Need a New Gas Hot Water System

Has your hot water system broken down and stopped working? It’s probably time for a new one, we supply new gas hot water tanks right across Melbourne so give us a call. A new gas hot water system is more energy-efficient and runs a lot more cost-effectively than old ones so makes for less bill shock! If your hot water system is over 10 years old it may be time for a replacement. New hot water systems with maintenance every 2 years should last upwards of 15 years or more.

There may be some troubleshooting you can try first to see if it’s a problem that can be solved without getting a new hot water system.

These are some common issues we see with continuous flow hot water systems

  • No hot water
  • Lukewarm water
  • Water pressure
  • Water switching between too hot or too cold
  • Water dripping or pooling from the tank

Shower is Lukewarm

There might be a couple of reasons for this problem. First, check the thermostat and make sure it’s set at the right temperature. The temperature of your hot water tank should be kept at 50 degrees. So if it’s lower than this then set it 50% and see if that makes for a hot shower.

The other reason could be the gas hot water tank’s flow rate is not a continuous flow or it simply cannot keep up with the home’s demand. New continuous flow systems should have no issues with more than 2 people showering at the same time and even the dishwasher running. But old hot water systems especially without continuous flow will not be able to supply hot water at the same rate as new ones. So either you need to time showers and appliances that use hot water like dishwashers and washing machines or it’s time to buy a new hot water tank.

Instantaneous hot water systems need high water flows to ignite the pilot light. Turn your taps up high and run for a few minutes, if the hot water comes on then the issue is the flow rate, not the heater. Again this is a plumbing issue and simply call us to fix it.

No Hot Water

If you do not have any hot water check the mains supply for gas to your home. Turn on your gas stove or other gas appliances like gas heaters. If they do not light up and work then the issue could be your gas mains.

Check the pilot light on the hot water system. You need to hold down the pilot light for at least 30 seconds, hold down the button for this long before releasing it. If when you release the button and the light goes out then you may have a faulty thermocouple. These are not expensive to replace and we can do so quickly.

But before you call us to book try relighting the pilot a couple more times, follow the instructions exactly (usually inside the front cover of the unit). It can be a bit tricky but really is just a set procedure that must be followed. It’s easy to miss an instruction and not be able to light it the first time, especially if it’s early in the morning and you have not had your hot shower!

The pilot light is usually down the bottom of the unit and should show a blue flame. If it is not on then follow these steps. But generally to turn it back on the instructions are similar to the following;

  1. Turn the knob to the off position
  2. Wait 5 minutes for gas to dissipate
  3. Turn the know to the pilot position
  4. Hold the control knob while pushing the ignition switch for at least 30 seconds
  5. Then switch know to position to as instructed by unit
  6. If the pilot light goes out again wait 5 minutes and repeat these steps.

If the pilot light cannot be switched on by these steps then call us.

Water too hot or too cold

Whether you have a solar hot water system or an electric hot water system the water temperature should be even not switch between hot or cold. If your system is over 10 years old then it could be your heater is on the way out. It is not able to determine if its needs to heat up the water for the tap that got turned on. Alternatively, the gas supply to your hot water unit might not be enough, causing it to turn on and off unexpectedly. This is an issue for our experienced gas plumbers.

Low Water Pressure

Low water pressure could be caused by the cold inlet strainer valve being blocked this will reduce the water pressure coming from your instant water heater. This valve filters water being pumped into your tank so debris and rust can’t enter it. A broken or faulty thermostat can also cause this problem.
