Choosing the Right Hot Water System: A Comprehensive Guide

Updated: Mar 2

Choosing the right hot water system is an important decision for Melbourne homeowners, as it affects both your comfort and your wallet. With so many options on the market, it can be overwhelming to determine which system is the best fit for your home, family and lifestyle. In this guide, we’ll break down the different types of hot water systems available, as well as the factors you should consider when making your decision.


Types of Hot Water Systems:


Electric Hot Water Systems

These systems are powered by electricity and are often the most affordable option to purchase. They are suitable for homes with low to moderate hot water demands, but can be expensive to run in the long term.


Pro’s: Cost effective purchase price, No Gas Required, Suitable for solar

Con’s: Large Footprint, Slow to reheat, High energy consumption


Gas Storage Hot Water Systems

Gas systems use natural gas and a flame to heat the water. They are more expensive to purchase initially than electric systems, but can be more cost-effective in the long run due to their lower running costs. The term storage system refers to the storage tank which houses the hot water while it is held before use. While some units are more efficient than others and different models hold various amounts of hot water, once the hot water is consumed in the tank, you will have to wait for the water to reheat, just like empting a kettle and waiting for it to re-boil.


Pro’s: Cost Effective and Reliable, Efficient

Con’s: Requires a large foot print, Can run out of hot water and take time to re-heat

Gas Continuous Flow Hot Water Systems:

Gas continuous flow systems use natural gas and a flame to heat the water in a small bladder instantly converting cold water into hot water. Continuous flow systems are more expensive to purchase initially than storage tank systems, but can be more cost-effective in the long run due to their lower running costs. Continuous flow systems are highly efficient as water is heated on demand, rather than stored in a tank. Continuous flow systems allow for unlimited hot water and have fast become a family favourite.


Pro’s: Unlimited Hot Water, Small and Efficient, No Gas consumed when not in use.

Con’s: Requires a larger gas line than traditional storage units, requires a 240v power point


Solar Hot Water Systems

These systems use solar panels to heat the water, making them the most energy-efficient option. They can be much more expensive to install, but offer significant savings on your energy bills over time.


Heat Pump Hot Water Systems

Heat pump systems work by extracting heat from the surrounding air and using it to heat the water. They are energy-efficient and can be used in all climates, but can be more expensive to install than other options.

Factors to Consider When Choosing a Hot Water System:

Size: The size of your hot water system should be appropriate for your household’s hot water needs. A system that is too small will not be able to keep up with demand, while a system that is too large will waste energy and cost more to run.

Energy Efficiency: Look for a system with a high energy star rating to ensure that it is energy-efficient and will save you money on your energy bills over time.

Cost: Consider the upfront cost of purchasing and installing the system, as well as the ongoing running costs. While a cheaper system may seem like a good option initially, it may end up costing you more in the long run.

Climate: The climate in your area can also impact which hot water system is the best fit for your home. For example, a solar hot water system may be more suitable in areas with plenty of sunlight, while a heat pump system may be a better option in cooler climates.


FAQs:

Q: How long should a hot water system last? A: The lifespan of a hot water system can vary depending on the type of system and how well it is maintained. Generally, electric systems last around 10-15 years, gas systems last around 10-12 years, and solar systems can last up to 20 years.


Q: Can I install a hot water system myself? A: It is against the law to install a hot water system yourself, as it can be dangerous and can also void the manufacturer’s warranty. You Must hire a licensed plumber to install the system for you.


Q: Can I switch from electric to gas or solar hot water? A: Yes, it is possible to switch from one type of hot water system to another. However, it can be a complex process and may require additional plumbing work. It’s best to consult with a licensed plumber to determine the best course of action.


Choosing the right hot water system for your home is an important decision that requires careful consideration. By taking into account factors such as size, energy efficiency, cost, and climate, you can make an informed decision that will provide you with the best outcome.
