Instant Hot Water Systems Sydney

Install an instant hot water system for your new home or business, and you can save hundreds in bills in the long run!

Compared to the more modern Instant Hot Water systems, the more traditional storage type hot water heaters are less water and energy efficient. Also, as water is heated in real time when needed, you cannot run out of hot water like you would with a storage hot water system.

If you’re looking to either build a house or renovate your current one, it may be a good idea to check with a plumber to see whether you can fit in an instant hot water system.

Instant Hot Water Systems Sydney FAQs

Why should I use an Instant Hot Water System?

There are many advantages an instant hot water system has over storage tank water heating:

  • More efficient in delivering hot water
  • Saves money on water bills
  • Water is safer as it is not kept stagnant in a tank
  • Saves space as you don’t need a large water storage tank

Are Instant Hot Water Systems electric?

There are both natural gas and electric-powered instant hot water systems. Currently, natural gas systems are more cost and energy efficient, but electric is catching up.

How powerful does my Instant Hot Water System need to be?

Depending on your needs, the flow rate (amount of water the system can heat) can be adjusted. A higher flow rate means more water can be heated at once, which larger families would welcome.
