Hot Water Systems

Gas Instantaneous

Looking for a quicker way to heat water for your home? A gas instantaneous hot water system may be the solution.

Also known as a gas continuous flow system, these small, compact devices provide a tankless water system that delivers hot water on demand. Safe and convenient to use, a gas instantaneous hot water system attaches directly to your wall, taking up minimal space. There are no continuous flames, so when you turn your water off the gas turns off too.

Rather than storing water they connect directly to your mains, and a gas booster that heats the water as it travels through the system. This provides a virtually endless supply of piping hot water—a continuous flow—ideal for households with a busy shower schedule.

Frequently Asked Questions

A gas instantaneous hot water system works without a storage tank. Instead, it takes water directly from the mains, and draws it into the heating system, running through a coiled heat exchange pipe. The gas burner automatically ignites, heating the pipes as the water passes through, and thereby heating the water on its way. The water then exits the system piping hot and ready for use.

Yes, instant hot water systems are incredibly safe. You only have hot water when you turn on the system, and there’s no hot water being held in a tank. As you can also adjust the temperature yourself, so you’re in control of how warm or hot your hot water runs.

When choosing the gas instantaneous hot water system that’s right for your home, the key thing you need to think about is the volume of hot water you’re using, and your budget. If you’ve only got a small home, you can easily make do with a small system. If you’ve got a busy household using multiple hot taps at once, a larger system will be a better choice. We can help you talk through all your variables, and give you the information you need to choose the instant hot water system that best suits your household.

The size of the gas continuous flow hot water system you buy depends on how much water your household uses at one time.
A good rule of thumb is:

  • 1-2 hot water taps – 16L – 20L system
  • 2-3 hot water taps – 24L system
  • 4 or more taps – 32L system

Yes, the beauty of a gas continuous flow hot water system is that you can set the temperature yourself. Units typically reach a maximum of 50°C, however if you need hotter water, you can get units that reach higher temperatures.

Our gas instant hot water systems start at around $1090 for a 10L system and increase from there.

Yes, the beauty of an instant gas hot water system is that they’re compact and easy to install. All you need is free wall space, and a home gas and electricity connection, and you can connect a new system quickly and efficiently.

If the water coming from your gas instantaneous hot water system isn’t hot, it could be for a number of reasons. To begin, we recommend that you let your hot water run for a bit (and be sure to collect the water you run and re-use it on your garden later). The water in your pipes may be cold, and it just takes time for the hot water to each your tap.

Then:

  • Check to see that it’s connected to a power source.
  • Check your stove to see if your gas supply is working.
  • Check that you’ve set the temperature hot enough to begin with.

If your hot water still isn’t hot, this indicates it may be caused by:

  • A faulty thermostat.
  • A faulty showerhead.
  • A blocked inlet valve.

If you’ve checked everything you can and there’s still no hot water, give Plumb It Right a call on 08 9577 2786 immediately.
