How Does Your Gas Storage Type of Hot Water System Work?

In Australia, gas water heaters account for about 48% of all water heaters. There are three primary varieties of gas water heaters available in Australia:

  • The gas storage type of hot water systems
  • Solar water heaters with immediate gas boosting
  • Continuous flow/instantaneous hot water systems

They all use natural gas or liquefied petroleum gas.

This kind of hot water system is an environmentally friendly alternative to traditional electric storage heaters for providing reliable hot water heating in Australian homes. You can always call any plumber Penrith available with Wilco Plumbing whenever you need any kind of servicing or repair needs.

Let us discuss in this post, how this kind of system works.

The water in a gas storage type of such hot water system is heated by a gas burner positioned beneath the storage tank. The tank is filled with cold water, which will sink to its bottom and will be heated. When you turn on your hot water tap, the water will rise to the top of your tank and will pour into the hot water piping as it warms.

A thermostat controls and maintains the temperature of the stored water with the element and also burners will guarantee that it will never fall below the allowed 60°C. Water is sent through your pressure relief valve and will come out the overflow pipe, if the water pressure becomes too high. The middle of the tank has a flue that allows hot air and gas-burning gases to escape.

The following are a few pros and cons of this hot water system?
