Gas Hot Water Systems

Gas hot water systems can cost from $300 to $600 generally while being around $700 to $2,000 to install. A gas burner is what creates the warm water which is stored in a cylinder or tank. These systems are more energy-efficient, especially the 4 or 5 star units, while also producing much less greenhouse gas emissions. 

The installation often takes a day, with the pricing can be influenced if gas is already connected to the building. Both natural and liquefied petroleum gas systems are flexible enough to be installed in almost all places. Moreover, the actual unit is smaller in size and can be installed in most areas. 

Gas systems can also be compared to solar-powered systems, and there is also gas continuous flow systems to consider:

  • Solar –  using the sun, there are boosters which are installed with the system that helps in times where sunlight is poor. These booster systems can be run by gas-power, but the booster should try to no be used as much. Panels need to be big enough and of the correct number to meet the needs of hot water. Also, the roof should be compatible with solar-power, likewise, installation usually takes a few days.
  • Gas Continuous Flow – these systems are tankless with only heating the water when it is required. As a result, hot water never runs out, bacterial growth is not a concern and is extremely energy efficient.  

Positives and Negatives With Gas Hot Water Systems

Positives:

  • Cheaper to run overtime, there are no tariffs needed and natural gas is overall much cheaper.
  • Carbon footprint is minimal as there are lower greenhouse gas emissions related to gas power.
  • When purchasing the continuous flow gas heaters that means that hot water is instant and overall is appreciated. 

Negatives:

  • Installing and purchasing gas-powered units are more expensive with the size also impacting the costs.
  • With the size, they can be quite obstructing depending on the location it is installed in and is not aesthetic. 

Electric Hot Water Systems

Electric hot water systems are around $250 – $500 to initially purchase with installation costs similar to gas. Systems using electricity with a storage tank have been the most popular choice in Australia for many decades. However, this popularity is decreasing due to electricity being more expensive and also creating much more greenhouse gas emissions. The government is trying to limit their usage due to their negatives, with also heating all day meaning it is costly. Being cheap to initially purchase, these systems are actually expensive to run, larger in size and overall not encouraged. 

Electric heat pumps related to hot water systems are a better alternative to storage tanks. These use the ambient air from outside then extract the heat, similar to a reverse cycle aircon. There is a tank present and are expensive to purchase but are more energy-efficient, also creating less greenhouse gas emissions. However, they have been losing their popularity as well because of their noise, high maintenance costs and running costs.  

Positives and Negatives With Electric Hot Water Systems

Positives:

  • The units are cheaper to purchase when compared to gas systems which are usually more expensive.
  • If a continuous flow tank is installed then hot water is available instantly, similar to gas as well.
  • Because most people already have electricity connected an electric hot water system can be more easily installed. 

Negatives:

  • Tariffs, the amount of money charged for using power, can be either good or really detrimental, meaning more money can be spent.
  • The size of the actual tank can be an issue with installation as well as the overall aesthetic of the building.
  • Dangers of an electric hot water system can be severe, especially if they leak and in particular in older systems.
