peace of mind. Please contact Hot Water Systems Perth for more information..
