Gas Hot Water – Everything You Need to Know

The gas used to heat water in your home or business can come from one of two sources. It can be natural gas delivered through a pipeline or network and sometimes called ‘reticulated’ or ‘mains’ gas, or it can be liquefied petroleum gas (LPG) which is wholly contained and stored within a bottle or cylinder.

Other ‘non-gas’ options for heating water include solar, or electricity. When compared with these options, using gas as a source of energy for heating water is surprisingly versatile and cost-effective. For example, compared with solar, gas is always ‘on’ and not limited by the amount of sunlight available. When it comes to electricity-generated systems, the ongoing costs are much higher than gas.

Not all homes or establishments have access to the infrastructure (pipelines) which supply natural gas, especially in country or rural areas.  This is easily overcome by using bottled LPG which is readily transportable and can be connected directly to the source system or appliance.

For these systems, there are two main methods of producing and maintaining the heat of the water:

  1. The water flows into an insulated tank where it is heated to the desired or ‘set’ temperature until such time as the hot water is required and the taps are turned on. Such storage tanks vary in size so it is important to select a unit based on your projected consumption.  A hot tank for a sports club, for example, will need to be much larger than one for a small unit or dwelling. One small downside of this option is that, once the tank has been emptied, you may need to wait for the water in the re-filled tank to again be heated to the desired temperature.
  2. The second method for heating the water is only heated at the time of usage and thus overcomes the problem of running out of hot water. This system for producing a continuous supply of hot water can be attractive to large businesses and institutions such as hotels, hospitals, restaurants, etc., but can be a more expensive option due to the sheer volumes used.

These systems are an attractive and viable option compared with other systems due to factors of cost, accessibility, and ease of installation.  With any system, however, it is imperative that the installation and ongoing maintenance be performed by a suitably qualified and experienced tradesperson to ensure your supply is safe and trouble-free.
