Why don’t I have hot water?

Our checklist below will help you determine why you may not have hot water. 

STEP 1 – Is the electricity turned on?  Make sure the isolating switch (usually located on your electricity switchboard) is switched on.  Then make sure the hot water switch, usually next to the isolating switch, is also on.

STEP 2 – Check that the fuse marked ‘water heater’ (or similar) has not blown and is OK.

STEP 3 – If your hot water heater has a power cord, check that it is plugged into the socket, and turned on at the power point.

STEP 4 – If your hot water heater has a timer attached, make sure it’s on and has been given enough time to heat up the water.

STEP 5 – Check that your energy tariff provides sufficient time to reheat your hot water tank to meet the hot water needs of your household.

STEP 6 – Monitor how much hot water your household uses, to make sure you are not exhausting your supply.  Consult us about low flow tap valves and energy saving shower heads.  You can also purchase a cheap waterproof timer or clock and install it in your shower to keep track of usage.

STEP 7 – Check the temperature relief valve on your water heater is not discharging too much water.  Excessive amounts of water may be diminishing your hot water supply, normally only a small amount of water is discharged during the heating cycle.

STEP 8 – Speak to us about checking your hot water heaters thermostat setting to make sure it is correct for your household.  It is important that the temperature is not so hot that it scolds.

Where is my hot water heater’s temperature relief valve?

All hot water heaters have a temperature relief valve.  As water heats up, it expands and pressure is created.  The relief valve’s role is to relieve any pressure that may build up by allowing it to escape, and thus protecting the tank.

It is normal for a small amount of water to discharge from the relief valve during the water heating cycle, however, if this amount fills a bucket within a 24 hour period, it may indicate that there is a problem with your system.  We suggest you contact us to inspect your tank.

If there is a continuous dribble of water from your hot water tank (not just during the heating cycle), there may be a small particle of foreign material blocking the relief valve.  To amend this, try gently easing the relief valve lever for a few seconds. This may dislodge the foreign material and clear the blockage. Then lower the lever gently. If the water continues to dribble, contact us for more troubleshooting advice.

In the case of a steady flow of water coming from your relief vale, it may be that the water mains pressure is rising above the pressure designed for your hot water tanks relief valve.  This problem usually happens at night.  If this is the case, contact us and we can install a pressure limiting valve.  Note that the relief valve should never be replaced with one of a higher pressure rating.

How do I adjust the temperature of my hot water heater?

Australian law states that the internal temperature of a hot water heater must be set at 70 degrees celsius. This temperature is hot enough to kill harmful bacteria and cool enough to prevent scolding.

We recommend that you call in an experienced tradesman to adjust your hot water thermostat as there is a risk of electrocution, and also the potential to damage your hot water heater and  void your warranty.

A tempering valve will reduce the risk of hot water scalding

When your hot water heater has been set too high, there is a greater risk of a scalding accident.  Our experienced tradesmen can install a tempering valve to the hot water pipe running to your bathroom(s) which will keep the hot water temperature coming out of the taps below 50 degrees celsius.  This reduces the risk of scalding, but still allows the hotter water from the hot water system to flow to the kitchen and laundry.
