Choosing the suitable source of hot water for your home can be a challenging task, especially when deriving a balance between energy efficiency, affordability, and comfort. With the Australian climate and environment becoming more and more sensitive, choosing either a gas or electric hot water source turns into a decision that extends beyond your household. At Hot Water Now, we understand how difficult this decision can be, and our aim is to provide you with comprehensive knowledge to make the right decision for your home and environment.

Each hot water source, be it gas or electric, comes with its own set of advantages and disadvantages. Several parameters like initial cost, running costs, environment impact, safety, and reliability lay the groundwork for the ultimate decision of choosing between gas and electric hot water systems.

Quick Summary

Both gas and electric hot water systems have unique benefits. While gas systems are renowned for their efficiency and lower running costs, electric systems offer convenience and easier installation.

Cost Comparison: Gas vs Electric Hot Water Systems

When comparing electric hot water systems versus gas-powered systems, an important aspect to consider is the financial implication. When we talk about hot water cost, we consider both the initial purchase and installation cost, and ongoing running costs. Knowing that Brisbane hot water plumbers are equipped to install both can offer peace of mind.

Generally, electric hot water systems have a lower upfront cost in terms of purchase and installation. However, they tend to be expensive to run due to the higher cost of electricity. Gas hot water systems on the other hand, have a higher initial cost but offer lower running costs in the long run.

Energy Efficiency: Gas vs Electric Hot Water Systems

The energy efficiency of hot water systems is a crucial factor, not just for the environment but also for your utility bills. In terms of energy usage, gas hot water systems in Brisbane are observed to be more energy-efficient as they only heat water when needed. This ‘on-demand’ heating ensures no energy is wasted, leading to lower energy bills. However, it’s essential to note that not all homes have a gas line connection which can limit the choice.

Electric hot water systems, on the other hand, often store heated water in a tank for use throughout the day. This leads to what is called ‘standby heat loss’, where the system uses energy to keep the water heated even when not in use. The good news is that technology has greatly improved and newer models of electric storage tanks are more energy-efficient than older ones. Therefore, it would be beneficial to consider the age of your equipment before writing off electric hot water systems entirely.

Maintenance and Lifespan: Gas vs Electric Hot Water Systems

Maintenance checks and the lifespan of a hot water system can also greatly impact your decision.

  • Gas systems, while more energy-efficient, might require more maintenance checks compared to electric systems due to their complex structure. Also, a gas hot water system typically has a shorter lifespan than an electric one.
  • Electric systems are comparatively easy to maintain and generally last longer. But when they start having issues like hot water system leaking or low hot water pressure, they may need professional attention

Safety: Gas vs Electric Hot Water Systems

When it comes to safety, there are several aspects to consider between electric and gas hot water systems. However, both come with their own safety measures to ensure they do not pose a threat to the household.

While electric hot water systems carry a risk of electrical faults that can lead to fires or electrocution, safety measures like circuit breakers and safety switches eliminate these hazards. Gas systems, on the other hand, may be prone to gas leaks or production of harmful carbon monoxide if they are not properly maintained or operated. Yet, routine maintenance checks and correct usage can keep such risks at bay.
