Frequently Asked Questions

A gas hot water system works by using a gas burner to heat the water sitting in your water tank, and maintain the heated temperature. This hot water then travels through the pipes to your desired tap.

The type of gas hot water system you choose for your home comes down to a few key variables: the number of people in your house, how often you use your hot water, and your budget. We can help you work these out, and give you the information you need to choose the hot water system that best suits your household.

The size of the gas hot water system you buy depends on the number of people living in your household, and how often you use it. A good rule of thumb is:

  •  1-2 people: 90L – 150L
  • 2-3 people: 150L – 190L
  • 3-4 people: 190L – 230L
  • 5+ people: 230L or more

Our gas hot water systems start at around $1214 for a 135L system and increase from there.

If you’re planning on replacing your current hot water system with a gas hot water system, you may be able to do this if your home is already connected to natural gas. Most gas hot water systems can be installed at properties that already have a gas connection.

Your local gas provider can advise whether a gas connection is available at your property, and we can take a look at your existing hot water system to determine what’s needed to install a new system.

If the water coming from your gas hot water system isn’t hot, it could be for a number of reasons.

  • Your gas hot water tank might be some distance from your tap. Run your hot water tap until it becomes hot. Be sure to collect the water you run and re-use it on your garden.
  • The pilot light may be out. If need be, relight the pilot light and try again.
  • There may be another issue. If you’ve tried both these solutions and there’s still no hot water, give Plumb It Right a call on 08 9577 2786 immediately.
